That’s kind of you thanks and thanks for spelling out NOC. I’m guessing my issue isn’t showing up on ping tests and getting me to ping their own site, iinet.net.au, has just confused everything. I’m willing to bet if you or anyone else were to ping that site you’d get the same result, 100% packet loss. Megared17 in another comment thread was able to let me know it’s actually an Amazon server so it doesn’t pertain to them, or me at all. Megared17 also suggested interference from neighbours but in trouble shooting with iiNet I’ve already switched channels twice and turned band steering off. I’ve seen the rapid speed drop occur while connected to Ethernet too. I’m thinking the only remaining explanation is the physical line to the node. They have told me it’s achieving 88 Mbps (I pay for 50 Mbps and get this most of the time except when it loses its mind and drops and kicks us etc). The line to the node is copper. Not much I can do about that. If that’s the cause of the problem then switching ISPs isn’t going to help.

Is there anything else that might explain seemingly random lag spikes and speed drops that last around an hour and occur in peak and off peak times? Also occurs when everyone is using devices and when only one or two are. Do devices sitting doing nothing but holding a connection present an issue (at random) with connection quality?

I should have mentioned, 1.1.1.1 pings absolutely fine.
