Internet Slow Only in the Evenings? It's Probably Not Your Router

Fine at noon, crawling at 8pm — congestion vs throttling vs failing hardware, and the tests that prove which.

  1. 1. Test wired at peak and off-peak

    Run speed tests over Ethernet at 8pm and at 8am for two days and screenshot both. Evening-only collapse on wired = congestion or throttling, not your Wi-Fi — no mesh system fixes the street, only your house.

  2. 2. Compare with a VPN running

    Run the evening test again with a reputable VPN on. Faster through VPN = your ISP is throttling video traffic specifically. Same speed = general congestion on your node.

  3. 3. Call the ISP armed with numbers

    Report with dates, wired tests, and modem signal levels (from 192.168.100.1 on most modems). 'Slow internet' gets a script; '70% packet loss 8–10pm three nights running, here are screenshots' gets a technician.

Internet Slow Only in the Evenings? It's Probably Not Your Router — When to Call a Pro

  • You need the full documented case built — tests, modem stats, and the escalation path.
  • Evenings are business hours for you (streamers, remote workers) — failover internet planning.
  • The modem is 5+ years old — weak hardware collapses first under peak load.

Guide FAQ

If the node is congested, no — a bigger slice of a jammed pipe still jams. Fix or switch the connection before upgrading the plan.
Video throttling is documented practice on some plans. The VPN comparison test is the honest way to find out in 10 minutes.
