There are several NBN ‘technologies’, thanks to political butchering of the whole thing, which makes it harder to suggest solutions.
Basically we have:
FTTH (fibre all the way) - best there is, period.
FTTN (still uses copper to deliver VDSL).
FTTC (like FTTN only much less copper).
HFC (using pay TV cables; aka. Cable internet).
Fixed Wireless.
For FTTN connection you need to remove all phone points but one. Actually, get a cabler or sparky to come out and rerun the phone line from the entry to your house to your chosen outlet point - makes a huge difference for FTTN connections, though sadly the copper running the rest of the way to the node is a pile of rotting crap.
Bojan suggests he has a HFC connection, so this won’t help him at all.
Bojan, the problem with HFC is that it is a shared medium, with everyone in your ‘local loop’ sharing a limited amount of bandwidth. This means if all your neighbours are furiously downloading, you will be throttled to death. ADSL (and VDSL, so FTTN and FTTH) don’t have the same design, so your ADSL bandwidth is from the exchange to your house was all yours. From the exchange, you shared the backhaul with everyone else, but that was in the order of gigabits/s, so you wouldn’t likely notice.
Then there is the way NBN sells capacity to ISPs (called CVC). So iinet would buy so much bandwidth to use in NBNs backhaul, and that is shared among all iinet users in your local area (which could be 100,000s of connections). Too little CVC for peak demand and you and your fellow customers end up shafted. It is common for ISPs to under-purchase CVC - the two ISPs known for over-purchasing CVC are AussieBB and Telstra.
Probably too late to change any of this mess, but the geniuses that came up with this digital train wreck did just call an election...
So, it could be your PC has issues. It could be all your neighbours decided that it was time to download the latest Game Of Thrones about the same time. Or it could have been everyone on iinet in East Melbourne wanted HBO and dragons with their breakfast. Or a combination of all of this.
Hard to troubleshoot without being able to look at your network and machines, but I’d suggest you reset your router to iinet factory settings, then change the DHCP settings in the router to the cloudflare DNS servers (or Google’s if your prefer them). Then on your PC set the network options to purely get everything from DHCP - basically testing to see if there is a setting someplace that is causing problems (ie. it’s your computer’s fault) by making the router tell it exactly what to do. Then see if that works. Feel free to unplug/replug your network cables, or replace them completely.
Worry about things like reserving IPs (or static IPs) when you have solved the problem or eliminated everything else. Going manual on your home network config is a possible source of problems unless you know exactly what’s what.
At least you are not on fixed wireless. That’s a service that is well and truly stuffed. Oh, and every time we get heavy dew and condensation getting into my rotting copper feed my FTTN turns into a yo-yo, so I have a hate-hate relationship with my FTTN service - so we all suffer in some way.
