Mac Filter; Finding The Mac Address - Comcast High-Speed 2Go User Manual

MAC Filter

MAC filtering allows you to limit access to your 3G Mobile Hotspot to only those devices with a
specified MAC address (a unique code assigned to hardware such as network adapters).
The MAC Filter page allows you to enable or disable MAC filtering and to add or delete MAC
addresses from the trusted client list.
IMPORTANT
Do not enable MAC filtering unless you have added your own MAC address to
the trusted client list. Otherwise you will be unable to access your 3G Mobile Hotspot.
