Wifi Issues on 18.04 (Kernel 4.18.0-15-generic)












0















I have been having a lot of trouble with the WIFI on my device. It has a RT 3290 wifi card which runs very poorly (frequently disconnecting, poor signal, super low speed, Bluetooth doesnt work) and I have to be literally on top of my router to connect to a network. In order to solve this I went ahead and bought a nano usb wifi adaptor which was a 148f:7601 Ralink chipset which although is recognised in lsusb , doesnt scan or show networks. Most answers have drivers etc which fail to load on my system due to kernel differences. Any help would be greatly appreciated.





The wireless info file can be seen here- https://github.com/abh1kudo/Ubuntu-Stuff/blob/master/wireless-info.txt



Thanks

  • Update- I have also added the dmesg immediately after plugging in the usb wifi dongle. Thanks for the help github.com/abh1kudo/Ubuntu-Stuff/blob/master/dmesg.txt

On our Ryzen mobo, we don’t have WIFI network under Kernel 4.19.x or Ubuntu 19.04 if Secure Boot is enabled. On custom kernel (unsigned), we must tweak Secure Boot on startup to keep it enabled: Booting in insecure mode.



Since last Grub updates: V1.93.13 & V 8.12



sudo mokutil  --disable-validation


Try disabling Secure Boot in BIOS to see if the device works or scans better. You may also go for the latest stable Kernel (4.20.10) or the latest long-term one (4.19.23). See if you get a better response.



Since Kernel 4.20.3, the WIFi network rarely fails and on Kernel 5.0 it works normally. Is connectivity enabled in Settings?



Check for the latest there:
https://www.kernel.org/
Get the PPA there:
https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D



~$ mokutil  --sb-state
SecureBoot enabled

dpkg --list | grep linux-image
