People ask us all the time what we use for internet access on the boat. It’s a vaguely complicated setup, so I figured I’d write it up in case others want to follow in our footsteps (or even better, have suggestions!)
The central router on the boat is a Cradlepoint COR IBR1700. It serves the wifi network on the boat that everything, including our cell phones, connect to. I’ve set it up to run off the 12V on the boat through a dedicated breaker switch that we leave on 24/7. The unit comes with an integrated dual-antenna (2×2 MIMO) cellular modem with two SIM card slots. You can add a second modem to it with an additional two SIM card slots, and if you have the antennae for it, you can split your bandwidth between the two modems. In all honesty, we’ve been struggling with this unit since we got it, and have had the whole unit RMA’d twice, and the second add-in modem RMA’d twice as well. The problems they’re trying to address are still unsolved, and our internet blinks out once or twice a day for several minutes while the modem spontaneously reboots. I’m probably going to call this wasted money and switch to another unit in the near future and sell this one off. For paying nearly 2000$ between the unit and the add-in modem, I’m not thrilled. But when it’s not spontaneously rebooting on us, it does work nicely.
Our backup router is a MOFI4500. It only has one SIM slot, so you’re manually swapping SIM cards to change networks. It only has a single cell modem, which is slower than the Cradlepoint’s cell modem, and the Wifi is slower as well. But not by much. It’s also cheap and just works. For most boaters looking to get a reliable cell internet connection on their boat, this is what I tell them to get.
The biggest piece of our connectivity puzzle is the antenna. We started with a WirEng GigaMIMO Lite, and while it was an improvement over just tethering, we wanted more, so we upgraded to the full GigaMIMO recently, and it was a pretty big boost. Both GigaMIMO units are 2×2 MIMO antennae, which means it’s basically two antennae in one, with orthogonal polarization, so they send non-intersecting wavelengths, for double the bandwidth (if you have a router that supports plugging in two antennae.) After upgrading, we now regularly get several megabits of internet when our cell phones show zero coverage or are just squeaking by on 1x. We have only lost connectivity in the absolute boonies for a few minutes on one day of the trip so far. The full unit is nearly 3000$, though, so you have to really want that internet to justify it, as well have somewhere to put what’s basically a 3 foot cube of antenna with an unobstructed-by-metal view of the horizon. But in even moderate connectivity, we usually have 20-30 megabits of download, and in good areas, we’ve cracked 90 before.
For actual data plans, we burn through huge amounts of data between work, gaming, streaming, and general browsing. We regularly use hundreds of gigabytes a month, which is far more than the standard plans will give you, so I had to get creative. We have three SIM cards on the boat: AT&T, Verizon, and Google Fi. The AT&T plan is through NoLimitData, and is a nearly unlimited plan (no throttling, 500GB a month warning line). The Verizon SIM is a no-longer-available prepaid truly unlimited plan (no throttling, no limits), though you can get something similar through UnlimitedVille. The Google Fi SIM is our backup plan and lightweight international roaming solution. On our great loop trip so far, AT&T has often had better bandwidth than Verizon, so it tends to be our default active SIM. I don’t yet have a solution for when we get to Canada. There don’t seem to be any actual unlimited plans there, no matter how much money you’re willing to pay, so we’ll cross that bridge in a few months as it gets closer.
Lastly, if wifi is available anywhere remotely nearby, we have a Wave Wifi Rogue Pro wifi booster on top of the boat, across from the LTE antenna. This works fairly well if there’s wifi within a mile or so, though we’ve gotten signals several miles away before under perfect conditions. Under almost all conditions on the loop, though, our cellular setup works so much better than even good marina wifi that we don’t even bother using this. We’ve only bothered I think once on the trip so far, and it was merely academic, while I was debugging some issues with the Cradlepoint’s cell modems. I expect we’ll be relying on this a lot more in Canada, given the likely no-unlimited-data solution we’ll run into there.
