Hi I have win7 (upgraded from Vista) on Acer T690 and have recently got a wireless Netgear router/modem. I have a notebook (XP) that I would like to connect to the net. I have had success FINALLY with that. Problem is when I select network discovery in homegroup it won't turn on. When I check again it is turned off. Same with media streaming. Is there a box I should check somewhere? When I try to get help I am told to select network discovery but it's useless as it won't change. VERY FRUSTRATING!
