There is a kernel issue with 2.6.24-16-generic. Wireless seems to be broken for me. I have a PC with a Linksys WMP54G 2.0 PCI adapter (RaLink RT2500 802.11g ). I'm booting 2.6.22-14-generic and wireless runs smoothly, but when I switch to 2.6.24-16-generic wireless runs but with tons of errors, and as a result wireless speed drops.

It's also a problem with 2.6.24-17-generic

The rt2x00 drivers are still fairly experimental. I have an rt2500pci card and I found that installing the compat-wireless package from http://linuxwireless.org/en/users/Download restored performance to as good as it was in gutsy.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description doesn't yet have enough information.
Please include as attachments the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command 'uname -a' in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command 'dmesg > dmesg.log' and attach the resulting file 'dmesg.log' to this bug report.
3. Please run the command 'sudo lspci -vvnn > lspci-vvnn.log' and attach the resulting file 'lspci-vvnn.log' to this bug report.
For your reference, the full description of procedures for kernel-related bug reports is available at https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks in advance!

Please have a look at the workaround at #190515: [Hardy] Low bandwidth with rt2400 / rt2500 drivers. It helped me.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

The Intrepid Ibex 8.10 Beta release was most recently announced - http://www.ubuntu.com/testing/intrepid/beta . It contains the 2.6.27 Ubuntu kernel. It would be great if you could test and verify if this is still an issue. The status is being set to Incomplete until we receive further feedback. Thanks.

[Launchpad Janitor (janitor)]

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

It seems to me like this is working? (tested with ubuntu 9.04)

- works with suspend
- can connect to my own WPA2 network
- I can't see the other wireless networks, however. I'll take a look if there's a bug around for that.

[Leann Ogasawara (leannogasawara)]

@ekravche, since you are the original bug reporter, can you confirm this is resolved for you? Thanks.

[Jeremy Foshee (jeremyfoshee)]

Thank you for reporting this issue about a driver from the
linux-restricted-modules package. lrm-2.4.24 was shipped with Ubuntu
8.04 which reached end-of-life for desktop support on May 12th, 2011.

For that reason, this bug report is being closed at this time. I'm
marking it wontfix because what you describe is probably a valid issue,
but there are no plans to work on lrm 2.4.24 bugs further.

The issue may be resolved in a newer version. If not, aside from filing
a new bug report, another angle may be to file it directly with the
driver vendor.
