[Kernel-packages] [Bug 1848921] Re: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010]
I have a Lenovo Yoga S730 (marketed as Lenovo ideapad 730s in the US, mine is European) with the 9260 card and I can confirm that the same issue affects me. The wifi works fine in Windows 10. The only way I've managed to resolve the issue is by adding 11n_disable=1, but this caps my speed to 54mb which is too much of a compromise. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1848921 Title: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010] Status in linux package in Ubuntu: Confirmed Bug description: Ubuntu 19.10 Kernel 5.3.0-18-generic Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.
