Re: hAP AC2+cAP AC Roaming is a joke

I hope in new ROSv7 have a lot of improvements, optimization and other protocol aviability in wireless part ! The Roaming works well, but only for reconnecting to device with strongest signal like 802.11k ! Lol, 802.11ax is on the way, and Mk still has this buggy non-certified mess instead 802.11ac...

Re: MU-MIMO?

in the 6.41rc there's a new feature !) wireless - new driver with initial support for 160 and 80+80 MHz channel width; and indeed MT will have its first wave2 device, the next gen cAP with IPQ4018 (https://www.qualcomm.com/products/ipq4018) that has mu-mimo support in hw. the device received FCC ap...

Re: wAP ac / cAP ac: no 2 streams with 80MHz?

wAP AC - no described issues here.

P.S. multiple stream won't give you much though - it's the weak side of Mk

Re: Mikrotik WLAN & CAPsMAN - Bad download perfomance

Ok, so I was wrong and it was unfair to say "MIMO doesn't work", etc, etc... MIMO works! I've made couple of IRL tests (not iperf) - so far, even 3x3:3 makes sense. And note that AC68 is not in the best position - bandwith rate is around 877-1300mbps, jumping around due to close distance - adapter i...

Re: Mikrotik WLAN & CAPsMAN - Spatial stream perfomance issue

Due to latency at various internal points (wireless microprocessor, kernel scheduler, hardware interrupts), the wAP ac processor is a limiting factor here. As the MIPSBE SoC is older and cost-optimised, some of the internal datapaths may be a bit limited too. You'd be in much better position with a...

Re: Mikrotik WLAN & CAPsMAN - Spatial stream perfomance issue

I guess, it's just poor 5GHz wireless support from MT and CPU limitations - things I somewhat forget and kept knocking wall with my head.

Re: RB4011 wireless performance?

At this moment bad, we tested 3 Intel Based AC Laptops and both are only able to connect to 54 MBit..... Kind of seems "par" for Mikrotik with wireless devices. They release them and it takes several months and routerOS/firmwares before they start showing acceptable results. I went through that wit...

Re: Mikrotik wireless LAN - WiFi - MIMO not working

Still get 0 improvement with 3 spatial streams, 3 chains working between wAP AC client and Asus AC68 unit. To have MIMO (multiple spatial streams) working, those streams have to be well separated (radio-wise) from each other. A great separation technique is use of two orthogonal polarizations (if u...

Re: Mikrotik wireless LAN - WiFi - MIMO not working

The wAP AC CPU is likely maxing out at that bandwidth. Getting ~500Mbps with multi-stream iperf3 means all WiFi technologies are kicking in, i.e. they are working. What R1CH says may be the truth, sadly... Can you start profiling on the wAP AC and see how much the CPU gets loaded during iperf? Hey ...

Re: Mikrotik wireless LAN - WiFi - MIMO not working

Well, it's not rate issue or MIMO issue - Viesturs reminded me about multi-stream option in iperf - at least benchmark gives out 500mbps when using 3 or more streams. 2.png Max result was somthing about 500-530 mbps. On the other hand, I've managed - with a little tweaks - rise rates up to MCS9-80Mh...

Re: Mikrotik wireless LAN - WiFi - MIMO not working

Yes, you're totally running @ 1 spatial stream, i.e. 1 chain. Also, you're not wanting too much of your HW, you're just wanting what you paid for, which according to MT's own page is 1300 (or 900Mbps if you consider the real life). What you get is a far cry from the advertised speeds... Check this ...

Re: Mikrotik wireless LAN - WiFi - MIMO not working

Hi RobCo, I really feel your pain, I do. Although I'm not convinced my post will help you, it may spark some insight in you. 1st thing - are you sure your clients are actually WIRED with 2 separate antennae? 2nd thing - for MIMO to work well one needs a good spatial separation for all spatial strea...

Re: CAPsMAN poor wireless speed

So MIMO is broken in some way that prevent any speed gain from additional chains? Interesting observation, let's hope that this is reproducible and fixable by mikrotik. Yeah, seems like it. Furthermore, as I mentioned before (here or in support ticket?), MIMO seems to be broken broad - "at all" - i...

Re: CAPsMAN poor wireless speed

Ok, so I've checked streams, leaving 1 stream per test phase - so far, I've managed to discover it IS streams issue. Thus, when leaving only 1 chain activated and 1 stream flow, I get the same 30 MB/s - 270mbps. So wireless perfomance is stucked at this point no matter what - whether I turn on all c...

Re: CAPsMAN poor wireless speed

Looking at your first screen shot in your first post, I'd say that's a decent connection. You're connected at VHT MCS 7 with two spatial streams and short guard interval resulting in 650MBps connection rate at 80MHz. Keeping in mind that actual real-life throughput is roughly 50...65% of the w/l co...

Personally, I get > 100Mbps using wAP AC + RB3011 running CAPsMAN, local forwarding. How crowded is the wireless around your place? Are APs locked to CAPsMAN and using encryption?

Re: CAPsMAN poor wireless speed

Have you tried local forwarding vs capsman forwarding to see if there's a difference? Of course I did - and the matter of fact - I ALWAYS use local forwarding enabled, cause capsman forwarding gives me like 10% of wireless perfomance. I've tried disabling other CAPs, both 2.4 and 5, I've tried remo...

Re: CAPsMAN poor wireless speed

I suggest my speed from these factors: 1) Both Tx and Rx have 2 chains working simultaneously in 2 streams - thus making 866 mbps real. wAP AC and Realtek 8822BE - you can find specs for both. 2x2:2, what can go wrong? 2) Since mikrotik admit their wireless protocols far from ideal, thus output is a...

The problem is - and I don't really have any idea what causes it - wireless speed is cut roughly by HALF from what it is supposed to be. The picture is: NAS - gigabit > Mikrotik CSS326 - gigabit+PoE > wAP AC - wireless conn 802.11ac 2x2 > PC with realtek 8822BE wireless module. RB3011 is connected t...
