I installed ubuntu for the first time (first time ever using linux) i used my friends wireless card to update but when i got home and put in my wireless card it asks me for a password i put in my password, it tries to connect for 20-40 seconds and then it asks again for password.. and every other device i have has had no problem connecting with the same password and network?

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

    Try to remove your wireless connection, Ubuntu will recreate it. You can do that in Network Indicator. May 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

  • Is your network encrypted? That will happen if you're on hardware that (or its driver) doesn't support your encryption protocol.

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.
