I have the same issue with a Linksys WMP54G connecting to a WPA access point using rt61 driver on Ubuntu Feisty.
Installing the latest serialmonkey version of rt61 appears to eliminate the lock-up issue (i.e. it looks like they have this problem fixed). However (and this could well be a serialmonkey, not Ubuntu issue) it ONLY works if I first connect to the AP with NO security, then take the connection (and router) down and back up with WPA enabled. Connecting using WPA without first connecting in unsecure mode fails (iwlist scan can see it, but signal quality is 0/100, and dhcp fails). -- Ralink Wireless legacy drivers (rt2500 rt61 rt73 rt2570) USB/PCMCIA/PCI hangs PC https://bugs.launchpad.net/bugs/34902 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
