They added the ability to turn it off. Many of the new PTMP radios on all manufactures reset with a similar pattern. Otherwise use a UPS.
the sequence is pretty hard to randomly get, the radio has to be power cycled. then on for at least 10 seconds, but not fully booted. then off for 3 to 5 seconds, back on for 3 seconds, back off for 3 to 5 seconds then back off for 3 to 5 more seconds for the reset to happen.
unfortunate, you were extremely unlucky as a normal power outage or even a few surges don't happen in that specific of a pattern often
the pattern is specified on page 263 in the usermanual for release 2.5.1
How did I miss this ! ! I know what I'll be doing to all our radios tonight.
We had all six APs on one site default during a storm. Also defaulted 7 customer radios all within a couple of blocks of the tower. Have serveral customers with remote solar set ups and recently has several of them running a single 12v cheap battery setup default after about 5 days of very overcast, rainy, drizzly weather. We have one customer that is running his off some rinky dink black&decker solar / battery thing and his radio has defaulted 3 times in the two months he has been a customer. We finally told him this last time (yesterday actually) that he needed a better power setup and that we would start charging him a service call for coming out and reprogramming his radio.
Hopefully it was the power off/on in the correct pattern resetting them and turning it off will remedy the problem. If it was a low voltage issue, especially on the solar customers, the I wonder if turning that off will actually help.
