Unfortunately I have an issue with my new router (pretty much the same as this topic: viewtopic.php?t=192727). My HAP AX3 performance is very unsatisfactory - regarding download and upload speed (via iPerf3 TCP) it is pretty much the same as HAP AC2 (about 200-300 Mbps), that is worse than my primary router HAP AC3 with wifiwave2. I used multiple ax devices for testing - Galaxy S20+, Galaxy Tab S8, iPhone 12 Pro and Thinkpad E14 with some mediatek WiFi chip - each of these devices were using Wifi ax and 2 chains. Best results were obtained via laptop (about 400 Mbps). All other devices were having troubles reaching 300 Mbps. I tried every possible version of Router OS and different configurations (i.e no country settings for highest transmit power, UNII 3 frequencies etc.) but nothing helped. That is realy bad considering this is an AX device - such speeds (and even much higher speeds at 5xx Mbps) can be achieved with old AC devices from competition's devices...
An interesting fact is that, upload speeds using Speedtest.net (I have 1 gbps ISP connection) are noticeably better at roughly 7xx Mbps, whereas download speeds are about the same as iperf3 results. Neverheless, I upgraded to HAP AX3 solely for the reason to get higher wifi speeds (I was hoping for 700+ Mbps) as some users reported they were getting. However the speeds are pretty much the same as my old HAP AC2 used as an AP.
Is there a hope for an improvement with newer RouterOS releases or some sort of immediate fix? Or is it some sort of HW limitation like in HAP AC2 case (custom drivers, low ROM)...?
I'm really considering returning Mikrotik and going fo Unifi 6 Lite/Pro to get the desired speeds, but I'd like to get Mikrotik one more chance...
Thanks
Re: HAP AX3 - low throughput
Hi, use latest ROS 7.8 only and play with settings...few meters from router you should get 800 Mbps. Your settings must be wrong..they may get 700 but very close to the router...
Re: HAP AX3 - low throughput
There is a few different threads on AX3 performance.
Interestingly if you run iperf3 test with udp you will get full speed
For me,
iperf3 over tcp: 160mbps down 280 up
iperf3 over udp: 1005mbps down 1010 up
fast.com 1010 (tls over tcp)
smb file copy: 160mbps down 280 up
scp file copy: 160mbps down 280 up
Definitely something odd going on especially since tls seems immune to the issues presented by regular tcp connections, My only advice is to consider opening a support case, as that's the only way things like this can get fixed.
Edit: Adding an observation I just had this morning.
In tests above, I had AX3 connected by eth1 to mikrotik sfp+ @2.5gb link to a CSR317. Moving to eth2 @ 1gb had same results, however moving off the CSR317 to a CSR328 no longer using SFP+, I get 300mbps bi directional on iperf3 tcp run, still not as fast as udp or fast.com but interesting how that made an improvement.

Re: HAP AX3 - low throughput
Well, I tried reconfiguring the router from scratch as well as using Quickset options (Home Dual AP), downgrading to older Router OS releases, etc., but the troughput is always the same. Realisticaly speaking ~300-400 Mbps using Wi-Fi 6 (ax) devices. Transfer speeds using SMB results in ~40-45 MB/s which corresponds to iperf3 speeds... Interestingly enough, pretty much the same speeds are obtained using older Wi-Fi 5 (ac) devices...
Well, your speeds are downright terrible - this is what I was getting in the first months of using HAP AC2 (now it is somewhat better). I will try iperf3 with UDP (just out of curiosity as I already decided to return the item and buy something else...) to see, if I can saturate my 1 Gbps link this way over wireless...There is a few different threads on AX3 performance.
Interestingly...
Re: HAP AX3 - low throughput
I have the same issues on two different ax3 devices.
There is something strange happening recently with ax3. Traffic from Wi-Fi to eth2-4 is bad, traffic to eth1 seems to be better. Also multithreaded iperf, like tcp, 8 streams can load Wi-Fi better than 1 stream.
I think they will fix it one day. Right now we are all beta testers

Re: HAP AX3 - low throughput
Hi Normis!More info needed. Post your full config.
Here is my current conf.
What is interesting, recently, on the 'new' ax3, I have a wifi1 channel override by the system:
changed intended channel to 5280/ax/eCee
Strange, I can't recall such actions on my previous ax3 and 7.6/7.7

Re: HAP AX3 - low throughput
It would be important to check the signal strength and what wireless rates are reported while actively testing the connection, alongside what throughput you see. The changed intended channel is due to detected radar, so a different frequency was selected.
In addition, we would recommend you perform the test with 7.9rc, instead of 7.8 stable.
I'd also recommend making sure that hardware offloading is disabled, and checking if different frequencies produce better results.

