Dead zones in the office, a guest network that keeps dropping, or an internet connection that slows to a crawl every afternoon, these are wireless and connectivity problems, not full network failures, and they need a different kind of fix than replacing your entire infrastructure.
At The Computer Guyz IT Services, LLC, serving Charleston businesses since 2010, we specialize in diagnosing and fixing the specific issues that make WiFi unreliable: overloaded access points, interference from nearby equipment, poor router placement, and ISP-side bottlenecks. We map your actual coverage using site surveys to find exactly where your signal drops, instead of guessing.
Whether it’s employees who can’t hold a video call in the conference room or customers complaining about slow guest WiFi, we fix the connectivity problem directly instead of selling you a bigger network overhaul than you need.
What does WiFi and internet support include?
It includes wireless site surveys to map dead zones and signal strength, access point placement and configuration, guest network setup separated from your business network, ISP troubleshooting, bandwidth and usage monitoring, and ongoing support when a dead zone reappears.
Why is my office WiFi slow or dropping?
Common causes are overloaded access points, interference from nearby equipment, poor router placement and ISP-side bottlenecks. We map your actual coverage with a site survey to find exactly where the signal drops, then fix that problem directly.
What is the difference between WiFi support and network support?
WiFi support is about the wireless experience your team and customers feel every day. If the issue runs deeper, like aging switches, server connectivity or your broader network architecture, that falls under our network support services.
How much does WiFi support cost?
We start with a free wireless assessment to show what is causing your dead zones and how to fix them. You can also request an instant quote on our pricing page.
