Hey folks I've been having this problem for the past two weeks. My WiFi has been giving me a max of around 5 mbps download in normal windows operating mode, however if safe mode with networking I get around 15 mbps. I've tried many different solutions including: reinstalling drivers, getting a more generic wifi driver, flushing my DNS, updating windows, clean booting windows, restarting the router, choosing the optimal WiFi channel and running antivirus scans and malwarebytes scans. I connect to the 5GHz AP on the router even though I am fairly far from the router (I get about 24% connection strength) as it gives me much greater speeds than 2.4 GHz even at this range. My wireless adapter for my desktop is the Archer T6e AC1300. I have also fiddled with some adapter configuration changes to no avail. If anyone has any advice or possible solutions please let me know.
