I have a Negear RAX29. I purchased 500mbps download speed from fiber company. If I test the speed at the router, its saying 500mbps. I have a brand new TP-Link AX3000 (TX55E) Wifi card installed on my pc. When I run any speed test I am only getting around 80-100mbps. Any suggestions? I am connected to the 5GHZ band. Channel is on 48 and set up to 1800 speed. This is frustrating. If I connect hard wired I only get around 200ish. Is my router a bottleneck?
