Key points about 4G routers:
- Understand how they connect to your network and what they do.
- Do not assume automatic switching without confirmation.
- Check if your ISP supports 4G and what the setup involves.
- Avoid using a single router for all connections unless you’re sure.
Dos and don'ts:
- Always verify compatibility before purchasing.
- Test connection stability after installation.
- Do not ignore warning signs of poor performance.
- Keep backup options ready while testing.
Don't buy the cheapest thing you can find. Get one with two external antennas and which isn't powered off your USB-port. You can't connect them to the same network anyways, unless your current router has dual-WAN functionality. Depends entirely on the 4G-router. Many of them only use 4G for the Internet-connection and have no WAN-port at all. Also, even the ones that do also have a WAN-port are typically configurable in the settings as to which connection it should primarily use and which one should be the backup-connection. As for a drop of connection: yes, if the router has to switch between the two, you'll see a temporary drop of connections.
It seems like you meant to clarify that. I didn't catch the reference to a plan from the telecom company.
I noticed this was my initial check. Unfortunately, no nearby networks offer strong signals in this location, which is why I’m opting for a router instead of just a USB dongle. I’m hoping to find something with a weather-resistant antenna or at least one that fits in my attic/loft for optimal performance.
