Hi,
I have tried a number of 2.6.30, 2.6.31 and 2.6.32rc6 kernels trying to get my D-link DWA-140 N-usb adapter to connect to my AP (DIR 655 N-router). This adapter works fine in Mepis 8 (kernel 2.6.27-35) using a homemade rt2870sta .deb from the Ralinktech 2.1.2 source package.

None of the kernels mentioned did work out for my wireless adapter, until I found and used the 2.6.30-7.dmz.1-liquorix-686 kernel. All of the other kernels had in-kernel modules rt2800usb, rt2x00usb and rt2x00lib "onboard". However, they did NOT work at all with my wireless N- usb adapter.
The 2.6.30-7 liquorix kernel does not have these 3 rt modules onboard (added: well, technically they are there, but the modules are not enabled) and after blacklisting the rt3070sta I made another rt2870sta .deb for the liquorix kernel, rebooted and I was online again.

Thanks for that 2.6.30-7 kernel!

Now, two things; one question and one negative observation:

Question: Are the newest liquorix kernels (f.i. 2.6.32-rc7) using the rt2800usb, rt2x00usb and rt2x00lib in-kernel modules, or are they configured without them (like the 2.6.30-7) ?

One negative thing about the 2.6.30-7 kernel: Some sites with flash content (f.i. www.speedtest.net, when having finished doing a speedtest) are showing momentary visual distortions; much like short screen distortions that sometimes occur on digital tv).
It didn't make any difference whether the nv or nvidia 190..42 driver is used (Graphics card is Nforce 7600 Go in a HP9000 laptop).

All my kernels have whatever modules available enabled for wireless. RaLink must have been recently included in 2.6.31 to cause problems with the source you're using.


And, 2.6.30 may have issues with any media due to using CFS. This mainline CPU scheduler doesn't have reliable latency deadlines due to it's interactivity estimator algorithm.

I'm not updating 2.6.30 anymore, there's not much to improve besides security - but the updates you can receive are through the newer kernel versions.
