Hey all

Hoping someone might be able to share some wisdom on this issue. 

I'm with Snap on their adsl2 plan (have been with them for years) and have lived in this unit in Massey for under a year. When i moved in and had it connected up it was great - my modem connected at 15mbps downstream and it's been fine since then up until the last couple of weeks i noticed major slowdown. I initially just thought with the Steam sale/holidays it could be congestion but it's been consistently bad this past week. I've restarted the modem numerous times ending up with the same results.

Now it's connecting at under 2mbps. I have'nt changed anything connection-wise, my modem/router is a linksys wag200g which i've had for years. I think i'm connected to the MSY/BC cabinet which is adsl2 and vdsl capable. Google maps puts me at about 200-300m from the cabinet (if i'm correct and it is this cabinet i'm connected to)

here are my current dsl stats:

DSL Status: Connected
DSL Modulation Mode: MultiMode
DSL Path Mode: Interleaved
Downstream Rate: 1501 kbps
Upstream Rate: 667 kbps
Downstream Margin: 9 db
Upstream Margin: 12 db
Downstream Line Attenuation: 22 db
Upstream Line Attenuation: 12 db
Downstream Transmit Power: 12 db
Upstream Transmit Power: 14 db

I'm can't remember what my line attenuation was before when download speeds were fine, i've had no issue in the past (as recent as last month) downloading at 1.1mbps through Steam and now i can barely reach 250kbps but i would think that the downstream rate should be better than this with even 22db?

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've got a wiring issue, have you logged a fault with Snap?

Do you mean an internal wiring issue?

Almost certainly.

There is a huge discrepancy between your attenuation and the sync rate you have.

Check PeterReader's post, and do an isolation test.
