Hi I have a zf7962 that I am using in standalone mode.
when I first got the AP its was running FW 8.1.1 and was able to transfer 15-17mbps through it to two different servers connected at 5ghz.
please note I am the only 5ghz network I can see.
After updating the firmware from 9.0 up (9.0.1, 9.2.0, 9.2.1, 9.8.0) i am only able to get 3.5mb and it jumps up and down it doesn't matter how far away from the AP I am as currently im getting -27db signal strength.
I have also factory reset the device and tried 20 and 40mhz bands.
