Firstly, the reason why i use mikrotik in the first place is help my dormmates get their internet connection by taking the 2nd floor of the building's wifi and take it to the upper floor by using SXT 2nd r3 and an access point to share the internet.

The thing is that the throughput is just very slow compared when using a phone to directly connect to the wifi on the 2nd floor.

1.5 MB dl with 2 MB up when using the phone,

while my mikrotik CPE can barely reach 400 KB throughput even when i put the phone and CPE side-by-side.

This is my current config. whats wrong here?
