In this article we will customize a very popular D-Link DIR-615 router. I will write an article on the example. And if you have another model, nothing terrible, almost everything coincides there. This manual is suitable for many D-Link routers. I will try to write about everything in detail and in your understandable language. Telling about the router very much I will not read my feedback and another useful information About DIR-615 / A, you can link above. I just say that this router is well suited for home, or small office. It will easily provide stable Internet access for your computers, telephones, tablets (Wi-Fi) and other devices.

As for the configuration of the D-Link DIR-615, everything is very simple there. And if your provider uses the connection technology dynamic IP, then you will sufficiently connect the router, and the Internet will already work. You will only need to install a password on the Wi-Fi network and change the network name if you need. I don't like the fact that the settings in the D-Link are virtually in each version (in appearance). I have a routing control panel. And therefore, the settings of your router may differ from those you will see in this article. But it can fix the firmware update.

Customize D-Link DIR-615 will be according to such a scheme:

• Connection and input to the control panel on D-Link DIR-615
• Configuring Internet on D-Link DIR-615 (connections to the provider)
• Wi-Fi Setup network and password change

And now, about everything more.

Connect D-Link DIR-615 and go to the settings

Connect the power to the router and turn it on. If the indicators on the front panel of the router did not light up, then check whether the power with the button on the rear panel is enabled. If you configure the cable router, then take the network cable that comes with, connect the router with the computer. One end of the cable is connected in black Lan. Connector (in 1 of 4), and connect the second end to the computer's network card (laptop). Connect the cable from the Internet provider in yellow WAN. connector.

If you do not have a computer with network card, or no cable, you can configure everything on Wi-Fi. You can even with a phone, or tablet.

You can also change the administrator password, which is used to access the router settings. If you did not change it, or changed, but already forgotten, then you can do it on the tab System - Administrator password.

Specify twice the new password and click Apply. Do not forget to save the settings.

Be sure to write down somewhere this password. If you forget it, you will not be able to enter the control panel, and you will have to reset the settings.

Afterword

Fuh, I'm tired :) I will not write anything else. If you have questions about the article, ask in the comments. I hope you managed to configure your router.

- This is not a completely difficult process. Many fall into panic, as soon as they hear "you need to independently connect Wi-Fi." But it is not worth it to be afraid, because with the instructions offered below everything will be easily and easy. The setting will be carried out in two stages - setting up on a computer and on the browser website. Let's proceed.

1. We follow this path: "Start" - "Control Panel" - "Network Connections" - " modem d-link DIR-615. " Click on the last right button and open properties. In the proposed window, set the parameters as in the picture:

2. Now proceed to installing the router parameters in the browser. We go to the 192.168.0.1 page. Default - Admin, about the password field - empty. It opens standard. We find "Manual Internet Connection Setup". It needs to fill all empty lines. Username, password and addresses must be found from the provider. They can be spelled out in the contract, and if not - you need to call technical support and ask to inform them.

If you have reached this stage, the Internet on your computer already has surely appeared if you have not forgotten connecting the network cable to the router. But in order for he to distribute the wireless network, we do the following:

We go to the "Wireless Settings" - "Manual Wireless Network Setup" and fill empty strings. Network name and invent it yourself.

It remains only to press on the right on the control panel Little icon with available wireless connectionsSelect the invented network name and enter the password. Wi-Fi should earn.

This is so easy to configure the Internet and Wi-Fi on the D-Link DIR-615 router. We hope that this router will serve you for a long time and reliably, will not make pills from headaches. Do not be afraid to take the initiative in the settings, because this process takes only a few minutes and will be free of charge.

Connect your home to the Internet is very simple and most often even cheap. However, not all Internet companies provide the setting of the router for you. Therefore, the first user, the buyer, has to independently configure the router.

So that no problems arise in the setup, just follow our simple instructions by setting up D-Link DIR-615.

