i’ve had two years of b’band issues (slow, frequent drops etc) and constantly blamed the supplier.
now with plus net, they did a load of testing and told me that the fault was with my wiring. yeah right i thought… so a bit of googling and read about ring wires.
long and short is that when the electricians rewired my house they put the master socket directly under the fuse box. so by bodging an old socket rather than putting on a new one and the placement caused my probs. so ring wires disconnected and my b’band doubled within 24hrs.
i have a comprehensive guide to adsl issues, sockets and wiring that a seller on ebay mailed me last week. it makes interesting reading and no he was not pushing me to buy stuff off him. if you want email me and i will fire it over, it may help.
