Hi all, have a question I hope someone might be able to help out with. We had VDSL installed prior to christmas (moved house to one ~18 years old) and my sync rates seem to be all over the show. I don't know whether or not this is DLM doing it's thing as it seems a bit extreme to me.
Bit of background:
I'm about 160m walking distance to the cabinet (understand cable length could be considerably longer) however my attenuation and sync speed seem to jump all over the place.
When we moved in I cleaned up the internal wiring as best I could by removing all jackpoints except one to the office. Unfortunately I couldn't replace the cables as there's not really enough roof-space to do it myself. Removing all the jack-points bar one brought my speed from 12mb to ~30mb. I seem to get roughly the same speed in the office as I do when connected to the jack-point closest to the ETP (~4m straight cable) so I've left it in the office.
I was using a fritzbox for a couple of weeks, however it went on the 'fritz' and stopped being able to reconnect DSL for hours at a time (it was suspect before we moved so not surprised). During the time we used it and it worked it sat pretty solidly at 30/5 at ~attn of 22db and SNR of 12db, although sometimes it would reconnect at 50ish/10 for a small period of time.
Have since switched to the ISP provided NF4V which seemed to sync either at 15/5 or 28/9 without a change in attn of ~25db or snr of 12db. Unsure why it's sometimes half as none of the other stats seems to change. I'd left it at 28/9 and it was solid for a few days until the resync listed below.
Yesterday ~3:20pm DSL resync'd itself to 52/11 @ attn of 13db and an SNR of 12db and was solid through to this morning at 4:20am where it's resych'd itself at 5/1 with an attn of 6.5db and an SNR of 28db. Unsure as to what's happened here at the attn is lower than i've ever seen, but SNR is crazy high. SS of DMT as below.
Is this DLM in action, trying a bunch of different stuff to test the quality of the line, or a symptom of a super dodgy line?
Any help would be appreciated!
