I have to monitor ip cameras by iphone, now it is impossible to work normally.

monitor the signal for a while, in the registration table. also, enabling debug log for wireless would be useful. http://wiki.mikrotik.com/wiki/Manual:Wi ... Debug_Logs

Signal is very good, iphone is near the router, not more than 2 meters. In registration it just disappear...
Here is debug log:

Try connect another iphone 4, same problem.

Works fine on my RB751G

Maybe some area interference, try change location, play with channels.

So, i try everything and found solution working for me. WiFi is mode only G, chain 0 tx/rx is disabled. And now all client has good CCQ about 24/54Mb before was 1/150mbit. When i enable chain 0, connection is very poor for all client. I don’t know or it is interference or just bad router.
