Wireless connection won't stay on, it comes on for 1 or 2 seconds then goes out for 30 sec., then back on for 2 seconds . I've unplugged it, then plugged it back in. Same. I have not reset it because LAN connection works perfectly with cable.

check the power pack inside it because it may not be compatible with it

If you are resetting because you forgot the username and want to reset the router to factory defaults(you would have to reconfigure your router completely), you should use a 30-30-30 reset. This is done buy holding the reset button for 30 seconds, while still holding the reset button unplug the power cord for 30 sec, while still holding the reset button plug the power back and keep holding for another 30 sec. In short you hold the reset button for a total of 90 sec and have the unit unplugged in the middle of that time for 30 secs. Or you can simply try holding the reset button for 30 sec and see if the defaults (admin) are now working or not. As for the computer, it does not have to be off, I actually prefer keeping it on because you can test the router connection right away.

Hi,

Please try to access the router's configuration page by accessing 192.168.0.1 using a computer that is wired on the router.

Reconnect the computers as you had setup originally when everything worked.

Unplug the modem and the router. Wait about 30 secs.

Plug the modem in. Wait about 30 secs.

Plug the router in.

See if you can gain access to the internet. If not, do Start|Run|Cmd

At the window, type ipconfig, and reply back what it says.

If it works, please let me know as well, and don't forget to rate my answer.

Check the connections that plug into the Block assembly. sounds like a connection issue.

If it is not getting any power at all,
only one of three things:
cord is fried/dead;
could be the outlet,
try something else in the same socket; or, the board in the ROUTER is dead.
Disconnect power cable WAIT FOR 20 sec and then reconnect it..Reset your router, ..To reset the router, the best way is to press and hold the reset button for 30 seconds, or to press the reset button for 60 seconds..and for first 20 sec hold the reset with the power cable connected and for the next 20 sec with out releasing the reset button disconnect the power cable and continue holding the restet button , and after 20 sec reconnect power back and then continue holding the reset for another 20 sec.. and then ncheck for the lights status ..

Try another power cord. Take it back to the store and have them exchange it or test it. They'll do that for free.
