So here's my connection rates for my devcies on 5Ghz:
Current connected client(s): wdev1ap0 getstalistext:
1: n ASSOCIATED Rate 1300 Mbps, RSSI 60 A 64 B 66 C 67 D 64
2: n ASSOCIATED Rate 975 Mbps, RSSI 61 A 70 B 63 C 71 D 63
3: n ASSOCIATED Rate 702 Mbps, RSSI 69 A 64 B 64 C 62 D 68
4: n ASSOCIATED Rate 702 Mbps, RSSI 70 A 60 B 63 C 71 D 68
5: n ASSOCIATED Rate 780 Mbps, RSSI 72 A 69 B 70 C 66 D 57
6: n ASSOCIATED Rate 1 Mbps, RSSI 73 A 64 B 72 C 76 D 79
It's nice to be able to see connection rates on the sysinfo file. I wish they would put it in the routers UI.
