21-5-13 modify the applicable models of beta driver & update chipset driver
Hi,
Thank you for trying the Beta firmware for Archer C6, please disable " Smart Connect" on Archer C6, and set up different SSIDs for 2Ghz and 5Ghz band separately.
Please test for few days, and see is the 2Ghz or 5Ghz band unstable , or both Bands are Unstable?
For unstable issue, please try this chipset driver for T3U/ T3U plus:
If only 5Ghz is unstable, 2.4Ghz is working fine, you could also try this beta driver for T3U/ T3U Plus :

Good day,
Thank you very much for your time and patience.
May I know how long have you had the device and when did the issue start?
Did both the 2.4ghz and 5ghz drop the connection?
What is the model number of your home router?
If possible, please try to adjust the wireless channel settings on the home router, such as channel 11 for 2.4ghz; channel 36 for 5ghz;
And please also try to update the driver to be the following one:
(share the same chipset as the Archer T4U v3)

I bought the device a mounth ago. Issue started on first day.
Both the 2.4 and 5 ghz drop connection.
I don't know model of router, but I replaced it (got new from my ISP) last week and nothing changed.
Driver is up to date.

Hello, apologies for the late reply.
It is suggested to try my previous reply that update the public driver for this T3U Plus, which shares the same chipset as the Archer T4U v3:

If this doesn't help, please help confirm some details, and we will try to work it out:
1. Is it possible to try this adapter on another computer and confirm if the issue persists?
2. Is there any anti-virus software running on the computer? Can you please try to uninstall it and see if that makes a difference?
3. It is suggested to try to adjust the wireless channel and channel width on the wireless router, which may help to improve the wireless connectivity and range.
Good day.

Nope. It's worse now.
If I saturate the connection, my signal drops to 0 bars, the device then disconnects and crashes. I then have to unplug and plug it back in to get it to connect. Packet loss with a ping is in the 70% and round trip time to 8.8.8.8 or bbc.co.uk goes from 15ms to triple digits back and forth.
What is actually wrong with this device? I don't understand why the drivers on the products documentation page do not work, and why I am having to install drivers from your archive CDN manually to get a consumer device with a very common chipset to work on the most common Windows version.
The Windows plug and play adapter works better than every driver from TP-Link so far (some I have tried from this forum, linked by you, are open source or straight up recompiled realtek drivers). The problem with the Windows driver is that it crashes sometimes under load, and has terrible connectivity issues. At least it can stay connected.
I'm just going to get my money back and buy from a different brand, or save my money and just run a 30m cable to my PC.

Sorry to hear that. If the return window of this is open, you can just contact the reseller to return it. While if it is not, you can also contact the local tech support to check if they can help with a replacement:

@williamsf I've experienced the same issue and I think the problem is with USB 3.0. The adapter seems much more stable with a USB 2.0 port. USB 2.0 is limited to 480Mbps, but that's still better than most broadband speeds.
I thought there were many initial problems with USB3 ports being inadequately shielded on PCs and wireless routers causing a lot of instability. Maybe this is related to those issues?

This is also a problem. I have updated the router Archer c6V2 firmware, the usb wifi adapter has also been updated and it does. :
The old TL-wn722n - and it produces much better results ...:
