When I got home today, I fired up my System76 laptop but I could not connect to the Internet. This was because my Wifi was down. a quick
Showed that the device was Hard Blocked. This means it is physically switched off. So I used the Fn+F11 key to turn it on again. No effect. I reset the BIOS to factory defaults, no effect. I booted into Ubuntu 12.04 (The newest official System76 supported Ubuntu Version) and tried Fn+F11, no effect. On a lark, I booted into OpenSUSE 31.1 Gnome, and the hard block was gone! I booted into my Tumbleweed and enabled the Wifi card from the Network Manager interface, and here I am. lol!
It seems to me that there is a kernel issue or a firmware issue. The kernel on Ubuntu 12.04 is 3.13, on OpenSUSE 13.1 it is 3.12. I am on 3.15. Does anyone have any idea what happened?
To make sure I have wifi access, I purchased a small USB wifi dongle last week (Edimax EW-7811Un 150M 11n). It seemed to work fine, and I thought I had a work around if the Intel wifi went down again.
But today, I had no wireless connectivity AGAIN. Yes, even the USB wireless adapter was “off.” Since I suspected the kernel again, I booted into Ubuntu, but still no luck. I combed the web, and my problem seems pretty unique. So I unloaded the Intel wireless drivers with the rmmod command
and VOILA! My USB wifi came right up and connected to my WAP!
At this point, I suspect that there is a hardware issue with the Intel card. Either that or a seriou sissue with he Intel drivers, which I do not think is very likely.
