I finally upgraded to fiber from ATT. I have everything working, yet I am getting much slower speeds from either access point than if I connect to the att router itself. I have the 1gig service and from the ATT router I can get 828down / 647up, but when I connect to AP (2 - R510’s), the speeds drop down to 367down / 310 up. I’ve cracked 400 a few times, but that’s still over 50% loss. I have the TX power set to full on both AP’s but still between two AP’s, I get tremendously less speed than if I were to connect to the att router itself. My complete system consists of ATT modem/router, to the edge router 4 to an ICX7150 switch that the two AP R510’s are powered with on the unleashed interface.

Hi @tim_adams,

All we have to know in this scenario is the wireless link speed. Accordingly client could achieve internet speed. To know the link speed and MCS value run below command from AP CLI. From Master AP, you would need to turn on AP-mode.

get mcsrate <wlan_id> <client_MAC>

The MAX link speed 11AC client could achieve with 2 spatial streams on 80Mhz bandwidth and short guard interval is upto 866 MBPS. With this link speed assuming minimum airtime utilization, client could achieve 750 to 800 MBPS of internet bandwidth.

Please refer below table for more info on MCS Table.
