I installed the T4U V3 dongle wifi adapter (5GHz connection) and it worked well for a while. Then I noticed the wifi connection quality (monitored via taskmanager) dropped suddenly when certain applications were working. The first application I noticed was WifiInfoView, a free networking check tool. Whenever it was open the signal quality oscillates, like every few seconds the connection would drop to 0kbs for half a second and later it would catch on.

Later, I saw the same pattern emerging on Microsoft Teams, a on-line meeting software that I use for work. Even though I get a "strong" signal with it, sudden drops make webconferencing not possible. Anyone has a fix for that?
