We try to create a 52km link with NetMetal (RouterOS: 6.21.1)
Setting
channel width 20/40Ce
protocol: nv2 (with security)
Wireless Mode: onlyAC
We using a dual pol 34dB antennas
Signal is -51/-51
But link can't be established
Log says:
15:50:05 wireless,info 4C:5E:0C:7C:XX:XX@wlan1: failed to connect, on 5460000, medium-access timeout
15:50:21 wireless,info 4C:5E:0C:7C:XX:XX@wlan1: failed to connect, on 5460000, ranging timeout
Seems to be a distance problem, but also setting the NV2-distance to 80km nothing change

Hello,
Hard to comment without seeing configs, but 70% probability, that you did config mistake.

Re: 52km NetMetal-AC Link
Sure its config mistake, but your conf looks ok, i have a 60km link with the net metal 5 ac, and i love it, btw im using Jirous Antenna Ubiquiti antennas also work ok but no the same as Jirous

Re: 52km NetMetal-AC Link
Some details of your configuration?
You use NV2?
tdma period size
cell radius?
channel width?
Only AC?

Re: 52km NetMetal-AC Link
Lupin.
I am not sure if ac works with this set of wireless config:
if you will change it to
what happens?
Station connects to ap?
what records appears in logs when station connecting to ap?
And what reason is to use ???

Re: 52km NetMetal-AC Link
post the logs from the AP and the Station.
Make sure that you have specified the correct nv2-preshared-key on both ends.
Try setting the tdma-period size to a static one, for example 2.

Re: 52km NetMetal-AC Link
Setting tdma to 2ms as suggested, link go up
So, BWtest show me bad results.
Frequency 5460, 40Mhz, Ce

Re: 52km NetMetal-AC Link
Could you try attaching images now? I am curious to see your config as well.Sure its config mistake, but your conf looks ok, i have a 60km link with the net metal 5 ac, and i love it, btw im using Jirous Antenna Ubiquiti antennas also work ok but no the same as Jirous

Re: 52km NetMetal-AC Link
Found the best frequency
TDMA Period Size:2ms
Channel Width: 20/40Mhz Ce (with 80MHz is worse)
Wireless Protocol: NV2 (with security)
RouterOS: 6.21.1
Results UDP Ping

Re: 52km NetMetal-AC Link
150mbit/s over 52km is nice. Can you tell us more about your setup.
- How does the are look like?
- Meters over ground?
- Output power?
Re: 52km NetMetal-AC Link
Sorry, this is the main link 43 km on old software
another link to complete de full link
after upgrade main link but nv1 very stable 200 mbps 1- 2 ms
config nv1 ap
confi nv1 st
on nv2 de only diference is that i use tdma period size static on 3ms for more than 30km on less 2ms and at least 5 km more on cell radius.

Re: 52km NetMetal-AC Link
Great. Which antenna do you use - Mikrotik, Ubnt, Jirous?
