5g WiFi is slow - cAP ac

RouterOS Wireless Networking
1

Hello,

My friend helps me to configure two of my cAP ac devices. One in my flat and second is in cellar.

First of all I’ve updated Firmware to: 6.48.3 on both of these devices.

We’ve setup following SSIDs networks:
1 x 5g local wifi network
1 x 2g local
1 x 2g Guest

I can say that this 5g is working really horrible slowly.
Both of my laptops are showing me, that signal strength is best ( 866.7 Mbps ). But When I tried to test the real download at my home 1Gps network, I can see speeds approx: 150 - 300mbs, I’ve expected speed somewhere over the 300Mbps. My Wish is to see 400 - 700…
On My previous AP ( ASUS ) my 5g WiFi gave me 400 - 800Mbps…

Now both cAP ac devices are onfigured via CAPsMAN from of my home CRS router-board (CRS125-24G-1S-2HnD),

here is my config:

/caps-man channel

Can you check if I’ve overlooked something to speed up my 5g WiFi?

Looking forward for some solution.

Well I just happened to experiment with my CAPAC the other day…
Speed test using OOKLA to my ISP provider and back through their network (out bell canada, back via bell aliant - 1gig connection)

Iphone 12 mini.
Capac LOS within 10 feet
using 5 N/AC 20/40 Ce
Down 195, Up 150
freq 5540

Using 5 AC 20/40 Ce
Down 256, Up 187
freq 5540

Using 5 AC 20/40/80 Ceee
Down 344, Up 275
freq 5500

Quite impressed that on my small phone i could get 344 / 275 on the capac!!

MIkrotik devices are pure lottery, identical hardware/configuration which works for some, doesn’t works for other, including me (I have same device). Changing working (Asus) setup to Mikrotik is pure masochism, so take it as a (bad) experience and either switch to better solution or just to live with it. :slight_smile:

4

This is not going to happen, best case scenario with mikrotik 2x2 ac on 80Mhz channel is 300-400 Mbps.

5

With my TP Link eap245 and 660hd, you will see higher throughput for LOS.

6

@anav - I’m really curious if triple chain would help performance of MikroTik 5Ghz vs say TP-Link EAP245. I think the MikroTik cAP AC is more suited to be compared against the Tp-link eap-225..

I’m wanting someone to test the “older” MikroTik Hap AC [has triple chains…] vs the newer cAP AC and wAP AC units. Essentially all the newer ARM based based MikroTik products are only dual chain 2x2. Exception is the Audience device – you can re-configure it to use the other 5Ghz card which has 4x5ghz.

7

If you guys need fast Mikrotik WiFi just get a device like hAP ac3 or the Audience which are compatible with the new wave 2 drivers (which are actually developed by Qualcomm).

However I’m waiting for their WiFi 6 lineup to replace my hAP ac2 at home since I’ve got new WiFi 6 capable devices.

I know I can just go and buy separate WiFi 6 AP from another vendor but Mikrotik hardware quality is so good for its price tag, I’ve had more expensive routers from well known consumer brands like TP-link, Netgear and Tenda but they all went bad after more than a year of service (dead 5GHz, dead ports etc).

8

RB4011 has 4x4 too.

9

Ditto this!! 100% agree with you. hAP ac3 is great product, wave2 support but unfortunately is only 2x2 device. The audience is great, I’ve been emailing MikroTik asking they release another Audience base-station unit with more ethernet ports. Audience supports wave2 and can be “4x4” if you manually configure the additional 5Ghz radio/card that.

RB4011 is an option as it is 4x4, but there were teething issues with that device and ultimately best to just have regular RB4011 router and a dedicated AP.

10

If I could caps-man it from my hAP AC2… i would give it a try but from what i understand… WiFi5 MU-MIMO is supported in ROS7 which does NOT work with caps-man???

11

No, the wave2 drivers with MU-MIMO are not compatible with either the hAP AC2 or the Cap AC because those are 128MB RAM devices and wave2 requires minimum 256MB RAM.

The only way to get MU-MIMO on the AC2 is by installing OpenWrt but WAN port VLAN tagging is currently broken on IPQ401X devices, however if you don’t need VLANs you can give it a try.

12

Sorry… I have an Audience that I am using as a cap.

I want to run caps-man on my hAP AC2.

I want the Audience to be a cap with all 3 radios available for client devices.

13

I have Caps-man on RB4011 (Ros 6.47.10) and i can control without problem the wifi on Chateau with ROS 7.

14

But only with the standard wifi drivers, not with wifi-wave2 drivers.

15

Even with local forwarding turned on?

I gave up on caps-forwarding a while ago as it really slowed things down. So I always use local forwarding and client to client forwarding.

Thing is when I put a few devices on my Mikrotik WAPs they slow down really quick. So I get frustrated and flip back to Ruckus or Cambium and get 2 and 3 times better throughput.

A run of bad firmware on Ruckus opened the door to looking at caps-man again.

But as I beat to death… MU-MIMO and Wifi5 standards ratified in 2016 are still not fully supported… In 2021. Well except maybe in development branches.

WiFi6? Yeah right

16

Under capsman that speed is normal, around 300-400mbps on 80mhz channel. Whitout capsman you can get a bit more, around 500mbps peak.

17

Been running the Audience as a 3 AP wap for the last few days.

After I installed RouterOS7… Caps man could control it.

As soon as I out in the wifiWav2 package… I couldn’t

Had to default the unit as I got a few problems.

After default… Unit came up like a CCR… No real config other than an IP address. Didn’t look into that further.

Configured the 3 radios.
Can’t seem to figure out how to add a VLAN to an SSID/VAP.
Adding a VAP caused the interface go get stuck on selecting channel.

But… On the bright side…
The unit carries 25 clients with ease and better throughput that I had with Router OS. I get speed tests in the 400s here and there now. Under the same load, the unit used to top out in the high 200s.

I have 20 nos of cAP ac RBcAPGi-5acD2nD, connected with CAPSMAN (951G) without using CAPSMAN it’s speed goes to it’s high range but when I goes with CAPSMAN speed limited with around 7-8 Mbps. can anyone help to resolve my issue ?
