Hey guys,
Yea, there is something definitely very wrong with these 2G Metal Grooves. I have this same problem. As usual Mikrotik will first assume we have no idea what we are doing and suggest normal troubleshooting steps first and waste a good couple of days ignoring the problem.

On the other hand, I’m quite happy with them 
It’s just a matter of spending some time to configure and fine tune the radios for best production performances.
If you want to use a 1600mW capable radio on 2,4GHz, use it on a PtP 50Km link and I can assure you it works if you pick the right antennas
Cheers

Thanks Steven for help us but i didn’t think the problem from antenna coz some peoples try another types from antenna and the same problem . if u have time come and see with team viewer what’s the problems

I can see where in a PtP setup it would work well. With just one client, setting the ack/distance manually or enabling nv2 would resolve the problem. I believe the problem lies with how the device is calculating the ack setting dynamically.
Is this a PtP or a PtMP.
What equipment do you use as station?
if u mean in Advanced option >> Distance , i change it from dynamic to indoors and the same problem
i make it Ap bridge not station (( mode=ap-bridge ))
Yes but what type of equipment do you use as stations?
Is it Mikrotik, is it Ubiquity, is it Android, IOS or Windows?
LOL
Steven
sorry understand you wrong
stations by tp-link access in normal pc ( windows ) 
give this a go, see if it works.
you shouldn’t have a problem unless you have a NLOS issue there…

thanks Steven i try it and the same problem access client connect and disconnect again
i need to ask about the Power in System >> Health >> ( Voltage = 23.6 V Temperature = 39 C )
this good or have problem
Picture from Metal
I would say this is normal on your setup… as far as I understood you have a AP ( RB Metal2) providing connectivity to PCs, laptops and all sort of other hand held devices…
is this the case?
Steven
after 47 min some client access disconnected and others still connected
you didn’t answer my question!
