i restarted my computer today after installing updates and when i logged in it says i dont have a internet connection. in metwork connections all are enabled and are connected but there is no information going in or out. i try the repair function but it says failed to renew ip address. the other computer on my network is on the internet fine but mine is not. i tryed uninstalling the NIC and restoring the computer back to when it did work but with no luck. many thanks in advance.
