Sky booster middle light not on despite numerous times using wps

[Jackykats]

We had a power shortage and the electricity all turned off. Once back on the sky booster box wasn't connected so we used Wps button and nothing. Tried resetting, turning on and off, unplugging and several more times trying to reconnect with wps button. I'm close to just calling up sky and cancelling broadband it's been nothing but trouble.

After a power outage its usually that the booster is faulty either hardware wise or firmware wise.
