Base Station not working

Hi,

I have an older version of simplisafe. My base station is not connecting to the dispatch service. I tried ooptions mentioned in the forum such as taking out the batteries etc., but didn't help. On my online account, it asks me to enter master pin. I did that,  but then it ssays "wifi not connected". My base station doesn't connect to wifi. Does someone need to activate it?  Please advise.

Regards,
Aseem
