This is actually interesting with changing modem. Last Saturday i switch my old unlocked eci modem for DrayTek vigor2760 as vigor got better specs than eci I though will be a small step forward. However Sunday morning checked stats booth (downstream and upstream) on interleave where last three months I was on fastpatch constantly, line approx 230 mts from cabinet (eci). I didn't have burst of errors, nothing, just swapped modem. Most strange for me thing is that, booth draytek and bt eci modem are with lantiq chipset, where in past I switched modems with different chipsets and never loose fastpatch. Does something changed with eci cabinet?
