Start with the scope
Find out whether slow internet affects one user, one device, one website, one Wi-Fi area, or everyone in the office.
Check wired vs Wi-Fi
If wired devices are fast but Wi-Fi is slow, focus on signal, interference, channel congestion, access points, or device Wi-Fi settings.
Check latency and packet loss
A speed test is useful, but ping and packet loss tests can reveal problems that speed numbers do not show.
Look for background usage
Cloud backups, updates, streaming, downloads, malware, or large file transfers can consume bandwidth and make the network feel slow.
Document before escalating
Record speed test results, ping times, affected devices, times of day, and whether the issue happens on wired, Wi-Fi, or VPN.
