Can you please disable power save? For this, please make sure you have https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/iwlwifi-fixes.git/commit/?id=f8dfc607b2b460e8e8adfdfb3c5f5bba3a4ad01b or at least have the module parameter. I am wondering if the firmware is not sending frames because of power save toggling. I you could get more extensive logs from the AP it'd be great. Running tracing on the AP would let us know why it thinks we are not associated. > >> Laurentiu >> >> On Mon, Oct 20, 2014, at 11:23, Emmanuel Grumbach wrote: >>> On Mon, Oct 20, 2014 at 10:22 AM, Laurențiu Nicola >>> wrote: >>> > One thing that might be relevant is that, although there is a static >>> > DHCP lease configured (which works on Windows), the router/AP is giving >>> > the laptop a different IP address.
