Bad performance/lag using CAPsMAN - AP in standalone mode fine

sirlindqvist · Mon Aug 03, 2020 4:09 pm

I have a problem that I cant find any solution for. I'm using an RB3011 as CAPsMANGER. I have one wAP ac connected and provisioned.

When I play games online, I experience several delays almost every minute. Take for example FIFA 20, when I play a match the whole picture / game freezes for 2-3 seconds. I can not control anything and the control does not respond. Then it releases and everything goes very fast for the game to "catch up". Then it can take 30 seconds and then it starts again. So it goes on all the time. I then tried to set up a wAP ac in a standalone mode which is then not controlled by CAPsMAN. When I use this, all the symptoms disappear. What could it be due to? Am I missing something in the configuration?

Here is the configutation of CAPsMAN (don't know if providing the CAPsMAN part is enough or whole router config is needed?):

If using the AP in standalone mode there's a lot more options to choose from than let CAPsMAN do the job.

Can anyone help me?

Select fixed channels, I use one per radio.
Set extension-channel=Ce (or Ceee) instead of XX
Nothing wrong with DFS
Use local-forwarding (on datapath)

I'll share my config for which I don't experience any of the problems you mention:

how does enable local forwarding helps?
I am facing quite the same issues over wifi with hEX s (CAPsMAN) + hAP ac^2 (ap)

erlinden · Mon Aug 03, 2020 10:30 pm

how does enable local forwarding helps?

If local-forwarding is not enabled, all traffic will be handled (and encrypted) by the CAPsMAN. This will cause processing power and will therefor always be slower.

Shy · Mon Aug 03, 2020 10:34 pm

ok good to know - you just fixed my slower speeds issues I had

thanks erlinden!
what is client to client forwarding?

erlinden · Mon Aug 03, 2020 11:04 pm

what is client to client forwarding?

From the wiki:

controls if client-to-client forwarding between wireless clients connected to interface should be allowed, in local forwarding mode this function is performed by CAP, otherwise it is performed by CAPsMAN

https://wiki.mikrotik.com/wiki/Manual:C ... n_Profiles

Shy · Mon Aug 03, 2020 11:19 pm

So for better performance it should be disabled?

I've configured with your settings now. However, provision dont work correct if i dont set Hw. Supported Modes to "gn" for 2.4GHz and "ac" for 5GHz. I get no supported channel on one interface and the 5Ghz interface choose a 2.4GHz channel. Also, do you use guest network with both 2.4 and 5GHz and then use the same SSID for this?

Shy · Tue Aug 04, 2020 10:47 pm

Well i "played" as well with my caps configuration and i found that sometime i get some of loss connection even if the laptop stays in the same spot. I lose some pings (5-6) then the ping rasies to 3000ms and ~2000ms and gets back to normal. When having few zoom calls it just freeze.

It didnt happen to me with meraki on the same spot. Configured with channel 2462 and 5180 with tx power 9 and 25.
Tried to use Ceee and Ce (i think that Ceee works better)
With local forwarding enabled for client to client and enabled in genetal on datapath.
I have 200mbit line connected to the hEX s as CAPsMAN and hAP ac^2 as AP.

Is there any difference between setting the TX power on the channel settings or on global configuration?

Any ideas?
Tnx

I use a/n/ac on the 5GHz band.

You should add your MAC addresses to provision the configuration to the correct radio. If you get "not supported", it is because the channel is not supported. What country are you in?

Guest network on both bands, you can't use the same SSID (unless you are using Radius). I use two VLAN's (HOME and GUEST) and set the corresponding SSID's to it. If you only use a single VLAN you can leave all VLAN related config out (the guest network can be added later).

If i set Hw. supported modes to gn on 2.4ghz provision and ac on 5ghz provision i dont need to manually set any mac address of the radios. Also, same SSID on both 2.4 and 5ghz guest network works if you do create an aditional 5ghz guest config and set the 5ghz channel. Whole config here:

If your data is on local forwarding then it is going across the bridges on the LAN between the CAP and your main router, so check the bridge config on both, could be related to STP settings, also make sure bridges have an admin-mac set.

Well i "played" as well with my caps configuration and i found that sometime i get some of loss connection even if the laptop stays in the same spot. I lose some pings (5-6) then the ping rasies to 3000ms and ~2000ms and gets back to normal. When having few zoom calls it just freeze.

With local forwarding enabled for client to client and enabled in genetal on datapath.
I have 200mbit line connected to the hEX s as CAPsMAN and hAP ac^2 as AP.

Well yes it has admin mac and bridge is set as Rtsp.
I have created nw thread tsince this one was marked ad solved i have attached my config files
