I was idly wondering what others had done to their own, or friends/family's installations, that resolved problems and increased speeds. I find it interesting to see what benefit there is from a particular 'fix', though of course the remedy is very dependent on the original problem.
Perhaps , though, there isn't an original 'problem', other than desiring a little more throughput, which has been obtained by cat5 cables for telephony, filtered faceplates or crystals, magnets and runes hung from the nearby pole.
For example, from my original setup that led me here in search of a solution, (I had ADSL noise on the voice phone) I got a quite reasonable 15424 down, but after installing a filtered faceplate on the master socket (which entirely cut the ADSL noise I could hear on voice calls) , I eventually achieved around 21000 down and a drop in attenuation from 23 to 21db.
