Networks rarely fail dramatically. They degrade. A switch that reboots once a month, a wireless access point serving forty devices, a firewall rule added in 2019 that nobody dares remove. By the time the outage happens, the warning signs have been there for a year.
1. Your Wi-Fi has "the good spot"
If staff know which corner of the office has usable signal, you do not have Wi-Fi — you have a hotspot with extra steps. Coverage should be designed against the building, not inherited from wherever the previous tenant left a ceiling box.
2. Video calls stutter at the same time every day
Predictable congestion is a capacity or QoS problem. Either the uplink is saturated, or business traffic is competing with guest devices and cloud backups. Both are fixable, and neither requires a faster internet line by default.
3. Nobody can name the last person to change the firewall
Undocumented changes are the most common root cause we find during audits. If there is no change log, there is no way to roll back — only to guess.
4. Guest devices share your corporate network
A visitor laptop should never be one ARP spoof away from your accounting server. Segmentation is not exotic; it is baseline hygiene.
5. Your switches are past end-of-support
Unpatched firmware is a liability, and replacement parts become impossible to source. A lifecycle plan costs far less than an emergency refresh.
6. Backups have never been restored
A backup is a hypothesis until you restore it. Test quarterly, document the time it takes, and make sure the person who runs the restore is not on holiday when you need them.
7. IT hears about problems from staff, not monitoring
If your first alert is a person saying "the internet is down", you are monitoring nothing. Even a basic uptime and device-health dashboard changes the conversation from firefighting to maintenance.
Where to start
Pick the two symptoms costing you the most time and measure them for a week. That baseline is what any credible supplier should ask for before quoting a fix — and it is what will prove the fix worked.
