Over a week ago both my phone and broadband went down and I tracked the problem back to the extension wiring punched into the NTE5A face plate coming loose. I have fixed this but my broadband speed was syncing really low. Since last sunday I've been running exclusively from the test socket of the NTE5A so my internal wiring is ruled out.
I usually sync around 37 down, 6 up. Initially it was syncing at 5 down with a massive SNR margin. After 2 days of uptime it resynced at 20, with an snr margin of 15db.
My ISP has sent a replacement router/filter etc and I've been using that since Thursday and a DLM reset was performed on Friday after they apparently saw that it had capped me.
I know the cabinet I'm on (ECI) was full last year and they have put in an extra one about 6 months ago.

The line attenuation is a lot higher on the Fritz!Box from (14.8 to 20db). It's from exactly the same point, not sure which is more accurate.

My concern is that it's syncing just over what my ISP will deem a problem which is 50% of expected sync speed (23250kbps in my case) and they are going to try say this is normal.
Am I expecting too much from my line? Any help appreciated.
Thanks.
