I have one mikrotik sxt5 5HPnDr2 as AP from Home with a nanosation5 at the shop, I shared home internet via the Mikrotik to shop using PTP.
at Home when I test the internet the speed is 35Mbps , ping is 18 but at the shop when I test the Internet maximum speed is 14Mbps ping is 18 which shop's nanostation (signal is -30dBm ,Noise Floor is -80dBm and CCQ is 98% ) both are very high from floor and the distance between those nearly is 350m . and no building or any other thing between those. you can see any devices from above, for example from the shop I can see clearly home's nanostation.
please help me and explain to me why the speed is 14Mbps when the signal is -30dBm it's not good signal!? near my both devices have 2 small internet Tower and 1 cellular tower, does it affect my PTP internet quality?
how to solve this problem and get the best result.
