MikroTik

Hi, i am Lim from Indonesia. I put 3 omni on my tower and i found a heavy interference issues (between the 3 AP), so i change my mind to use 3 piece of 120 degree sectoral antenna to serve my clients. I set their channel to 1,5,12 (that's the best i could get) and everything works fine until today afternoon. Suddenly the AP on channel 5 down (the clients couldn't associate), seems like someone is locking up the channel. When i change to channel 2 it works again but it interfere the other on channel 1. I am thinking is there any device or ways to lock the channel as i mention above? Anyone has got the issues?

Regards,
Lim

I don't if it is anyway that could lock the chanel 5 or likle this but can you see any device operating in this chanel maybe another ap does any of clients get asocieted or none of them and try cahnging the ap that operates in channel 1 to 5 and this one to 1 .

Try 1 , 6 , 11 channels...

I have tried to change the channel and i could get my clients back on channel 9 (but with 20% packet loss). I am curious if there's any device that could lock the channel as in my situation. Will it be a booster used by others in my environment?
