Hello, came down this morning to find that I had no connection to the router at all.

Yesterday it was powered down while the phone line was repaired.
It has needed resetting often recently while sky has gone down.

Anyway, I could not find our network in the listings, but I could find the default one from on the bottom of the router.
I have asked the rest of the family & no one admits to resetting it.
Firmware is set at V1.03.87

Is this just a "something" that may have happened?
