Starlink fails to connect (RUT240)

I posted previously about issues I was having (Starlink connection not detected - resolved by reboot - #3 by Marijus) and the suggested solution was to disable IPv6. This didn’t fix the issue, and I was unable to reply with an updated troubleshoot file.

I have since changed my Starlink modem to StarPower 12V - Stralink DC Power Supply - SpaceTek Shop Australia which works perfectly with a USB modem and also on the WAN port of a Grandstream router, but I can’t get it to work at all via the WAN port of the RUT240.

I have updated to the latest firmware (RUT2_R_00.07.06.12) and reset all settings.

Can you please send me a request for an updated troubleshoot file?

Hi. I emailed a troubleshoot file, but have not heard back.


Sorry for the delay. I reviewed your troubleshooting file and it appears that the Ethernet WAN is not connected. Only the mobile connection is active.

Could you check if Starlink is providing an internet connection through the Ethernet port by plugging it into another device with an Ethernet port?

Additionally, the WAN port on the RUT240 router might be faulty. Please check this by connecting another router or Ethernet source to the RUT240’s WAN port.

Best regards,

Thanks for the response. The Starlink works when connecting the ethernet cable direct to my laptop.

I’ve tried sharing the wifi from my laptop over ethernet to the WAN port, which also shows up as no connection. Perhaps it is faulty.
