DNS means Domain Name Server, this is the server that is used to conversion a domain names of web sites in accordance with IP addresses of servers where this domains are hosted. For example, if you enter the www.microsoft.com address, then your browser does not know to which server its need to connect to perform a page request for www.microsoft.com domain. To get the address of the server hosting, firstly your server will try to establish connect with a nearby DNS server to obtain there IP address of the hosting server. If the local DNS server cannot find this information, then it forwards the request to another DNS server that has more conversions of addresses. Once the address is discovered, it will be send back to your browser and the browser will be able to establish connections with entered web site.

If there is a failure of your local DNS server or a connection with the next DNS-server cannot be established, then domain name that you entered to your browser will not be conversed to the IP address and your browser will not be able to establish a connection. This error usually invisible to the Internet users, because browser will try to load the next page until domain name will be obtained. Thus, everything except the DNS server can work fine, but you cannot use the Internet.

There is a great opportunity to minimize the factors that can lead to failure of the DNS server. Instead of using the DNS server, provided by local Internet provider, you can use the Google or

OpenDNS DNS server.

IP addresses of Google DNS server:


IP addresses of OpenDNS DNS server:


You can set abovementioned IP address as your standard DNS server and every time your browser will need to converse the domain name to the IP address, it will quickly send request to these servers instead of local DNS server. Considering that the Google and OpenDNS servers are very reliable, the chance that they will not work, will be much lower in comparison with the local DNS server.

During setting up the router, you can be faced with various problems:

  1. Failure of hardware. The router does not work properly, and this leads to the fact that one or all of the network protocols do not work.
  2. Failure of software. Operating system on your computer or on a mobile device do not functioning properly.
  3. Incorrect settings. Incorrect configuration of software or hardware.

For the correct diagnostics of router problems it is important to determine group of problems. You can see the following operation manuals for the classification of your problem.  

Failure of software

  • Read the operation manual to see which light indicators should be lighted when the router is working properly. Usually this is a check light indicator, WAN-connection light indicator and the light indicator for each Ethernet-connection to the router. If one of the light indicators is not working properly, use the router troubleshooting guide to and try to reset the router to its factory settings.
  • When you connect one of the router network connectors to the computer via cable, then the relevant light indicator of router should be flashing. Light indicator will flash only when computer is turned on and the operating system is loaded.
  • If your device is determined by the network with the IP address which starts at 169.254, it means that something wrong with your router. The address that starts with 169.254 digits, assigned to the device if the router cannot assign the correct network address.

Important! In any case, try different ways of solving the problem before resetting yourrouter to factory settings, because reset function will delete your settings and returns the router to factory settings. Also, save the settings of Internet connection in your router's configuration interface before reset it to its factory settings so that you can enter them again after rebooting the router.

Failure of hardware

  • Your settings are correct and configured according to the description in the operation manual, but your network, however, does not work. Also make sure that the hardware is working properly. If both of the above facts are true, it is possible that a software error occurred on your device or on your router.
  • To determine whether there was a problem in the configuration software of the router or computer/mobile device, try to connect other devices to the router. If another device is working properly, then the problem has occurred on your computer/mobile device. If the connection still has problems, then problem caused by router.

Incorrect settings

If you can establish a connection using the router management interface and still use IP address or other IP address assigned to router, but it is still impossible to establish an Internet connection, then this means that the cause of problem in incorrect settings of router. If you using in your network router and modem together, note that the router shall be able to recognize your modem and the modem configuration shall be correct. For instructions on configuring a modem, see manual provided by your Internet provider, as well as the operation manual of your modem.

Determining the IP address of the router may look like a simple task, and this is certainly true for a computer specialist. But for an average user this task can take a lot of time and efforts. In this quick guide, you will learn the steps how you can find out the address of your router at the lowest efforts.

Firstly, try to enter three following IP addresses in your Internet browser and see if you will continue to the router management interface. The following IP addresses correspond to 90% of the routers that are currently used at the consumer market. If instead of opening of the router management page, you will be redirected to the search results again or you will see a blank page, then, probably, your router do not using this IP address.

If you do not go to the router management page after typing the abovementioned addresses, you can try the following actions.

iOS devices

  1. Click the «Home page» button.
  2. Go to settings.
  3. Click on «WLAN» button
  4. Select the WLAN wireless network to which you want to connect.
  5. IP address of your router appears in the router bar. You can see the current IP address in the IP address bar.

Mac OS devices

  1. Open the system settings from the Apple menu.
  2. Click on the network in the «Internet and wireless networks» section.
  3. Select the current connection from the connection list on the left page.
  4. Click on «Advanced ...»
  5. Select the "TCP/IP" tab.
  6. Router IP address is the digital address next to the «Router» column, which will look something like this:

Android OS devices

Unfortunately, there is still no way to determine the IP-address of the router on the Android operating system via standard interface. To do this, you need to use either a special application or device with a different operating system.

On a PC with Windows OS

  1. Open the «cmd.exe» in the «Start» menu. The program is very easy to run by clicking on the «Start» button and enter «cmd». You will see the application cmd.exe in the search results.
  2. In the window of «cmd.exe» program, enter «ipconfig /all» and press Enter.
  3. Find the «Default Gateway» line. It will contain the IP-address of the router.

Most of the routers shipped to customers with default passwords. In order to enter for the first time in the router management interface, you will need to enter the default password in data entry form. Typically, this password is specified in the documentation that comes in set with the router.

If you do not have documentation (you got a router from someone as a gift, or buy a router that was previously used, or simply lost your documentation), you can try using the default passwords for the router and see if they work. The standard passwords are the same for each router of specified brand and specified model. If you search only by brand and model of your router, you can find the default passwords and usernames.

If you think that your router password has been changed and you do not know the new password, then you have is one more opportunity - a hard reset of the router. For specific model of router you need to check and determine how you can reboot it (usually you will need to hold down a specific button on the router for a specific amount of time).

Below is a list of the most popular user names and passwords for routers, which cover a significant number of brands and models of routers. If your router is not represented here, then use the Internet search engine. You shall search by entering a specific router model and adding the word «password». Probably, such request will give you the correct answer. We are working on a database of routers passwords for this web site.
