Currently have DSL and wanted to get more speed, reliability and portability. Looking at the Verizon Jetpack and it only seems to be a wifi type router. Home is wired for Ethernet and was wondering if there is a way to get the jetpack signal into the ethernet system. Some of my devices are in far flung areas and so wifi would be sketchy. Seems like at one time I saw a USB/ethernet adapter. Next question will be; just how many gig's can I afford and what will be sufficient. The portability angle is that I would like to take it with me in my RV, need this for security and camground unreliable wifi.
