CAP AC - lag spikes, bad connection

[trollinger0815]

Hi there,

I don´t have that much experience with Mikrotik or network settings in general.
But I was able to setup my CAP AC, but it has a terrible performance.

Current setup:
TP Link Archer (is as well the router for internet connection) WIFI for first floor. (good performance)
TP Link Archer is connected to MT CSS326-24G-2S+RM and CAP AC is connected with this switch.
CAP AC for second floor. (bad performance)
I have another CAP AC which I would like to use for the Garage or Outdoor later on.
I tried already both CAPS they are performing the same. Different settings etc. with no luck.

The device I am mainly using the WIFI for is the amazon prime stick for Netflix and IP TV.
But especially the internet TV is extremly frustating. Constant lags etc.

Prime and Netflix is not that bad, because I guess it is buffered enough so it can run stable.

When I am using my phone for webbrowsing the performance is as well extremely bad.

So I think it has something to do with my settings of the CAP AC.
I just did a ping with the winbox to the prime stick while watching it has ping spikes (see screenshot)
I did as well a ping speed and the speed it jumping up and down from 17.6 Mbps to 273.1 Mbps back and forth.

We are living countryside (GER), there are not really that much other WIFIs around.
But I did a scan in the past and tried to sit between the others with no difference in performance.
So I switched back to auto channel.
I had as well let the TP link handle DHCP and currently the CAP AC, but no difference.

Do you have any idea what could cause such an issue?

Wireless settings seem ok. If you can move 5ghz to AC only even better but often people have older technology N, still in place.
What channel width are you using (I use 20/40Mhz-Ce) which works best for me!

Is your capac in wisp mode??
Mine is in wisp mode and I dont try to use it like a router.
NO POOL for example as the routers do DHCP.

I dont use auto channel I use my iphone or other apps to see what channels are free etc…

How is the TP archer providing you with two subnets for your different WLANS??
How many subnets do you have??

HI there,

thanks for your reply and sorry for my late answer.

At that evening I did something wrong and since then my CAP acs are not working.
Hadn´t had the time to since then to have another look.

I just did and seems I have to reset them again.

One CAP won´t even show up in my windbox the other shows up but I can´t connect.


So I will going to reset both again.

“Wireless settings seem ok. If you can move 5ghz to AC only even better but often people have older technology N, still in place.

I tried AC only I tried 20/40Mhz-Ce and also other options, but it doesn´t matter. It won´t improve anything.

“Is your capac in wisp mode??
Mine is in wisp mode and I dont try to use it like a router.

Not sure if I tried wisp mode but I tried both to not give it a DHCP Pool and to give it a DHCP Pool. Again doesn´t matter won´t change anything.

“How is the TP archer providing you with two subnets for your different WLANS??

I think I don´t have two subnets? I am actually not familiar with the theory behind it and therefore can´t really answer that question.

“You should have stuck with tp link as their eap245v3 is way better for the same price (more stable and higher speeds).”

I am really considering it at the moment as it gets just more frustrating. As it feels like I did try every setting and it won´t work at all.
Sometimes my CAPS won´t get Internet connection from my TP link and sometims it´s working but extremly unstable.


/edit while writing this comment which took a couple of minutes I am now able to connect to one of the CAPs

I am using it in the Home AP Dual mode. I will try the wisp mode now and remove DHCP from the CAP

/edit 2 is it normal that there are two differen MAC addresses ?

[holvoetn]

Mac addresses are normal.
One for wireless ITF (there should be 2) , one for bridge.
