Greetings; Re: Windows 7 and Vista. We have 2 computers which are hard wired to Cox. One has windows 7 and the other has Vista. We installed a wireless modem (Belk Surf N300) to accommodate a requirement to access books for a Kindle from Amazon. Besides that, it accommodates 3 laptops. Today, (Nov 8) I am using the computer with 7 and my wife is using the one with Vista. I was just reading e-mail and she was playing a game on Gamesville. While she was playing, the screen went white and a note came up saying she lost the connection to the server my unit did not change or lose anything. If we are on the same modem from the carrier (cox) why would she get that message while I got nothing. Anybody? Thanks.
