You need to provide more details, i.e. network card model, some relevant logs, configuration, etc.– Andrejs CainikovsMay 22, 2012 at 19:58

1Try to remove your wireless connection, Ubuntu will recreate it. You can do that in Network Indicator.– Basharat SialviMay 22, 2012 at 20:24

This happens to me whenever I have a weak wireless connection, and is highly annoying. If I leave my machine on overnight and return, I may have 50 popup windows asking me for the password. Model is zareason strata pro– cboettigJun 20, 2012 at 21:55

Is your network encrypted? That will happen if you're on hardware that (or its driver) doesn't support your encryption protocol.– KyleSep 18, 2012 at 18:41

If you are able to change your wireless router's settings, examine the Channel Width and Mode. I find that some network cards, particularly those with older chipsets, have trouble making and maintaining connections to routers with a Channel Width of 40MHz (or a router set to auto, which can adjust itself among multiple widths). For me, the solution was to change Channel Width to 20MHz.
Open Network Connections
Got to the «Wireless» tab and choose your net. Enter the BSSID. It is something like «00:11:22:33:44:55»
Finally, check the «Wireless Security» tab. The most common security protocol is WEP (Hex or ASCII), but you can try other options.
