Hi,
I'm looking for a 4g plus modem with ethernet (to connect a thermal printer for my business), but I don't want to pay $250 for a modem provided by Optus as it is a temporary solution (1-2months).
I'm on a month to month contract, $70 for 100GB (50+50).
I just got the $70, 100GB month to month too and just bought the Optus 4G Plus modem from Officeworks for $45. You can buy a range extender with ethernet port from Kogan for $25 delivered. Might be your cheapest overall solution. https://www.kogan.com/au/buy/universal-wi-fi-range-extender/
