Hi, I currently have a case open with Vodafone (since Wednesday) as I am having issues with slow speeds and packet loss.

Steps so far;
Tried 3 different devices (laptop-ethernet/phone-wifi/desktop-wifi)
Tried a different router (currently using a Vodafone HG556a)
Different filter (only one jack point physically wired)
80GB ADSL plan and no limits according to Vodafone
Vodafone 1st level checks/changes (I got them to do a port reset just in case)

It went to Chorus and they said the line is fine, which I am assuming was only checked at the exchange end as no one visited. So went back to Vodafone faults team and they did a 24hr line check and said they could see some faults. Chorus guy came this morning and checked house wiring and ran tests and they were fine. He even replaced the jack point as it was a really old one.  

Speed test. Normally 6-7Mb/s down, ping and up are about right.


WinMTR Statistics to Trademe

Similar on everything else, starts loosing packets on (Dunedin?) Anyone else in Dunedin having issues?

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?

So was still bad Sunday evening/Monday morning but magically came right Monday arvo. Called Vodafone to see what changed and they said nothing and that the job was closed off at Chorus and their end (unsure why as it wasn't fixed). So no idea other than a routing change or took a while for line to sync correctly after jack replacement (doubtful).

johnr: Or copper cable is drying out after all this rain

That rain did quite a number on my DSL line too. Oh well can appreciate that it came and now it's left.

There are a few things it could be.
- Uplink saturation.
- High error rates on line (Rain can cause this)
- Modem could be over loading and is causing it to congest traffic and load up CPU/Memory
- Somewhere along the network one fibre line could have died and was using a redundant one and causing it to congest. 

If it has been fixed thats great. Otherwise isolate the modem first and make sure there isnt any unwanted traffic taking up the network.

When I tried the other modem there was only the one device on it.

As for the rain being an issue, its possible. I would have thought we would have seen symptoms though like:
noise on the phone line
low line sync rate
issues on the Chorus guy's line check
change in ping

It just seemed like a through put issue on one of the nodes in the routing at the time, but its fixed now so all good.
