Re: Pls help: Netgear WN511TA_pcmcia
I'm going to suggest something silly (as a new user myself) but in Karmic Koala, I just clicked on the cell tower icon in the top right panel and was immediately able to see my network SSID, and just clicked on it to start it up. It connected flawlessly on the two ancient laptops in my signature, and the "Link" light on my ancient Netgear card came on instantly. Everything has worked ever since from start-up.
You seem to have some experience with Ubuntu already (certainly more than me) so maybe this is ridiculous, and maybe you've already done all that, but maybe not (I don't know if 9.04 has equivalent wireless functionality 9.10) I had no need of ndiswrapper or anything else, other than the basic installation. In fact, everything worked out of the box from the Live CD.
Perhaps you could try the Live CD of Karmic Koala and see how your card works with that? It might help figure things out, at least. I'm guessing that if it works with the Karmic Koala Live CD that it'll just be a matter of figuring out how to get your installation updated with the necessary stuff.
Best of luck, and don't pull your hair out!
