ISPs advertise “up to” speeds. Your real-world result depends on line type, congestion, modem and Wi-Fi. Use NetStartr to find out what fraction you\'re getting.

How to test your Spectrum (Charter) connection accurately

  1. Plug a laptop or desktop into your router with Ethernet (avoid Wi-Fi for the headline number).
  2. Pause cloud syncs and downloads.
  3. Open NetStartr and click Start Test.
  4. Pick your Spectrum (Charter) plan from the “Am I getting what I pay for?” selector and read off the percentage.
  5. Re-test at peak (8-10 PM) and off-peak (8 AM) to spot congestion.

What to do if Spectrum (Charter) underdelivers

  • Reboot your modem & router; many ISP modems re-provision on boot.
  • If you\'re under 70% of plan three days running, contact support and reference the times you tested.
  • Ask for a free modem swap (cable plans) or a tech visit.
  • If unresolved after a few weeks, request a partial bill credit.
