The network is one of those things nobody notices when it works well, but that brings the business to a halt when it fails. Most serious problems don’t appear overnight: they give warning signs weeks in advance. These are the five most common ones we see in companies in Costa Rica.

1. The Internet “gets slow” at certain times

If speed always drops mid-morning or after lunch, it is rarely the Internet provider’s fault. Most often it’s an internal bottleneck: an overloaded switch, outdated equipment or too many devices hanging off the same access point.

An audit measures real traffic per segment and finds exactly where the network is choking.

2. WiFi drops or has dead zones

Home WiFi can handle a handful of devices. An office with 20, 40 or 100 devices needs a different class of equipment: business-grade access points, well placed and with roaming between them. If your staff lose their connection when walking from one office to another, the solution isn’t “restarting the router”: it’s redesigning the coverage.

3. Everything shares the same network

When employee computers, security cameras, IP phones, the point of sale and guest WiFi all share a single flat network, there are two problems: security (any compromised device can see everything else) and performance (some devices’ traffic chokes the others).

VLAN segmentation separates those worlds, in most cases without buying new equipment.

4. Nobody knows what’s on the network

If there’s no up-to-date inventory of switches, access points, cameras and connected devices, the network grew on its own. That means open ports nobody manages, default passwords and years-old firmware. An audit always starts by documenting what’s there.

5. When something fails, nobody knows where to start

Is it the provider? The router? A cable? If every incident turns into hours of trial and error, monitoring and centralized management are missing. With a well-configured platform such as UniFi or MikroTik, you can see the status of the entire network on a single screen.

What a network audit includes

  • Inventory and mapping of active devices
  • Measurement of WiFi coverage and congestion points
  • Review of segmentation, passwords and firmware
  • Report with findings ordered by priority and an improvement budget

At SYSCOM we carry out network audits for companies of all sizes. If you recognized two or more of these signs, it’s worth having a conversation.
