My system has two network adapters. One is a PCI Qualcomm Atheros AR9485 Wireless Network Adapter. The other is an Edimax AC1750 USB Network Adapter, which I bought for 5GhZ band support after a router upgrade. It had always worked perfectly.
I just bought/installed a swanky new Samsung SSD, and I reformatted the old drive and reinstalled Windows 10 on the new one. I've run windows update until there's no further updates and everything seems to be working fine except the Edimax adapter. I did a speedtest and the download speed is around 0.25 MBPS (before the reformat it was around 90). Strangely, upload speeds are around 45-50, as they always were.
I've taken the following troubleshooting steps already:
-I tried using the Edimax adapter on my laptop. Seems to work perfectly, so it's definitely not the adapter.
-I tried switching the Edimax adapter to different USB ports on the reformatted system. Same result every time, so it's not a bad port.
-I tried disabling the Qualcomm adapter in the device manager just in case there was a conflict/interference or something. Didn't work, and the USB adapter worked perfectly before the reformat anyway.
-I switched back to the Qualcomm adapter on my reformatted system. Seems to work okay, albeit without 5 GhZ support.
I'm kind of at my wit's end here -- I figure it's probably something with the USB on the reformatted system, as the adapter is plug-and-play. Can anyone help?
