Bit of a strange one that I've been wrestling with and can't seem to resolve. Wondering if anyone else has an idea?
Setup:
ASUS RT-N56U router broadcasting 2.4GHz and 5GHz signals with WPA2 AES.
Desktop PC with TP-Link TL-WDN4800 PCIe adapter.
Since updating to Windows 8.1 I've had poor wireless performance and the inability to get internet connectivity on 5GHz at all.
Symptoms:
2.4GHz connects, but is slow and having started a download, bandwidth increases then tails off until it's running like a 56k modem and stays there.
5GHz connects, but with limited connectivity so no internet. Can see the router, but doesn't get into the UI properly from what I can see. Odd.
Things I've tried without success:
Update router firmware
Every driver (new/old/3rd party) for the PCIe adapter
Windows 8 command line network stuff - clearing caches, configurations etc.
Weird thing is, it was all working properly before Windows 8.1. Unfortunately, short of a clean install, I can't see how to roll back to 8.0, nor would I like to as I'll still have this issue one day. All other network devices work fine and I'd be willing to put money on a CAT5 cable having no issues either. Any suggestions?
