I am using RouterBoard 911 5HacD in ap bridge mode. I am essentially using this board to create a WiFi out of EdgeRouterX (https://www.ubnt.com/edgemax/edgerouter-x/).
I am getting 0.8 Mbps download and 3.81 Mbps upload speeds (ping 17 ms) when over routerboard’s wifi.
If I hardwire my computer to the EdgeRouter I get, 52/42 Mbps (down/up). And if I connect a different Access Point on the EdgeRouter, I get 26/23 Mbps over WLAN.
Any changes I can make to improve the WLAN bandwidth of the Routerboard? You can find some settings screenshots attached.
