I have recently signed up for Naked VDSL and am getting crap speeds, quite variable but usually between 2-10Mbps download to a local speed test server and usually worse to international servers. My modem however syncs with a line speed of ~58MBps suggesting I have a reasonable line should be able to get better than this. Slingshot support have been reasonably responsive but after going backwards and forwards with them for the last two weeks I seem to be getting nowhere and after their lastest reply it has me wondering if I might be better getting someone more technical or more interested than their 'tech support' to take a look at my issue.

The latest reply was they have reset 'my profile' so I need to wait another 10 days to see if speed improves...
Seems like an odd idea to me since I was a new connection anyway, my modem line rate was good and I wasn't seeing any reconnections so my logic (im no expert) would suggest it is unlikely a profile issue but so be it... That was on Monday and my speeds haven't changed so I doubt they will improve any further.

Below is my modem stats and a typical speed test - interesting to note that sometimes my upload is faster than my download?
Corus did install a splitter on my insistence but didn't change any of the jackpoint wiring, it is still the old 4 core type telephone cable that connects my splitter to the VDSL jack - again though my line rate is good so I think that is unlikely the issue.
I'm connected directly to the modem via Ethernet cable, only the single PC connected to the Modem. Have tried 2 other PCs, different cables etc. I also tried briging the modem to another router to eliminate the slingshot router function.

So any advise from any of the smart geeks on here? Any help from a Slingshot Rep?

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?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

I assume you're testing over Ethernet, and not WiFi?

Yes I did mention in my original post that Im connected directly to the moden via Ethernet cable and there are no other Pc's or devices connected to the modem/router.

have you tried a standard http download?

see if maybe your having issues with flash not being able to keep up?

your linestats look to be a pretty nice 17a sync. Ild try to avoid reboots with that....

I have confirmed the speed tests are giving a reasonably accurate representation, verified using known fast downloads etc.

Bumping for any further thoughts or perhaps a Slingshot rep can follow up?

Looks like a throughput issue. They aren't easy to solve and Slingshot will be emailing you a whole swag of tests to do including trace routs to various websites, ping tests and other information before they will look at anything else.

Your physical results look good and definitely don't match what you posted from their website. If you've tried another computer and other cables, have you tried different ports on the back of the modem itself?

And yes, avoid resetting your modem. You have the golden cabinet profile!

Yes, I done all the trace routes etc for them 2 weeks ago (or was it 3?), that's why I'm posting here because they don't seem to be doing anything apart from "reset my profile" which obviously doesn't seem to be the problem.

If you've done all the leg work, you need to make more noise, or try and find another VDSL router to try out. It's probably going to be a pain in the arse however, considering VDSL isn't very popular.

I remember way back when finding another modem to test was almost impossible, because they cost hundreds of dollars and nobody wanted to lend you one! It's back to square one with VDSL modems now, haha :)

Hopefully Chris from slingshot will pop in and push this to the right people for you.

Sounds like you have been dealing with front line support who will simply go speed issue? oh must be the dsl connection. Clearly in your case this is not true and congestion or some sort of profiling is causing you issues.

Bit late to the party here sorry! OP are you able to flick me a message with your account number. If you've still got those tracerts on you that would be ideal too.
