When I transfer large files (few Gb for example) wifi connection can be broken or freezing. If this happened - I can't connect to AP until reboot the system. What additional information would need to provide?
Hi, This probably is a duplicate of another bug that we've already known. http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2037 The fix for that problem is not in 2.6.32. I noticed that you also tried 2.6.34rc5. Did you see the same problem with that kernel? If you still see this problem, please compile the driver with debug info, load driver with option "debug=0x43fff" and send us debug logs while reproducing this problem. Thanks, Shanyu
This issue not reproduced with 802.11g connections, only with 802.11n. But by another bug I can't connect in 802.11n-mode with latest version of driver, and can't provide debug info until this bug https://bugzilla.kernel.org/show_bug.cgi?id=15892 is fixed.
This is a bug for 2.6.32 stable kernel. The kernel incorrectly recognize all 5150 devices to be AGN but actually the user has an ABG device. Please refer to the other bug for detail: https://bugzilla.kernel.org/show_bug.cgi?id=15892 Shanyu
Can you identify which patch corrects the identification of this device?
I tried, but no success.
The patch is: commit 7a034ec5ece275f12826fda1e9f6cbd29165baef Author: Wey-Yi Guy <wey-yi.w.guy@intel.com> Date: Fri Nov 13 12:03:31 2009 -0800 iwlwifi: update supported PCI_ID list for 5xx0 series Update the PCI_ID list for 5xx0 series. Remove all the PCI_IDs which never made into production or not longer in production. Also make sure the supported bands(a/b/g/n) match specified PCI_IDs Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> It does not apply to 2.6.32. Since 2.6.34 does not have the identification issue, can you try that kernel to see if you are still running into this broken connection issue?
Created attachment 26628 [details] patch on top of 2.6.32.15 I back-ported the patch Reneitte pointed out. It should cleanly apply to 2.6.32.15. Can you please give it a try to see if your device is correctly recognised as ABG instead of AGN?

Yes, device correctly recognised. > Since 2.6.34 does not have the identification issue, can you try that kernel > to see if you are still running into this broken connection issue? I check this bug with 2.6.35rc1 kernel. It's looks like in g-mode this issue not present. Because now device recognized like ABG instead of AGN, n-mode not available. In g-mode I can't reproduce connection freezing when transferring large files. I think this bug can be closed.
The patch has been submitted to 2.6.32 stable kernel.
