Cable (DOCSIS 3.1)
Mediacom Speed Test
Mediacom provides cable internet to smaller markets across the Midwest and South, with plans from 100 Mbps up to 1 Gbps. Mediacom plans carry monthly data caps that vary by tier, and like all cable, upload speeds are a fraction of downloads — two things worth knowing before interpreting your test.
What speeds should Mediacom deliver?
Wired downloads should land near the advertised tier — 100 Mbps to 1 Gbps by plan. Uploads range roughly from 10 to 50 Mbps depending on tier. Evening slowdowns beyond ~20% suggest local node congestion.
Mediacom's data caps range by plan; heavy households on lower tiers can hit them, adding fees. Slow tests don't indicate cap issues (Mediacom charges rather than throttles), but the app will show your usage.
Slow Mediacom speeds? Try this first
- 1Power-cycle the modem before troubleshooting — stale channel bonding is the most common fixable cause of slow cable speeds.
- 2Verify your modem (rented or owned) is DOCSIS 3.1 if you're on a gigabit tier; older units cap throughput hard.
- 3Track usage in the MediacomConnect app if you're on a capped tier — overage fees sneak up on streaming-heavy homes.
- 4Wired tests that match plan speed while WiFi lags mean it's time to reposition or upgrade the router, not the plan.
Mediacom speed test FAQ
What speeds should Mediacom deliver?
Close to your advertised tier on a wired connection — plans typically run 100 Mbps to 1 Gbps down with 10–50 Mbps up. WiFi results will be lower, especially away from the router.
Does Mediacom have data caps?
Yes, Mediacom plans include monthly data allowances that scale with tier. Exceeding them adds overage charges rather than slowing your speed.
Why is my Mediacom internet slow at night?
Cable nodes share bandwidth across neighborhoods, so peak evening usage can slow speeds. If evening speeds fall by more than about 20% consistently, report it with dated speed-test results.
