hAP ax3 - 802.11ax 160MHz ??

Wed Apr 12, 2023 2:52 am

Recently purchased hAP ax3 - trying to set 802.11ax with 160MHz channel width - says "unable to find suitable channel", even if I set channel frequency wide enough for 160MHz...

The more I look into it, the more I'm beginning to think the ax3 doesn't support 160MHz channel width, 802.11ax 80MHz only or less?

Are you sure it is not a regulatory domain issue?
Can you please send through your wireless configuration?

also in Winbox, the GUI doesn't show option for 160MHz.. another reason I'm thinking it's not supported?
[admin] /interface/wifiwave2> export
# RouterOS 7.8
# removed 
I've tried with removing Country as well.
I use frequency 5490-5650, which covers channel 100 to 128.
.
[admin] /interface/wifiwave2> export
# RouterOS 7.8
#removed
Neither config works.

HAP AX3 do not support 160MHz...only 80MHz read specification before buying stuff.....

what spec refers to channel width 80MHz?

nothing I can see explicitly mentions channel width specification/limitation.

Read the specifications of the chipset.
No 160MHz.

Specifications:
Wireless 5 GHz Max data rate 1200 Mbit/s

This tells you all you need to know. There is no 160MHz, since max data rate would be different.
2 Streams 80MHz = 1201Mbit
160MHz = 2402Mbit

The confusion is understandable, you are not alone. One would think with an AX2 as a new available product for WIF6, that the AX3 would add something significant in terms of wifi and not just external antennae, like perhaps 160Mhz, but not the case --> the wifi chipset didnt change being the big clue!!

My issue is how do people get 900 speeds out of the deal............ That makes the rule of thumb more like 2/3 vice 1/3............
1200x2/3 = 900 wifi 6, 1200x1/3= 400 wifi 5 and previous. { based on 1/2 (one way transmission, less losses )

Real world and specs were never on par in the past. However, WiFi 6 offers up to eight streams on 5 GHz with ridiculous theoretical throughput, but even 2x2 and 4x4 devices are reaching max theoretical speeds on 80 MHz according to trustworthy sources (obviously in ideal conditions). Hopefully, MT will offer products with more chains in the future. You do not need 160 MHz to get over gigabit speeds at this point...

Is there any Miktotik product which does support 160MHz?

Audience Supports 160mhz on third radio but this radio is 802.11AC not AX

Thank you! So there is no 160 + AX so far...

ahahah well I just wasted 2hrs trying to get 160MHz working given the drop down in the channel config box allows you to select 160MHz.

I'm glad I found this forum thread!

Dear Normis,
Does new unit L11UG-5HaxD support 160mhz channels? I see it supports 2400mbits on 5Ghz.

That makes the rule of thumb more like 2/3 vice 1/3............
Yes dear @anav. We have been there before. The MT WLAN drivers with their limited aggregation, is causing higher % airtime as inter-transmission gaps. (same waits but very small/short transmissions) This causes the 1/3 rule of thump for 866Mbps, if a MT device is transmitting in that channel. Larger A-MPDU aggregation gives 2/3 for those.

Don't want to be based on rules of thump, as the calculation spreadsheet gives accurate numbers, for each case.
