rcwaz - There are so many experts writing articles that I hesitate agreeing or disagreeing with them. As I understand the Verizon Wi-Max card it will greatly exceed the speed of a modem when in the range of a special EV-DO (evolution-data only) Verizon tower. Transmission speeds are expected to be in the 1.5 mbps (1-1/2 million bytes per second). A common modem typically will have speeds in the 45-56 kbps (45 to 56 thousand bytes per second). When the Wi-Max card is in the range of a Verizon CDMA tower, the speed drops to a speed of 60 to 80 kbps. Either way, it should beat the modem. But....(a big but) is that this is theory and not always reality.
Not sure what Camping World is selling for $1,900, but a typical wireless/WiFi router costs around $60 to $80 at Best Buy. This router, or access point, will usually have 5 ethernet hardwire connections plus the antennae to broadcast the WiFi signal.
