So I replaced my Intel 8260 with an Intel 9260 in my Librem 15v3 and the difference was astounding.
- Wireless KIllswitch works again.
- Laptop appears to correctly enable the 9260 even during a cold boot (8260 required a warm reboot cycle to work)
- 8260 was having problems for me in kernel 5.1 that required me to turn wifi off and back on again to bring it back online occasionally. 9260 thus far does not appear to have this issue.
All in all, I’d say if you are looking for a better wireless module for your Librem 13 or 15 and you don’t mind a firmware blob, the Intel 9260 makes for an excellent choice. Thanks for sharing this info with me!
