Why 5G adapter dub?

Friends, I ask you to help. Level - nard.
Bought a Wi-Fi adapter Archer T2U Plus. Everything seems fine, the router distributes 5G quietly, speedtest gives figures from 100-250. But! In games, for example, but even the Internet surfing is such that the speed drops sharply to 0. What do you think, what is it? Like the wood set up perfectly, technical support tp-link can not help in any way, saying that "we need to reset".
Then there may be those who will help?

There is a similar adapter, Archer T2UH, the problem is the same. Try this utility https://www.tp-link.com/ru/support/download/archer... Through it, set up a profile and connect to the router

The decision not to buy Tplink)
Nothing so categorical. Yes, they have found crap, but there are very decent pieces of iron.
It would be better to say: "do not buy Wi-Fi USB-whistles". - Enrico_Hilll commented on April 7th 20 at 15:43
