CAP ac bad Antenna design?

mistry7 · 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.

-Chris

866 MBit is 80 MHz, with 2 Streams

3 chains @80Mhz is 1300MBit

AlainCasault · Fri Feb 09, 2018 10:01 pm

At any rate I doubt the macbook has three chains.

Are you able to test a hAP ac2 as well?

mistry7 · Sun Feb 11, 2018 2:14 pm

I will get the first one in the next week

Macbooks do have Three chains, btw.

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.

Mon Feb 12, 2018 3:45 pm

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?

AlainCasault · Mon Feb 12, 2018 4:50 pm

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.

R1CH · Mon Feb 12, 2018 6:14 pm

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?

mistry7 · Mon Feb 12, 2018 7:24 pm

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.

macbook pro models have. mb air is "just" 2chain.

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?

R1CH · Wed Feb 14, 2018 12:18 pm

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.

biatche · Sat Feb 17, 2018 6:23 am

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.

frenky55 · Sat Feb 24, 2018 1:16 am

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)

Sheriff1972 · Mon Feb 26, 2018 12:15 am

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.

biatche · Mon Feb 26, 2018 6:10 pm

Sheriff1972 · Mon Feb 26, 2018 10:19 pm

Hope you are right

lukoramu · Mon Feb 26, 2018 11:34 pm

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!

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.....

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:

However, with the two chains checked, the speed is smaller than it should. I hope this will improve in future RouterOS versions.

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.

hapi · Wed Mar 14, 2018 12:00 pm

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.

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.

biatche · Thu Mar 15, 2018 6:10 pm

can MT confirm these issues instead of being silent? I plan to buy cap ac fast.... but problems must be ironed out first

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

Ok. When upgade cAP to version rc - TX rate looks good.

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.

biatche · Fri Mar 16, 2018 2:13 pm

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

R1CH · Fri Mar 16, 2018 3:23 pm

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.

cAP AC arrived last night. Dropped it right in place where the wAP AC has been sitting for the past week. Updated to CURRENT packages. Set it to Caps-Man, matched the channels to what I had used on the other WAPs. Looks like I am getting an average of 189M using local forwarding.

100M SLOWER than the wAP AC (289M).
220M slower than the UniF--k AC Pro (420M)
400M slower than the Ruckus R510 (605M)
So bummed right now.

I had a load of disconnects / reconnects from a netatmo camera. I then check ked the firmware and realised that I could not update the firmware, or when I did,, it would not stick. I eventually got it accept the latest RC firmware by using the tik app. If you are experiencing disconnects make sure your CAP AC device is actually using the most recent firmware. Once I got this done the disconnect / reconnect issue has gone.

Have you actually tried pushing traffic through it? Most devices won't try to negotiate higher rates until it's needed. Simply associating and looking at speed often provides misleading results.

I didn't see this thread before and was just hungry for the hap ac² and the cap ac by looking at the specs. they arrived yesterday.

for me the signal strength improved a bit on both devices. however, i confirm from my side that the throughput is much slower.

i am not using yet the RC firmware. i have the 6.41.4 running.

I really hope this will be solved very soon. I don't want to be forced to return the devices, since the specs and price were exactly what my wet dreams were about the whole last year.

WebLuke · Mon Apr 23, 2018 7:48 pm

Just updated to 6.42.1 on my set of cAP AC (RouterBOARD cAP Gi-5acD2nD), did a speed test from my Google Pixel 2XL, 92 Mbps Down / 272 Mbps Up, tested on a wired connection to the same site 393.9 Mbps Down / 368 Mbps Up. The Transmit side of the hardware should be great considering its a fixed device, yet my phone is doing better. These results seem to be a little better because I was seeing 70-75 Mbps Down before the update but we should be seeing around 150-300Mbps when connected at a Tx Rate of 200-400Mbps40MHz.

Notes: I sit about 20 Feet from the AP testing, 5Ghz, -50bB Signal, I have chosen a channel that is empty in my office building, CPU never goes above 3%, I have a mix of 2.4 and 5 Ghz clients connected totaling only 8 all phones just doing background data.

jusvir · Wed Apr 25, 2018 8:25 am

Could this all happen because of heating problem? We just bought bunch of CAP Ac:s and noticed that they are really hot. I mean, they all run that hot that they literally smell (burned) electronics and I can't believe that those things will live long this way. Now there's 6.41.4 OS inside them but we are testing others as well. Power is injected with 802.3af switches. CPU load 0-3%. Would it be somekind of transformer/power supply issue?

(duplicate of my post to other related thread, but info is relevant)

hi, i wanted to post my limited wifi testing so far on the cap AC (good).
I bought the unit from amazon a few days ago (most standard MT US sellers are out of stock).

Running latest release, 6.42.3 (updated FW also). Im very impressed so far with my limited tests (and i have other threads on here with my un-impressed 5g ac wifi tests on other home/office RB 5ghz-AC wifi products, like hap AC and ac lite)

Client- iPhone 7+ w iOS 11.3.1
AP- (see export below ) set to auto, the AP choose 5805 eeeC

Speedtests.net app (to our own in-house speedtest server, so all Ethernet/local, no internet)

Same room as AP ( maybe 4ft from the AP, no obstructions):
200-210mbit down / 190mbit Up

1 room over from AP (AP shows client at ~ -61):
170-195mbit down / ~170mbit Up (great, for 2x chains AC!)

"down stairs" from AP (AP shows client at ~ -80):
~70mbit down / 60mbit Up (great for this test spot)

(2ghz was showing great numbers also, but we focus on 5ghz)

Ofcourse this is just one client type, but so far we are quite impressed! (we test/use ALOT of various APs, ubnt, ruckus, cisco , MT. we only use MT routers ofcourse though. ).

(and WOW is that a powerful new CPU in the IPC-4018 based on our quick tests on cpu!)

(i do hope that /int wire Spectral-history / spectral-scan compatibility can be added in the future, as it is unsupported on both cap ac's wlans currently, as is the case with all MT 5g AC radios currently and several 2g radios too, and its an amazingly useful tool when you can use it)

When do you thing will be ready the wave2 support in RouterOS????
Or we need to buy again other new model to get wave2 support?

I know
this has been beaten to death, but wanted to share my experience
bought a CAPac to replace my TP link AC 1750 (wanted wifi in the garden)

I used the included PSU to power RB450GX4 and from there POE to CAPac.

After first reboot I immediately did a simple config to see the beast and was really disappointed. I would loose connection asap I would move 5m from the AP.
I cursed but said ok lets try latest current firmware, same scheiss...Did some random tweaking and rebooted an the thingy wouldn't even turn its Leds on.
Started considering RMA and then I had an odd idea: lets try another patch cable and TADA thingy would reboot and performance was ok(ish).
Range: 5G is less good than TP link but 2G is better
Throughtput: its reasonable / I don't really care
Compatibility: IOS perfect, Dell Laptop (intel NIC) perfect but Minix and Samsung TV only in 2G. Canon camera also 2G (but might not be AC compatible have to check doc)

Haven't investigated yet why Minix and Samsung don't hook on 5G, will do at a later time when I create VLANs and so (one day...maybe...hopefully)

So to conclude on CAPac could have been better but its ... mmmm...ok. I do have connectivity on half the garden now, but probably I will have to order a second one (one day after Vlan) to put in garage to cover the rest of the garden. And most importantly make sure input power is good its such a pity to have a bad experience for a stupid patch cable.
