I have found this same issue with numerous ralink-based cards on numerous different people's laptops now, in the final release of edgy. It seems like there is no way, with the new System-Administration- Networking GUI, to tell the card to scan for networks and provide a list.
I am not sure whether this is a bug with ralink chipsets in particular, or whether it's a bug in the GUI that affects all network cards (I don't have any non-ralink cards to test this with). I can also confirm that if I enter the ESSID manually I can connect, and that if I run 'sudo dhclient ra0' from a terminal it can find dhcp networks and connect to them fine. -- RaLink rt2500 wireless card not seeing networks in edgy https://launchpad.net/bugs/64334 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
