Thanks for the update. I tried to run speedflex (to AP I am not connected to), iperf3 to wired server and speedtest. Here is the results with iphone x as a client.
1. Speedflex to second AP: download 128mbit/s, upload: 274mbit/s
2. Speedflex to connected AP: download 117mbit/s, upload: 278mbit/s
3. iperf3 to local server wired to AP 5 streams: download: 134mbit/s, upload: 144 mbit/s
4. Speedtest: download: 134mbit/s, upload: 133 mbit/s
Before new firmware download speeds were ~80mbit/s
It looks like good results, but with anomaly in upload speed with speedflex. Is it?
Also, I found one strange thing. If i run dslreports test, it shows "C" for buffer bloat. If I run it with another cheap AP, I get A+ result. What type of configuration should I check on Ruckus AP to fix it?
