P.S. RouterOS 4.4

What is your signal, antenna type, noise floor, etc.?

What is your signal, antenna type, noise floor, etc.?

Signal post later, but I am at 3 meters from the ap-point (rb493) and on PDA ASUS P750 (wireless client) I see a good signal. Antenna type - indoor mikrotik 2.4-5.8GHz Swivel Antenna, connect to J3 connector on R52N (only one antenna connected).
Noise floor - -107dBm.
Band - 2.4GHz-G or 2GHz-b/g/n

what information still needs to provide?

whats wrong? bad R52N or bad client? or RB493? or RouterOS problem?

Situation was resolved, problem was in pda asus p750 in WM 6.1 power(battery) profile(settings), not in routeros or r52n.
