M2000 MiFi vs ethernet router

Sorry it didn't work out as planned! Although an extra expense, I would recommend getting a more capable router. Personally, I'm a big fan of the Pepwave Surf Soho as a fairly low-cost (about $200) router for the functionality it provides as well as the extra security (many "consumer" routers - like the Actiontec - have gaping security flaws that are never fixed).

The Pepwave router supports up to 16 VLANs  - which can include Ethernet ports (so for example, you have a separate Home, Work, TV and Guest networks), which can route between them if you want. It also supports WAN over USB. I have a MiFi 8000 hooked to the USB (going to get the M2000 soon), and don't use the wireless on the MiFi at all (just use the wireless networks on the router). Here is the information that convinced me to purchase and no - have no affiliation with Pepwave or this person, but I am a big fan of the router: Pepwave Surf SOHO Router (routersecurity.org)

The rest of that site has also got some very good overall information on router security.

Cheers
