linksys wrt54g wireless not working
ok, the other day I temporarily disconnected the wiring and when i put it back to its original state, the wireless is no longer working. The dsl line is connect to my modem. the ethernet cable is connected behind my modem to the internet jack on my router. port one is occupied by my desktop and any other port(total of four) is used for my wireless laptop. I am pretty sure the wiring is correct, but there is no light indication on my modem for internet. The internet is working on my desktop and is only working for my laptop if i connect it to a port on the router directly. My laptop shows no signal from my router.

I checked the settings on http://192.168.1.1
and everything seems unchanged from before.



does anyone know the problem???

Not sure. You state that "the wireless is no longer working" and that "there is no light indication on my modem for internet" although you still get internet access. That seems to be two problems. The second one must be a very unusual LED failure. The first could be a failure of the router's wireless or loose antenna or some issue with your laptop's wireless.

yes u got it right, the internet light on the modem is not on but its still sending service to the router. I am online at this instant with my laptop but directly through the router port with ethernet only--still no signal for wireless though.

do you mean your laptop cannot see the wireless network?

and to correct myself, the internet indication light does work on my modem, but only when i connect the dsl modem directly to a computer and not to router. when i connect it to the router, everything still works but there is no light on "internet" and there is no wireless signal.

Disable encryption on the router and try to connect. If successful you can probably re-enable encryption and reconnect. If unsuccessful please show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

Login to the router, navigate to the wireless section, and set the encryption (or security) mode to 'none' or 'off' or 'disabled' or similar.
