The install math for a Wisconsin household
Median Wisconsin household income: $75,670. Typical internet stack runs about $75/mo, or $900/year — about 1.2% of pre-tax income. If you want a pro install (mount + cable management + Cat6 to the router from the network closet), Wisconsin-area rates run about $135/hr; typical job is 4 hours = roughly $540.
What Rick recommends in Wisconsin
If you can get fiber here, take it. Fiber-to-the-home means symmetric upload — which matters more in 2026 than it did even 5 years ago, because every household now has at least one work-from-home video call per day. For Wi-Fi: skip the carrier rental gateway, buy your own Eero or Orbi mesh, save $10-15/month on rental, and you keep the gear when you switch ISPs.
