Hello, i am newbie to MikroTik.
I set up my MikroTik Groove A-52HPn as acess point but i have problems with speed.
I set band to 2GHZ-B/G/N and chanell widh to 20MHz and wireless protocol to 802.11
Mode is ap bridge and bridge mode is enabled. Frenquency mode is manual txpower and antenna gain is 0.

I have problem with speed of wifi, some times i have maximum speed of 10 Mbps, usually when i restarted acess point.
But most of time my speed is under 2Mbps. Always are 2 users maximum. When i connect my pc direct to switch i have max speed all the time.

I am testing now this hardware for installation at hotel acess point with maximum 50 users. Mikrotik will be positioned outdoor maybe 50 meters from hotel side. Should i change distance in settings or to set it as default?
Any help?

Sorry for my bad English.
