arty, regarding your answers: 4b) WPA2-PSK -> If you remove encryption entirely, or adjust it to WPA-PSK/TKIP, WEP does it change anything? 4d) No QoS AFAIK -> So, in your router, what options do you have? 4f) I didn't enable any firewall on the router -> Does your router have an option to disable this? 4g) The problem has happened on several channels. -> Which ones specifically? Did you try them all? 5) At least 4 other WiFi devices do not have problems like this one. -> What devices/OSes specifically? 9) I have never tried that with previous releases. I do not have the option to try. -> One may test prior releases (live environment is fine) via http://releases.ubuntu.com/ . Saucy would be helpful as it tests the next oldest firmware version for your chipset. 10) Since I have already tried the latest 3.19-rc1 kernel, I don't see the point to test compat-wireless -> compat-wireless has the commits from linux-next in them, which is more advanced than 3.19-rc1 (linux-stable). Could you please advise to this? 13) I will try the ndiswrapper later. -> Please advise to this as it working rules out hardware failure. 16) I'm using linux-firmware 1.138. I haven't tried the previous version. Latest Intel firmware is from 3/25/2014, I assume it's already included in linux-firmware 1.138. -> It's not. I've adjusted the article to better inform on this.
