I did go through the guide described here to have the driver compiled and installed, unfortunately, this doesn’t do it for me. There is some hardware which is unable to get detected. You can first try this out, and if it resolves the issue make it permanent. Hello, I’ve bought a new laptop to replace an old one and unfortunately I forgot to check the driver availability before purchase. The solution was simple: Just modify linux boot parameter iommusoft. I will post the journalctl entries next time it crashes because I don't have them right now. The following solution was tested with Ubuntu 16.04 LTS Server on a Biostar Racing B350GT5 motherboard with AMD Ryzen 1700X processor. sometimes I'm connected with low band and other times high band. I have noticed that my Network Adapter switches between these two frequencies.
My router is configured for IPv4 (not IPv6), and supports channels in 2 GHz and 5 GHz band. anyway I don't think this is the problem.īut nothing was soft or hard blocked to start with so no differences. SET failed on device wlan0 Operation not supported.īut I keep getting this error. I spent almost a week trying to correct this problem, but in the end installing wicd and disabling NetworkManager fixed the problem. Upgrading to 16.10 did not fix the problem. I've tried to enable power management and then turn it off (even though it shows it is already turned off): sudo modprobe rtl8821ae sudo iwconfig wlan0 power offĮrror for wireless request "Set Power Management" (8B2C) : I had a similar problem with a Lenovo ideapad 300 which uses the same Realtek RTL8821AE WiFi.
