Hi, here is the latest public driver for the Windows 10:

Refer to the link to install it manually, please remove all the other drivers that you have installed on the computer for the adapter:

@Gabesz 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? 

 

If both bands are unstable, please try chipset driver provided by @KevinZ in the recommended solution

If only 5Ghz is unstable, 2.4Ghz is working fine, please try this Beta driver for T3U/ T3U Plus/ T4U (3 models use the same Beta driver):

@williamsf 

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

Thanks a lot.

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:

https://static.tp-link.com/2019/201911/20191128/Archer T4U V3_TP-Link driver_1030.22.0202.2018.zip

 

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.

Hi, The file that you are recommending to install with these new drivers are from 2018 (when the current drivers are 2019 1030.29.618.2019) , is that correct and are these the recommended ones for t3u plus? How do we install them? there are just folders with drivers without instructtions or installer. Thanks

I have the exact same adapter with the exact same problem. I have two of them on two different machines. Both just disconnect, sometimes the USB device actually crashes. Where did you get the 2019 driver from? I have the 2018 driver for the T3U.

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 ...:
