Hi guys.

When we first signed up for our VDSL2 service from telecom, and for a long time afterwards, I had a constant sync rate of around 40mbps.

Now lately, for the past few months, I've been syncing at 28mbps, and I haven't seen it go higher in a long time.

My upload speed has remained unchanged however.

Is there any way, a techie can look into my connection, to restore my line to it's original, if not better speed?

Nothing major, but my pings are fairly high 39mbps to trademe, and 376ms for google.com.

Is there any way for a techie to put me onto a faster line profile?

Thanks

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?

Has your speed dropped if you do a speedtest (on the Telecom page)?

How long was it faster for?

The more people who sign up for VDSL the worse it will get due to how the technology works. Especially not helped by folks who don't get a master filter.

Happy to run a line test but it doesn't bode well.

Unrelated to your physical line issue (which is PL mentions is just something that happens as more people on bundles close to you get VDSL) but if you are getting 376ms RTT to google.com, you're probably using the wrong DNS servers. Make sure you use the automatically assigned DNS servers.

do you have a master filter? has anything been done to your wiring recently?

vdsl is a best effort service, they cant change your profile or DLM, but maybe a rest will help

i wouldn't hold your breath on getting back to where you originally were speed wise

It will take a week or so for your speeds to reach close to the optimum.

As I mentioned in another thread my VDSL speed has also dropped, by about 30% or more for me.

He means are you using a ethernet/lan cable to connect to the modem from your PC.

Also sync speeds can improve or they can stay the same depending on your line stats but they'll change and it would of done the core DLM training by the 10th day. So first results isn't always the best or worst case they can improve it's just a waiting game.

Yes using a cable. Been on VDSL for 6 months enjoying great speeds. Dropped significantly a week ago with no change so far.
