Hi

I have noticed a significant speed drop since switching to the unlimited plan.

It has been like this for a few days, so wondering if it has been throttled back or is there some other network related issue?

Modem DSL Information shows

DSL synchronization status: Up

Connection status: Showtime

Upstream line rate (kbit/s): 9446

Downstream line rate (kbit/s): 33640

Maximum upstream rate (kbit/s): 9472

Maximum downstream rate (kbit/s): 33728

Upstream noise safety coefficient (dB): 11.9

Downstream noise safety coefficient (dB): 12.1

Upstream interleave depth: 0

Downstream interleave depth: 0

Line standard: VDSL

Upstream line attenuation (dB): 0

Downstream line attenuation (dB): 0

Upstream output power (dBmV): 0.1

Downstream output power (dBmV): 13.5

Downstream interleave depth: None

I was getting higher test speeds than this before, with up to 9Mb's upload speed.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

guess what? you modem is connected close the what the bottom speed test is saying there doesn't look to be any major drop in speed at all

did you take the top speed test over a wireless connection? try using a few different speed test servers, im on telecom and find i get a worse result to the telecom server than to others

Hi

The second speedtest is before I switched to the unlimited plan. The first test is quite a difference from the modem connection speed. I have tried numerous servers with the same results. Which is what has lead to the question whether my speed has been throttled.

Doubt it but possible. We did change the billing profiles and defined ADSL plans to VDSL plans for this exact reason.
PM me your details and ill take a look when im in next.

you didnt answer this question

did you take the speed test which shows the slow result over a wireless connection or with the computer/laptop connected to the router with a Ethernet cable?

Not sure what the relevance is of whether it was done on a fixed or over wireless. Both results were on the same computer on same router and in same location just at different times.

How ever I have tried on both fixed and wireless and still get similar results.

Issue on our end. I got some progress on it but it seems a few people have the same issue and migrations are taking place to fix it soon.

Cheers

because wireless will pretty much always give lower results and over a Ethernet cable

hence the question

there has been many a person coming on here complaining that their VDSL/UFB isnt preforming and it turned out they were testing over slow wifi. unless you have the latest cutting edge wifi you are unlikely to ever see the line speed of your VDSL/UFB connection.

WiFi uses public spectrum so it's a free for all and if your neighbors are using the same WiFi channel then speed goes down hill

How is the speed now? Please do not test WiFi

Thanks JohnR.

I have a Wifi Analyser program so I know that there is no other wifi signal anywhere near my channel. But thanks for the feedback.

Speed has certainly increased since TimA looked at the issue and fixed the problem, my speedtests are now as below.
