CAP ac bad Antenna design?

Fri Feb 09, 2018 6:39 pm

Hi,

today i get the first CAP ac´s from Distribution.
I Start to test.... swap WAP ac to CAP ac,
same destination, same distance , same position of Macbook.
WAP ac:
866 Mbit Brutto Shows -72db
CAP ac:
655 MBit Brutto Shows -84db
Real throughput on CAP ac i did not see more than 30 Mbit
Thats what Mikrotik delivers with Wave 2?
Tested with ROS 6.41.2

wAP ac has 3 chains, cAP ac has two.

866 MBit is 80 MHz, with 2 Streams

3 chains @80Mhz is 1300MBit

At any rate I doubt the macbook has three chains.

Are you able to test a hAP ac2 as well?

Macbooks do have Three chains, btw.

That depends on the model of MacBook. In this case it probably only supports two chains since it operated at 866 Mbps with the wAP AC. If it had three chains it would have instead negotiated 1.3 Gbps or maybe 877 Mbps with lesser signal strength.

But the point of the original post is that the cAP AC appears to have an inferior antenna design. I hope that other units (or even the hAP ac2) do not exhibit this issue, otherwise we'll have to wait for an IPQ-4018 wAP AC.

The new hAPac^2 and cAPac have two chains, since most devices only have 2 chains and the third chain is rarely used.

What about load balancing between chains?What if i have 20 + various devices which have mix of 1 or 2 chains, arent all 3 chains on Mikrotik device used and give better overall throughput?

Wave 2 is supposed to do that. But after some research, I learned that this is easier said than done. MU-MIMO is better with static clients, not so good with moving ones.

Even with reduction in chain count, this shouldn't affect signal strength. The difference between -72 and -84 is quite large. Is the TX power the same? Can you test without any of the cases on?

I will try it without case tomorrow
But I think I could be a wireless driver problem, I see really bad reported signal on Lhg ac, but it modulates with high rates, i will investigate this

wAP and cAP is not a fair comparison, wAP is a waterproof device, designed to also be used outdoors. It has a different antenna design.

Why not design all access points (whether wAP, cAP, or hAP) with similar antenna? There are advantages to having an improved antenna for indoor access points, such as lower access point density or improved client reception. And if the wAP has the best antenna, and the brochure indicates that it can be mounted indoors or outdoors, why not have it be the only access point?

Are there antenna patterns for the devices anywhere so we can see how best to utilize their antenna designs? 10dB difference between products is massive, especially when they are both listed as having 2dB antennas.

im actually very keen on purchasing cap ac........ but mikrotik needs to test this antenna complaint.

in fact, i questioned them about this in my email conversation and they claim that caps ac antenna should be better than wap ac if anything.

after replace cAP lite with cAP AC i must say its shit..for now i cant get more then 60Mbit on 2.4GHz and same speed its on 5GHz.
6.42rc30 works better in some ways, time to time i get 200Mbits this speed its not stable.For no reason slows down in time.

I have similiar experience. Speedtest.net shows ~180mbps gradually settling on ~80mbps or worse; iperf3 shows even less impressive numbers :-)

I did some comparisons between cAP AC and my good old hAP AC.

Test conditions/parameters:

802.11an two chains (My Lenovo T420 laptop doesn't have 802.11ac)
hAP AC was running 6.40.1; cAP AC was running 6.40.6

Both hAP AC and cAP AC were running virtually the same wireless interface settings:

On cAP AC:
set [ find default-name=wlan2 ] band=5ghz-a/n/ac channel-width=20/40/80mhz-Ceee country=lithuania disabled=no distance=indoors frequency=auto mode=ap-bridge rx-chains=0,1 \
    security-profile=profile1 ssid=CAP5 tx-chains=0,1 wireless-protocol=802.11
.

On hAP AC:
set [ find default-name=wlan2 ] adaptive-noise-immunity=ap-and-client-mode band=5ghz-a/n/ac channel-width=20/40/80mhz-Ceee country=lithuania disabled=no frequency=auto \
    mode=ap-bridge security-profile=profile_lukoramu ssid=MTLR wireless-protocol=802.11
.

Both chose the same frequency (5180MHz). I kept only one AP turned on at the same time, so no interference between them.

Thoughts? Ideas?

Maybe it's a compatibility issue?.. Tomorrow I will do the test with a newer laptop, which has an AC card..

P.S. I noticed a big difference in Tx/Rx signals too (see above)

Oh bugger. Just ordered the CAP AC to go with a 3011....
This is to replace a very sketchy consumer grade Netgear ORBI system.
Hoping this is a quick FW fix!

Looking forward to the updates.

Upgrade to 6.42.35 didn't really help in my case. iperf3 TCP traffic just collapses on regular basis. Hw. protection mode settings didn't seem to have any effect.

Eh, will write to support tomorrow. And maybe will do some ethernet-to-ethernet bridging/routing tests before that.

This update fixed latency spikes and slow throughput for me. I did have to recreate the "defconfig" dhcp client on bridgeLocal afterwards but that's all.


