Hi guys,

So as of late I seem to have noticed my speed seems to be slower than it used to. AFAIK my line stats seem ok(?)

I've just switched over from Vodafone to Telecom for the 500gb plan. I got the Thompson router with the package and have now plugged it in to test speed (reason being I've had a linksys WAG200G for about 6-7 years now that I have wondered many times, whether or not it is dying.) I've been having D/Cs quite often, from around 11pm onwards which I haven't been able to isolate whether it was just the router or not.

Details below.

Link Information

Uptime: 0 days, 0:31:09
DSL Type: ITU-T G.992.5
Bandwidth (Up/Down) [kbps/kbps]: 696 / 8.220
Data Transferred (Sent/Received) [MB/MB]: 22,40 / 208,21
Output Power (Up/Down) [dBm]: 12,6 / 0,0
Line Attenuation (Up/Down) [dB]: 20,0 / 34,5
SN Margin (Up/Down) [dB]: 12,8 / 11,3
System Vendor ID (Local/Remote): TMMB / ----
Chipset Vendor ID (Local/Remote): BDCM / IKNS
Loss of Framing (Local/Remote): 0 / 0
Loss of Signal (Local/Remote): 0 / 0
Loss of Power (Local/Remote): 0 / 0
Loss of Link (Remote): -
Error Seconds (Local/Remote): 1 / 0
FEC Errors (Up/Down): 0 / 60.475
CRC Errors (Up/Down): 0 / 1
HEC Errors (Up/Down): 0 / 2

For the past couple of months my speeds have been very slow, I used to get 8-9Mb/s on speedtest. Lately it has been anywhere from 3-7Mb/s.

I've changed the line from the jack to the router. I have a dedicated jack so I don't use line filters. What are my next steps to see if Something is wrong with my connection?

Also I live around Market Rd in Epsom, western side of the motorway, Probably somewhere around 1-1.5km away from the remuera exchange.

Appreciate any help.

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?

With an Attenuation of 34db, you really should have a Master Filter.

If you pm me or email me pl @ I will run a line test, and say that you will need a Master Filter.

Ditto, a Master Filter is recommended if you want to get the most out of your DSL connection.

Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?

Already run a line test, yes he needs a master filter and he may be in contact soon for some of your loving.

Coffeebaron came over and changed out the existing master splitter and rewired a direct jack from the splitter I gained a little bit of speed both ways. new line stats below.

But the connection feels very unstable just wondering if this is just normal and I have to live with it. Streaming anything in HD isn't smooth, 1080P youtube requires a bit of buffering. my iptv box also requires a lot of buffering.

I've tried calling telecom a few times, but they keep telling me line tests are all fine, there are no faults on the line. Keep asking me about routers and interference. I have tried 2 different routers with pretty much same results.

I am aware because of where I live this may be about the max I can get, but is there anything else I can ask them to check or do to try improve? I know that each ISP is slightly different, but this is definitely worse than vodafone. Problem is I signed a 12 month contract so I have no option but to stick it out.

See if you can get a port change.

Master filter didn't make any difference to my internet performance. I had heaps of fec errors, and others like you have above. After port change it is now near 0 a day.

Also try couple days without wifi, as radio interference can cause errors, just rules it out. I've noticed fec errors etc go up when microwave oven running.

They also changed line from exchange to my house, don't know if that was the cause, but it's all running good now.
