I've been experiencing wireless issues with my laptop that runs an Intel Ultimate 6300-N card with the iwlwifi drivers for a couple of years now. I'd seen numerous bug reports on many different distributions incl. bugzilla for kernel.org reporting similar issues, but not always exactly the same type of issue as mine and was always hopeful that a fix would be forthcoming. The issue: I experience occasional packet loss and extremely poor latency when doing any activity over my wireless network. I experience this no matter which AP I am connected to, and I have tried various iwlwifi module options (11n_disable=1 or 2) and these can improve the situation but are not a solution. I've attached a few log files that help detail my setup, and show some of the errors found in dmesg during transfers and also a log of latency results of a ping to a system on my local network (e.g. I'd expect replies around the 1-2ms mark, not up to 12000ms like I occasionally have) I run ArchLinux, and have done for a couple of years, and I'm almost certain I've had wireless issues since install around when the kernel 3.0 series began. Logfiles attached: ping.log -- shows the extremely poor latencies I get when doing transfers over wireless lsmod.log -- lsmod of drivers running dmesg.out.log -- errors seen in dmesg during the wireless transfers iwlwifi.firmware.1.log -- ls of /lib/firmware/ directory to show version of firmware iwlwifi.firmware.2.md5s.log -- md5s of said firmware lshw.log -- sudo lshw to detail hardware date.log -- just the date this was all done (to ascertain approximate package versions if needed due to rolling nature of ArchLinux) uname.log -- current kernel version. modinfo.iwlwifi.log -- iwlwifi info modinfo.iwldvm.log -- iwldvm info iwconfig.out -- iwconfig output showing large TX excessive retries and invalid misc I'm disappointed in how long this card has had issues under Linux, and it reflects poorly on Intel products and their driver support in Linux. As it is, this product is faulty when used under linux, even though it is stated as being supported by Intel. I would really like to obtain a fix for this. If I can assist in any way (running custom firmware/kernels/drivers, providing more info, perhaps step-by-step explanations for debugging, or even potentially providing SSH access to a liveCD instance running on this system) then please let me know. If there's an official intel wireless bugzilla somewhere, please point me at it if I need to log this there. Regards. Michael