EDIT:
this change from a bit earlier might have also helped my case:
*) wireless - improved packet processing on ARM platform devices;

Thanks for the detailed testing @lukoramu. The IPQ4018 platform looks really good so I'm hoping these issues can be resolved with software updates and eventually Wave2 support is added. Please keep us updated!

We used a lot of WAP AC in the house and we were very satisfied with its WIFI. When we tested the CAP AC(tested 6.42rc41), we abandoned the purchase. :( :( :(

We stopped selling to customer too....
Hopefully Mikrotik delivers better driver for Wave 2 Hardware,
until this happens the devices are not sellable.

Sometime no Data Transfer possible, but Client stays connected, speed is really bad if you compare HAPac/WPAac with CAPac
and this could not only be about the 2 chain / 3 chain Hardware difference.

CAPac often is not able to deliver more then 30 Mbit to my clients, WAPac delivers 300Mbit easily
seems like we have to wait for updates.....

Did you try latest RC versions? This is a new device, some improvements were added in latest builds. Also, I suggest you make a new topic with the setup description, we would like to solve it for you.

For all you have trouble with wireless throughput please check if have both chains checked on wifi interfaces.
I found when I configured cAP AC set as follows:
cAP AC.PNG
However, with the two chains checked, the speed is smaller than it should. I hope this will improve in future RouterOS versions.

What happens if you make the changes suggested at viewtopic.php?f=3&t=60636&start=100#p452334? Specifically one user reported that #2 and #4 helped.

The config is no hint for me,
I have 1 on my desk for testing everything, and we swapped our company Wifi to CAP for test (15x WAP to 15 CAP)

Speed as Standalone and in CAPsman is bad
We swapped back to WAP, to get back to working.....

Distance is already set "indoors" and, if I try to set Tx Power to "manual" or "card rates" does not work. Only the "all rates fixed" option seems to work.
I have better performance but only in 2.4GHz if I disable the 5GHz interface.
For 5GHz I have no improvement even if I set Tx Power at 17dBm.
In my test environment I got 200-210 Mbps on the 2.4GHz interface when the 5GHz is turned off and ~ 180MBps when the 5GHz interface is turned on.
On the 5GHz interface we have an average of 110Mbps but fluctuates between 90 and 130 Mbps.
I use a Lenovo ThinkPad notebook at a distance of about 2m and connect at 270-300 Mbps - 40MHz / 2S / SGI.
I suspect that the problem is not with antennas but with package management that crosses the wireless interface.

wap ac - antenna gain 2dB
cap ac - antenna gain 2-2.5dB
signal drop by 8dB is ok? omg
I expected you would have a reply to the ubnt unifi but it seems to be wrong again. Again, I will plan to cover buildings using the Unifi. There is no choice.

Today, we replaced CAP AC with WAP AC at our client company. The same settings, the same location, the same users, everything is normal.

I have 3 cAP AC coming tomorrow to start testing.

The wAP AC has been solid... Slow... But solid. Was really hoping that the cAP AC would be the end of UniF--k for us.

I'm currently testing the hAP ac² and I'm having the same issues as described here with the cAP ac. It uses the same chipset.

TX throughput is under 10 Mbit/s, wAP ac is working fine in the same environment. Client is an Intel AC 8265. RouterOS 6.42rc41 seems to fix the issues with 2.4 Ghz but crashes when I test with 5 Ghz.

Configman and 3x wAP - all great. TX up 100mbit/s depending on the quality signal
This same config in configman and connected only new 3x cAP (tyhsi same metod, vlan for capsman) - Tx under 10mbit/s when -49dB quality.
Not good.

Support whats going one ?

Capsman, wAP and cAP in version 6.41.2 and this same firmware version.
I'm buy full product, and used original current software. This product should not be allowed to sell before specific tests :-|

Try the latest 6.42rc release, Mikrotik have updated the drivers for the ARM platforms.

I often test(6.42rc43) that DOWNLOAD is less than UPLOAD (about 5 meters in distance) on IPHONE 6. Is the TX POWER of CAP AC smaller than IPHONE 6?
What is the cap ac TX POWER?

If compared with WAP AC, the CAP AC coverage is much smaller.

Hi, can MT confirm converage/throughput vs wap ac instead of me making a support ticket ...?

It should be evident from this thread that there are serious issues with CAP AC right now, I would advise not purchasing until stable firmware and RouterOS are released that fixes everything. In theory CAP AC should be about the same performance-wise (or better) as the WAP AC due to the newer high speed IPQ4018 chipset and Wave2 wireless support (even if not yet enabled). It does have one less chain on 5 GHz, but devices that can make use of all three spatial streams are very rare (often only Macbooks).

This is one of the first devices Mikrotik have made using the IPQ4018 so it's expected that there are some issues moving to a completely new platform. I expect they can all be fixed with software as the IPQ4018 is a popular chipset already in use by many other devices such as ASUS and Neatgear consumer routers. The IPQ4018 chipset itself is from 2016 so it should be well-established in terms of hardware and Linux kernel driver support.
