I recently purchased a replacement Vaio but seem to have a problem with the wifi on the machine. It rarely remembers the wifi networks that I connect to everyday and just won't connect or drops trhe connection frequently. I have to use the Windows Network Diagnostics to get it to reconnect now and it's really time consuming and annoying. The Vaio has Windows 8 PRO and an Intel Centrino Wireless N-2230 and is using the most up to date driver.
