Wireless router acting strange--any suggestions?

I've had the strangest things happen with my WRT54G router recently and cant' figure out what's going on!

First, my laptop's wireless adapter refused to turn on even though the device manager said it was fine. Then my girlfriend's laptop lost connectivity through her wireless connection as well.

I connected directly to my modem via CAT5 cable and was able to dial in via PPPoE.

My wireless adapter turned on again, but I suddenly couldn't connect to the wireless router. After I gave the router a hard restart and reconfigured it I can connect to it via my computer, but I can't receive any internet connectivity through it.

The funny thing is, I can connect to the internet via my router with CAT5 cable, just not through the wireless connection, even though I receive a wireless IP address from the router.

Any ideas? TIA!

 

Im going to say that most likely your wireless router's connection to the modem isn't working at the moment.

You should first make sure that is configured. Even when a wireless router isnt connected to a broadband connection, you can still connect to the wireless on the wireless router, similar to how one would connect via ethernet cables on a router.

 

But at the moment I'm connecting to the internet via my router! I just have to use a CAT5 cable because I can't do it via the wireless.

 

Please report back on success or failure for each of these using your wireless connection.

Ping router.
Ping gateway.
Ping DSL provider's DNS server(s).
Ping Yahoo's IP address (216.109.112.135).
Ping www.yahoo.com.

 

WackyT, I get Destination Host Unreachable across the board. When I plug the CAT5 cable into my router I get 0% loss across the board.

zx10guy, when I ping the router, yeah, I get destination host unreachable. The IP address it gives me is 192.168.1.100, which seems to be what the DHCP server is set to give out--three addresses starting at 192.168.1.100. I guess there's something I'm not understanding about that. Do I need to turn DHCP off?

 

When you reset the router did you clone your mac address and put your connection info into the router? This part is required for the wan side to make the connection to your ISP. While connected to the router check your ISP connections. It should tell you if your connected or not.

You need DHCP ON unless your ISP gave you a static IP. Most do not. Most just register the MAC address of the pc used to setup the account. The reason it's a good idea to clone your mac address.

 

I don't have the MAC turned on--I'm in a no-wireless neighborhood in backwoods japan so don't need security! Haven't used MAC since I've set up my wireless network, which worked for many months. I did use a WEP key, but have disabled it to try to get my network running again...

 

Yes, I have another computer here, but it's a Japanese Windows ME computer. I can probably manage it with instructions. You mind giving it a try? I'll be back on in 12 hours or so.
