Hello.

Bought 2 days ago new one TP-Link Archer T2U [AC600], on box is said - "150Mbp/s(2.4GHz)" so it's ok, my internet is a 50mb/s but a router must be in different room than my PC.
In home only I'm using hardly internet, other guy is a little bit older than me and he don't use internet so much. But the performance is very low, just now I have 3 of 5 bars, but mostly it's 4 (3-4m from router, only soft wall between), when I try to connect with Smite game, I can't connect to matchmaking, that will be happened after +/- 30 seconds and I have big pings like 500 but sometimes lower about 100 what is too much anyway. CS:GO have same problems, TIBIA aswell, I was thinking for moment maybe it's something wrong with my PC, scanned it 2 times, but there is still nothing, reinstalled 2 times drivers (original disc from box), but I asked my mate to borrow me again his adapter and everything works very fine on it. So the problem is Archer. I have some experience with another TP-Link and this PC (before I refreshed hardware) and there was problem with that aswell.

Before I was using different adapter from another company, with same price and performance, which was like a prescription to that what I need. I found this one in Argos, they haven't same like before I had, so I got Archer, just other name. But pings was permanent very low, just no weird lags like now. I don't use internet to anything else, I'm only playing games and some movies etc.

I hope I don't have to give it back to shop and never look on TP-Link name.
