My product number is: B7R54EA#ACQ. it is a Pavilion dv7-7120ei. Wireless is Inten Centrin N2230.
The machine came with Windows 7 Home Premium installed. There were flyers and stuff in the store and with the machine encouraging buyers to upgrade to Windows 8 as soon as it became available. This was last year in October.
I upgraded to Windows 8 Pro 64-bit three weeks ago and it has been nothing but trouble since then.
In addition to the wireless issue, the printer drivers (Office jet 4500) will make the printer put paper through, but it always comes out blank.
