Nicolas, Unfortunately your question don't have a simple answer. Moreover there isn't a way do this well in a bug report. Perhaps in UbuntuStudio+1 will make some line of texts for explain differences between these two kernels. However can I close this bug?

[Bug 436043] Re: Ralink wifi doesn't work with latest -rt kernel
Hi Alessio, I just tried the latest Lucid updates (with kernel 2.6.31-10-rt) and the same problem is present. The wireless card is detected but NetworkManager shows all networks with full signal strength, successfully connects but then I have no internet connectivity. The problem was solved with kernel 2.6.32-16-generic by installing the linux-backports-modules-wireless package, but no such package is available for -rt. -- Ralink wifi doesn't work with latest -rt kernel https://bugs.launchpad.net/bugs/436043 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Nicolas, Sorry but we can't provide linux-rt based on 2.6.32 for Lucid. So the bug will not fixed soon. In any case I would want suggest you, if you still need a low latency environment, to use my -lowlatency kernel available on my PPA.

Alessio, I managed to get wireless to work with -lowlatency by compiling installing the rt2870sta module from Ralink 2.3 driver sources (and enabling its wpa_supplicant related options).

[Bug 436043] Re: Ralink wifi doesn't work with latest -rt kernel
I did some additional experiments with rt2* modules. I tried compiling and installing the drivers from ralinktech.com (ignoring the errors and blacklisting rt2800usb, as indicated on several forum threads I found). They work perfectly with the -generic kernel, and seem to work better than the stock modules with -rt: NetworkManager shows correct network signal strengths and remote hosts are finally reachable. However, when using the -rt kernel, after a few minutes the system becomes very sluggish (or, to be more precise, mouse and keyboard input are sluggish, as the system overall performance seem to be normal), with no additional visible kernel messages and nothing hogging system resources (at least to the extent visible in top). Then I tried getting the linux-backports-modules source package and compiled it against 2.6.31-9-rt. It worked, but gave the exact same results as the ralink driver (I guess linux-backports-modules contains the latest ralink drivers). I also tried using Wicd instead of NetworkManager, with the same results. In a few days I will try using the ralink driver with its .dat configuration file. I have one question, though. Are there any options I could pass to the rt2xxx modules to make them more verbose ? I had a quick look at the driver source, but couldn't find any. -- Ralink wifi doesn't work with latest -rt kernel https://bugs.launchpad.net/bugs/436043 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 436043] Re: Ralink wifi doesn't work with latest -rt kernel
Okay, I think there is something I've missed since the beginning with this bug. I just did a full reinstall of Karmic (switching from fakeraid to lvm) and when I first booted on 2.6.31-14-generic... wireless network didn't work, with the exact same symptoms as those I've described here: requesting firmware message, visible networks but with always full signal strength bars, etc. The problem was solved by installing linux-backports-modules-karmic (which depends on linux-backports-modules-2.6.31-14-generic). I recall having installed this package on my previous setup (don't remember the reason, though). I also reinstalled linux-rt, and the problem is still present, which is not much of a surprise. And there's no linux-backports-modules package for -rt. Now, I don't know how to act. Should we call this bug no backported modules for linux-rt, or my ralink usb wireless card does not work without backported modules ? -- Ralink wifi doesn't work with latest -rt kernel https://bugs.launchpad.net/bugs/436043 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
