Indeed this still happens with NM in Precise. Usually, just restarting NM is enough, though, no need to reboot the whole machine.
I'm not sure if it's NM's fault or wpa_supplicant's fault. Every time I've experienced this it has been related to networks protected with wpa. ** Changed in: network-manager (Ubuntu) Status: Expired => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/943277 Title: NM cannot change wireless networks Status in “network-manager” package in Ubuntu: Confirmed Bug description: I have several wireless network available around me and I usually use one --- let us name it WNET A --- to update Ubuntu as it is the fastest and then there is another wireless network --- let us call it WNET B --- that I use to download other stuff as it is slow but has unlimited data. My problem is that I cannot now move from WNET A to WNET B; Ubuntu just won't connect to the other wireless network; it just keeps on sticking to WNET A. I have tried other non-Ubuntu laptops to connect to WNET A and also to WNET B and they can do it without any hiccups... help urgently requested please... Cheers!
