Coverage on how to determine if your extender is cool with your router is in the following troubleshooting section...MAKING THE LIGHTS TURN BLUEa

Since Verizon is the only supplier of compatible extenders for their network they pretty much own the market for these devices and thus there is no pressure to lower pricing or improve the extender

The main difference I am aware of is that this older extender only can only download data at "1x" speeds (much slower than 3G)

The extender runs pretty warm to begin with

Just remember in all these examples that unlike WiFi, you can't password protect your extender

Verizon's Tech Support recommended the Samsung Network Extender as I live in an area that currently has very poor reception

It might be a bad extender, or perhaps you live outside Verizon's "licensed spectrum"

Second -and this addresses the router incompatibility issue- temporarily plug your extender directly into your broadband connection