Re: HAP AX3 - low throughput
I would echo guntis on using 7.9rc2, 7.8 should be renamed 7.8 gremlins (vice 7.8 stable). I had a devil of a problem trying to troubleshoot wireguard between two MT routers until I said okay EFF IT, going to upgrade both to 7.9rc2, bingo started working. I have read of other functionality not working on 7.8 but working when downgraded to 7.7 or now upgrading to 7.9rc2.
Re: HAP AX3 - low throughput
Hi Guntis,
It was tested also on 7.9rc2, which is the version I’m currently using, you can see it on the first line of the config.
My recent test: 2 meters from AP: public Internet speed test: 790Mbps average, iperf3 on eth, tcp, 600Mbps. Iperf wired 890Mbps
I will check the offload and other freq, still it acts strangely.
BR,
Piotr

Re: HAP AX3 - low throughput
With 1 802.11ax client connected with 2x2:2 to one 802.11ax access point with 80 MHz you should get around stable 800 Mbit/s if it is sitting right next to the access point.
Re: HAP AX3 - low throughput
I've been doing some additional configuring and testing, and yet nothing seems to have improved the speed whatsoever. I used various frequencies (I'm even lucky enough to have most of the 5 GHz band "free", so no other AP should cause an inteference), locations of the AP and devices, but no luck. The (download) speed is always around 200-400 Mbps (the best result I obtained was about 450 Mbps using my WiFi ax laptop) using iperf3, SMB transfer and Speedtest.net. Testing via Speedtest.net sometimes shows much better upload speeds (reaching 700-800 Mbps) but it seems to be unrealistic as iperf3 and transferring files using SMB indicates the speed is always below 300 Mbps (using smartphones/tablets) and below 450 Mbps using laptop.More info needed. Post your full config.
Moreover, I noticed, the Wi-Fi signal strength seems to be an issue, at least when using correct country settings (= Czechia) - 2 meters away from my AP (directly in front of it with no obstacles), I get about -60 dbm using 5 GHz. This might be the reason why I have a rather low theroretical troughput (link speed) - usually about 600-800 Mbps when using devices in the same room. I get 1,2 Gbps only when I'm few centimetres from the AP, and yet even then the speed is the same. With no country set, the Wi-Fi strength seems to be better, but the speed is still the same.

That's what I'd like to get, and some people claim they reach such speed with Hap AX2/AX3, and yet the rest of us (I'm definitely not alone) have troubles reaching even half of the speed...With 1 802.11ax client connected with 2x2:2 to one 802.11ax access point with 80 MHz you should get around stable 800 Mbit/s if it is sitting right next to the access point.
Re: HAP AX3 - low throughput
Hello asblitz,
It may have nothing to do with your problem, but this seems strange to me:
Secondly because if it's the real channel 1, then it's on the 2,4Ghz band and not the 5Ghz, like in your config.
I would also try using 5180 frequency instead of such high one, as the allowed power on such frequency is limited on ETSI domain (SRD devices less than 25mw).
Best regards,

Check your antenna, is the connector installed tight?
I've noticed that the MikroTik antenna acts strangely. It is not exactly the same performance on both sides of flat stick. Sometimes when you rotate it 180 deg (the side of the stick, not the position of it), it can perform better.
It is another pain. It looks like the characteristic is not nicely oval but different.
You can also check your CPU temperature. It should be below 60 deg unless you have it in a hot cabinet.

I have the same problems. The wifi has a very bad performance compared to other cheaper routers. Less range and less speed. I have tried to change all possible parameters but nothing works. In my case it works the same with version 7.6 and 7.8
Re: HAP AX3 - low throughput
You can try to test it on 7.9rc3 plus play with freq, I'd keep it default as it seems to be working better on 7.9, it was terrible on 7.6/7.7I have the same problems.

Re: HAP AX3 - low throughput
Looking at the AX3 WiFi performance only, I suggest staying away from it and going for a different vendor.
It is bad, and I'm afraid it will not get better
It is a pity that they are running away from this topic and not acknowledging issues.
Hard to say is it a bad design, poor quality or maybe issues with coding wireless chip from a new vendor? I'm naive hoping it is a SW issue and there will be a fix one day.
I could get a refund, but I stayed with it just because of the great performance with containers and RouterOS flexibility.
When I need WiFi performance, I turn on WiFi on my cable modem...

Re: HAP AX3 - low throughput
I agree Peter, in that its disgusting that the cablemodem provider gave you a better wifi product (which I am sure you received way before your AX3 ) then the latest newest wifi home router MT has provided. They should be ashamed.

Do you own ax3?I agree Peter, in that its disgusting that the cablemodem provider gave you a better wifi product (which I am sure you received way before your AX3 ) then the latest newest wifi home router MT has provided. They should be ashamed.
Re: HAP AX3 - low throughput
My experience also similar and i already explained all these in another long running thread about wifi performance issue. After lots of trial and error, finally support told me to change the location of the ax3 I cannot change the location as that is my fiber landing point and from the same location ISP router gives double the speed in AC band.
Finally moved to Tenda i29 access point and happy now.

It is important to highlight for potential users: hAP ax3 has low wireless performance compared to ax or even good ac routers. If you want Wi-Fi performance - stay away from ax3.

