network #

Spectrum brings internet in via coax to their modem. The modem feeds the Eero (acting as gateway, handing out 192.168.4.0/24). Downstream of the Eero is the old Spectrum router still emitting an SSID on 192.168.1.0/24 — needs turning off (requires Spectrum admin access).

printer #

The printer was originally self-assigned static IP 192.168.1.165. After switching to Eero DHCP (192.168.4.0/24), it now gets 192.168.4.25. The admin desktop has a static rule configured for it, but the port config on the desktop still had the old 192.168.1.165 address — had to update it to point to 192.168.4.25. The port name is stuck as IP_192.168.1.165 (couldn’t be changed).

The DHCP-assigned 192.168.4.25 is subject to change — need to iron that out.

admin password reset #

  1. From the main menu, tap Counter → Display Keyboard
  2. Enter: stop, 0, 0, stop, 0, 1 via the on-display keypad
  3. A password prompt appears — enter: 9272 9272 9272 9272 (9272 × 4)
  4. Tap End (this is “OK”)
  5. From the new menu: stop, 0 on the on-display keypad, then C on the keypad
  6. This opens the admin password reset menu
  7. Set new password to: 12345678

NOTE: I put a sticky note on the side of the printer with these instructions

how to get to network settings #

After the admin password reset, I navigated through the menus to find the network settings and changed from static IP to Auto (DHCP). Didn’t write down the exact path — next time I’m at the printer I need to document it.

todo #

  • turn off “Olivet Bible Church” SSID on the old Spectrum router (requires admin portal access)
  • wall-mount Eero 2 to extend range to kid’s wing
  • consider getting a 4th Eero for Fellowship Hall coverage
  • set the printer to a DHCP reservation on the Eero so its IP doesn’t change
  • fix the shared password between OBC-Admin and OBC-Guest (currently the same)
  • re-run the damaged ethernet cable from the networking closet to the sanctuary
    • once done, plug blue #4 into the switch, feeding Eero 3 at the tech bar
    • Eero 3 can then feed Switch 3 for the tech bar devices
    • Eero 3 might be able to do this without a new run depending on strength of their back-haul
