I have this problem too, or a similar one. Oneiric 11.10. The Wifi here in my university has different SSIDs --- all normally with very similar strengths. I have sometime connected to all of them, but having them different "privileges".
For example, I have a WPA2 "local" SSID with full access to the network, and a WPA2 "global" SSID working in almost all Spanish Universities with quite reduced access (it's thought for guests, and it's the same SSID all around, so when I am in another university, I use it). There seems no way to say to NM that I want the local one, if in range, even if the global could be stronger. If a disconnect occur, or if an auto-suspend occurs, NM reconnects to one of them in almost arbitrary way. I understand the trend to keep the interfaces simple, but a way of marking "personal priority" should be provided. And by the way, a "never ever again connect to that network automatically " should be there, too: there are a lot of very insecure free hotspot around and if you make the error of connecting one time, then it's very convoluted to mark them off-limits (see also https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/891678) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/111502 Title: network-manager unreliable with multiple APs To manage notifications about this bug go to: https://bugs.launchpad.net/network-manager/+bug/111502/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
