I have a tower with 3 sectors on it. Running channel 1, 6 and 11. I have a few customers whose signals are around -74 to -77. For awhile now they have been dropping lots of pings at times. If I turn off my other 2 sectors the problem appears to go completely away. Every time I sent Mikrotik info about this, even once I sent them some output files I just get told to try and upgrade to the latest version. Right now I am running 6.19 with NV2. TDMA Period size is 2. I haven't seen anything in the change logs for the latest versions that would lead me to believe anything has been done to the wireless. Does anybody have any ideas about what is going on here?
No these are 3 separate boards. One board per sector. Units are in metal cases. To me it is obvious that they are somehow interfering with each other but this used to not be the case and correct me if I am wrong but being on channel 1, 6 and 11 should not be interfering with each other like this.
I am not using dhcp. We are doing pppoe. I changed 11 to 9 and I am still seeing the same problem. With one sector on ping times and connection looks good. Turn the other 2 back on it get weak again. I wish someone from Mikrotik would see this and respond. Clearly they are interfering with each other when they shouldn't be.
This spectral scan shows what I am talking about. If you look you can see where I turned off the APs on channel 1 and 11 off and then turned them back on. You can see how far outside the range they are going. And how much of a change there is on channel 6.
