First of all I'd like to say I've read topics but I have not been able to find an answer. I've had a power cut and when my PC with Windows 7 64-bit (12Gb RAM / Core i7) reboot, I've lost my perfectly working Internet connection. Now there's an "unknown network = Public network" instead. I've tried several things and this stuff really drives me nuts:
I've tried:
- to uncheck IPv6 because I've read somewhere that IPv6 may mess everything (sometimes). No success.
- to turn off network discovery. No success.
- to uninstall (not disable, uninstall) my network card so that it's re-detected. No success
- to remove the Admin password = no password for admin. No success
- try to set default gateway but no success
- the only solution that may work is by using
gpedit.msc
but, of course, it's not available for the Windows 7 home edition
I'm using my laptop with Ubuntu on it: absolutely no problem at all. This really drives me nuts. This is the first time in 15 years of computing that Ubuntu is better than Microsoft. Does this mean something? I've paid to upgrade from XP to Vista (because, as a Web developer I needed to test my websites with IE9). Vista was such a crap that I gave up and I paid once again $135 to upgrade to Seven home edition. And now I can't access Internet only because of a lack of intelligence of the team who created Seven (the network part to the least).
My network configuration is simple:
- My "big" PC which is connected to the "Internet Box" with Ethernet cable (I avoid Wi-Fi when I can)
- My laptop which is connected to the "Internet Box" with Ethernet cable too
- The Box with Internet access that acts like a switch too (=4 Ethernet plugs for local network)
So :
(Internet) <=> FreeBox (local IP 192.168.1.254)
^ ^

| +-- laptop Ubuntu (inet adr:192.168.1.25)

+----- big PC with Windows 7 (see further for IP config)
I've tried to config "by hand" the IP config ("192.168.1.51" with default gateway "192.168.1.254" and DNS "192.168.1.254". No success = "unknown network")
Any idea how to solve my problem?
Here's my ipconfig /ALL
