I've been having some problem with my ADSL2 broadband for about a month now, I've raised the issue with my ISP (Plusnet) but they say because it meets minimum agreed speed of 1MB they won't raise a fault for it.
What i've tried
New modem, new microfilter, new cable, plugged into test socket of master socket already, several reboots, quiet line test (all quiet).
So the problem started about a month ago, I have 3 ADSL lines coming into the house (I work from home so need the redundancy, and with 3 kids, more bandwidth :p), all 3 were syncing at abouyt 2.5MB steadily each time, never an issue. However the 1 line in question, for no reason a month or so ago decided it would never sync above 1.4MB.
Router stats are showing an "Attainable rate of about 2.7MB", all 3 modems I have are exact same brand/model and both the other lines sync near that "Attainable rate" and so did this line before the fault.
Link Power State
Line Coding (Trellis)
SNR Margin (dB)
Output Power (dBm)
Attainable Rate (Kbps)
MSGc (# of bytes in overhead channel message)
B (# of bytes in Mux Data Frame)
M (# of Mux Data Frames in FEC Data Frame)
T (Mux Data Frames over sync bytes)
R (# of check bytes in FEC Data Frame)
S (ratio of FEC over PMD Data Frame length)
L (# of bits in PMD Data Frame)
D (interleaver depth)
INP (DMT symbol)
Super Frame Errors
RS Correctable Errors
RS Uncorrectable Errors
I'm at a loss as to what to try, the ISP refuses to raise a fault for it because my minimum agreed service level is 1MB
WBC ADSL 2+
Up to 1.5
1 to 3.5
Does anyone have any suggestions on how I'd proceed to get his rectified? 1MB may not sound like a lot to a lot of people, but it's a 40%+ drop in speeds for me 🙂
as you are now a plusnet customer and not BT Retail you need to post on the plusnet forum for assistance
