@Kevin_Z Literally I had a physical object leaning up against and pretty much covering my Antennas on the PCI card. (It was a laptop fan I was using for extra circulation of air into my machine.) Once I moved the laptop fan away from the antennas, I stopped having problems with the adapter not connecting to any networks. This is the second day I haven't had this issue anymore, and I have powered down my PC the night before and it booted up without any problems connecting to the internet.

Hi all,

I have done some pretty extensive testing to finally find a solution.

I have gone through all the steps in this link: https://windowsreport.com/windows-10-cant-connect-this-network/ + performed the latest Windows 10 updates (now on ver 20H2)

Along with all the suggestions throughout this forum post but unfortunately to no avail.

I actually have 2 x Archer T6E PCIe network adaptors which both do not work on my PC (v1.0 & v1.1). Reinstalled the drivers as recommended and countless reboots of my PC and modem. All other devices in my network have no issue connecting to my wireless network.

I noticed a few people mentioning issues with something physical impairing their antennae so I thought I would remove my to test, and wouldn't you know it. My PC connected to the Wi-Fi straight away (albeit very poor signal). I would be very interested to see if this solution works for others, and if it does perhaps TP-Link should look into a product recall of their antennae for this particular model. Especially considering this happened with 2 sets of the Archer T6E PCIe adapters that I own.

Important to note that I had no issues with the adapter on another PC so the problem is probably is conjunction with possible interference with where this PC is sitting (despite the signal indicator being full when I attempt to connect). I did notice that one of my neighbours recently set up a wireless printer so maybe that has something to do with it. Other than that, this issue seemed to come out of nowhere. I hadn't moved my PC nor introduced any other devices in my home.

I recently bought an archer t6e v2 to replace my old wifi card.

I had the same issue as everyone else where I could view available wifi networks, but not connect to them.

Saw your post and tried moving the wifi card from the pci-e slot between my fan and gpu to the bottom of my motherboard instead.

I can now connect to wifi a few minutes after my computer boots up and it'll crash for ~10 min every once in a while.

It's an improvement compared to before, but still pretty bad. I might as well go back to my old wifi card, at least it only crashes for a few seconds.

Update: There was a cable inside my desktop that was touching my wifi card. I've moved the cable to be touching the end of the card instead of the side and I now have no problems using 2.4gHz. 5gHz continues to be problematic.

I will most likely stop trying to fix it here, I am happy enough with 2.4gHz

Hi Kathy_Z,

I solved this problem 1 year ago (probably after the 2020 H2 Windows 10 update) using the driver you recommended.

However, windows has decide to upgrade again, this time to version 21H2. And this has broken the Wifi drivers again.

The symptoms are the same (I can see the networks, but I get the "can't connect to the network" error message).

I tried installing this driver:

that is listed in the support page, but it did not work.

I also tried to install again the Asus driver you suggested in your post, and it does not work either.

Is there an updated driver that would support Windows 10 21H2?

Many thanks,
Nicolas

Including here screenshots of my driver version and OS version:

Asus driver:

(Please note that I also tried with the generic Broadcom driver included in Windows 10 and with your "Archer T6E(US)_V1&V2_200603_Win10" that I mentioned above).

@Anthony_Thet Kathy_Z

I bought a new Archer T6 and windows 10 is 21h2

i have the same problems as described.

I can see the networks but if i want to connect and give the wpa password de card tries to connect but it's times out and is saying the password is incorrect.

i tried al drivers different places in the house, my other devices can connect to the wifi.

is there a new driver for windows ?

regards

Roger
