The distance between the remote and local AP's is about 250 feet.

I did some checking, I set up a local speedtest server on the remote side, and tested from my phone by connecting to the remote AP and speedtest server connected to that AP.... I get about 600 Mbps +/-.

I did the same thing on the local side, I set up a local speedtest server and connected to the local AP, but I only get about 300 Mbps.

Speedtest between remote AP and local speedtest, and Local AP and remote speedtest are still coming in at aroung 80-100 mbps though.

Both are connecting at 80 Mhz bandwidth, on the same channel. 

I've replaced the cable feeding the AP that was having the issues, but that doesn't seem to have made a difference. 

I have another AP right next to it, and I did speedtests connecting just to that one locally, and it comes in aroung 600mbps, but the one with the issue only comes in aroung 300mps.... Swapping the cables between the two didn't make a difference, so I doubt it's the new cable. Could the AP just not be working right? The one with the issue is older than the other one.... but both have the same firmware and hardware revision v1.0.

Thanks!

I'm using Open speed test locally hosted on windows machines at each end of the link (not going through the internet). I'll test with iperf, and see if there is any difference but I doubt it.
