Hello Mike, Sorry. I should have mentioned that the voltage moves from 23.9V when quiescent to 23.4V when flat out. The run of CAT5 is about 18m.

Hi Steve, I suspect that it would be more likely to be related to voltage drop due to increase in power consumption as the radio activity ramps up. If the power circuit resistance is high (e.g. long PoE cable) then as the radio activity ramps up, the current drawn increases and thus voltage drops. Since radio systems are essentially a peripheral device to the routerBoard, if voltage drops too low then that peripheral will become unavailable and appear as if it has been virtually unplugged from the system. RBMetal has voltage monitor - check it and see if there is any change during radio operation. Cheers! Mike.

Can anyone tell me if there is a thermal shutdown arrangement within the wireless component of a RBMetal2SHPn?
I have a pair of RBMetal2SHPns on a 13km link and if I turn up the power to get good throughput, the RBMetal2SHPn sending the data shuts down its wireless after some minutes of maximum throughput.
The wlan interface still shows as up, but snooping from the shut down end reveals no stations where it normally shows many. It requires a reboot to get it going again.
It feels like a thermal issue, but the system temperature does not change, and its cold outside .
Any help appreciated.
Steve.
