My connection kept dropping too last week and VM came round and replaced my two month old Modem saying that there was a lot of noise on the line too from outside so the engineer fitted a attenuator and everything was back to wonderful again...until tonight really slow speeds again but no disconnections.....YET!!!
I live in East London too...Sadly Sephiroth that link for East London gave me this from Cable Forum,"Sorry - no matches. Please try some different terms. "

(( Whats happening in East London OMG what are they doing to us...arrggghhhhh
