CAPsMAN & Wireless Speeds

psybernoid · Mon Jan 29, 2018 9:55 am

Hi all,

I'm struggling to get the best speeds possible from my home CAPsMAN setup.
First, an overview of my infrastructure:
I have 2 wireless devices, connected to an RB3011 which is acting as the CAPsMAN server. Those devices are:-
RouterBOARD 962UiGS-5HacT2HnT
RouterBOARD wAP G-5HacT2HnD

I also have a Ubiquiti UniFi-AP-AC-Pro which I'm testing to.

With the Ubiquiti (located one floor up in the house) I'm getting the following speeds:
247.56 Mbit/s Rx
281.11 Mbit/s Tx

With the RouterBOARD 962UiGS-5HacT2HnT (located with full line-of-sight in the same room, 6` away from the laptop) I'm getting:
192.40 Mbit/s Rx
259.46 Mbit/s Tx

Which isn't too bad, but I feel the 962UiGS-5HacT2HnT has more to give.

I've exported some of the config:

Am I missing something here? I'm quite new to CAPsMAN

We are experiencing the same problem.

We operate a network with ~150 customers directly on full fibre connections. For the client CPE we are using Mikrotik HAP AC.
Speed tests with a computer directly connected to the HAP AC give results between 250 and 350Mbps download and >400Mbps upload depending on how heavily the network is loaded.

The majority of the customers are using the standard WiFi setup, with separate SSID's for the 2Ghz and 5Ghz wireless

To improve WiFi coverage for some customers we have installed additional Mikrotik access points (cAP), connected via Ethernet cable to the primary HAP AC, and have switched over to CAPsMAN so the customer can move seamlessly between the HAP AC and the slave access points.

In every case, where we have moved to CAPsMAN we have seen a significant reduction in the wireless speeds, so this evening I have attempted to do some more scientific tests.

Hardware - HAP AC running 6.43.8 (Firmware and Router OS)
Hardwired speed test using a Microsoft Surface Book, directly connected by Ethernet cable - 267Mbps down / 448Mbps up
Wireless speed test using a One+ 6:
- Using the out of the box settings in the HAP AC, 5GHz wireless - 190 Mbps down / 194 Mbps up
- Using CAPS also on the 5GHz wireless - 74Mbps down / 91 Mbps

These results match what has been observed in our customers' houses and are repeatable,

Some screen shots:
Using the built in Wireless:

And using CAPS

One further observation - we seem to get better speed test results when the wireless device is connected to the slave access point (Mikrotik cAP) than when it is connected to master HAP AC.

Is this an issue that needs to be raised with the Mikrotik developers or is there something that we can tweak in the CAPsMAN settings to improve performance?

Thanks
Chris
