If all of this will be at your seasonal site and not expected to work anywhere on the road they you should go with whatever will support what you want to do there.
I use the ASUS RT-AC68U Wireless - AC1900 Dual Band Router using a ARRIS CM820A Modem through a METROCAST CABLE PROVIDER which is roughly a 20MB cable feed setup... About the only downstreaming over the internet we do here at the house is downstream missed TV SHOWS the following day or two after they are aired.
Everything else HDTV wise is sent to us over the cable HDTV connection which is separate from the Internet account...
Our METROCAST Modem/router high speed Internet Works great for what use our home internet for... METROCAST CABLE here fastest Internet plan for residential use is around 90MB I think it is...
This have nothing what-so-ever to do with I use when we are RV CAMPING... For us the VERIZON NETWORK seems to be the one that works the best when we are off-road camping... I use the VERIZON MIFI 3GB hotspot plan for use in my RV Camper when on-the-road...
