If our driver was properly installed and but you’re having a hard time connecting to nearby networks, here are some possible solutions. Please try them and notify us of the result.
If you’re connecting the wifi adapter to an extension cable or USB hub, test without it.
If you’re testing with a front USB port, test with one at the back of the PC, or the opposite. If you’re testing with a USB3 port (blue color), test with a USB2 one (black color), or the opposite.
Try to delete all existing wifi connections in case they have wrong settings, then reboot and retry to connect. If you’re using Network Manager, you can open the connections dialog by running
nm-connection-editor in a terminal.
Open the connections dialog again (
nm-connection-editor), double click to edit the wifi connection and go to the
Wi-Fi tab. In the
Device box select your adapter, for example
wlx4401bb912885 (44:01:BB:91:28:85), and in the
Cloned MAC address box paste the MAC address, for example
44:01:BB:91:28:85. Save and reboot.
If possible, try to move your PC closer to the access point, to make sure that the problem isn’t related to the signal strength.
If possible, turn your Android or Apple mobile phone into a hotspot, place it near your PC and try to connect to that, instead of your usual access point. If it connects there, then we can focus at your router settings.
Some users have reported that enabling USB3 mode resolved their connectivity issues.
Some users have reported that disabling internal wifi adapters resolved their connectivity issues.
If your distribution is Debian 10 or older (not Ubuntu), then you might be affected by a bug in wpasupplicant. Try the workaround mentioned in Debian bug #879484, which is to add the following lines at the end of /etc/NetworkManager/NetworkManager.conf, and reboot:
In some cases it might help to revert the network adapter names from the new style (enp2s0, wlxa1b2c3d4e5f6) to the old style (eth0, wlan0), by running the following commands:
sudo -i mkdir -p /etc/default/grub.d echo 'GRUB_CMDLINE_LINUX_DEFAULT="splash quiet net.ifnames=0"' >/etc/default/grub.d/ifnames.cfg update-grub reboot
If none of the above solutions worked, it would help to test our adapter in a different PC and/or operating system.
