Im currently with EurISP (who provide services for Fast4) so lve been through pretty much the same problems as Fast4 sadly however the saga continues, lm currently having a battle with Sync loss..
in fact within the last nearly two hours my connection has lost sync according to eurisp abour once every 2 mins or less this started happening at 8.50am Monday
it also came to my attention that my old modem wasnt reading the stats correctly when concerning noise margins which have gone as low as 2 (lm told thats bad) and go as high as 12 now lm by no means new to DSL but theres still allot for me to learn about the technology.
l will also note a BT engineer came round on Friday the 7th after spending 15mins rewiring it so l couldnt connect to the internet (basically he fitted it so l had 2 filters on my line, you see the extension to my room thyat goes the the modem had its own filter) and connecting his tools saying everything was fine.. what shocked me the most is the fact he wondered why we had a surge protector fitted to the phone line.. well obviously he hasnt had a computer blown up by lightning strong enough to take out the phone line for a week and a computer.
in short lm very peeved off at BT
ld also like to note that in the duration of tying this message l have lost sync 7 times thats basically once a minute, imagine that lasting 2 hours [and counting] (my profile is defiantly going to be capped at 2Meg)
