I've had this issue after upgrading to 9.10 as well. Automatic DHCP fails, but if I set a static IP address then it works. (It only greys out the option until you have all the proper info filled in, eg. netmask and gateway.)
Only tried this at home; if dynamic DHCP fails everywhere I go then this effectively cripples wireless away from home. -- After upgrade to 9.10 Network Manager failed to connect https://bugs.launchpad.net/bugs/379219 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
