AC band not vissible

RouterOS Wireless Networking
1

Hey guys.
I have a and probably since I’ve got the AC band is not visible most of the time.

My wi-fi config:

# nov/15/2018 13:39:21 by RouterOS 6.43.4
# software id = EUPZ-AKWW
#
# model = RouterBOARD 962UiGS-5HacT2HnT
# serial number = xxxxxxxxxxxxx
/interface wireless security-profiles
set [ find default=yes ] supplicant-identity=MikroTik
add authentication-types=wpa-psk,wpa2-psk group-ciphers=tkip,aes-ccm \
    management-protection=allowed mode=dynamic-keys name=wpasecurity \
    supplicant-identity=MikroTik unicast-ciphers=tkip,aes-ccm \
    wpa-pre-shared-key=xxxxxxx wpa2-pre-shared-key=xxxxxxx

/interface wireless
set [ find default-name=wlan2 ] band=5ghz-a/n/ac country="new zealand" \
    disabled=no distance=indoors mode=ap-bridge name=wlan1 rate-set=\
    configured security-profile=wpasecurity ssid=Nick wireless-protocol=\
    802.11
set [ find default-name=wlan1 ] band=2ghz-b/g/n country="new zealand" \
    disabled=no distance=indoors frequency=auto mode=ap-bridge name=wlan2 \
    rate-set=configured security-profile=wpasecurity ssid=Nick2 \
    wireless-protocol=802.11

The only way to make it visible is to downgrade to 6.40.6/8 and to change the Channel width to 20/40 Ce or eC. Even then the speed is terrible and it still invisible every now and then.
I tried with reset and netinstall, but still no luck. Any ideas?

use older versions . i dont know why the older versions sometimes works well better than the newest !!!
ihave rb921 it works well with the versions of 6.25 better than the newest 6.42.9 :confused: :confused: :confused:

Hey

Even with an older version it doesn’t work as it supposed to. The speed is terrible (on both bands) and the AC channel is not always visible. And I don’t think I can go any lower than 6.40.6 as my router comes with 6.40 factory software.
Anyway I think the problem is solved now. I was advised to change the Frequency from auto to the first available (5180 in my case).

The only issue I have now is that the upload speed (speedtest.net) is better than the download speed. ~90Mbs upload. vs ~40Mbs download. I have a 100/100 fiber connection. Not a biggie, but still annoying…

My current config:

/interface wireless
set [ find default-name=wlan2 ] band=5ghz-a/n/ac channel-width=20/40/80mhz-Ceee country="new zealand" disabled=no mode=ap-bridge name=wlan1 security-profile=wpasecurity ssid=nick wireless-protocol=802.11
set [ find default-name=wlan1 ] band=2ghz-b/g/n channel-width=20/40mhz-Ce country="new zealand" disabled=no frequency=auto mode=ap-bridge name=wlan2 security-profile=wpasecurity ssid=nick2 wireless-protocol=802.11

If you observe CPU load while downloading at full speed (whatever it is), you’ll likely see CPU loaded to 100%.

Hey mkx! I’ll check this later. So… Is there something I can do about it?

When I tested WiFi on RB951G, I observed that approx 1/3 to 1/2 of CPU time goes to wireless process and I guess there’s nothing to be done about that. For the rest, make sure fasttrack and fastpath are working as far as it goes. My guess, though, is that routerboards with weak CPUsare not capable of achieving max speed in DL.
