The Top 5 Network Misconfigurations We See (and Fix)

We support installers, property managers, and small businesses every day — and we’ve seen just about every type of network headache out there.

Here are the top 5 issues we fix most often:

  1. Improper VLAN Segmentation
    Devices that should be isolated (like cameras or guest Wi-Fi) are all on the same network, causing slowdowns or security risks.

  2. Incorrect Port Forwarding
    Remote access doesn’t work because the right ports aren’t open or mapped to the wrong internal IP.

  3. DDNS Not Set Up (or Set Up Wrong)
    Without Dynamic DNS, clients lose access every time the IP changes — especially with residential-grade internet.

  4. Double NAT or ISP Conflict
    We often find modems in router mode stacked on routers — which kills remote access and causes unstable performance.

  5. No Documentation
    We get called in and no one knows what IPs were used, what firmware is installed, or how anything was configured.

We don’t just fix these — we prevent them by setting things up right the first time, and we include clear documentation so your clients (and your future self) know what’s what.
