Bug Description

Wireless network fails to connect after upgrade from Lucid to Maverick.
This appears similar to
#594866 [Maverick][2.6.35] RT2860 (ralink) support seems to be broken (it fails to connect to secured wireless networks)
however,I have tried setting WAP to be completely open (has no security) and the problem persists.

The network interface is:

There is a thread on the linux-wireless list that sounds like it might fix this problem, see http://www.spinics.net/lists/linux-wireless/msg53115.html and especially http://www.spinics.net/lists/linux-wireless/msg53204.html ("The patch lets me use wifi"). I have not yet actually tested this patch though (as I do not remember how to conveniently and sanely build just the affected module with the patch applied).

Bob Ballantyne, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
