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

Are you using line filters or do you have a master filter installed?

It can infact, make it worse. DLM dynamic line management.

Will auto adjust based on noise etc to the best and potentially slower/more reliable profile. Trigger it too many times and it will always put you down subsequently - hence above question

Look at getting a dedicated xDSL jack point and master filter installed first by @coffeebaron if he is local to you

Looks like a HR fault based on your description.

This could be caused by say, water ingress into a join, slowly getting worse to the point that it's started failing.

Likely you will find temperature/humidity will also affect this.

Give your DSL cable etc an unplug switch it out of possible and see how that goes. Past there, Likely yes a field tech will be required.

Typically this is Not caused by a faulty modem, that's a horrible misconception out there...

On the front of charges, when managed correctly this should be in about the 5% chance, which can be reduced a bit more with correct management.

Ultimately chorus fieldtechs can be a bit of a coin-toss, Especially in visionstream areas :/

I can't really speak for your previous experience without knowing all the details so excuse the somewhat broad analysis.

Thanks Oblivion,

The description does fit our issue. Stable 5 Mbps DL and 1Mbps UL is definitely not enough these days lol. Thanks again for your help

Thanks Hio77 for your suggestion.

It does seemed the issue gets worse in bad raining days :S.

I also agree with that it's 50/50 with Chorus tech. Once our internet and phone line was down and a chrous agent came in while we were away and said cant find problem. We complained to Chorus and they sent a different tech and he found a broken line immediately and he was shocked that previous tech didnt see it as it's obvious :S.

Bingo, Raise a fault.

Orcon will likely go through 24hour LQD before logging, this will simply give you more supporting evidence.

When raising it mention that it seems to get worse with weather, this is a flag that can be fed through to chorus to help them narrow things down.
