@Col777 

Screen shot of a laptop with built in Wireless, as you can see, no drops, no slow downs. This adapter can be used for gaming and voice without issue. 

Here is the same ping but using the TP Link T3U Plus, this is not possible to use for gaming or voice - 

Here are the driver details - 

I will test the driver link you have shared, thank you. 

Hello.

I have the same wifi adapter like @Col777 and i have the same problem, how is visible on the picture, i am using 2,4ghz, channel width 20Mhz, channel auto (i try make 1, 6 and without change). Wifi router Archer C6. On the first picuter is Wifi adapter Archer T3U Plus and on the other is cheap wifi from aliexpress (price 3$). Last windows update, i try reinstall drivers, but all withnout solution).

I will follow this thread to find out how to solve it.

I've tried the updated driver and the results were worse. The connection dropping completely, repeatedtly. I have been able to get a Powerline adapter working on certain sockets so my son has now moved into that room and is working well. 

I am highly dissappointed with this adapter, it has started to put me off the TP Link brand. I will be seeking to send it back for a refund if there is not a driver that works, £30 for this garbage. 

@Kathy_Z Hello is posible send me too the driver? Because i have the same problem. Thanks

@Kathy_Z - thanks I wil test. 

Hello.

Today i try to connect again the wifi, but now i give it to USB 2.0 and install normal driver which i download from TPlink website and what? The wifi work normally, so i try to give it to USB 3.0 and again high ping and the same problems like before. I try again to 2.0 and it work well. Before i try it too to  the USB 2.0 but it not work well like now (maybe windows update fix it? ). So @Col777 try to give the WIFI to USB 2.0. 

Thanks for helping me @Kathy_Z.

@Kathy_Z 

I too have same issue. Not able to use for inline classes or meetings.  10 seconds it will work and another 3  seconds no data transfer happens. And then it works for 10 seconds. And meeting screen freezes for 3 seconds every 10 seconds.

I have bought tplink tu3 WiFi adapter. And I have archer A6 ac1200 router.

Pls let me know the solution. I bought this mainly for online class for my kid unfortunately not able to use it. 

Checked other built-in adapter in laptop it's not an issue. Issue is with this t3u adapter. Kindly share if u have any drivers with fix.

Thank you

Hello.

I Think my problem was solved but not, i still have the same issue like before, i try another beta drivers but still same problem. So i use the cheap wifi from aliexpress. I recomended it to all of you, this tp lini get on the shelf. I dont have power to waste of time with this. 

So I ran into further issues with the beta driver, it would the connection completely about once a day. This would require a restart or a run of the troubleshooting wizard to recover. 

I am done trying to get this working, it is being sent back to Amazon today. 

Thanks a lot to all the support folks trying to help, appreciate it. However, please advise your hardware folks to stop making garbage NICs/Drivers.