Characteristics and appearance of the router

About characteristics D-Link 615 to say almost nothing, for all such devices they extremely similar to each other. 802.11n technology, embedded antennas, 4 network ports, a frequency of about 2.4 gigahertz are used. Data transfer rate through a cable up to 100 megabits per second, through a wireless network up to 300 megabits per second.

On the front panel there are several, and if more accurate, 8 light bulbs performing the role of indicators:

• The first indicator "Power", this light bulb is responsible for the diet of the device, connecting to electricity.
• The indicator signed "WPS", it shows the status of this function.
• LIGHT "INTERNET". It is not difficult to guess what she answers. This is a state of connecting to the World Wide Web.
• The remaining indicators are responsible for the ports. The first of them "WLAN". This WiFi mode.
• Another 4 connections through the LAN cables.

On the side panel there is only one WPS button that can quickly connect.

On the back panel there are two special places for fastening our device to the wall. And below are different ports and buttons:

• First go 4 local ports where you can insert a network cable for connecting home Computer directly.
• One port for connecting the Internet.
• The button located inside the opening "RESET". To press it, you need to use some kind of thin object, for example, a clip. Click this button for 7-10 seconds. After the device is restored to the factory settings.
• Power connector router. You need to insert the power cord, which the other side should be in the outlet.
• Routher power on / off key. Using this button you can restart the router.

After we exactly learned the location of all the connectors you need and indicators, you can go to the installation rOTETER D-LINK DIR-615, I will perform the setting a little later.

Installing a router in place

Choose a place that would be about in the middle of our house or apartment. This is in order to be about the same signal in different rooms. Nearby should be a socket and there must get the Internet cable.

We attach it to the wall, insert the power supply, turn using the power button, connect a laptop or computer to it via LAN port. Here there is another moment, important in further configuration. If the Internet immediately appeared on the computer, it is possible to determine which IP address from your provider.

If the Internet immediately appeared, then you have a dynamic IP address. On the WLAN wire, the provider incoming traffic is immediately redirected to you.

Questions how to connect or how to install a 615 router for Rostelecom, it should not occur because each connector meets its wire.

To make a static IP, you need to execute the D-Link ports 615 ports. Move directly to the settings of the Link. About how to open ports on the D-Link router, we will write in a separate article.

Complete configuration of Device

To begin with, immediately after connecting the router 615s to the computer, it is worth resetting the settings. So, to set up D-Link DIR-615 from the very beginning:

Reset

To reset the settings you only need to press the "Reset" button, located on the reverse side of the apparatus in the hole. Press the key for 7-10 seconds. All D-Link DIR-615 router settings will become factory. This is a particularly important step for those who bought the device after someone's use.

Also reset can be done by those who forgot the password. To put the password and the default login on the Wi-Fi D-Link router. After reconfiguration is performed.

Problems of firmware

After that, it is worth noting that on routers usually costs old version Firmware, the most ancient. You can also work with it, but it is better to take care of your nerves and forces - download the update. Download yourself new firmwareTo keep up with the whole world.

On the bottom of our device there is a serial code and a bunch of other updating information. We are interested in the line "H / W VER. :**". On the site of the stars should be the version of your d-LINK router DIR-615. We have this K1.

Now, before entering the settings, go to the official website http://ftp.dlink.ru/pub/router/, we do everything clearly in screenshots. Here is an example update to K1.

Now we have software for our router that we needed to update. Now, in fact, learn how to flash the D-Link DIR-615 router.

To do this, you need to go to the settings to the router debugging site in the router settings, this is address 192.168.0.1 or 192.168.1.1. Enter the name and password - "Admin" is the factory settings of the router D. Now you can see the interface. The firmware version is written on top. If this is version 1.0.0, then go to "configure manually". Then "System", choose "Update software", Choose the file that was downloaded a little earlier and updated the modem.

On this flashing is over.

Debugging Connections to Web

We go into the same router settings at 192.168.0.1, enter Admin / Admin, click "Login". In the updated firmware, press the advanced settings below. Then chose WAN in the list, this item is located in the "Network" block.

