Archer T9E not connecting on 2.4ghz
So I have been using the Archer T9E for a year now with no real issues. Both the 2.4ghz and 5ghz channels were fast and fairly stable.
On Monday (5 days ago as of writing this) everything was fine. 2 days ago though the interent wasnt connecting, at first I figured it was the router so I restarted it but it didnt help.
I went to bed frustrated after trying a few things.
Yesterday I brought the computer downstairs so I could hardline it to the router which had no issues.
If I try using the 2.4 ghz frequencey I get almost no download speed (on speedtest) and no upload.
If I switch to 5ghz it connects ok, but the download speed is about 30% of what it should be. Also the upload speed is 0.5 mbs (should be closer to 300)
Ive tried deleting/installing the drivers, restarting the router, returning the router to factor settings and going from there.
Also changing the different channels but nothing seems to work.
(The TV, my phone, wifes phone and her labtop all have no issues and can connect with great speeds)
Also if I use an ethernet cable the internet is fine and so it my download speeds.
I physically unplugged the card, and even tried a different PCI slot. All the same.
Any other ideas would be appreciated... everything points to the card.
