I tested the household power yesterday and turned the Gateway off for 2 hours.
Resetting Factory Defaults
When it came up the wireless wouldn’t work. So I rang Linksys and they talked me through resetting factory defaults.
For those of you following me, you must document your encapsulation and consequent parameters, your wireless settings and encryption passwords and any firewall ports that are open.
It seems that the reliability of a system boot after a sustained power down is not 100%.
Powering Down
I was recommended to power down the gateway by removing the power lead from the appliance. I assume using the switch on the wall plug is equally effective. Don’t use the power switch on the front of the box. This is a deeply flawed piece of UI design 🙁
