DIAGRAM:
ISP < Mikrotik1 < Mikrotik2

PROBLEMS:
1.
speedtest.net to my ISP using wireless Mikrotik1 only got 5MB but if using cable got 18MB
2.
but if using wireless via Mikrotik2, I got normal 16MB

Are both of your mikrotiks same model? If yes, can you compare ouptut of between both of them to check if thare are some differences in how WiFi is set-up on both.

One thing I'd change in your setup is tx-power-mode=all-rates-fixed ... this typically doesn't work great at higher speeds and I'd change it to
Another thing: 951Ui-2nD is no high-performance beast. What is CPU usage while you're testing wifi throughput when connected to Mikrotik1? WiFi consumes quite some CPU, routing (done by Mikrotik1) as well, so it could be that CPU is a bottleneck here. Observe output of commands /system resource monitor and /tool profile ...

1. RESULT: 4.5MB
/interface wireless
set [ find default-name=wlan1 ] tx-power-mode=default

2. wireless export
Both same model and firmware

Are both of your mikrotiks same model? If yes, can you compare ouptut of

Code: Select all

/interface wireless export

between both of them to check if thare are some differences in how WiFi is set-up on both.

One thing I'd change in your setup is tx-power-mode=all-rates-fixed ... this typically doesn't work great at higher speeds and I'd change it to

Code: Select all

/interface wireless
set [ find default-name=wlan1 ] tx-power-mode=default

WiFi consumes quite some CPU, routing (done by Mikrotik1) as well, so it could be that CPU is a bottleneck here. Observe output of commands /system resource monitor and /tool profile ...

How's intereference situation? Mikrotik2 has fixed channel while Mikrotik has it set to auto....
WiFi settings on both APs are completely different (some of them might actually affect transmitted power). So why don't you just copy settings from Mikrotik2 over to Mikrotik1? If signal from both APs overlaps, you have to change frequency on one of them.

BTW, combination of settings on Mikrotik2 (country="united states", frequency=2447 and tx-power=30) is not legal. It might be legal in your country (whatever it might be) if settings on Mikrotik1 (country=taiwan) are correct.

already copied Mikrotik2 config to Mikrotik1
change SSID name, password, frequency
RESULT: still 4.5MB speedtest.net with Mikrotik1 va Wifi
Mikrotik1 to Mikrotik2 connected through cable
Wifi speedtest via Mikrotik2 speed is 10MB-15MB
Both Mikrotik same model and current firmware. Difference only factory fw which Mikrotik1 is newer than Mikrotik2
Any more idea?

CASE CLOSED:

SpeedTest Android App
Mikrotik1: 18MB

SpeedTest Windows App
Mikrotik1: 17MB

SpeedTest Windows Browser (Opera)
Mikrotik1: 4.5MB

SpeedTest website said to use windows app to get reliable connection.
When I tried that. I got similar result to Android app.
So I think. We should use SpeedTest app to get consistent result
