Questions about this item

How do I install the Dell Wireless 5600 WWAN card into the Mini-PCI Express slot and which step is often missed?

Insert the card at an angle into the Mini-PCI Express slot, secure it with the retaining screw, then connect both antenna cables to the numbered connectors on the card; the step most often missed is attaching both antenna leads.

What maintenance or replacement will the Dell Wireless 5600 card need over time?

The card itself has no user-serviceable parts; replacement is only needed if the card fails or if you upgrade to a newer mobile broadband module compatible with the same slot.

What is the first limitation you hit when using the Dell Wireless 5600 continuously for long periods?

Sustained data sessions are limited by the HSPA/EVDO network speeds available in your area and by the thermal envelope of the laptop chassis housing the card.
