Believe problem software on computer as no problems through lap top. In services DCHP won't start as it says one of the dependant services isn't running, look in device manager for same services and all seems fine. Windows XP.
Have configured IP address's manually, now it connects but once every 30 seconds to a minute comes up network cable unplugged. Internet though running at 14M bits download nationally where on old USB one only got 3 M bits.
If try repair connection it comes up can't clear netBT.
Also if disable connection, then re-enable can't access internet/router even when says connected. A reboot puts computer back in business.
Seems like twilight zone to me, but if anyone can help much appreciated. The internet is racing with it, it's just it keeps coming up with that network cable unplugged message.
