in chrome, I Go to Settings/advanced/Network/Change Proxy Settings/LAN Settings and I uncheck the "Use a proxy server" then OK

"Unable to connect to the proxy server" even tho home network & data are fine

either you don't have a proxy server/or it is down that's why your getting " unable to connect to proxy server".. you can change it in control panel ...try search there it will give you the "internet option"

On Windows XP, click Start, or on Windows Vista or Windows 7, click start, and then click Run.
In the Run text box, copy (CTRL+C) and paste (CTRL+V) or type the following:

reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 0 /f

Click OK.

On Windows XP, click Start , or on Windows Vista or Windows 7, click start, and then click Run.
In the Run text box, copy (CTRL+C) and paste (CTRL+V) or type the following:

reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /f

Click OK.

If you don't have the run command in your start menu then press the "windowkey+R" then it should come out

If this does not fix the problem then you might have malware thats causing the problem. Download SpywareBlaster and ComboFix. That helped me get rid of all those malware.
