Hey everyone.

Experiencing very slow broadband speeds with Slingshot and was wondering if anyone could provide any tips on things to check/call about etc. I have recently moved to the Beach Haven area a short distance off of Rangatira Road and am currently only getting 190-220KBps. Here are the things I have tried:
-Isolation testing - Swapping out all cables and testing different devices.
-Speed testing - Using online resources to test packet drops etc. (All good but with indications of very slow speeds)
-Throughput testing - Used Slingshot's script to test throughput, this hung on a loop of tracert commands that never completed after long periods of time.
-Manual tests - Pings etc. to try and determine the source of slow speed. (All returned very fast except for the ping to Slingshot servers, these all timed out) If anyone has any ideas, or if there is someone from Slingshot on this forum, any input would be much appreciated.

Thanks.

EDIT: To add some of the details pointed out by the bot.

 

ISP Plan: Slingshot Unlimited Broadband
Type of Connection: ADSL2
Modem DSL Stats: Down=2345Kbps Up=1116Kbps
General Location: Gemini Place (Off of Rangatira Road in Beach Haven)
Rural or Urban: Urban
Exchange/Cabinet/Conklin: Don't know

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?

Can you post line attenuation and noise margin from the modem as well please.

Your throughput s consistent with the speed the modem is syncing at, but it is very low for an urban area

your throughput of 220KBps matches your sync speed of 2200kbps so in that respect there is nothing wrong.

we need the rest of your modem stats, that includes the attenuation and the SNR.

you are exchange fed from the birkenhead exchange.

your speed is rather slow. what is the wiring like in your house? Are you able to disconnect all other devices plugged into phone jacks then test again? what about seeing if you can find the ETP or the master/first jack point and test there to try eliminate the rest of the houses wiring

As pointed out by others you're connected directly to the Birkenhead exchange and are in a 10Mbps + area.

Your speeds are exactly what your DSL sync is showing so in that respect nothing is wrong. Your issue is that your DSL sync is significantly below what it should be, and the most likely cause of this is poor internal wiring within your house.

Please provide the DSL stats from your modem as requested above.

6dB margin so you are on callplus gear at the exchange so should be getting heaps more than that.

Sort the internal wiring out and see how it improves. If not then get a fault raised with chorus via the slingshot call center.

my suggestion would be to get a hold of coffeebaron and get him to install a master filter and sort out your internal wiring, if things dont improve from that then do as Rich said and egt a fault raised with your ISP.

That 44dB downstream attenuation suggests a very long line to the exchange. With the 6dB noise margin, as others have pointed out, you are probably on Slingshot's ULL gear in the exchange.

I'd suggest you may be suffering from midspan injection, where a ULL line from the exchange actually passes through a nearer cabinet. The solution is to ask for SS to move you to a Chorus connection instead. This was a common issue a few years ago as new cabinets were put in, but ULL connections left back to the gear in the exchange - not very common any more though.

Check the Chorus website to see what speed connection (>10Mb/s or >20Mb/s) it says for your address. If you are in a small polygon area (not the big area surrounding the exchange), this will be fed from a cabinet - you need to get your connection moved to the cabinet.

EDIT: @sbiddle wrote an excellent blog on this a few years ago - it still applies. http://www.geekzone.co.nz/sbiddle/7872

It's at the end of the exchange reach. Bit further down rangitera and its into cabinet zones.

Doh! Missed the street name in the OP. Means it isn't midspan injection. Is 44dB attenuation about right for that area, or too high?

Back to basics then.

Isolation test as per the links from @peterreader's post, and look to installing a master filter.

Hey everyone, thanks for all the assistance, I'll be looking into getting the wiring sorted if the next thing I'm trying doesn't solve the speed issues. So my flatmate knows a Team Leader in Slingshot and he said it seems like it needs to be put on a different cabinet and he'll be sorting that first thing tomorrow. I think with that and all the things you have all suggested it should be resolved as best as it can, so this will probably be it from me for now.

Just wanna add that you all on here have been more helpful than every person I've ever dealt with over the phone related to ISP's, be it a tech or a support person. So thanks everyone!

EDIT: In case the things tomorrow don't sort it, the chorus website has shown I am in a >10Mbps area. I will definitely look into the master filter and wiring suggestion, I was just hoping it would be a much simpler fix than that. tongue-out

Just wondering why the ISP techs you've been dealing with wasn't very helpful. This looks to be a very basic DSL fault.

The diagnostic is to compare the current sync rate to the prequal results, which takes only a few minutes.
The fix is give customer advice regarding internal wiring, and if that doesn't help, get Chorus to roll a truck.

What could go wrong in the process?

I really wonder that myself. The people I have dealt with over the phone have been very slow, seem to have next to no idea what they're talking about as they pass me around through different teams and "consult support teams" multiple times to simply tell me there seems to be an issue and then simply log a fault for Chorus.

Not sure if it falls down to them being on an off day, not trained well enough, or just not thinking at times. But I've found what I've gotten from this forum to be more information than I got through a 40-60 minute conversation being put on hold multiple times and met with an uncomfortable silence over the phone while the guy was not sure what was going on.
