Perhaps this is what's also wrong with my T8E...Edit... Same issue as you have, but it appears mine shit the bed before the 1803 update as that's still a pending download. It installed KB4099989 on 27th April... T8E hasn't worked since, and Windows won't let me uninstall it or roll back to a previous version.

I contacted their support and they've confirmed it's an issue with the latest Windows update. They're communicating with Microsoft to resolve it, it seems.Also, I found that the issue only affects secured networks and not open networks.

Now if only I could get an internet connection on my PC to download the updates once it's fixed... ?

Hey guys, any news on this problem?
I had to revert my windows installation to 1703. Even 1709 did not work.
That is annoying!

Try connecting to a 5Ghz AP instead of 2.4Ghz My router supports both and have I have no problems connecting to 5Ghz with my T9E, but cannot connect to 2.4Ghz.

What problem? My Archer T9E works fine with Windows 10 1803 build 17134.112

Consulted the same issue with tp support few days ago.
They explained microsoft updates the adapter's driver when they update the windows version together.
That driver hasn't been test by tp-link, so there may be some issue with it.
Try to download the driver for win10 from tp-link official website.

Hi,I'd like to report that the Archer T9E V1 is not compatible with the latest Windows 10 update (April 2018 - 1803). I can no longer connect to any wireless networks using Windows or the utility. Reinstalling the drivers, restarting etc. does not resolve the issue. The T9E still works with my Ubuntu installation so it is not hardware related.Please address this as quickly as possible with a driver update, as the wireless function of my Windows installation is now broken entirely.Thanks

Can you access both 2.4ghz and 5ghz networks? I can only access 5ghz.

I just bought the adapter yesterday. Installed it and everythin was all right.After one reboot the adapter stopped working “Cant connect to the network”message after typing wifi password.Using Windows 10 Ablil 2018 - 1803 update.I tryed uninstall clean remove drivers etc... but after installing again I get the same issue.Same problem in 2.4Ghz and 5Ghz. Both WPA2AES.Installed old PCI wifi adapter in parallel also from TPLink and this one works fine but the 65€ TP-Link T9E not. (So it is not a windows issue. It is a T9E driver issue.I fell a little bit dissapponted with TPLink. I was doubting between this one and the Asus. Now I regret.Please release and unpdated driver. Didn’t you test it before w10 1803? This kind of thingh kills a brand.
