How to reset a ARRIS / Surfboard router

More detail: how to reset your router.

192.168.100.1 not opening? Fixes that work

  • Connect to the router first. Use its Wi-Fi or a LAN cable — mobile data will never reach 192.168.100.1.
  • Type it in the address bar, not the search box, and include http:// — http://192.168.100.1. Many routers have no HTTPS page.
  • Check for typos: only numbers and dots. The letter “l” or “o” in place of 1 or 0 will not work.
  • Your router may use a different address. Check the default gateway (see above) or the label.
  • Turn off VPN, proxy or “Private Relay”. They send traffic outside your home network.
  • Try another browser or a private window, and clear the cache.
  • Restart the router: unplug it for 30 seconds, then wait two minutes after plugging it back in.
  • Still stuck? A factory reset restores the default address and password.
