Right now we are still tossing around getting the router for the Wineguard in our 310RL the going with a sim card or two to keep connectivity . Went out camping last weekend and I have found I cannot get the TV in the rig to attach to my iPhone 12Pro for internet access. Spent a few hours then finally gave up trying to figure it out. I've also looked at the TechnoRV Pepwave system as well. Too many options to try and figure out. Just want to be able to access internet, watch TV, and work if necessary in a part-time RV living environment. Frustrated at best at the moment. Thanks
@bhidalgo - Getting decent cellular-based Internet in an RV starts with obtaining a viable cellular signal from a cell site with enough bandwidth provision to it. For most consumers, knowing what tower to choose or even having more than one to choose from, isn't easy to find out or do. But there is something we can do.
I was in the RF field for 30 years prior to my current stint in the RV field since 2008, My past experience lends itself useful in RVing at times. That said, I start with receiving the signal. This usually involves installing an external cellular antenna. There are many options out there and they break down into two main categories: Direction and Omni-Directional. Then within those antenna types, you're looking for Gain across the frequency band you need (depending on your cellular carrier and their offerings).
I will usually go with a higher-gain omni-directional antenna due to it's versatility and zero need for operator adjustment. I also try to elevate any antenna above the roofline rather than mounting it at roof level. In my current Paradigm 340RL, I will be installing a Poynting 7-in-1 omni-directional antenna on a bracket that I will make from 1" wide flat steel stock. I'll bend the steel in a vise using my hands and a hammer. Once formed into 2 matching brackets, I'll drill mounting holes and paint the brackets white, mount them to the antenna and mount it to the roof. The design goal for the brackets are to have the top of the antenna even with the height of the nearest rooftop air conditioner case. I also want to mount it no closer than a couple of feet from the air conditioner or a roof-top satellite dish. This gives me a fighting chance to receive a decent signal if one is available.
Indoors, I use a router that has external antenna ports that I can use for my rooftop antenna. In my case, over the past 6 years or more, I've used Pepwave cellular routers and have been very pleased with them.
At this time, I'm using a single SIM (Verizon). Most Pepwave routers can accommodate 2 or more SIMs. Mine has 2 full modem channels in it and each channel can have 2 SIMs - so lots of flexibility if I was willing to shell out for simultaneous data plans.
This is getting long so I will close. Above is my 2 cents on Antennas and Routers. Don't skimp on either. And with all that said, there's nothing wrong with trying to leverage the antenna array inside the dome of your Wingard product and trying their router. I tried it early on and wasn't a fan of the UI (user interface). I'm sure it's improved since the early days.
