My home router is on its last legs so I need a replacement. I'm not sure I'll go with an all-in-one modem/router again since there seems to be less support out there for them, plus any new technologies would require a separate modem anyway (e.g. my current router doesn't support G-Fast). I've heard good things about Ubiquiti but I just went to their website's "products" section and it just lists like 100 products. How am I supposed to know what I want? Do they not have a product chooser page?
No, they’re generally not retail products. Most of them are targeted at Small and Medium businesses where they have an IT person or an IT consultant. They do have a consumer product range - Amplifi but I wouldn’t go down that route.
If you have G.fast then you’ll still need a G.fast modem to use any ‘cable’ router which is what the Ubiquiti products are targeted at.
It’s also important (and I think you’ve done this) is to get yourself educated about what’s in that ‘router’. So it’s the modem, the router, the switch and the access point. Do you want these all separate or do you want an all-in-one unit?
So for a complete UniFi separates system you’d want a G.fast modem from Openreach, a router (UniFi Security Gateway or USG), a switch (they make a wide range) and an appropriate access point. Or the all-in-one solution is the UniFi Dream Machine which is a router, switch and access point all in one. You will still need a G.fast modem though.
And it’s REALLY important to be realistic about what the UniFi access points can do. There are legal requirements for the radio in them and they can’t defeat the laws of physics. What they do allow is to add more access points easily so you can get the WiFi to more areas really, really, easily.
You’re doing the right things. Doing your homework, asking questions. But no, they don’t make it easy for you.
