Hi,

I've had VDSL from Snap for 2 months now and my sync rate used to be 15.5Mbps RX 9Mbps TX (attainable data rate ~12.8Mbps RX 9Mbps TX).  After Telecom came and done something to the phone lines next door (for 12 sub divisions) my sync rate has dropped to 12.6Mbps RX 7.8Mbps TX (attainable data rate 10.3Mbps RX 8Mbps TX).

I have P-870H-51A V2 modem and here are the xDSL statistics:

VDSL Port Details Upstream Downstream
Line Rate: 7.892 Mbps 10.296 Mbps
Actual Net Data Rate: 7.857 Mbps 10.247 Mbps
Trellis Coding: ON ON
SNR Margin: 12.0 dB 12.2 dB
Actual Delay: 0 ms 0 ms
Transmit Power: 7.8 dBm 12.3 dBm
Receive Power: 3.0 dBm 3.7 dBm
Actual INP: 0.0 symbols 0.0 symbols
Total Attenuation: 6.1 dB 8.5 dB
Attainable Net Data Rate: 8.000 Mbps 12.696 Mbps

I am wondering, does everything (except the data rate) look alright and is there ANYTHING I could do to improve this?  We don't have the filter installed as we only have 1 phone jack.

Thanks in advance.

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?
