|Mmm... very long shots.|
Remove all power - battery inlcuded. Locate end remove the wifi module (carefully) if possible. Clean its contacts with something like a soft pencil eraser. Re-insert module securely, then remove and re-insert again. Then power up and see it helps.
Another - even longer shot... Remove all power (battery too). Press and hold the on/off button/switch on the laptop for about seconds. Release button, restore battery etc., power up and see if that helps.
Also is this laptop on battery or mains power whenit lose connection?
