I am totally new to Mikrotik and I am on a quite steep learning curve…
My today’s challenge is to set up a cap AX in the best possible way.
It is behind my WAN router and I can connect to it, Internet access is working, however it is quite slow.
As a first check I used the Android “analiti” app which shows
download 19Mbit/s upload 9.5 Mbit/s for the 5GHz
download 18Mbit/s upload 8.3 Mbit/s for the 2.4GHz
Whilst measuring it I was sitting about 10ft below the cap and 2ft aside. So not far away - maybe to close?
To optimize the setup I first checked frequencies of WiFi neighborhood.
Using WEBFIG I can see 48 other WIFI Networks, some with the same SSIDs their Signals are between -64 and -97.
I expect (hope) I can ignore the weak ones under a certain level.
From what level upwards should I take them into consideration when choosing the frequency of the capAX ? Or is there a kind of "auto mode
Last question for the moment…, can I check/adjust the transmitting power? I want keep it on the minimum required to ensure coverage.
Best case I only screwed up the setup 
txs for any help
