Built in Wi-Fi vs cAP performance speed difference

RouterOS Wireless Networking
1

Hi. I am a novice in networking but have been enjoying learning the routeros!
I have been using the RB2011UiAS as my wifi device for a while and I’ve been very happy with it.
Not long ago, I did purchase two cAPs and did configure them as access point for a new SSID. So currently there are 2 different SSID broadcasted.
One from the RB2011 and one from cAP.
For some reason the speed on the cAP is much slower when I do a speed test… 5Mbps and 30Mbs on RB2011.
I am still trying to figure this out why but am having trouble with it…
I would appreciate any input on this…
Thank you!

Interference?

Thanks for your reply. Do you think turning off the wifi from the router would help?

Make spectral scan on both devices and select the best mutually far enough frequency ranges on both devices.

Hey Jarda,

I apologize for late reply. I was away for the holidays. I will try to do some spectral scan and see what is going on.
Thanks for your help!

Remember cAP is mono chain, 2011 has dual chain wireless (two antenna/polarisation) so the latter has double the speed (in perfect conditions) and has better resiliency in noisy environment

Bajodel,
Thats very interesting and makes sense.
So in my situation, with one 2011 and two cAPs, is there a way to run only 1 ssid through 2011 and cAPs?
It just doesn’t make any sense to not use 2011’s dual antennas when it’s faster than cAP.

Jarda, also I did run the specitral scan and it looked fine. My only question is what is the suggestion in the cAPs frequency? Is it possible to run each with different frequency using capsman?

I had also horrific speeds from cAP, only thing that helped was setting it to G/N only mode.

sure, set the same ssid/wpa2 on all 3 ap (2011 and 2 cAP). If you have clean full spectrum set 1,6,11 channel respectively (or if they are not too close you can reuse the cleanest one)

Jarda, also I did run the specitral scan and it looked fine. My only question is what is the suggestion in the cAPs frequency? Is it possible to run each with different frequency using capsman?

yes, with or without capsman. For 3 ap I would personally avoid capsman because direct configuration has more tuning possibility and no capsman overhead.

Ivicask,
That’s very interesting. I have mine set to b/g/n mode.
I will try to remove b tonight and see the difference.

just a note.. I see now there is an updated/new cAP version wich is dual chained, what version do you have?
