Problem with router, ISP or BT?


[link to this post]
 
I moved from a LLU Be Unlimited connection to an Orange BT sourced connection (Blackburn Exchange) and have noticed a massive difference in sync speeds.

Before I would get a solid 5000k down and 900k up. These are my current stats:

Downstream Upstream
SNR Margin : 2.8 10.2 db
Line Attenuation : 59.0 34.8 db
Data Rate : 4619 291 kbps
POWER : 0.0 12.3 dbm
CRC : 4024 65445

I'm finding that the connection starts out strong and then over a period of days drops upstream from 800k to sub 200k, the downstream goes down somewhat too. I don't remember by SNR ever being this low before - my attenuation was less too off memory. I should point out, I did have a Netgear DG834G (v1) before and now I'm using a TP-Link TD-W8961ND.

Your Down Sync is very good for your attn. Orange, i.e. BTw, default to a Target NM of 3 dB.

Your Up Sync is very low. How long have you been with them? I found my Up Sync was low, 444 kbps, to start with and took over a month to move up to 888 kbps and eventually 1.2 Meg.

Around 3 weeks - I thought enough for the line to settle.

My stats right now are almost exactly as last night:

SNR Margin : 2.1 10.2 db
Line Attenuation : 59.0 34.8 db
Data Rate : 4619 291 kbps
POWER : 0.0 12.3 dbm
CRC : 9073 65445
