After using my entire day to try and fix my wireless internet connection, I have finally given up. It's probably do to my ineptitude when it comes to computers but I've tried several howto's and various suggestions and even reinstalled Ubuntu 8.10 to see if that'd fix the settings. No such luck.

I followed Kevdog's howto manual on setting up an unencrypted wireless connection (just to get a connection, the rest can wait) as well as some others that I've lost track of.

At this point it seems that my Linskys PCI card in my room desktop picks up a signal from my router but my Access Point, when checked, still says Not-Associated. Another "problem" that seems to be happening is that I cannot run a scan (sudo iwlist wlan0 scan or iwlist wlan0 scan).

I have a Linsky's WRT54G v8 router and the PCI adapter that came with it.

NOTE: after redoing a scan, it finally, for the first time in about 30 tries, worked and I'll have that posted.

I've tried several more times to reproduce the scan results but I continue to get 'no scan results' in response. I suppose I should also note, again, that I am particularly inept in dealing with computers.

What are the results of this?


lshw -C Network
And this?


lsmod | grep ndis

I haven't installed ndiswrapper (haven't needed to). The situation I'm in happened rather suddenly and unexpectedly. It's been working fine for the past 5 or 6 months until this morning.

Here's lshw -c network

have you tried inserting a static ip to wlan0? do bring down other interfaces in your machine which you are not using
