We are seeing strange performance issues when using the A5c with any of the C5,C5c,C5x clients on 100mbps plans.
Our setup is as follows:
APs (in SRS mode, 40MHz channel):
Setup 1: A5c w/ 2 RF Elements 90° Horns
Setup 2: A5c w/ N5-360 Omni
C5, C5c and C5x
(I am aware of the 100mbps max base license on the C5x)
We have a total of 5 APs deployes with the RF Elements horns and another 2 with the omnis. Each AP only has one or two customers on them so far, with one hosting 6 clients.
We are definitely not saturating the user load on these APs with the above numbers. Most customers are also within 300 meters of the APs.
We set our clients on 30, 50 and 100mbps speed plans. We only have one client on a 100mbps plan so far, the others are all on 30 or 50.
The majority of the clients are connected at MCS 9/9, with a couple bouncing between 6 and 7 on the rx.
Everyone on the 30 and 50mbps plans are working fine and speed/throughput testing shows these speeds are being attained. However whenever we set a client on a 100mbps plan (MCS 9/9) we are getting a max of 70-75mbps download when running various speed tests, iperf tests and Mikrotik Btest’s. When I set up both a test C5 and C5c to a 140 or 200mbps plan and connect to any of the APs, I see 100mbps and 160mbps accordingly, but never get my full speeds for the plan.
Has anyone else seen issues when using 100mbps plans or above using C5 or C5c radios connected to an A5c?
