Wifi on Linux is still puzzlingly terrible. I bought a new card (TP-Link AC600 Dual Band USB Adapter w/ External Antenna) because it was supposed to have Linux support, but the manufacturer-provided drivers were only for Linux Kernels up to ~3.1 and I’m on 4.4.
> cat /proc/version Linux version 4.4.0-38-generic (buildd@lgw01-58) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.2) ) #57-Ubuntu SMP Tue Sep 6 15:42:33 UTC 2016
OK, time to google. I found many references to this advice circa September 2015, which advocates use of a modified driver from github. After reboot I got a kernel panic, so I looked through the pull requests and found one critical fix that hadn’t been accepted upstream yet. Installed this driver instead, then did the following:
# Got the USB card recognized by loading the driver module. sudo modprobe mt7610u_sta # Bring up the interface. sudo ifconfig ra0 up # Modify the network manager config to set managed=true, forcing network manager # to manage my silly network card. sudo vim /etc/NetworkManager/NetworkManager.conf # Reload the network manager. sudo service network-manager restart
Card works now.
Since I didn’t use DKMS, if the kernel gets upgraded I’ll have to reinstall this driver.
Looks like the most active version of this driver is not the one I used, but this one: https://github.com/chenhaiq/mt7610u_wifi_sta_v3002_dpo_20130916. If I had to start over I guess I might use that branch instead, seems like a bunch of fixes are applied on it.
