bandwidth limitation on RB500 ...

RouterOS Wireless Networking

Hello,

I have installed 3.0betaRC11 on RB500+CM9 as AP-bridge(wds enabled) and 10 Mktk station-wds clients so pretty straightforward configuration model (Nstreme is not enabled).

If at least 3 clients utilize ~2Mb/s per client (simple download) what makes 6Mb in total on the RB500 Access Point the available bandwidth of that AP doesn’t exceed ~ 100kb/s + extremly high ping time on every client (latency issue).
Point-to-Point (Bridge ↔ station-wds) works well and doesn’t have the same issue.

Does anybody experience the same problems and how to improve AP capability to handle in that scenario 10 wireless clients x 2Mb = ~20Mb in total through wlan1 interface ?

Frankly, I have never seen RB500 + Mktk ROS in AP-bridge mode to be able to handle more than 6Mb/s ! Maybe this is a real limitation of that board or a certain limitation of an Atheros card itself.

Described problem is the same with ROS ver. 2.9.x

Hope somebody will answer this posting.

Thank you,
D.

On a RB532, use 2.9.50 and NStreme. We have boards that are happy up to around 20mbps aggregate (half-duplex) traffic in multipoint settings. Each sub is rate limited and all are connected at 54mbps, so there is no contention for wireless bandwidth.

I think I haven’t completely understood the explaination “20mbps aggregate (half-duplex) traffic in multipoint settings”.
Would you be able to detail the words.

Thank you for the response,
D.
