I currently have an 80/20 product with Plusnet, and am currently synced at 46/12. The estimates for my line were somewhere between 34-47 down and 7-11 up. I went for 80/20 instead of 40/10 because when I signed up a month and a half ago, Plusnet only offered unlimited usage on their 80/20 product. Plusnet are now offering 40/20 with unlimited usage for £5p/m cheaper than what I'm currently paying.
At present, my line is is synced at 46Mbps down, with interleaving enabled. Interleaving is set at 909, INP is set at 3, and delay is set 8. Max attainable is 49.6Mbps
It is synced at 12Mbps up, with no DLM intervention whatsoever, max attainable is 12Mbps.
I use the internet mostly for browsing/email, downloading on usenet (mostly when I'm not in, set up via RSS), streaming to and from the house, and PS4 gaming (in order of most often).
My question is: Would I be better off reducing my speeds to 40Mbps and potentially having interleaving disabled (so better pings etc), or am I better off keeping the higher sync speeds for my usage? I'm happy to pay the extra £5pm if I keep a better level of performance (plus I got the introductory £9.99 for 6 months on my current deal anyway, so total difference over contract is £30)
I realise no one can say for certain whether reducing my speeds to 40Mbps will take away interleaving. I've asked Plusnet, and they've said that whilst chaining to the 40/20 product will not reset DLM, it will re-enter me into the initial training period, which will make DLM more active again.
P.S I'm planning to wait a month or so anyway to see if DLM clears up my current connection, as my connection was messed with a fair bit in the first few days.
