Failed to connect to the 5GHz with T2U/T2UH after upgrading Windows 10 OS version
Failed to connect to the 5GHz with T2U/T2UH after upgrading Windows 10 OS version

Hello,
It was brought to our attention by a number of customers of a failure to connect to 5GHz that happens after upgrading Windows OS. What will happen is devices are unable to connect to the 5GHz of the main router, while the 2.4GHz works fine.
If you are experiencing this issue, please get in contact with our technical support staff. They will be able to provide instructions to help update the driver of the network adapter to solve this.

@Kevin_Z I was unable to install this driver. Windows 10 complains that the hash for the file is missing. Disabling mandatory driver signing via bcdedit doesn't change anything.

Hi, what's the model number and hardware version of your adapter? Did you try the driver on our official website?

@Kevin_Z I am also confused in this regard, but there are wiresless routers that are manufactured by TP Link and this is the main reason behind my research.
Moreover on the other side the TP links connectivity to the android devices also so powerful