Re: HAP AX3 - low throughput
I had to replace my two ax2 and turn off wifi on ax3.
They are replaced with two Ubiquiti U6 Lite AP.
No more random dropouts, my laptop actually connects to 5 GHz and with full speed (same laptop on ax2 always connected to 2.4GHz), my gateway for central heating system works again, roaming is much better. (Eg. When i go upstairs my phone connects to upstairs AP, while with ax2 it always stayed connected to downstairs ax2 until i disable/enable wifi on my phone).
Range is something different, outside the house, ax2 dropped like 2 meters from front door. With U6 Lite (smallest AP) i have wifi at my garage. (You have like 15 meters and 3 brick walls between)
I really like mikrotiks products and we use a lot of LTE routers at work and we even had cap ac as our AP and it worked great but i must say that i wanted for ax2 to be great AP and i tried to make it work but wifi was just unusable...
In my opinion, cap ac was, at least for me, a much stable device. And i was forced to use other AP instead of mikrotik.

Re: HAP AX3 - low throughput
Hello there,More info needed. Post your full config.
Regarding radio, even with full auto 5Ghz frequency setup (empty), by default AP performs low. The only moment it improves is when it jumps to a lower part of freq and prints red notice above wifi interface: changed intended channel to 5320/ax/eeeC
It brings hope, that you will fix it one day
Regarding eth: I've found one issue which can cause lower wifi to eth traffic:
When I'm running iperf from WiFi to Eth5, I have more traffic on wifi, around 600Mbps and no errors, and a bit lower traffic on Eth5 GE port, with increasing Tx Queue Drops
What is also interesting is that from time to time, traffic hits 1Gbps on FE5. It is impossible to load 1Gbps from my ac wifi@600Mbps client.
It looks like some strange issue with ethernet frames switching or L3 packet routing.
On uplink FE1, which runs at 2.5Gbps I also see TX Queue Drops and traffic peaks.
If you want me to disable some HW offload feature, can you provide a terminal command?
Re: HAP AX3 - low throughput
yes, capacs, and ax3 and tplink eap245/660HD/615 ( and various older other vendor wifi routers )
Re: HAP AX3 - low throughput
Hi, I'm experiencing quite frequent disconnections from the Wi-Fi network especially iOS devices (Wi-Fi 6). According to the log, the reason for disconnection is loss of connection. This happens mainly when the devices have their display turned off and are not in use. This shouldn't be normal behavior, right?
Any ideas on how to solve this problem? I'm using the default config for Wi-Fi and only changed the region to Czech Republic. I use the same ssid for 2.4 GHz and 5 GHz network.
Running 7.9 rc5

Re: HAP AX3 - low throughput
Looks like a client issue.
If the client disables wifi when the screen goes off, what would you think the access point can do about that apart from logging it gets disconnected ??

Re: HAP AX3 - low throughput
facing same issue range is not good my ISP basic huawei router range and speed is better than this router
Re: HAP AX3 - low throughput
Have you found out anything new about this? I noticed the same, TLS over TCP gives me 1gbit, everything else around 300mbitThere is a few different threads on AX3 performance.
Interestingly if you run iperf3 test with udp you will get full speed
For me,
iperf3 over tcp: 160mbps down 280 up
iperf3 over udp: 1005mbps down 1010 up
fast.com 1010 (tls over tcp)
smb file copy: 160mbps down 280 up
scp file copy: 160mbps down 280 up
Definitely something odd going on especially since tls seems immune to the issues presented by regular tcp connections, My only advice is to consider opening a support case, as that's the only way things like this can get fixed.
Edit: Adding an observation I just had this morning.
In tests above, I had AX3 connected by eth1 to mikrotik sfp+ @2.5gb link to a CSR317. Moving to eth2 @ 1gb had same results, however moving off the CSR317 to a CSR328 no longer using SFP+, I get 300mbps bi directional on iperf3 tcp run, still not as fast as udp or fast.com but interesting how that made an improvement.
Re: HAP AX3 - low throughput
What are those with issues seeing for tx-power when running below command?
Code: Select all
/interface/wifi/monitor 0,1
Re: HAP AX3 - low throughput
Reason I ask above is using the below configuration on a hAP ax2:
I get the below tx-power set: 15 for 2.4 GHz channel 1 and 9 for 5GHz channel 149.
Looking at Mikrotik's own reg-info output for Australia below, there is clearly a bug in applying channel.frequency=5745 since reg-info states 36 as max power. On hAP ax2 this translates to max possible tx-power of 26, but I am getting 9.
Also, 2.4 GHz band has a reg-info limit of 20 so the tx-power of 15 I am getting for channel 1 appears correct. However this reg-info limit is actually incorrect according to latest Australian legislation. Wifi 2.4GHz band limits are defined in item 59 here https://www.legislation.gov.au/F2015L01438/latest/text and as you can see should be 4W or 36 dBm.
I would be happy to be proved wrong any of this, but my basic claim is tx-power is bugged on some 5 GHz channels in some countries and also that reg-info is out of date/incorrect for some countries (I have checked a few other that seem to have incorrect reg-info, eg Hong Kong). Both of these can combine to severely limit the range you will get. To confirm if this is what is causing an issue for you check your tx-power.
Code: Select all
/interface wifi set wifi1 configuration.country=Australia channel.frequency=5745
/interface wifi set wifi2 configuration.country=Australia channel=1
I get the below tx-power set: 15 for 2.4 GHz channel 1 and 9 for 5GHz channel 149.
