-- Posted by Mentally Disturbed at 5:59 am on June 21, 2009 I have quite a strange internet problem going on with my computer. Currently I have the machine dual booted with Windows 7 RC and Windows Vista Ultimate. I use the Win 7  and my mom and brother use Vista. My mom called me at work yesterday and told me she could not get on to the internet so I came home and tried renewing the IP address and everything. But for some reason when i try pinging the router it is unreachable and when I try ipcofig /renew it gives me an error. However I am able to get on the net using the Win 7 boot. So could someone explain to me what is happening here and how I should proceed in trying to fix this?? -- Posted by Light Assassin at 6:10 am on June 21, 2009 use a wired internet connection? restart the router? -- Posted by Mentally Disturbed at 9:37 am on June 21, 2009 I have restarted the router many times and even the computer.
