Hi
I have a problem with wifi on my laptop. It has 50-60% near the home wifi router, no signal if you are in six metres away. wifi works in other OS and has great signal.

Hi backtrack,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? 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 from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 508882

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.

This bug also affects me. I have just installed final release version of Ubuntu 10.04 and am experiencing a problem with a weak wireless signal. All works fine with other operating systems but signal is 30% with laptop next to router in Ubuntu, which will not connect. I have a Realtek RTL8192E wireless card. Has there been any activity/solutions to this problem?

Hi, here I'm having problem with maverick kernel and this network card

Connection is lost every few minutes

I'm now testing it with

modprobe rt61pci nohwcrypt=1

Will see if it works better ...
