my AirPort Extreme base Station (Model 1084) needs to be updated from 32 bit to 64 bit
Model 1084 is not an AirPort Extreme......it is an AirPort Express model which was discontinued by Apple over 11 years ago. Apple has classified the 1084 model as Obsolete for over 7 years, so no support has been offered for this product in a long time.
If you have a PC, or a friend with a PC, you might be able to access the settings on the AirPort Express, but the PC software was designed to work on Windows 7.

Frankly, it is nothing short of a miracle that a 1084 model will even power up at all. Most of these devices died after 4-5 years of use.
