Preparing to sell my laptop but I'm having troubles connecting it to the internet. It's a Samsung 700z laptop. In the device manager there is the error sign for six of the network adapters: Intel(R) Centrino(R) Advanced-N 6235, Microsoft ISATAP Adapter, Micsosoft ISATAP Adapter #4 and #6, Realtek PCIe GBE Family Controller and Teredo Tunneling Pseudo-Interface. Not really sure what to do at this point, any help is greatly appreciated