Press the "Add" key, thereby creating a new network connection. Here you need to enter the data that the provider provides you. Connection type, login and password must be specified in the contract, do not forget to clarify these moments from him. It is necessary for connecting to the Internet. Click "Save".

Now the Internet should appear on the local network, that is, on those computers that are connected via LAN local cords.

Debugging wireless network

In the "Wi-Fi" block, we click on the general settings. All this is in the same extended settings if anyone forgot. Here click "Enable wireless connection", We put a tick and save. As you can see, setting up the Wi Fi router D-Link DIR-615 is a fairly simple task.

After that, in the SSID field, we enter the name of your wai fi, it will be visible to everyone. Write in english. We choose our country, the channel is automatic and the mode is the same.

Now in the Wi-Fi block, select the security settings. In the first WiFi setting, we set WPA-PSK2. In the next field where the encryption key. This is a password from Wi-Fi. On the same tab, the answer to the question is how to change the password or how to put a password on Wi-Fi.

Now you have figured out how to configure the D-Link DIR-615 router thanks to our step-by-step instructions.

Quickly you internet!

Router DIR-615 - Another representative of the D-Link DIR line device with support for the modern location of the local network and cable Internet. Its configuration is nothing special from the settings of similar compatible models of routers.

Routher Review D-Link DIR-615

The DIR-615 router includes: the device itself, two wi-Fi antennas, disk with software, power adapter, LAN cable, user manual.

The DIR-615 package includes everything you need

WAN-port is located apart. Any cable Internet tariff is supported - up to 100 Mbps, the same speed on the local network by cable. However, Wi-Fi wireless network (communication between devices) is three times faster.

LAN ports are located aside.

The indication panel is very informative - as in the vast majority of home routers.

Power indicators, modes and network DIR-615

The number of PCs and laptops in the cable network with DIR-615 can be easily increased from 3-4 to the required amount using additional devices LAN-HUB and purely wired routers for every taste - from the simplest (other routers) to professional multiphore devices.

Table: DIR-615 characteristics

Now the DIR-615 router will cost 1000 - 3000 p., Depending on the store or trading network, the purchase region, delivery cost. Purchase router DIR-615 online on sites chinese storesFor example, Aliexpress, it can be done three times cheaper (including free delivery to Russia for 60 days) than in domestic shopping center.

Setting up the router DIR-615

Before connecting the router to a PC or laptop, check that network adapters Wi-Fi and LAN are configured to auto-capture IP addresses - it will free you from the setting on each of the client devices.

Check IP settings on a PC or laptop

In Windows 10, do the following.

Now go to the DIR-615 settings.

If the past IP settings are still useful to you (you will connect to the network again through the router, in which the DHCP server is not enabled) - use third-party programsStarting the profiles of settings, for example, NetSetman.

Log in to the router settings and password shift

After auto receipt of IP addresses on a PC or laptop, many routers are turned on by default DHCP server. For the convenience of users, all commands and menu items are translated into Russian.

The router will restart, you will enter it with a new password.

How to configure Wi-Fi on the DIR-615 router

After changing the password on the DIR-615 router, the second front line is checked - WPA-2 encryption in wi-Fi network.

The DIR-615 router will restart with the new settings of your Wi-Fi network. Use the WPA-2 key just specified in the router settings.

PPTP setup on dir routers

As an example, an alternative web interface for the DIR line routers, other than the "native" line, issued by D-Link and also suitable for the 615th model.

DIR-615 will restart and will be released using PPTP. If the provider uses the PPTP protocol with the STATIC IP service - DNS addresses will need to be assigned manually.

Setting L2TP on DIR-615

Like PPTP, L2TP protocol is the following PPTP development of encryption in VPN networks. Both algorithms are used, for example, if you urgently need to "hide" from Internet censorship, for example, bypass the prohibition of torrents acting in your country. Many Russian providers, ranging from Rostelecom, support both these varieties of traffic encryption.

As an example, the same corporate web interface DIR-615.

1. Give the "Settings - Internet - manual configuration of the Internet connection".

   Press the transition button to manual setting L2TP.

