AC600 T2U Plus is disconnecting in Windows 10 (freezes/lags in game)
AC600 T2U Plus is disconnecting in Windows 10 (freezes/lags in game)

I had huge lags/freezes in Overwatch game.
Then I realised that T2U Plus USB card is getting disconnecting.
So I used USB Tathering from my phone and I had 0 lags.
That means It's T2U Plus issue.
What I tried already:
- disablind driver updates in Win10 (preventing drivers overriding)
- tested official drivers and drivers brought by Windows update
- setting Power plan in Windows for maximum performance
- disabling selective suspend for USB ports / USB devices / T2U Plus card
- testing T2U Plus in different USB ports (USB2.0 and USB 3.0)
- different wireless modes a/n/ac, ac, b/g/n.
- disabling IPv6
What I didn't try yet:
- testing T2U Plus in different PC/Laptop
- testing with different OS / different Win 10 version
- use usb extension cable (USB port overheating theory)
Adapter model: AC600 Archer T2U Plus V1
MOBO: MSI B450M MORTAR MAX
CPU: AMD Ryzen 5 3600
OS: Windows 10 Pro (v2004)
Please, help

Good day.
Thank you very much for your kind reply.
Could you please help me check the following information:
- When using my Phone with USB Tathering, Is the phone on mobile data or Wi-Fi network of the main router?
- May I know the model number of your main router, and is it dual-band router, or just single 2.4ghz?
- If you did not play online games, would there be any drops out on T2U plus?
Please also try to update the following beta driver to have a look:
Thank you very much!

Hello, we are sorry to hear that you have trouble with the adapter. We will try our best to help you identify and solve the issue.
Please help us get the following information:
1. How often does this issue happen? How far away from the router to the computer?
2. Which band has the unstable connection? Both 2.4GHz and 5GHz band Wi-Fi?
3. Do you have a stable connection from router on other Wi-Fi devices ?
If so, please change the Wi-Fi channel of the main router. Please change 2.4GHz channel to be 1 or 6 or 11; the 5GHz channel to be 36 or 40 or 44 and save them.
Or you can download WI-FI analyzer on your phone to test the empty Wi-Fi channel around and change the channel to be empty one for both bands.
Then please check if the same issue happens again.
4. When the connection lost, was the Wi-Fi still connected but no internet / completely disconnected/got some Errors message? What is the Error message? 5. If WI-FI connected but no internet, what is the IP address and default gateway? https://www.tp-link.com/support/faq/838/
6. How to recover the connection? Automatically or reboot the PC?
7. What is the model number of your Wi-Fi router?
8. Please send us a photo of the driver version and computer system information by referring to this FAQ : https://www.tp-link.com/support/faq/2722/
BTW, may I know when and where you bought the adapter? When did the issue start?
Thank you for your precious time.
Wish you a nice day.

1. Lets say it is happening every 10-20s. I live in Hotel. Router must be somewhere near me. Signal is great. Like I said before - I don't have any lags and any problems while using my phone's USB Tathering.
2. I'm unable to change it. All options that I have in Advanced settings:
AdaptivityPara - 0,
EnableAdaptivity - Auto,
HLDiffForAdaptivity - 7,
L2HForAdaptivity - Auto,
QoS Support - True,
Roaming Aggressiveness - Disable,
VHT 2.4G IOT - Enable
Wireless Mode - Auto
3. Yes. My girlfriends is sitting near me, playing same game on laptop without any issues. When I'm using USB tathering I also don't have any lags. If I will be able to switch between 2.4Ghz and 5GHz that would be great. Unfortunately I have no idea how to change it.
4. I'm not getting any messages. In Event Log for this device I don't see any errors/warnings. All I can see is that WIFI icon in tray is changing for "Globe" when I have "freeze" in game. After few seconds connection is coming back and I'm dead in game.
5-7. Skipping.
8. Driver version: 1030.29.1102.2017, Date of driver: 18.07.2018
OS: Microsoft Windows 10 Pro N (10.0.19041 Compilation 19041)
CPU: AMD Ryzen 5 3600
BIOS: American Megatrends Inc. 2.70, 21.04.2020
SMBIOS: 2.8
MOBO: B450M MORTAR MAX (MS-7B89)
MOBO Version: 1.0
Adapter was bought in online store. Sealed with foil. New one. Issue started from first minutes of usage. I belive it's Driver issue.

Update:
Router is located about 4,5m from me. One wall between us.
Like I said before - signal is great, Zero problems while using my Phone with USB Tathering.

Good day. In this way, please try to use the following driver to have a look:

1. I'm using WIFI connection. Not mobile data.
2. It's probably ZyXEL NWA1123 AC Pro, dual band.
3. If I'm not playing device is not disconnecting. If I download large files then device might disconnect many times while downloading.
I will try that driver tomorrow.

@Masakrator I have the same problem. Router in the same room, tp-link router actually.
It has been the same problem from the start but in the beginning I could both use it for 2.4G and 5G but then the 5G stopped working.
I changed the channel (46) on the router so my ac600 could find the G5. Fixed.
But I can not keep a steady connection on teams or zoom nor when I play online games.
I have tried both 2.4G and 5G.
The speed of my connection is above 150mbs so it should not be a problem.
BUT when I use my phone USB tethering it is not a problem.
I have used the link above for static tplink. It might actually have sped um my connection 10-15% but did not fix the big lag problem.
Please help.
