Hello. This is my first post and I am going to cover router IP on this blog with possible issues and troubleshooting.

For the start we need to know what is 

192 168 1 254 is an IP address. To see what is an IP address consult this wikipedia article. Anyway that IP address is an address from the private range of IP addresses. This private range is created by IANA (body which controls assignment of IPs) in order to be used on private networks. This means only local network devices can have IP from given range.

Some devices are "bosses" in the network (such as routers). Those devices control which IP address will be given to each device in local network. Those devices also control and route traffic between local network and the internet. Because of importance such devices have default IP address which is always theirs e.g. you control and access to that device through that given address.

So in short, is a default IP address given to some router models. There are virtually hundred of brands and router models which use this IP and it is almost impossible to count them all.

If your router has this as default IP you can open the web control panel of your router by typing 

into the address bar of your browser.

It will ask for username and password which you can find in your user manual which you got with the router. Off course your computer must be connected to your router through local area network. Once you are logged into router web control panel, you will have ability to setup wireless encryption and connectivity password, set up firewall, edit network settings and do similar config stuff.

Sometimes you will get error opening it and that's why you ended up here searching for solution...

If you can not open then problem must be in some of the following:
  • Your computer is not connected to the LAN
  • Your router default IP is not
  • Your router is broken not working

If your IP address it not working try the following to resolve the connectivity:
  1. Restart your computer
  2. Restart your router
  3. Check the cables if it is wired router
  4. Try connecting router to another computer
  5. Reset your router to factory settings (there is usually reset button or reset hole at the back of your router) unknown password

If your router ask for username and password and you forgot it, then Reset your router to factory settings.

If you never changed or inserted password then try logging in with default username and password for your router. Usually default username and passwords are:

username: admin
password: admin

username: administrator
password: administrator

username: admin
password: blank (nothing typed)

username: root
password: admin

or any combination of above usernames and passwords. If none of those working try consulting user manual for your router to see the default username and password or you can simply google model of your router with the words "default username and password".

Which routers have as a default IP?

Every router brand at least has one model which uses this IP as a default address. Some of the most known brands are: 2Wire, AirLive, TP Link, Billion, D-Link, Motorola, NetGear, Netopia, Zyxel, Siemens... But the largest number of routers with the as an IP has the Thomson, with 33 models having this IP as a default IP.

2Wire Routers with the default IP Address

2Wire, Inc., was (between 1998 and 2010) a home networking Customer Premises Equipment (CPE) manufacturer that provided telecommunications companies with hardware, software, service platforms, and remote CPE management systems. The company was headquartered in San Jose, California, in the Silicon Valley.
Following routers (in the table bellow) from 2Wire are having default IP address

Manufacturer Model Default IP Default Username Default Password
2Wire 1000HG admin admin
2Wire 1700HW admin admin
2Wire 1701HG - -
2Wire 1800HG wireless none
2Wire 2700HG-S admin admin
2Wire 2701HG-G - -
2Wire 2701HG-T - -
2Wire 3000 series - -
2Wire 3800HGV-B - -

In the last column are default IP and address for it's respective router.

Fixing by Clearing Cache

Sometimes you might have need to flush dns cache to access That might happen if you tried opening while it was offline. Once you fixed connection to the IP it is still not working. That's because your DNS cache remembered it is down.

To fix it you need to clear cache and force the connection retry. Luckily it is very easy to do it. Here we will explain how to clear cache in Windows, Linux and Mac OS X.

Clearing the DNS Cache in Windows

All you need to do it is to execute ipconfig /flushdns command from your windows command prompt or from run section from start menu. So do this commands and it will clear your cache.

  1. Click on the "Start" button.
  2. Click "Run".
  3. Type in the "ipconfig /flushdns" without quotes.
  4. Hit "Enter" on your keyboard.
Done. Try now opening your router by typing its IP. 

You can also open windows command prompt as we said Start -> All Programs -> Command Prompt (that thing with c:\) and type there ipconfig /flushdns then hit enter).

Clearing the DNS Cache in Linux

Cache clearing in Linux is done by restarting the NSCD daemon. Do it in the following way.
  1. Open Terminal
  2. "Type /etc/rc.d/init.d/nscd restart"
  3. Wait until it say it is done.

Clearing the DNS Cache in MacOS X

Cache clearing in Mac OS X is done by running tool dscacheutil with a flushcach parameter in the terminal.

  1. Open Terminal
  2. Type dscacheutil -flushcache
    ex: bash-2.05a$ dscacheutil -flushcache
  3. Wait until it say it is done.
If your is not responding then error is on some other place.

What is is private ip address. IANA designated it as private because of lack of IPv4 addresses. Those private IP addresses are usually used on private subnetworks behind and computers in it connect out with the help of routers which are routing traffic between outside and inside network. 192.168.100 is default IP address for minor number of router devices.

Is default address of my router?

It might be.  Certain devices use, but manufacturer is the one responsible to assigning default IP for their router products, yet you can change the given default address wheneever you want. To check is default address for your router, open Windows XP command prompt and type ”ipconfig” , then check the value in “Default Gateway option” section.

I can’t open it

Number of causes can exists for this. Please refer to frontpage of this site and check causes for not opening, same rules apply on both default IP addresses.

Can I change 192.168.100 on my router?

Yes. Every router default address can be changed. Some routers will require of you use of telnet but most of them will not. You will have such option in router web control panel (that thing when you type your router IP in your internet browser). For details how to change specific router default address please refer to user manual you got with your router. FaQ

What is is an IPv4 address from private range. IANA assigned it there because of lack of IPv4 addresses. All addresses from private IP range can be used unlimited times on different subnets. It is also default IP address for large number of internet routers from different manufacturers.

Is default address of my router?

That depends. Some routers use, but manufacturer could assign any address from IPv4 private range as a default router IP address. You can check is default address for your router by opening command prompt in windows then type  ”ipconfig” and look for address under “Default Gateway option”. is a default address for my router but I can’t open it?

There can be many reasons for that. You should check cables, connections, power and many other things to make sure your router, network or pc is working properly. Check this article and points to see does your router work properly. does not fits my needs? Can I change it?

Sure you. Every router default address can be changed. Some routers will require of you use of telnet but most of them will not. You will have such option in router web control panel (that thing  when you type your router IP in your internet browser). For details how to change specific router default address please refer to user manual you got with your router. is asking for password?

Some manufacturers will setup default password for your router. If you did not setup any password then refer to user manual to see which password is default one for your model.

I bought another router with the same IP and now one is not working properly? What should I do?

Two devices with the same IP address in one network can’t function properly. IP is unique identifier of network computer or device. So you should change default IP address on one of your routers and everything will start working.

What are other common default router IP addresses?

Other common router IP addresses are,,,, and
