I recently got two used R600 units and the first thing I did was upgrade them to the latest Unleashed firmware 184.108.40.206.118. I was curious about the speeds I was getting through iPerf and Speedflex and after doing some reading it seems that it's been a known issue and I tried to resolve it by downgrading the firmware.
The issue that I have now is that both access points show disconnected when they're on 220.127.116.11.308 and 18.104.22.168.310. It doesn't matter if I set them up individually or together or do a factory reset after upgrading/downgrading the firmware. When I go back to 22.214.171.124.118 everything works fine.
Speaking of speeds, what should Speedflex be averaging in the AP to Client speed test on a mobile phone (2x2 antenna, 866 Mbps link speed, -26 dBm, 5 GHz) and AP to AP speed test?
