About a month ago I bought a wifi adapter. Up until now I've always had the computer set up within cable reach of the router.

Running Window 7 Professional 64-bit

From the start I have experienced dropouts. Tested the router and it's fine, laptops and phones all connect.

I contacted TPLink support and got a very mixed bag. I was repeatedly told the driver needed updating, despite the link that I was sent reinstalling the old driver.

The driver link listed at the top here https://www.tp-link.com/au/support/download/archer-t9uh/#Driver installs driver 1030.22.405.2017 with a driver date of 11/09/2017

When the connection fails sometimes it will sign back in, other times it will get me to run diagnostics. Sometimes it will reset the network adapter, other times it will ask me to check the Network Security Key. The password has not changed.

Any suggestions at this point would be greatly appreciated.

Thanks
