I've had this 13.7 mile link running v2.5, 5.1 band, 20MHz, non-GPS
radios for 110 days without any issues. I switched the slave scan to
include 40MHz and then moved the master to 40MHz width the other day.
Since then it appears the slave has been rebooting. However this
morning, the link wasn't passing traffic for over two hours, then it
magically fixed itself. An hour later and it rebooted. I remember
reading some stuff, possibly release notes, that the ePTP slave could
reboot under heavy interference. This link is on a very clean channel
though. About -58 RSSI and it maintains MCS 15 both directions nearly
all the time.
So I don't have a clue. Ran perfect on 20MHz channel bandwidth. Just
needed a little more throughput out of it, thus 40MHz. I just upgraded
both ends to v2.6, so I hope that fixes it.
And no, these radios are not CE+ MACs.
