I thought my lynksis wcf11 didnt work, because i would plug it in and the light would keep flahing, it would only connect to the router once in a blue moon.
you may think this sounds quacky, but it works: i find that if you hold the wireless card with your fingers when youre connecting or transferring data, it connects great and transfers data lightning fast. apparently the human body's electrical feild works like an antenna. Ive tested this multiple times, and have found that i get a connection in under 2 seconds if i hold the card with my fingers, and it wont connect most of the times unless i hold it. I dont know why this happens, maybe the internal antenna in my card isnt functioning or theres some other kind of interference going on here. i just discorvered this today and my trusty sl-5000 is back on the net.
