Description of problem: After running for a couple of minutes, wireless networking no longer works ( ie can't even ping boxes on lan using numeric ip's. Version-Release number of selected component (if applicable): Kernel 3.2.2-*, wireless is solid with previous kernel ( 3.2.1-3) How reproducible: Every time system boots Steps to Reproduce: 1.Boot system 2.Use network for several minutes 3.and wireless will no longer work. Actual results: cannot access network outside of localhost. All network utilities fail Expected results: The network should be functional Additional info: Using quad core i7 hp laptop, Intel 5100 wireless. Using PAE kernels Previous kernel works fine ( 3.2.1-3).
same happens on a thinkpad t410s with the latest non-pae kernel. previous (3.2.1-3.fc16.x86_64) is working properly. w-lan stops working after a couple of minutes. no unusual messages in dmesg. hardware(as shown by lspci): 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35)
Doing a rmmod iwlwifi ; modprobe iwlwifi brings networking back for a bit. I noticed the iwconfig shows a large number of Tx excession retries on loading a web page, 340 for a single LA Times page. Eventually the wireless fails again ( with no messages anywhere ). I seem to get slightly better behavior on 2.4 ghz than 5.0 ghz connects.
Just adding my +1 to this. I have a Lenovo T500 with an Intel Corporation Ultimate N WiFi Link 5300.
Maybe it's a problem in recent kernel: http://permalink.gmane.org/gmane.linux.kernel.wireless.general/84576 You can also try whether disabling N-mode helps: # rmmod iwlagn # modprobe iwlagn 11n_disable=1
rt2860 chipset, no wireless is not available at all. reverting back to 3.2.1-3 restores full functionality. kernel 3.2.2-1 PAE
I'm pretty sure most of these issues are fixed in the kernel in updates-testing, but it's hard to tell since everyone has different hardware and there are so few details.
3.2.3 cleaned up my Intel 5100 problems... Thanks Jerry
Yes 3.2.3 resolved my wireless issue with my rt2860 chipset.
I'm getting the same symptoms -- iwlwifi drops connection after about 30-60 seconds, nothing in dmesg -- but with a different and more recent kernel: 3.3.0-0.rc2.git4.1.fc17.x86_64
I'm also seeing this on F16 with a dell e6420 laptop using intel 6300AGN wireless. Seems like it may be semi-related to https://bugzilla.redhat.com/show_bug.cgi?id=772772
rmmod iwlwifi and modprobe iwlwifi 11n_disable=1 seems to resolve the issue, and the network begins to work again.
[mass update] kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository. Please retest with this update.
3.3.0-4 seems to work fine wrt suspend/wake. Jerry
