If your Wi-Fi drops in certain rooms, slows down at night or forces you to reconnect on the patio, the network was probably never designed for the size of the house. In properties over 4,000 square feet - and almost every hillside or multi-wing estate we service in Los Angeles - one router simply cannot cover the floor plan, no matter how expensive it is.

Why it happens

Three causes come up in nearly every site survey we run. First, distance and construction: plaster, stone, steel framing and low-E glass absorb 5 GHz signal aggressively. Second, wireless mesh systems that repeat signal over the air lose roughly half their throughput at every hop, so the far end of the house gets a fraction of the bandwidth. Third, interference: in dense neighborhoods dozens of networks compete for the same channels, and smart home devices add constant background chatter.

What actually fixes it

The durable solution is a wired backbone: enterprise-grade access points in the ceiling, each connected back to a central switch with its own cable, all managed as one network with a single name. Your phone hands off seamlessly as you walk from the theater to the pool. This is how offices and hotels are built, and it is how we build homes. Where cabling is impossible, a point-to-point wireless bridge or fiber run between buildings covers guest houses and ADUs.

What about mesh kits

Retail mesh is fine for apartments and smaller homes. But when a household runs 4K streaming, video calls, cameras and a hundred smart devices at once, contention and airtime become the bottleneck - and only wired access points solve that.

Ermine designs and installs enterprise-grade home networks across the LA Westside using Ubiquiti and Araknis hardware, with monitoring that lets us fix most issues before you notice them. See erminehub.com/services/infrastructure or book a consultation at erminehub.com/contact.
