Hello everyone, first time posting here. Appologizes in advance in case this post break any rules.

I've own this T9E archer for 6 years, and never had issues with until recently. Suddenly I get connections slowing down to half then back to normal, constantly (Download and upload), and all goes away when I reinstall the last available official driver " Archer T9E(US)_V1_170831_Wins". I Open the .exe and repair the driver. Connection is fine, than 1/2 days later it slows down in the same manner until I update again, and everything is fine. This has come to my attention in the last month or so, but I'm not sure how long this could've been going unnoticed (was blaming on the ISP, router, until I found out it was only my computer with this problem)

Not sure whats going, i'm assuming windows is messing up with the drivers?

Best regards.
