I signed up unlimited VDSL with Orcon last November and everything was working fine except odd disconnection once or twice a month. I didn't mind as it was a lot worse when I was with Spark. One of reason we tried different ISP i.e. Orcon

However, this month I have experienced massive speed drop from ~35 Mbps to 5Mbps Download (Ookla peed test), but no disconnection. Restarting my D-link router does not help, but restarting Orcon NF4v Modem solve the issue temporarily. At beginning of month I will need to restart modem 1 or twice a day, and yesterday 1 or twice an hour. It looks like it's issue with modem, but with Orcon I am unable to swap it over with my own modem to test.

Contacted Orcon, but they want to contact Chorus to check line. We had Chorus to check the disconnection issue when we were with Spark last 2 years. We paid 4 or 5 times totaling more than $500 and the issue was not solved. In addition, The internet was working okay the first 3 months thus not too keen to try Chorus again. Orcon also suggested that could be internal line issue, which could also be a possibility. However, could restarting modem resolving speed issue that's caused by internal line?

I have also include the diagnostic test I done.

I did a search on geekzone, and there was someone with similar issue, but the it was closed and no solution. Just wondering if anyone experience the same issue or have suggestion what the issue would be. Thanks again in advance with all your suggestion and help.

Kind Regards

James
