The fixes for this were multiple.
1. After complaining to TPG i got upgraded to a 200Megabit connection which I have kept at $84 a month
2. I changed the default router that TPG provided to a Netgear AX5400 with 2.4ghz wireless
3. I eliminated the netgear hub in our lounge that wasn't a true 100 megabit just 10 megabit and just did everything via wireless.
4. We watch NBA league pass via an Amazon Firestick wirelessly.
The TPG upgrade did not make much difference but we kept it because of Covid lockdown and the number of family members working from home increased.
Changing the router out made a big difference because now instead of multiple routers and hubs we just rely on the 2.4ghz wireless. I downloaded and trialed a product called inSSIDer which showed that the default router wireless had very good throughput because they combined channels but that it dropped regularly. Whether that was because of interference with other routers daisychained in our very large house or other neighbours on the same channel, I don't know. Other Neighbours near me use netgear orbi and they rave about how good it is even some families share between parents and grandparents and only pay for one NBN connection. The only issue with the netgear router is that I had to speak to my wifes employers IT department in the UK about upgrading the wireless firmware on her HP laptop, they needed Admin access to do that.
The Amazon firestick is awesome but I tweak it a bit. I get all the standard apps abc,sbs,7,9,10,Disney,Netflix and NBA league pass* I install "Downloader" and wolf launcher as well as Aurora. With Aurora I can browse google play store apps for android devices that way I can load Binge and Kayo as well. I have to impersonate a specific amazon compatible android operating system in the aurora menu to do that also aurora is very hard to use from a navigation point of view. We have a Samsung TV and there is no league pass app for their Tizen TV operating system.
Now we have no more probelms with buffering but NBA League Pass itself is no longer the product it was in Australia. This season we have had odd games where there was no home commentary or the commentary was only in Spanish or Portuguese. It all came to a head during the allstar weekend when the Rising star games were locked out and the main game was only in Spanish and Portuguese. I found that by using an older version 10.2 of the NBA league pass app on the firestick I could watch everything ok but the newest version 10.4 would not work. Fun and games. We have been league pass subscribers for 3 years and it was really good for the first two years when Neulion was in control but this season has been **e so we probably won't renew. It's like the nba.com domain which redirects to sporting news in Australia and you have to click through the link on that page or setup a html header to change your Forwarded-For ip address or have a US VPN to get to the real NBA webpage even then sometimes you get a 502 bad gateway error.
The AUS market is just too small for NBA and they just subcontract it out to someone who tailors the content for Australians by presenting articles and video highlights focusing on Australian players or teams with a lot of Australians. The team I follow doesn't have any Aussies playing and I think you'll find that with 30% of Australians having been born overseas and half of us having at least one parent born overseas there is no particular bias in viewership to only want to watch Aussies. Having said that Giddey is Good and at 20 is set for a long career and I also like to watch the occasional Patty Mills or Joe Ingles highlights but I can find that for myself.
Hope that helps
