I have a x86 box(with 2 intel i211) with Mikrtok v7(L4) installed. The tx and rx irqs are assigned to 1 cpu on 7.12rc, as a result, the CPU usage is not even distributed to all 4 cores.

There's always a problem when passing between zones with different speeds ... in particular when traffic is passing from faster towards slower speed. The device which spans the two zones has to buffer data and different devices do it with various success. MT seems to be among the worst and it seems...

I have the similar issues observed on Unifi U6 Pros, which has 1Gb eth. My NAS is wired to CRS326 via 10G DAC, and the Unifi APs are connected to CRS326 via CAT6 cables. It can get 1Gbps from any 1Gb eth device in the LAN, but I can only get 400Mbps download speed from my 10G NAS to any wireless dev...

I'm considering replacing my US-8-150W with RB5009UPr to save some rack space. Have you figured it out yet? Is RB5009Upr able to power multiple U6 Pro?

First, the linux kernel under v7 doesn't support route caching, so v7 will be slower in most scenarios. Second, CHR doesn't actually fasttrack traffic (although it indicates the connections to be fasttracked) even on v6, I'd assume x86 to be the same case. Third, when you say "CPU reaches 80% ...

I intended to replace my RB4011 with x86 routers, it's little bit tretched when handling 1000M download. 5009 is way too expensive and out of stock most of the time. I started experimenting with the N3160/dual RTL8111H eth. I installed v7.5 with default router config w/wo fasttrack as the 2nd level ...

I'm suffering from this issue as well on RouterOS v7.1.1. I have RB4011 as capsman and RBwAPG-5HacT2HnD as caps. When uploading occurs, the client freezes. You can reproduce it easily with iperf. I tried clean setup the capsman and caps. It doesn't help. I tried literally every channel/extensional c...

IP>Kid Control Maybe it won't limit to 30 mins per day but it's a start to minimise watch time. This kid control feature does not always work, instead, I can add filter rules and simple queues manually.

I have a 2.5 years old daughter and she is obsessed in iPad's online cartoon app. I promise her to allow her watching iPad for 30min/day. My wife always extends my daughter's iPad time once my little girl begs. So I need to implement this idea in mikrotik. My idea is to set dhcp lease time to 1 min ...

i think you better let capsman manage all your interfacs, push unified configuration and select channels for the first time then fine tune with some wifi surveys software.

make it work first, then setup vlans.

Your approach as for now, is not easy to debug

in my case. I have both iPhone x and iphone xs max, and MacBookpro 2013 late, recently i notice they can't connect to one of the wap acs, which happens to be set to 5805mhz eeec automatically by capsman, country is set to my location and same as the iPhone and Mac, 5805mhz eeec just doesn't work.

With Local forwarding and Fastpath active on bridge?
Only Hardware queue on WiFi Interfaces?

localforwarding will increase 2M/s, with fast forward on, i give up, it should be the limit of wap ac.

and actually i mean 42MB/s, 330Mbps

Thats weird, because I have tested it on 8 different crs326 all running beta20 and it works perfect, traffic shaping also does work, however the rate settings are still weird. and a crs326 if I want to set a user to 250/250M speed, I have to set ingress rate at 400M and Egress Rate at 250M On a CRS...

then You should expect slow speed from 10G to 1G port on the same switch, like 300mbps Still with newest beta? I see higher numbers. I tested my crs326 with s+rj10 with every beta, no improvement and that "fix" - *) crs3xx - improved data transmission between 10G and 1G ports; is due to m...

I get around 960mbit up and Down from the crs326 with 6.44beta20 so no speed issues anymore

crs326 too with s+rj10, without any visual improvement, i tested on every beta, now it's 6.44beta40, do you reset the switch or do something particular?

Do you need to run the traffic locally through manager? The traffic is being tunneled back to the manager hence where the CPU usage is coming from, without tunneling you should get full speed.

Problem description: wAP ac's 5G chip is QCA9880, which is suppose to deliver 70-80M/s data transfer speed with 2 chains(866M) but with capsman's manager forwarding, wAP ac uses up CPU to deliver 42MB/s(330Mbps) to only 1 client. It's weird. The processing should be on capsman, there is no filter ru...
