There is a problematic AP, and every time I connect to this AP, the connection only works for a couple of hours and then it stops working until I disable and re-enable the wireless adapter. Here is the dmesg log: https://pastebin.com/CnbBSNg3 There is a firmware crash. Then the driver fails to read the firmware dump. Note that I've only seen the problem with this specific AP and not others. Is there any way I can figure out what exactly is it with this AP that triggers the problem? Thanks & best regards, Tim ps.
