On ADSLx, on a fairly new master > 8 metre wire to gable junction > new drop wire to pole, I bought an ADSL Nation XTE-5 and one of their better quality ADSL cables hoping to improve my ~5Mbps connection to O2 LLU.
At the time I was using a dangly filter, one of 8 or 10 from many router supplies, and one of the associated DSL cables. I was able to test exhaustively as on O2 LLU DLM was not enabled after the initial few days.
By exhaustively I mean methodically changing the filters with the same DSL cable, then with the top one changing the DSL cable.
I then compared this result with the XTE-5 plus posh DSL cable, and XTE-5 with all DSL cables.
I did this twice on different days.
The XTE-5 and posh cable have been in their received packaging in a drawer ever since. It wasn't worth the hassle and possible cost of returning them for a refund. I used the best cable/dangly combo until I got the VDSL2 interstitial filter for FTTC and IIRC used the HG612 DSL cable. I consistently got 170-200kbps better on most combos. A few were below the ADSL Nation variants.
In particular the posh DSL cable was a liability.
Very near by is the DECT phone base station. the power for that is from a 4-way socket on something like a 10m lead from the mains socket, and the modem is plugged into another 4-way fed from the first. Printer and shredder permanently lugged into the first, router into the second. Local laptop occasionally also into the second.
(Hmmm - what else is plugged in? IIRC I have two spare sockets, but that gives three).
Kindness isn't going to cure the world of all its awfulness but it's a good place to begin. Daisy Ridley.
