Wireless network infrastructure consist of four sectors based on Cambium AP 450i.
Each sector has one Access Point.
Uplink and Downlink rates of sector 2, 3, 4 are MIMO-B.
Sector 1 has Uplink rate MIMO-B and Downlink rate MIMO-A.
The situation is as follows. If any Subscribe Module from sector 1 connects to sector 2, the Uplink and Downlink rates become MIMO-B. And if any Subscribe Module from sector 2 connects to sector 1, the Uplink rate becomes MIMO-B and Downlink rate becomes MIMO-A.
I wonder what could be the cause of such a behaviour?
Hi Jacob! Thanx for the replay. We do have the rate adapt algorithm set to MIMO-A/B. All the settings are the same for all the sectors. APs have the latest firmware updates. But only sector 1 has such a behaviour. And we don’t understand why it is happening. Maybe there is a way to diagnose the problem? Maybe some kind of tests?
