Slow Wi-Fi Fix in Charlotte, NC

Slow Wi-Fi in your house is one of the most common calls we get in Charlotte. Videos buffer upstairs, work calls freeze in the home office, and the back patio has no signal at all. Sound Advice finds out why your Wi-Fi is slow and fixes it for good with properly designed whole-home Wi-Fi, so every room gets the speed you already pay for. Because low-voltage systems are our focus, we can wire the network the right way instead of adding another plug-in extender.

Why Is the Wi-Fi Slow in My House?

Most slow Wi-Fi problems are not the internet provider. They come from how the Wi-Fi is set up inside the home.

One router for a large home: a single router in a closet or basement cannot cover two or three floors, a bonus room and the yard.
Building materials: brick, stone, plaster, tile, mirrors and HVAC ducts block or weaken Wi-Fi signals.
Wireless mesh with no wiring: mesh units that talk to each other over Wi-Fi lose speed with every hop.
Old or overloaded equipment: a router from years ago may not handle 40 to 80 connected phones, TVs, cameras and smart devices.
Interference and bad settings: crowded channels, mixed old devices and default settings drag everyone down.

How We Fix Slow Wi-Fi and Dead Zones

Wi-Fi Assessment

We test speed at the modem and in each room, map dead zones, check your equipment and count the devices on the network. You get a clear answer on what is wrong and what it takes to fix it.

Wired Access Points

The biggest upgrade for slow Wi-Fi is running Cat6 cable to ceiling or wall access points. Each access point gets a full-speed wired connection, so the signal is strong in every room, not just near the router.

UniFi Whole-Home Wi-Fi

We have been installing Ubiquiti UniFi since 2014. A UniFi gateway, managed switch and access points give you fast roaming from room to room, a separate guest network and a network for smart devices.

Outdoor and Outbuilding Wi-Fi

Outdoor access points and point-to-point links bring coverage to the pool, patio, dock and detached garage.

Backup Internet

If the internet itself drops, a gateway with dual-WAN failover can switch to a second connection such as Starlink automatically. See Starlink internet in Charlotte.

Whole-Home Wi-Fi for Charlotte Homes

Older homes in Myers Park, Eastover and Dilworth often have plaster walls and brick that block Wi-Fi, so wired access points make the biggest difference. Larger newer homes in Ballantyne and around Lake Norman need several access points to cover three floors and the yard. If you bought a home with an existing Araknis network, see our Araknis network installation and replacement page.

Slow Wi-Fi Can Also Mean No Cell Signal

The same walls that block Wi-Fi also block cell signal. If calls drop inside your house, strong Wi-Fi makes Wi-Fi calling work reliably. Learn more about fixing poor cell signal at home.
