Over the last few weeks I have noticed my web browsing speeds seemed to up and down. I started to do some speed tests using Slingshots Internet speed checker.
Here is one of the average readings I have been getting.

Download Speed: 3697 kps (462.1 KB/sec transfer rate)
Upload Speed: 682 kps (85.3 KB/sec transfer rate)
Packet Loss: 0 %
Jitter: 24 ms
Latency: 772 ms
Test Server: nz-akl

Latency figures have been as high as 1400 and as low as 20. The 20 reading was my normal figure. I have talked to Slingshot, and although the guy I spoke too said something didnt seem right he couldnt pin my erratic readings down to anything in particular. He suggested my router could be faulty, to try another one then call them back. If only I had a spare adsl2 router lying around, but I don't. Unless there is someone from Timaru on here who has one I could borrow. Below is what my router is currently reporting for connection, which seems to be my normal speeds. Is it likely my router is faulty, or does someone on Geekzone have a different opinion.

connection speed downstream 20815kbps, upstream 1065 kbps
Line attenuation downstream 5.0 db, upstream 3.9db
noise margin downstream 11.7 db, upstream 12.5 db

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.

you have checked your not saturating the link? torrents seeding or something?

testing over ethernet or wireless?

Only program open is my web browser and testing over ethernet.

Do a bit more testing on the command line....
Run 'pathping trademe.co.nz' and paste the output up on here.

Also run a 'ping trademe.co.nz -t' for a little while to see how much it really does fluctuate.
