If Something Goes Wrong DVD operating problems 151 The Windows® operating system wireless management utility does not work. If you are using an external Wi-Fi® adapter (a 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. DVD operating problems If you experience a problem playing DVDs, you may be able to fix the problem yourself.
