What is the operating system of your computer?
Can other devices connect to the host wifi?
Try to change the wireless settings of the main router to give it a go, including wireless channel, channel width and wireless password.
May it help.

@Kevin_Z Just Purchased the following
TP-Link AC600 Nano Wireless USB Adapter
Running Win10 Version:2004 Build:19041
It is a Fresh Load. Reformatted the HDD, Reloaded OS and Apps. Did all of that Hard Wired. Delivering to client, Installed the TP-Link AC600 and NOT able to connect to the 5Ghz Wireless Network. The 2.4Ghz works, however it is Quite Sssssslllloooowwww. Yes I have other devices connected to both Networks. I even went into the Adapter and changed the Wireless Options IEEE b/g/n and a/c and a/n and a/b/g/n still all failed with "Can't Connect To This Network"

Good day.
Thank you very much for your time and patience.
Is your model number Archer T2U, or T2U plus, T2U nano?
The current issue you have is that the adapter failed to connect the 5ghz, but 2.4ghz is fine right?
Did this issue start since you bought it?
If possible, please try to update the following driver to have a look:

(It is suitable for Archer T2U v3, T2U Nano V1, T2U plus V1;)
Thanks a lot.

Just created this account so I can post my findings. By day I work in a computer shop, so I can troubleshoot pretty readily. My T2U Nano purchased last week has never connected to my 5GHz home network. It DID connect to the 5GHz network at the shop. At home I'm running a Microtik dual band router, and the firmware is up to date. The 5GHz network shows up in my list of networks, it just gives me an error when trying to join. I've used the default Windows drivers, the drivers listed on the website here, and now the Beta drivers listed in the zip on this thread. The beta drivers wouldn't even install.
"Windows encountered a problem installing the driver software for your device.
Windows found driver software for your device but encountered an error while attempting to install it.
The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering."
I've disabled digital driver signing and they still won't install.
I'm willing to try something else if you're available to answer quickly. If not, I'll return the device for something else.

Good day,
Thank you very much for your time and patience.
Sorry for the delay.
May I know the model number of your home router?
And what Is the error when you failed to connect the home network?
Have you tried to change the wireless advanced settings on the main router, such as channel 36/40, channel width 40mhz?
As for the beta firmware, did you mean this one: https://static.tp-link.com/2019/201911/20191128/Archer T2U_V3_beta_windows 10 cannot link to 5G_1030.29.0627.2018.zip
And have you tried to put the driver into safe mode before you install the driver, such as : https://www.tp-link.com/support/faq/791/
Thanks a lot.
