Hello!
We are having trouble with an Mesh-installation where we are using CAP2702e in weather-proof enclosures and a WLC5508 running r8.0.115. The APs is connected to multiplexers/filters that divide the signal to 2,4GHz Omni-antennas for the clients and to 5GHz panel-antennas for the backhaul.
One RAP is mounted on 12m height and should have 3 MAPs connected to it in an "A-form", the two APs (MAP1 & MAP2) are at the end of the As "legs" are at 500m and AP3 in the middle (A "crossbeam") is at 300m. All use channel 104.
The first RAP is installed on the roof-edge of a building and the MAPs on masts.There is also a second RAP on the same building as the first but on another wall 90 degrees removed and using another channel and another BGN, this RAP has a single MAP connected to it which have no problems. This pair use channel 100.
All of the first three MAPs share a BGN and the MAPs have "preferred parent" configured to RAP-1. All three MAPs have an SNR betwen 28dB and 32dB. When we do a link-test MAP3 gets a PER of 1% and MAP1 & MAP2 gets a PER of >50% !!
Also, clients connected to the MAPs on the 2,4GHz-radio says that they experience excellent RSSI and high data-rate but their ping-times vary wildly between 10-15ms up to 1000ms ......
Another issue is that the MAP1 and MAP2 very often will "switch" to RAP-2, which is using another BGN! So, any bright ideas on where to tweak and change?? Mesh-distance is configured globally to 3000ft (1000m).
Best Regards
