iwl3945 does not handle weaker signals as well as ndiswrapper does

[Eric Appleman]

I have found that iwl3945 will not offer weak signals for connection whereas ndiswrapper with the appropriate 3945ABG driver will offer signals as weak as 1% in Wicd and Network Manager.

I figure that this isn't a proper behavior since the signals that ndiswrapper picks up are already 10% weaker than those of iwl3945.

Hi Eric,

If you could also please 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.