2. Select the link type (L2TP connection). As an example, communication without the service "Static IP".

   To continue, go to the following parameters DIR-615

3. Enter the username and password from the contract, server name. As an example, the connection to the GPON (fiber optic Internet) from Beeline.

   Enter all the L2TP parameters required by the provider

4. Turn on the auto-connection when the connection breaks and enter the MTU value less than 1450. Click the "Save Settings" button. If you connect the "Static IP" service from the "Beeline" (or other provider) the main IP of the gateway and the DNS address.

The router will restart with new L2TP connection settings and will automatically enter the network.

PPPOE setting on routers

PPPoE connection, being high-speed, requires a username and password - if only you do not have the "Access to the network without settings" service. The latter is relevant for cellular providers using the IMSI SIM card identification - there is no need for cable providers, login and password from the contract.

As an example, another alternative web interface from D-Link, differing from classic gray orange.

In general, the company B-LINK, the release of the routers of different modifications relating to the same model uses different design and significantly different functionality on them, although the essence of all operations does not change.

Click the "Add" button and enter the following parameters: Your profile name (arbitrary), MTU value less than 1450. Select the PPPoE connection type, enable the "WAN" option, select the 5th port and deposit the MAC address with the specified in your contract.

Check that all values \u200b\u200bfor PPPOE are optimal.

Enter your logs and password (twice) from the contract, select Auto Authentication Mode, enable the "NAT" and "Network Screen" functions.

Special attention is paid to the login and password

Click the Save button, then select your connection profile (in the default gateway column) and press the Save button again.

New settings will be displayed next to (or instead) an IPoe

DIR-615 will automatically enter the Internet after restarting.

How to set up static IP on DIR-615

Static IP settings may not require login and password input from the contract.

1. Give the command "Network" - "WAN" - Add »Button to create a new connection profile.

   Adding a new Static IP connection profile

2. Select Port 5 and enter the connection profile, assign MTU less than 1450, check the faithfulness of the MAC address.

   Check all the same initial parameters for static IP

3. Select Static IP Connect and enter the IP of the Gateway and DNS received from the provider, click the "Save" button.

   IP and DNS addresses are issued by the provider

4. Give the "System - Save Settings" command.

   Click on the menu item to save the setting.

DIR-615 will start with new settings and reconnect to the Internet.

Survey ports on DIR-615 routers

The ports of ports between routers are needed, for example, to optimize the speed of torrent distribution, the settings of the local gaming server, etc. The latter has the meaning and in the local city network - on tariffs with speed \u200b\u200bInternet Up to 100 Mbit / s, but having an intracity (or intramaxpusary, for example, between several close-based university buildings or hostels) speed up to one or more gigabit per second.

As an example, a blue (Russified) web interface D-Link.

1. Give the command: "Firewall" - " Virtual servers"-" Add "button.

   Unlike the profile of the usual connection, the server is configured differently.

2. Select an arbitrary profile template, enter the connection name, select Protocol external connection to the network (for example, you use pPPoE connection). Select a protocol, for example, TCP / IP.

   Enter the required values \u200b\u200bfor port forwarding

3. Specify the range of external and internal ports. When bug errors on one of them, the router will automatically switch port numbers in these intervals of values \u200b\u200buntil the operating will be found.
4. Assign the internal IP address of the server or router of the local or intracity network that runs the role of the server to which you want to open these ports. Click the "Save" button (or "Change" if an already existing connection profile is changing). You will have a new / changed connection profile with port promotions.

   Surveying ports A DIR-651 is completed

5. Click Remove the "Save.

You can restart the router and check the performance of the "spent" connection.

Setting up IP television on DIR-615 router

Settings "IP TV" services are united for many routers of the DIR line. The service must be connected on the factor of the provider.

The port assigned to IPTV will not be used for the usual Internet. Assign to IPTV one of the free ports of the router DIR, and not another port in which the LAN-hub is enabled with multiple cable connections to different PCs - otherwise these computers running in the ligament on this port will be programmatically cut off from the network.

