MikroTik Audience slow speed WiFi, why?

RouterOS Wireless Networking
1

Hello

For several days I have an UPC 500 Mbit optical fiber connection.
On the ConnectBox router from UPC to WiFi 5GHz I have a nice speed of 450-500 Mbit / s, and after Audience only 200-250 Mbit / s.
I’m using MacBook Pro 2019.
What could be the reason? Do I have to configure something in MikroTik with default settings?

Please help.

You never have optimal speed with default settings. Default setting is “some” configuration for a hypothetical environment, and for “some” concept of interconnection.

How is the Audience connected to the Connectmox? Wired or wireless? Audience has 2 separate 5 GHz radio’s, which one are you using?

Don’t rely on the “auto” settings of wifi, but be specific in what you choose, after checking freq usage in your environment.

I set ConnectBox in modem mode and Audience is wired connection to CB.
I don’t know which 5GHz radio I’m using…
I connect 5Ghz WiFi to Audience.

If you are just using default setting, you are most probably using 5G1, and it’s managed by CAPsMAN, 5G1 is slower + CAPsMAN is slower, result in much slower is reasonable. Set the wlan3 to AP bridge, set basic rate to 12mbps and 24mbps, supported rate from 12bmps to 54mbps and connect to it, you will get a better result.

Ok but I need do mesh WiFi later so I must use capsman… two Audience later…

6

Why would CAPsMAN produce slower speeds?

7

CAPsMAN lags just a few configuration possibilities, but it works great (at least, that is my experience).

I really want to like MikroTik WiFi, but I’m regularly disappointed.

I realize I can’t compare a $200 MikroTik to a $600 Ruckus, but why does
Mikrotik Advertise unrealistic specifications.

The Audience 5Ghz QCA9984 Radio is rated at 1733Mbs (I don’t think half of that can be attained in a vacuum).

The best I can get out of it is ~540Mbs (running RouterOS version 6.46.6).

I think the cAP AC offers the best bang for the buck. I can get over 300Mbs on a $70 device
that can also work under CAPsMAN.

I really wish Mikrotik would produce some better WiFi gear for indoor APs.

What client device are you using for this test? Is it 2x2 or 3x3?

10

I cannot imagine a reason why you MUST use Capsman.
By the way: having “local” packet delivery does not send your data to CapsMan first.
But again, you can set things up without Capsman.
If you use wireless mesh (or repeater or WDS) you will dedicate at least half of the air-time to that backhaul interconnect.

11

Not sure, I suspect they are using 2048 in AMSDU, I got the exactly same speed by setting it to 2048 in wireless interface.

My speed test with Audience 5GHz
Wlan = 470mbps
CAPsMAN = 405mbps
Wlan+AMSDU 2048 = 405mbps

Please learn to read those commercial specs that everyone, every brand, uses. They are the aggregated throughput , the sum of all interfaces at once (what you cannot use with one client device) , and at the highest MCS rates and at the highest number of spatial streams, with max bandwidth (no interference, no other wifi above -96 dBm) . This means very close to the AP (high signal/nose ratio) , and a very capable client (number of spatial streams is usually limited to 2 however), without neighborgs or other own devices.

Look in the wireless “registration” tab. You will find which WLAN but also signal strength send/receive, CCQ, and current interface rates. (add the needed columns or use “detail mode”)

14

I feel You pain and I’m with You. I don’t know how they test their products (if at all), but in real life Mikrotik wifi performance is low, no matter what settings are used. Someone could sue them…

15

I’m using MacBook Pro with 3x3. As I said I don’t want to be unfair to compare it to a Ruckus R710, but
I’m simply using claims by MikroTik specs.

I also created this chart a while back when first disappointed by RB4011 WiFi performance.
It seems newer software or hardware is limiting USA to zero DFS channels, when in the past
I was able to use the legal DFS channels here. In the past, we could choose “United States” or “United States 3”.
Now it appears limited to “United States 3”.

16

If that is really the reason, why doesn’t mikrotik “fix” it?

17

I’m just guessing maybe this causes the problem, so I did email them and their answer is they will add the option for AMSDU in CAPsMAN in future, but not sure when.

“Audience should have the best coverage, also the design is more upright and from personal experience, covers really large areas.”

But If the best device is acting so bad and needs also tuning, to get it somehow work at all, then this is insane.

“I’m using MacBook Pro with 3x3. As I said I don’t want to be unfair to compare it to a Ruckus R710, but

  1. Check in “registration” tab in “wireless” what your interface connection is. E;G.“1300Mbps/80MHz/3s/sgi” is the best you can find there. (The Mac-book is 3x3, not 4x4. 4x4 is required for 1733Mbps)
  2. Throughput (data rate) is estimated at 60% of the interface rate. 802.11 has quite some overhead! So the best datarate to expect here is 780 Mbps.
  3. You only get 405 Mbps. Check the numbers in “registration” first. There the value might be e.g. “650Mps/80MHz/2s/sgi” (only 2s dual stream, and MCS07 encoding.), at least it will tell by what phenomenon you are not getting that ultimate max speed. (256QAM or MCS08-MCS09 needs a very strong and clean signal)

A ruckus R710 is a pretty dated unit. An R510 or R610 is newer and I would take a R610 over the R710 anyday.

Now lets also skip the B–L$h!+. Ruckus has been on Promo for nearly 2 years. The $650 R510 is readily available on Amazon for ~$250. AND STOMPS ALL OVER THE AUDIENCE.
