I recently installed Debian Buster on my PC. Since I don't have a internet cable long enough, I use AirLive WL-1600USB to connect to my router.On Windows it worked great, never slowing down without any reason.On Debian the connection is ok, but every 1-2 mins it slows down drastically for ~5 seconds.It doesn't bother me when working or internet browsing, but it is a huge problem while trying to play some games.  Example:PING google.com (172.217.20.206) 56(84) bytes of data.64 bytes from google.com (172.217.20.206): icmp_seq=1 ttl=56 time=18.4 ms64 bytes from google.com (172.217.20.206): icmp_seq=2 ttl=56 time=17.3 ms64 bytes from google.com (172.217.20.206): icmp_seq=3 ttl=56 time=28.8 ms-lag64 bytes from google.com (172.217.20.206): icmp_seq=4 ttl=56 time=90.8 ms64 bytes from google.com (172.217.20.206): icmp_seq=5 ttl=56 time=134 ms64 bytes from google.com (172.217.20.206): icmp_seq=6 ttl=56 time=211 ms64 bytes from google.com (172.217.20.206): icmp_seq=7 ttl=56 time=272 ms-returns back to normal64 bytes from google.com (172.217.20.206): icmp_seq=8 ttl=56 time=16.2 ms64 bytes from google.com (172.217.20.206): icmp_seq=9 ttl=56 time=47.1 ms64 bytes from google.com (172.217.20.206): icmp_seq=10 ttl=56 time=20.0 ms64 bytes from google.com (172.217.20.206): icmp_seq=11 ttl=56 time=29.6 ms64 bytes from google.com (172.217.20.206): icmp_seq=12 ttl=56 time=18.6 ms64 bytes from google.com (172.217.20.206): icmp_seq=13 ttl=56 time=18.9 ms64 bytes from google.com (172.217.20.206): icmp_seq=14 ttl=56 time=24.0 ms64 bytes from google.com (172.217.20.206): icmp_seq=15 ttl=56 time=25.6 ms^C--- google.com ping statistics ---15 packets transmitted, 15 received, 0% packet loss, time 14019msrtt min/avg/max/mdev = 16.229/64.984/272.654/77.174 msAlso (I think it's worth to note that) my card has screwed up USB IDs (1b75:8189 instead of 1b75:8187, fixed with the help of this post) and in the beginning it didn't play well with NetworkManager (fixed by this post). I'm using the rtl8187 driver.I've searched the web and found nothing. Is there a way to fix this?
My RTL8187L based card lags every minute or so
