Okay. I've been Ad-Hocing my Cable connection by wireless from my new computer to my old (Both Win 7). It was working absolutely fine, then I went to make dinner and when I came back, no internet(connection:yes, but no internet). There were absolutely NO active processes whatsoever except Process Explorer and a few svchosts that I know better than to suspend. What the heck happened in those 20 minutes? Now it won't even work if I directly plug the cable in. My new computer still connects fine. Also, now it's calling it an Unidentified Network and Public when it was set on Home. I can't change that either, for some unknown reason. Now I know this question has been asked many times before, but my case must be somehow different. I've lurked through about 20 threads on this subject, and I've tried ALL the "solutions" to no avail. In total I've: Disabled/Enabled my NIC (Realtek) and my Wireless (Netgear) 15 times Run the Trouble shooting Wizard ??? times (I lost count) Rolled back and Installed Drivers from Manufacturer's Website 2 times Slept/Woken My Computer 2 times Rebooted my computer 8 times Creating a new Ad-Hoc network 3 times Unbinding/Rebinding IPv4&v6 2 times (1 each separately, 1 both) ipconfig/release & /refresh 4 times Completely Shut Down, Unplug Both Computers & Modem, then restart 2 times Disabled Bonjour Service (##ID....etc) Disabled/Port Opened/IP Allowed through both firewalls 4 times and even done a System freakin' Restore twice!!! (3 days and 5 days) So, what do I do now? Also, safeboot is not an option, because internet would be pointless w/out my 3D graphics card running. However, if there is a way to use my GC in safe mode, by all means, please tell me how. That's fine too.

What wireless router? I'm just using an Ad-Hoc network from New comp w/ built-in wireless card to my old comp w/Netgear dongle(USB). Also note that direct connection to Cable Modem does not work anymore, as I said in my question. Again, also note that every thing was working fine for a few days, then it suddenly failed. That link explains what to do for XP and earlier. I need 7 instructions, please.

Hi, Please try to assign a static IP address for you wireless adapters to check what the result is. Hope it helps.
