On resume, laptops don't do a rescan of wireless networks

[Kyle Mathews]

I run a laptop as my main computer as I'm often moving around to different places during the day and connecting to different networks each time. The network-manager has a really annoying default. When I come out of sleep, the laptop tries to connect to last used wi-fi network -- which granted makes sense most of the time. The problem is when I move, that old network isn't accessible anymore and oftentimes I'll wait 30-45 seconds for network-manager to figure out that the old network isn't around anymore, then another 15-20 seconds for it to select and connect to a new network.

What I'd like is that when first coming out of sleep, for the network manager to do a wifi scan to see if the old network is still around, and than connect -- or at least add a gui option to kill the fruitless attempt to connect and move on.

It's quite annoying when I open my laptop briefly to look at something to have to wait one minute plus to connect to the internet.

I run into this many times a day; it's painful.

For me, with intel wireless, completion of this command will cause NetworkManger to react:
 sudo iwlist scan <wireless network device>

Should bug 264683 also be marked as duplicate of this bug?

Thank you for bringing this bug to our attention. Unfortunately a paper cut should be a small usability issue that affects many people and is quick and easy to fix. I'm afraid this bug can't be addressed as part of this project.

This is a software specific issue, and affects only the wireless , laptop users. Though their numbers are large , this does not qualify as a papercut.
A paper cut is a minor usability annoyance that an average user would encounter on his/her first day of using a new installation of Ubuntu 9.10.

For further info about papercuts criteria , pls read > https://wiki.ubuntu.com/PaperCut

Don't worry though, This bug has been marked as "invalid" ONLY in the papercuts project.
