can't switch on the wireless adapter. diagnostics say its fine. network diagnostics tell me to switch it on. when I switch the manual sliders at the front the light goes green but only the bluetooth comes on. in the sony smart diagnostics it only list the bluetooth.
Knowing your model number would probably help someone to advise more accurately, but check that WLAN is enabled in Vaio Smart Network. You can access this via Vaio Control Center > Network Connections.
