I have used Ubiquiti for my home network for years, and it has always worked great at what it promised to do for me. People’s frustrations with it—in my experience—usually revolve around things they want it to do that it doesn’t, and the fact that it is very unfriendly to hacks or jury-rigging. So you have to be very sure going in that it matches your requirements. It’s like Apple gear.

Another option you could look at is TP-Link’s Omada system, which is basically their clone of Unifi but has a wider variety of hardware options.

I also often see people using Ubiquiti switches and APs in combination with a pfSense firewall if they want more sophistication and configurability. If you’re coming from Sophos and want to do sophisticated routing and filtering, you’ll probably find the Unifi firewall lacking in features (but it works great for people who don’t want to do that).

That is a connection to a roof-mounted TV aerial from back in the days when that was a thing. No, you can’t use it for internet.

Some scoping questions:

• What’s your comfort level with general system administration tasks?
• Do you have a day job in tech? Are you comfortable doing things like setting up Docker containers, working with a Unix command line, etc.?
• Do you have Ethernet runs in your walls?
• Where in your house do you intend to put the rack? How big is your house?

Don’t buy Cat8 cable, the router doesn’t have the hardware to benefit from it. Save a buck and get this Cat6 cable instead.

What router are you replacing?
