It is the second time this happens: after I disassemble my HP dv9000 laptop to clean and vaccum some dust from the keyboard and fans the Clock and the Calendar reset (got back to the date of factory assemble), and I can't connect to the default Router - Wireless Connection on my house (which has the option to connect automatically to it) but the files stay the same and nothing happens in terms of files and data...
My brother fixed that last time by changing something on the Wireless setting, but I can't figure out what -.-
What have I done wrong and how do I fix it?
