I was so sick of the ever deteriorating NBN service, where I was paying for 50 down and 20 up, but getting 20 down (If lucky) and 2 up, that I cancelled it and threw it in the recycle bin. The network provider blamed the copper lead in cable, not so, it's a cop out. In off peak periods, like the middle of the night on Christmas Eve, it was great (so stop blaming the cable section). No the problem is congestion, all these work from home people, businesses hogging bandwidth, and providers giving bandwidth priority to big payers. It comes down to lack of sufficient network capacity, load shedding, and Mux programming decisions.
So i scrapped dealing with any NBN related service. This is after trying out my 5G phone as a Hotspot. Good 5G coverage in all the places I go, why not go wireless. Even on the phone hotspot my performance was wonderful.
So during the Boxing Day sales I bought (from the Good Guys) a dedicated multi device Hotspot, the Inseego Mifi 5G Pro. I can report it is a wonderful device and does everything I want, runs simultaneously everything I have, including 4k streaming services. Speed test reveal over 90 meg down and 50 up, with four devices working, during the daytime. Battery lasts all day in constant use, and recharges quickly. Obviously, performance can vary, and I live in a regional area, but for now it was a good choice.
You will need to get a 5G SIM to stick in the Inseego, but there are cheap work arounds, depending on your area, for example: I am currently using a Boost pre-paid SIM (which uses the Telstra network), which i had in my backup phone. It runs 5G, because that is what Telstra is using in my area, elsewhere it might default to 4G, but I need to test that.
PS, the Inseego will have paid for itself ($399) after four months, which includes the refund I got from Aussie Broadband for cancelling. Longer term I will move to a Telstra 5G SIM which gives me data sharing feature between my phone and the Inseego.
