I have NBN100 FTTH, have had for years. I normally get a solid 95/35 connection all day long, for the last few days from about 8pm onwards downloads speed drop to between 10 - 30 Mbps which is well below the typical evening speeds. I can run speed tests all day long and get 95 Mbps righ up until 8pm, have tried for the last 5 days in a row and consistently see the same problem.
Tried to open a ticket via the email helpdesk, just keep getting generic "We tried to call you" SMS messages, no missed calls on my phone, try to call the helpdesk and end up in an endless queue that just keeps getting longer and I give up. How do I actually get this fixed, I don't pay for 100 Mbps to get 10.
Have restarted my modem during the issue, makes no difference, have nothing else on my network using bandwidth, wired Ethernet directly into router connected to NTD.
