Hmmmmmm. Risking sounding like a fool, I will take a stab at a guess: solar activity?! I know the northern lights have been quite active and enjoyable this past week after not seeing them for quite some time. I do have wireless at home, so I'm not hard wired in, and my phone out in the bush each day runs cell 3G only........I know so little about what I'm talking about other than some warnings we hear when solar activity is up