Turn on your console and connect it to the selected LAN port. The monitor should displays the list of IPTV channels.

Setting up LAN and DHCP on the router

The DHCP server distributes local IP to all gadgets and PCs that are not configured to specific values \u200b\u200bin your local network. As an example, a classic web interface.

The router will restart with new DHCP settings, your PCs and gadgets are reconnected, then your network will enable Internet access.

Setting up DIR-615 as a repeater

The repeater mode allows you to expand the Wi-Fi network coverage area. Like any real 3G / 4G repeater, the Wi-Fi virtual repeater allows not only to solve the problem of the "last house / block / mile" with a coating, but also to create a full-fledged wireless local network of any topology (chain of routers, "star", "tree "," Cloud "or" Ring "of devices) with one or more Internet access channels. The full-fledged network in the image and likeness of the cellular network is obtained - with a much smaller "cell" (routers) radius (routers), without a cable or a volc to each of these "base stations", without phone calls and SMS / MMS, but not inferior to the Internet technologies on 3G-based 3G (UMTS).

Virtual hot spot and repeater modes support almost all modern Android gadgets having wi-Fi technology Direct ("Distributor of the Internet") and sourid appobtained from Google Play. or from third developers. No problem Wi-Fi Router With a tablet or smartphone (and vice versa), operating in the repeater mode.

Wi-Fi repeater mode is practical for the most sophisticated users. As an example, the classic D-Link interface.

1. Give the "Settings - Wireless Network" command and select Bridge Mode with Access Point (this is a virtual repeater). In others d-Link firmware Dir This can be the "Client and Access Point" mode.

   The DIR-615 router is configured a little different than routers of other brands.

2. Enter the Wi-Fi network name. Select the channel manually - on which the source router is broadcast. When you automatically select the channel, turn on the "Auto Channel" feature.
3. If you are interested hidden networks Wi-Fi (These routers do not give out their SSID on the air), MAC addresses and WPA-2 settings are known to you, check the "Enable Hidden Wireless Network" feature.
4. Select Wi-Fi security - "Enable Improved Wireless Safety", if the desired router uses this level of security. You can also use binding to source routers for MAC addresses if you disable this improved Wi-Fi relay security.

   Purpose of MAC addresses manually for static configuration Bridge-AP

5. Select the encryption algorithm used by the source router.

   The last step remains - and the repeater DIR-615 is ready for work

6. Enable Personal Identification by the WPA-2 key and double-click the password from the Wi-Fi relay network, click the Apply Settings button.

DIR-615 will restart in the repeater mode, turning off from its own cable Internet. After reconnecting gadgets and PCs to the router-repeater, an Internet traffic auto hatching will occur from the source router (if it is the cable PON, 4G access or taking from the next in the created Router repeater chain or a gadget operating as a virtual hotspout). You can enter the network.

Reset, preload and save settings

For ease of settings, D-Link has reduced work with the DIR / DAP line routers settings in one submenu. Give the "More - Save and Restore" command.

To save the DIR-615 settings, the Save button is used to preload already saved in separate file Settings - shape of the path to files with the "Overview" button and the "Update Settings" button to reset the unsuccessful settings - the Restore button. After each setup update, the router is restarted.

DIR-615 firmware update

As an example, one of the options for the DIR-615 interface. Download the firmware file from the DIR router manufacturer.

The router will connect to the network, provided that the default settings are valid from your provider. It happens when the provider itself simultaneously supports multiple protocols (without dynaming) - dynamic IP, PPPoE and PPTP / L2TP encryption, leaving the user with the ability to choose.

Restart DIR-615

Restarting the DIR-615 router is carried out as pressing (and with hold on half a minute) to the entire well-known reset button located behind, near the LAN noddes and via the web interface.

Often, restart the router through its settings faster, if the actions are worked out, with a successful circumstance, - than keeping the edge of this entire button.

Give the command: "System" - "Restart" (or "Save and restart" if you change the settings at the same time).

Restart initialization DIR-615

The router will restart and re-enter the network.
