I've just joined NOW and got my router, and my srart date has passed so all good to go. Router working. My HP laptop "sees" the router but is asking for Network Security Code. The router has on the back a password and a PIN but neither of these works on my laptop so where do I find this Network Security Code?!
and many threads like it when you Google the issue.
But try the remedy shown in the quoted link, and see if this resolves it,
Failing that, I suggest a call to the Now Broadband helpline, using the number given in your welcome pack.
I received no Welcome Pack!!!
