Lately, both my laptop and my iPhone have been stuck on 169 IP addresses when trying to connect to my LAN wirelessly. Both devices connect just fine to other networks, remembering my parents' network four months after they last connected to it.

It gets worse, though: I just tried connecting the laptop to the router by ethernet, and I'm having the same problem. Connecting the modem directly to the laptop works fine: Good IP address, websites load. Strangely, the desktop I'm using now is also connected to the router by ethernet cable, and works fine.

The problem would appear to lie with the router, but my Google searches are turning up nothing useful. The router in question is a Linksys Wireless-B. Any particular settings I should be looking at?

Thanks!

Have you tried powercycling the router?

If that does not work. At the back of the router there is a reset button that should get router back functioning.

Btw what is the IP address that you are getting with the PC that you are on right now? It should be on the 192.168.1.1xx range.

Yep, definitely power cycled the router (occasionally it will throw a snit where I have to do it, so it's one of the first things I try if I suddenly lose connection). I can certainly hit the pen switch and restore the manufacturer's defaults, but want to save that for a last resort. I had to do that once, after I stupidly turned off the router's DHCP server and had no idea of how to restore it when I couldn't get in.

My desktop is pulling an IP address of 192.168.1.131 which, while a little high, is a perfectly normal 192 address for the router to assign. Plug the laptop in, and no dice: 169. Again, it works on other networks (both wireless, and by ethernet cable) just fine. Oh well, I may just have to take a screen shot of my port forwarding, and reset the router. I'm just hoping to find a less drastic solution...

MAC address filtering??

I doubt that your PC is the problem. It sounds to me like a DHCP problem with your router. Or perhaps it badly needs its firmware flashed or updated.

I checked Mac address filtering, and I don't have anything set there.

My thoughts exactly.

Or perhaps it badly needs its firmware flashed or updated.

Ah, yes. I'll take a look at that...
