Within the last 2 months, my win 7 computer takes between 10 and 20 minutes to connect to my router. Once it is connected I have no problems. I dual boot Win 8 and that has no problems connection immediately. Prior to 2 months ago, I would connect up right away.
What happens is that I see the icon in the lower right of the task bar and it will have a blue circle going around (the usual waiting thing). sometimes I get the square box with the yellow flag but not always.
I have search all over the net and cannot find anything that works.
