No connection available wired or wireless. I have a WRT160N that has been in my house for a couple years now working fine. As of this morning, we lost internet connections on all of our wired and wireless computers. I tried connecting my desktop directly to the modem and was able to get internet fine. As soon as I try to add in the router, the internet goes out again. I have tried returning it to factory defaults and have also done a hard reset by holding the reset button on the back for over 30 seconds and neither have worked. I upgraded the firmware too also to no success.

Since you have not given what version of windows you are using, i am giving a generic step to test where the issue is. Please connect this computer directly to the router or the DSL/Cable modem you have and check if it is working fine with internet. If it is working then the issue is not with your firewall or setting. If it is not working even by directly connecting with a wire, then the issue could be with a firewall

open http://192.168.1.1 and go tom wireless page and change the radio band and channel both to auto ...

or simly u can use the following as well

Radio band is : 20mhz

Standard channel : 6

Check the IP address on the Vista wireless network connection. Make sure that there is not static IP address on the wireless connection. That could be one of the reason.

Is there any computer connected to the router ?
If not then connect the computer to the router. If you are connecting a wireless computer then disable the wireless connection on the computer. open the set up page of the router. change the wireless network name to something different that you never used before. change the standard channel to 11. save the settings. Try to connect to the wireless network. Check if you see the new network name ? If you see the new then try t connect and see if that works.
This router WRT160N has issues with the firmware.

I made it an unsecured connection and everything worked. Not ideal solution, but it worked.

To setup a wireless connection on a computer, the wireless card in the computer needs to be configured with the wireless router's settings.

Do you have any other wireless computer working ?
try changing the channel of the wireless network.

Get Network Magic ... download for evaluation.

This is a tremendous network management tool well worth the $. If you dont pay, you can still use most features.

Get it and use it to get your connection going at least.

Let me know what happens

a

Check on your cables makes sure they are inserted properly and the cord should be free of kinks, scrapes or loose connections......Also check the back of your computer make sure your ethernet card (the one that has the green lights/LED's) is seated properly (not loose)....

Good Luck.....hope this helps...if not let us know....cheers

Does the router work with the wired port connection? It's entirely possible that the router just went belly-up on you ...Linksys is an awesome brand, but sometimes it happens.

If the wired part works, the wireless transmitter inside may have gone bad. Best to just get a new one for about $50 ...but keep the old one in case you need a wired connection somewhere else around the house :)
