Very Nice Thank You
Perfect!
I’ve been needing this for months!
Hi all.
I tried this functionallity and it works really well.
Is this then active by default?, I mean, every log is sent to memory after any event (that I choose).
Thanks.
I’m getting the MIC Failures on several of my clients. Interference isn’t an issue on one of them and their signal is -50, ccq is around 99.
Client is conecting to a RB112/CM9 using a laptop. Two other customers are using Tranzeo CPE 90’s.
They connect fine…then out of the blue I see those MIC failures.
Is there another explanation for the cause of these? Or is it just a compatibility issue between the cpe’s and ap and using TKIP.
Thanks
Advice for “no beacons” if connecting to a Cisco AP, you need to increase the beacon rate on the Cisco radio config. Default is 100 and all my routerOS clients constantly dropped with this error, changing to 50 and it’s rock solid.
Congratulations! This information is very helpful.

Thank you! 
Talking about disconnection.
I suffered mainly two problems.
a) trees disturbing registration, so, moving antennas was the solution
b) excesive power on antennas, so, N/S ratio was too poor
I solved this problem, today not disconnection messages since 3 months ago!
Thanks.
thanks guy good work .. it help us !!
