Hi everyone, I’m not an expert but just a geek. I wanted to ask you why my RBWAPG-5HACD2HND AP with 2.4Ghz wi-fi goes at a maximum of 30mpbs while the 5Ghz goes at 180mpbs.
I leave you a screen of the network configuration 2.4
You can set 20/40MHz eC channel for double the speed.
I set as u said but Max speed is 35mbps
Change frequency to the LEAST occupied one.
I can get close to 100Mb on 2.4GHz IF you make sure nobody else is on the used frequency (which is rarely the case using that band).
And set your country correct.
What is the client device? What is the values in registration table?
I used speedtest
as you can see from the post I used the least used frequency but by running the speedtest I always get to 30mpbs
Chart is clipped off at 30Mbps, text under it says that max was 42Mbps. So did your speedtest result also came back at 30Mbps? Are you sure there isn’t sone other bottleneck beyond wifi interface? Try testing by using wired connection via the other ethernet port of your wAP.
If it’s correct what you wrote in opening post about 180Mbps over 5GHz, then the most likely explanation is either interference on 2.4GHz band (“least used channel” is not good enough, it has to be pretty empty) or misconfiguration (e.g. allowing to use legacy encryption, such as WPA/TKIP).
Also: you have “manual Tx power” mode set … what is then Tx power setting? Usually this kind of hokus-pokus is not necessary, it’s fine to leave Tx power to automatic.
export configuration and paste it here please.

I tried setting the tx power to superchannel and it improved slightly, I went to 55 mbps.
- You’re running ROS 6.x, so better use “/export hide-sensitive” and remove serial-number or other sensitive information please.
- Please upgrade to latest ROS 6.49.15
- improve basic settings
/interface wireless set [ find default-name=wlan1 ] band=2ghz-onlyn country=italy frequency-mode=regulatory-domain station-roaming=disabled wireless-protocol=802.11
- according to your freq. usage screenshot: channel 2422 is bad. has > 50% usage. 2442/2457 way better.
/interface wireless set [ find default-name=wlan1 ] frequency=2442
- but first try frequency auto selection instead of fixed frequency:
/interface wireless set [ find default-name=wlan1 ] frequency=auto
- best to use this channel width:
/interface wireless set [ find default-name=wlan1 ] channel-width=20/40mhz-XX
- if that overlaps with other channels, try to use 20mhz channel width instead:
/interface wireless set [ find default-name=wlan1 ] channel-width=20mhz
- I assume you use this device indoors:
/interface wireless set [ find default-name=wlan1 ] installation=indoor
Good luck!
Hi, I tried some suggestions you gave me and it actually brought some improvements. Speedtest increased from 29mpbs to 45.

May I ask you if you can also kindly give me some advice on the PTP?
I have two antennas the same as my access point and they are about 20 meters apart.
Approximately 550mbps arrives in the router while the antennas can only deliver 200mbps.
I await yours. Thank you
Do you have to use wpa on wifi ?
It’s a rather slow security protocol. Try to avoid if you can and only use wpa2.
You still use auto frequency selection. Can be next reboot performance becomes a lot worse.
Try to see which frequency is the least used and set your frequency manually.
Why do you set no country on 5GHz ?
What’s the question about PTP ??
Are those client devices connection to that wAP ?
What type are they ?
For PTP this is che topic http://forum.mikrotik.com/t/poe-limit-to-200mbps/176725/1
Set channel-width=20/40/80mhz-Ceee !
Ok, thank you.
Can u help me with PTP as previous post ? Thanks
If there is interference, wider channel may decrease throughput.
WiFi is CSMA/CA, it means it will stop transmitting if it detects another transmission at just 3 dB above the noise floor.
If the noise floor is at -100 dBm and you get a signal from your neighbor at -97 dBm, your equipment will stop transmitting.
Even if your neighbor does not actively use WiFi, the AP will broadcast beacons 10 times a second, each of which lasts just a few milliseconds, but it’s enough to wreck havoc on TCP connections.
If there are 10 APs on the same frequency, the amount of beacons transmitted is so large that it becomes almost unusable for everyone.
Please try a UDP speed test. I feel that you’d get at least twice the throughput.
