Gigabit home routers are not uncommon today, but they are much more expensive than 100-megabit ones. Finding a relatively inexpensive high-speed model is a stroke of luck. But he who seeks will surely find. And, most likely, in this list there is a place for a dual-band D-link DIR-825 router. Having become the owner of such a device, you can forget about such a contradiction as 100 MB / s on the input and 300 MB / s on Wi-Fi. Now these speeds for wireless access will become a reality. If, of course, the router is configured correctly.
Description and characteristics of the D-link DIR-825 router
A simple but cute design will not become a highlight of the interior, but it will not spoil it if you place the box in a conspicuous place. In this case, you will rather pay attention to the battery of antennas, of which the router has 4: two on the side for the 2.4 GHz band and two on the back for a faster frequency range. The gain is the same for all antennas – 5 dBi.
On the top panel there is a row of LEDs that report the current mode of operation of the device, they are dim, but they can be turned off if desired.
All the main controls are located on the back: 5 Ethernet ports (blue – LAN, yellow – WAN), On / Off buttons to enable / disable Wi-Fi and WPS, USB connector. The Reset button can be found at the bottom.
The USB port allows you to connect 3G / 4G modems , which can be used as a backup source of Internet access. Or an external hard drive that will be network storage for all family members when using DLNA, Samba or FTP services.
Finally, there is a built-in torrent client, so you can download files to a disk or flash drive without a computer.
The main characteristics of the D-link DIR-825 router:
- Wi-Fi network speed in the 2.4 GHz band – up to 300 MB / s;
- Wi-Fi network speed in the 5 GHz band – up to 867 MB / s;
- the possibility of simultaneous operation in the specified frequency ranges;
- transmitter power – 17 dBM;
- 4 external antennas;
- support for 3G/4G modems;
- USB 2.0 port functions: file, print server.
Internet setup
For all brand routers, the address for entering the administrative panel is the same – 192.168.0.1 or 192.168.1.1. The default login and password is admin/admin. In order to exclude the possibility of using default values by third parties, it is better to immediately replace the standard password with your own.
However, if you have physical access to the device, a simple factory reset will restore the default values.
If this is the first turn on, then immediately after entering the login / password you will be prompted to change the last one, but this can be done later by going to the “System” tab and selecting the “Administrator password” menu item.
To connect to the Internet, select the “Network” tab and the “WAN” menu item and click the “Add” button. Further actions depend on what type of connection is used by your provider – this data is usually indicated in the contract.

Настройка PPPoE подключения
Самый востребованный в настоящее время способ подключения, отличающийся повышенной безопасностью и высокой скоростью обмена данными. Из крупных отечественных интернет-провайдеров его используют NetByNet, Дом.ру и Ростелеком.
Пошаговая инструкция:
- для параметра «тип подключения» указываем значение PPPoE;
- для параметра «Порт» (имеется в виду WAN, к которому подключается кабель от провайдера) должно стоять значение Port5, поскольку первые четыре порта – это LAN;
- указываем провайдерские имя и пароль (последний – дважды);
- в поле «Алгоритм аутентификации» должно стоять значение Auto;
- убеждаемся, что напротив параметра Keep alive имеется галочку;
- рекомендуемое значение для MTU– не больше 1450;
- you must also make sure that there are checkmarks next to the NAT and Firewall parameters;
- the IGMP parameter must be activated if the provider provides IPTV service;
- press the “Save” button.
Setting up L2TP and PPtP connections
These protocols are considered obsolete, they are slower and require an IP address, but are still used by some providers, including Beeline and Rostelecom (don’t be surprised, one of the two protocols can be used in different branches).
So, the algorithm of actions:
- select the connection method provided by the provider (PPTP + Dynamic IP or L2TP + Dynamic IP);
- leave the value of the “Port” parameter unchanged if Port5 is there;
- fill in the fields “Username” and “Password” (this is not the pair that is indicated on the label of the router, this is data for identification on the server of the service provider);
- in the “VPN server address” field, enter the value specified in the contract or user manual;
- the Authentication Algorithm field should be set to Auto;
- make sure that there is a checkmark next to the Keepalive parameter;
- the recommended value for MTU is no more than 1450;
- you must also make sure that there are checkmarks next to the NAT and Firewall parameters;
- the IGMP parameter must be activated if the provider provides the IPTV service;
- press the “Save” button.
