I used to connect the internet wirelessly via my network, for some reason I cannot now, I've tried everything, I can only connect with the ethernet cable. What can I do?
What model Vaio do you have?
Have you installed the latest wireless drivers?
Does the wireless card show as working correctly in Device Manager -> Network Adapters?
If all else fails, the cheapest way to get it working wirelessly is to buy a PC Card wireless adapter or a wireless dongle for a few pounds.
