Funnily enough my G.INP seemed to come back on the 15 August!
Now it's just gone back to the suspiciously capped 34999 (SNR currently 7.8). I dd get up to 37.5-38.0 ish many months ago before my silly idea of tryin a HH5a internal modem!
I wonder if BT did some G.INP change en-masse... strange co-incidence, though admittedly mine stopped when I did infinity recontract (and hence line reset it seems)
Wish the 35k cap would do one... been on a HG612 for many months now. (and the line is rock stable.. for weeks, months on end until BT force a resync as for profile reset, G.INP activation)
