read a whole lot about the hAP AC in the last few days, but no satisfying answer came up.
I bought two hAP AC to create a wireless bridge, works without a problem.
The routers are 5m apart, just divided by one wall.
I can’t get a connection better than 300mbit (measured with Tools/Bandwith Test), if I try to copy a file from my NAS, can’t get more than 15MB/s. Cable to Cable 90MB/s.
Didn’t expect the same results than cable, but I’m really disappointed with the hAP AC performance.
Tried different settings and different firmware versions.
Really weird was that, if I did a reset without restoring the default config and create it new on both routers, I can get a connection speed of 800mbit, file copy around 35MB/s.
But only for 5 minutes after that it’s back to the speed described above.
here are the configs

I’ve got an international version here I’ve been playing with.
Some DFS channels will not allow 40 and 80MHz wide channels. Not sure what all the rules are to that at the moment. I’m not sure if it is a Mikrotik thing or part of the standards.
I may tinker with a couple of my other brand AC links and see what they do.
Got the device back and tried the NV2 and nstreme protocol. The results are even worse.
Isn’t there a reference wireless config for this kind of thing?
What signal levels are you seeing? What CCQ are you seeing during data transfer? Are there other nearby APs using any frequencies in the range you have selected?
Even one wall can make achieving gigabit speeds difficult. One thing I have found to help is setting amsdu-limit=2048 (instead of the default 8192). (I have a similar setup, hAP ac, one wall, 5m, but connection is to Macbook Pro.) I am able to reach 300 Mbps (35 MiB/s) file transfer speed under best conditions: around -50 dBm signal, 3 m, clear LOS. With conditions like yours (5 m separated by wall) speeds are closer to half that. 5 GHz does not like walls.
yeah maybe, but if I use my “old” netgear r7000 routers, I get around 70-80MB/s and the firmware is crap.
and I would be happy with 35MB/s just expected a little more from 2 Mikrotik hAP ac
here is screenshot during file transfer, did a lot of testing with the settings, but it didn’t change much
The 5m status looks perfect to me, I am also surprised you are not seeing higher throughput in that case. But if there is another AP using that channel, you will not see that reflected in the status.
I am not sure what the wireless regulations are where you are (Berlin?), or for the country you have selected for the link (“australia”, from your earlier post). But 5770/Ceee is an atypical center frequency; usually it’s 5765/eCee or 5745/Ceee (which, according to Wikipedia, is the only legal 80 MHz band in Europe, and is supposed to be limited to 25 mW / 14 dBm). While I would expect the link to work given your settings, I would rule out any other problems or strange interference by switching to 5745/Ceee.
Turning down the power a bit can’t hurt either (tx-power-mode=card-rates tx-power=14). Especially in LOS 1m case, RSSI is way too high. You should have tx-power=0 or even negative in that case. RSSI should be between -45 and -60 dBm.
I don’t think nstreme will help you; stick with 802.11.
just for testing purposes I don’t mind about regulations but I would expect a higher transferrate too
card-rates is not supported but “all rates fixed”, will test further but right now I get a stable 15MB/s with 802.11, not perfect, but acceptable for now
I haven’t tried bridge in a while, but I was able to get around 450Mbps between two hAP ac about a year ago, just using regular 802.11 / no nv2 or nstreme
Enable fast path on the bridge settings. Uncheck use IP firewall on bridge settings.
I’m not sure about the newest beta but I’ve had excellent results out of 6.34.6.
You need to do something to get your signal lower. That -55 is about right. The performance drop with a signal of -25 is expected. That is the tech version of a drill sergeant screaming directly in your face with a megaphone. You’ll hear him but you probably won’t understand anything.
