Scotty,
hi.   You helped me with my wireless network last month.  I've been having trouble with the signal reaching the upstairs office, so I finally bit the bullet and purchased a new Airport Extreme.  (I have not gotten 2 new Expresses yet - just wanted to wait to see if the new Express would work.)  I am having trouble with getting the new one started.  In Airport Utility, it does not seem to be finding the new Extreme.  Is this something you can help me with over the phone?  Or should I schedule you to come out again?  Thanks so much.  Hope you are doing well.  I know you must be glad that school is winding down.:)

There’s a small chance there could be interference from other devices in the home but I would first start with resetting the extreme. Hold down the pin hole button on the back with a pen or paper clip until the light flashes a rapid orange. Then try to find the device again. However, due to the way wireless networks can be effected by house structure, it may be best to have me out to set the network up.
