Linux WiFi interface very slow
I'm running Ubuntu 18.04 with a Panda USB WiFi interface. Until a week ago (around the time I briefly put in the interface into Monitor mode), I was getting good connection speeds to my router. Since then, however, things have slowed down a lot (from 2-3 mbps to well below 1 mbps) and I'm getting high Tx excessive retries numbers from iwconfig - even after I turned Power Management off.
There's nothing wrong with my router or ISP connection - other wireless devices are getting great speeds.
Here's some data:
$ iwconfig
wlx9cefd5fe6a19 IEEE 802.11 ESSID:"Primus-2532"
Mode:Managed Frequency:2.462 GHz Access Point: 00:23:6A:78:25:34
Bit Rate=6.5 Mb/s Tx-Power=20 dBm
Retry short long limit:2 RTS thr:off Fragment thr:off
Power Management:off
Link Quality=47/70 Signal level=-63 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:259421 Invalid misc:7647 Missed beacon:0
Any ideas? Could I have messed something up while in Monitor mode?

As it turns out, purging and then reinstalling the wpasupplicant package fixed this problem.
