Dear sir,

I have problem about wireless connection, we have +/- 50 clients using jaht wp-4001br as station and connecting to a rb600 as ap within RouterOS v 3.20, our question when we see in registration tables all clients that registered suddenly disconnected to the ap and then connected again several times , and then we look in registration tables all clients signal strength is become 0, we'll show our configuration and error log here at below ;

Does anyone know what we must to do or have solution to resolved this problem? . TIA

Regards,
Ojiex

first, increase your wireless logging information. Maybe then you will find your answer why they disconnect?
http://wiki.mikrotik.com/wiki/Wireless_Debug_Logs

On 2,4GHz only two nonoverlap channels.Check 802.11g spectral mask. It's time to go on 5GHz band.

Good point 'aaa'!

2412 - Ch1 BiGnet03041
2432 - Ch5 PE-Maleo0304
2484 - Ch14 BiGnet03042
2472 - Ch13 BiGnet03043

It is not perfect as there is still some overlap, but maybe you should change to :
2412 -Ch1 BiGnet03041
2432 - Ch5 PE-Maleo0304
2484 - Ch9 BiGnet03042
2472 - Ch13 BiGnet03043

Not sure Ch14 is legal in your country. Ch14 only allowed in Japan?

Ok, it's confirmed my problem resolved now, we change main wireless bridge into 5 Ghz and the rest AP bridge still use 2,4 Ghz, about country Japan selection and ch 14 because still too many interference in ch 11 - 13 and we gain best fit signal and data rates for our clients.TIA
