Have this problem over a month now

Question

Afternoon everyone,
Where should I start..
About a month ago my hub started resetting itself whenever I used internet, i spoke to numerous amount of people over at the call centre and about 2 weeks after calling them nearly every day they sent openreach engineer over to my house to check whats going on. He did what he had to do inside my house and outside my house, then he did some tests which all said "passed", but hey after the visit i went straight on my computer and checked the speeds which were at about 1mb at the time which still are not good enough considering i had 6-8mb about 3 months ago, anyway back on the subject i contacted bt yet again and they said the line needs to be running few days for the connection to stabilise. A week of waiting and still nonthing speeds the same and my hub was still resetting itself but not as often as it used to. After a week I decided im not going to bother with those useless people in the call centre so I emailed bt and started to explain my problem all over again, first they sent an engineer to my exchange to see whats going on there, still nothing improved after that. They then decided that they should send an engineer again which came to my house yesterday and replaced the master socket and also did other things which i didnt see. He then like the first engineer did some tests and he said that the speed hes getting from the master socket is 9.7mb i was all excited that i finally got back speeds i used to have about 3months ago but hey, went on the computer straight away after the visit and the speeds were at 500kb/s. I had an idea today that maybe i should bring my computer downstairs with the hub and connect it to the master socket but still nothing.. same speeds and the hub is still resetting from time to time, if i counted correctly the hub resetted 7 times today and 4/7 of them resets the hub didnt connect to the broadband for about an hour and on one reset it didnt connect for 4 hours the rest connected in about a minute. This is really going beyond a joke now, really unuhappy with the whole situation which i repeat had for over a MONTH now. Im thinking of changing to another ISP and as bt said if i change from bt to any isp the problem will still remain id prefer to talk to normal people and not the callcentre which as a matter of fact everybody knows is useless and you can barely understand what they are trying to say due to obvious reasons.
