One network, not several

Many homes end up with overlapping WiFi networks from old routers and extenders that were never removed. Simplifying to one well-placed network is often the biggest single improvement.

Wired where it counts

Smart TVs, game consoles and desktop PCs run noticeably better on a cable than WiFi when one is available. A short cable run can solve a problem no amount of WiFi tuning will.

Set it up once, properly

A network set up correctly the first time, named clearly, secured, and positioned well, needs far less fiddling later than one patched together over the years.
