Hello everyone. I've been using my D-Link DWA-160 network adapter for around two years without any issue for a couple of years. Some weeks ago however, it started misbehaving. After I use it as usual for a seemingly random amount of time (but see below), spanning from a few minutes to several hours, I suddenly get disconnected from wifi. After that, if I try to connect again with nmcli my computer freezes and I can only force it off. However, if I unplug the adapter, plug it in again and then reconnect with nmcli everything works fine - until I get disconnected again. At first I didn't bother to even look for a solution, since this happened only once in a few days. However, now it happens several times a day, and most often when I reach high download speeds. Anything around 2 MiB/s for more than a handful of seconds seems to be a granted trigger. I couldn't find any useful information online and I know nothing about wifi hardware or software. Can anyone help troubleshooting this?
