Correct, you want to keep roaming enabled, and that's not possible (obviously) when locking to a specific access point. There a few things that will make this better: 1) Apply the following patch to your wpa_supplicant, which will make the problem much better but http://pkgs.fedoraproject.org/cgit/wpa_supplicant.git/tree/rh837402-less-aggressive-roaming.patch 2) Apply the following commit to your NetworkManager packages, which requests that the supplicant scan for roaming a little less often: http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=dd9cf657ef1f9d5909dad2eb697098715325fecf 3) Wait for some upstream changes to the supplicant, which will include *some* form of the above patch, as well as one I posted upstream to request the supplicant not to roam as a result of an information-only scan that NetworkManager periodically does. Obviously all these fixes depend on the kernel driver also reporting the signal strength correctly...
