Topic # 138337 30-Dec-2013 20:59 Send private message


Since last few weeks , I am experiencing extreme slow internet speed with SNAP. My modem is connected to first telephone jack  where wiring enters into my house.

My exchange is around 2.5 Kms away from my house

Following are my lines stats

Uptime: 0 days, 20:27:47 DSL Type: ITU-T G.992.5 Bandwidth (Up/Down) [kbps/kbps]: 745 / 1.319 Data Transferred (Sent/Received) [MB/GB]: 989,42 / 1,47 Output Power (Up/Down) [dBm]: 12,6 / 0,0 Line Attenuation (Up/Down) [dB]: 22,9 / 45,5 SN Margin (Up/Down) [dB]: 13,6 / 22,3 System Vendor ID (Local/Remote): TMMB / ---- Chipset Vendor ID (Local/Remote): BDCM / IKNS Loss of Framing (Local/Remote): 30 / 0 Loss of Signal (Local/Remote): 11 / 0 Loss of Power (Local/Remote): 0 / 0 Loss of Link (Remote): - Error Seconds (Local/Remote): 481 / 27 FEC Errors (Up/Down): 208 / 0 CRC Errors (Up/Down): 325 / 3.385 HEC Errors (Up/Down): 0 / 11.684
Appreciate any help to  have this resolved.

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?

45 db attenuation is quite poor and suggests you have 3.3km of cable to the exchange - suggest you get your wiring looked at to try and squeeze out as much as you can.

With sync stats and attenuation like that it's not surprising your speeds are slow.

The first step is to eliminate your internal home wiring. How many other jackpoints do you have?

This is the only Jack point in the house.

hemantdb: This is the only Jack point in the house.

Get the wiring looked at when you can. I cant remember where but a certain area in Epsom has terrible wiring on the street.
Log a fault with your Snap or get a private contractor to have a look.