Static IP
This type of access is practiced by many providers. Here the setup screen will be slightly different:
- specify the appropriate type of connection – “Static IP”;
- in the “Name” field, enter an arbitrary combination, although you can leave the default value;
- make sure that there is a checkmark next to the word “Allow”;
- the recommended value for MTU is 1500;
- if your provider practices binding the equipment used by the MAC address, you need to click the computer icon, the desired value will appear automatically;
- in the field “IP address” we indicate the static IP provided by the provider, we also fill in the fields “Max subnet” (usually 255.255.255.0), the address of the gateway, primary and secondary DNS – these data are also indicated in the contract;
- check the boxes for NAT, Ping, Firewall;
- the checkbox next to the IGMP parameter should be checked if the provider provides the IPTV service;
- press the “Save” button.
3G/4G connection
As a backup way to connect to the Internet, you can use a 3G / 4G modem:
- select your mobile operator from the list;
- for the “Connection type” parameter, specify the value 3G;
- fill in the “Name” field with an arbitrary name of the connection or leave it as it is;
- make sure that there is a checkmark next to the word “Allow”;
- fill in the fields “Username” and “Password” with the data provided by the operator;
- the fields APN and “Dial number” should be filled in automatically – these values are assigned to mobile operators;
- MTU field value – 1370;
- make sure that there are checkboxes opposite the Keepalive, NAT and Firewall parameters;
- press the “Save” button.
Configuring the Wi-Fi network of the D-Link DIR-825 router
Since this router is dual-band , it is recommended to configure both networks to distribute traffic. Even if you don’t have devices that support the 5GHz band, that doesn’t mean there won’t be one in the medium or short term. In principle, the settings for both frequencies are completely identical, except for the network name and password. The names should be different and it is desirable that by the name you can quickly and accurately identify which network is in question. As for the password, the recommendations are the same here, but already because of the increase in security, although most users make the password for both networks the same.
Step by step algorithm:
- select the Wi-Fi tab and click on the submenu item “Basic settings”;
- in the top line indicate the network to configure (2.4 or 5 GHz);
- in the SSID field, enter the network name, taking into account the above recommendations;
- click the “Apply” button;
- return to the “Advanced Settings” screen and in the “Wi-Fi” tab, click on the “Security Settings” sub-item;
- in the “Encryption key” field, enter the password of our wireless network;
- press the “Save” button.
To check the operation of the wireless network, the D-Link router does not need to be rebooted.
Digital interactive television
The era of satellite TV is coming to an end – a basic speed of 100 MB / s is enough for trouble-free viewing of TV in HD quality. Therefore, many providers, along with Internet access, provide an IPTV viewing service.
The D-Link DIR-825 router allows you to allocate a separate port for this purpose, through which video traffic of a specific format will be broadcast. This means that the port used for IPTV cannot be used to access the internet. The converse is also true.
To reassign the port, you need to go to the “Start” section and click on the “IPTV Setup Wizard” sub-item. On the page that opens, click on the LAN port that will be used for the IPTV set-top box, and click the “Save” button.
Port forwarding
Most users do not need this feature. Port forwarding is required in some programs (for example, torrent clients) and games. You can also find out which ports they use there.
To reassign ports, follow these steps:
- click on the “Firewall” tab;
- select the sub-item “Virtual servers”;
- click the “Add” button;
- in the “Name” field, enter an arbitrary sequence in Latin;
- select the desired connection type and protocol;
- specify the external port (single or range), and then enter the same values for the internal port;
- specify the local IP of the computer or other device that requires port forwarding;
- press the “Apply” button.
Rebooting the D-Link DIR-825 router, resetting to factory settings
Incorrect operation of the router may be due to the clogging of its memory or the use of incorrect settings. In the first case, it is recommended to reboot the device using the on/off button on the back of the router or through the web interface.
In the second, resetting the settings will help, that is, returning to the factory values. True, then you have to configure the Internet and the wireless network again.
You can perform this procedure in hardware, that is, with a button, or in software – through a web interface. The second method is more convenient, but in some cases it may not be available, for example, if you forgot your login password. The Reset button is located at the bottom of the device, it must be pressed and held for 10 seconds (if you hold for more than 15 seconds, the router will simply reboot).
In other cases, it is much easier to reset the D-Link DIR-825 to factory settings via the web interface, for which you need to enter the “System” tab, select the “Configuration” sub-item and click on the “Factory settings” button. You can also save the current settings by pressing the corresponding button so that you can return to the original state if necessary.
Firmware update
Few routers in this price range are able to update the firmware over the air, but the D-Link DIR-825 has such an opportunity. The corresponding function is available in the “System” tab in the “Software Update” section. You should go here more or less regularly and click the “Check for Updates” button – if a fresh firmware is found on the manufacturer’s server, the update will be performed automatically.
In some cases, a manual firmware update may be the preferred method (for example, you want to downgrade to a lower firmware version).
You can download it from the company’s official website by clicking on the “Downloads” button, selecting the desired version and clicking the “Download” button. Here you can also see the changes in a specific firmware version.
To flash the router, click on the “Local update” item.
