How to set Proxy Settings when installing Oracle 11g on Windows 7 Ultimate Edition?
Your problem is almost certainly that you are entering an email address into the installer to receive information about updates. However this functionality will only work correctly if you also have a valid Oracle Support account.

Since you are in a home environment, I would leave the email address empty. The installer should then proceed without generating any HTTP requests to Oracle's servers.

You will however also have to download win32_11gR2_database_2of2.zip separately and unzip that into the same directory.
