My laptop's Netgear WG511T wireless card, which in the past has worked flawlessly in Ubuntu and Fedora, has suddenly stopped working. And I don't know why. What are some things I can do as far as the command line or GUI tools that I can use to get it working, or find out why it is not working?

How did you install the driver for it? Was it detected automatically or did you use ndiswrapper?

As stated some more information would be helpful. What are the results of the following commands?

lshw -C network
iwconfig

If you used ndiswrapper, run this and search for your wireless card to see what driver is being used:

lshw -C Network

The result should be something like this:

*-network
description: Wireless interface
product: BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller
vendor: Broadcom Corporation
physical id: 6
bus info: pci@0000:03:06.0

clock: 33MHz
capabilities: bus_master ethernet physical wireless
configuration: broadcast=yes driver=ndiswrapper+usrmaxg driverversion=1.5

That's my wireless card, I used ndiswrapper to install it. It should say ndiswrapper +[your driver]

If that's not the result, blacklist the driver thats there and run this:

sudo update-initramfs -k all -u

Then reboot.

I was not using ndiswrapper, as the driver for this wireless card is built-in, so it works out of the box usually. Anyways, here's the output for those two commands:

I cannot say that this looks like a good result:

I will attempt to run a liveCD and see if that works. Will be using puppy linux because I don't think this laptop's hardware (700mhz pentium3 with 256mb of RAM) is strong enough to handle Ubuntu liveCD.

The puppy liveCD didn't work. I'm guessing that the wireless card has outlived itself.

you could try setting up a static ip for your wlan0 interface as it doesnt seem to be getting an ip

How do I do that?

Tried that just now, and it didn't work. I'm guessing the wireless card probably failed.
