152 If Something Goes Wrong DVD operating problems The Windows® operating system wireless management utility does not work. If you are using an external Wi-Fi® adapter (USB adapter or other variety), check if the adapter comes with its own management utility. If it does, the utility may be disabling the Windows® operating system wireless management utility, in which case you must use the adapter's management utility. If the documentation that accompanies the adapter does not provide enough information to determine if this is the case, contact that vendor's support group for further advice.
