Internet Health Check guide
How to prove your internet is slow to your ISP
ISPs act on dated evidence, not feelings. Collect three things for one week: when each slowdown happened (timestamp), how long it lasted (duration), and measured speed versus the plan you pay for. Then send that record instead of describing symptoms.
1. Log every dropout with a timestamp
Note the exact start and end of each outage. A line like “Tue 18:42 → 18:57, 15 minutes offline” beats “it drops every evening”. A connection monitor that records this automatically saves you from watching the clock.
2. Measure speed during the problem
Run a speed test while the issue is happening and record download, upload, and ping next to your advertised plan speeds. One test proves little; five tests across several days show a pattern.
3. Rule out your own Wi-Fi first
Test once on a wired connection or next to the router, and check whether one site or your whole connection is down (“Is it just me?” style check). ISPs ask this first — answering it upfront keeps the ticket moving.
4. Send one page, not a story
Put the outage timeline and the speed-vs-plan comparison on a single page: dates, durations, measured vs advertised, and your account details. Ask for a specific next step (line check, technician visit, or credit).
