hey guys
Question: Why do the Mik hAP AC3 have such a bad Wi-Fi coverage area?
When I am close to the router it works very well but I move 2 meters away and the signal drops to -90dBm in open spaces. There is some configuration to improve this. Is it a recurring failure of this equipment?
Most likely config.
I used to have 2 to cover a complete house with huge brick walls.
Export config so we can have a look.
Remove serial number, public wan ip,…

Did you power it on without antennas connected? Maybe you burned up the radio.
Before turning it on, I connected the antennas, it was the first thing I did.
Can you export configiration like @holvoetn asked ?
The reason is regulatory, most of the EU users are f..ed and this rotuer will perform almost at half compared to Americans buyers for example.
If I select my country, 2.4ghz runs at 16 tx power and I can barely use my net downstairs ,if I select no country (defaults to USA and 26 tx power) I can have full signal thru entire house and near 100mbit speeds in furthest corners of house (ax compatible client )
Did you search the forums ? User bpwl has posted a trove of tips over the years for fixing such issues. Also, depending on the firmware branch, results may vary. I get much better throughput on the wave2 drivers, but range is better for me with the in-house MT drivers.
Not my experience.
It’s an improvement for me using wave2 on both throughput and range using AX3 vs AC3, going through really tick brick walls.
I haven’t upgraded to MT AX yet at home, but I would expect the newer units to perform better with their native drivers (only option with them anyway).
cAP ax performs really well in my application, Mikrotik made some great improvements regarding ax devices and wifiwave2 drivers. (7.9 was so bad i had to use another vendor for some time)
In combination with capsman you have roaming which is working on all of my devices just fine (android and windows devices so i can’t say it works for apple devices)

That’s not export of config…
Terminal
/export file=anynameyouwish
Besides, I see 5745 as frequency on your 5GHz radio.
AC3 can not go there AFAIK.
That frequency is UNII-3 and only AX can use that band.
5745 work for me on hAp ac3 with ww2 (country = USA)
Double checked on AC3 using legacy wifi and wifiwave2, it doesn’t show here.
Maybe a country specific restriction ?

/interface/wireless/info/hw-info <5G interface> whould show HW capabilities of a particular radio. hAP ac2 (pretty similar wireless hardware as hAP ac3) says “ranges: 4920-5925/5/a,an20,an40,ac20,ac40,ac80”
However, wikipedia channel list lists part of UNII3 as indoor-only in certain regions - USA included (the upper part of 80MHz channel, starting from 5745 MHz), so to use it one would have to set installation=indoor (default is any and I don’t think it actually covers indoor).

“Canada2” … indeed only when you need something very special there …
[admin@hAPac3] > interface wireless info country-info
country: canada2
ranges: 2402-2472/b,g,gn20,gn40(30dBm)

5735-5835/a,an20,an40,ac20,ac40,ac80,ac160,ac80+80(30dBm)/outdoor
That EIRP power level is illegal for Europe (most countries are under ETSI) !!!
But with “canada2” it misses most of the “canada” allowed frequencies.
And client devices which set the region automatically (eg via mobile data or GPS) will not capture that extra frequency in other locations

.
And ‘indoor’ and ‘outdoor’ is always tricky with MT implementation/interpretation
‘outdoor’ frekwencies are allowed for indoor installations (because what emergency or weather service signal will it harm there more than when used outdoor?).
Regulators know ‘indoor only’, and ‘also outdoor’, never seen ‘outdoor only’.
Allowed EIRP Wifi power with WLAN driver is 3 dB lower (non-TPC levels only), than with wifiwave2 (which may use TPC levels)
Answer: Why doesn’t it allow me to change the country on the 5g wifi. Always go to Canada2
