There was a lot of discussion a while back about routers. My experience was pretty much plug-and-play but others weren't so lucky. One thing most agreed on was to get a router with traffic monitoring capability built in, in case there were any questions about "disappearing" data. The higher end Asus routers have this capability built in. One problem is that the DHCP in the router sometimes wants to use the same IP range as the Viasat modem, causing IP conflicts.
