Recently connected to Vodafone NBN HFC. The Vodafone wifi hub works OK when stand alone as wifi router. Internet drops out repeatedly after one or two minutes when connected via ethernet to my desktop running windows 10. It appears the router tried to reset itself, connected, then broke again. Tried lan port 2, different ethernet cables, a second USB Lan connector, reinstalled network card drivers, network reset etc. but no success. The router works OK when connected to my laptop running windows 10 via ethernet. This rules out a faulty router and have to do some setting in the desktop.
Have anyone has similar experience and found any fix. Vodafone tech support was not very helpful in this.
Have you considered adding a wifi usb adaptor to your desktop and using that to connect to the modem?
