Wifi Connection issues for all devices on BT infin...

Question

Hi All,
I recently did a home move and moved my BT infinity from previous address (which worked fine and I had 2 drop outs both 2 minutes long over 3 months) but I have been "using" BT Infinity since Saturday morning and the issues will not stop.
I connected laptops, iphones and consoles to the Wifi and at first i should have been getting 30MB but speed checkers came back with 20mb. Later on that day the connection dropped to less than 2mb on the playstation 3 and then around 5mb on iphones, i even sat right next to wireless router and was getting 15mb, half of what i should be getting.
I enabled port forwarding for the playstation 3 which made no difference, i changed the channel from 1 to 11 and this made no difference, i then called BT helpline (who ran a line test and no issues were found) and connected my laptop via Ethernet cable, she remote assisted me and reset all of my router settings then ran a speed test, it came back 30mb??? then she asked i disconnect cable and try same test with wireless this came back at 33mb, so they said there was no issue.
The second they got off the phone i did a speed check and it was showing half.(around 15mb)
over the whole weekend connection has been dropping out or dropping so low that it really feels like im wasting money.
I have not even dared to set up the BT Vision as the TV will just not be watchable.
I am completely stuck on what to do and have really lost faith in BT, how can the connection jump around that much, each time i run a speed test i get different results, several times during the day the wifi just stops, have turned off router 3 times total which made no difference.
is anyone else getting these sorts of issues? I thought AOL was bad but i went from no issues with a max 1.5mb speed to endless issues with a sporadic connection that goes from half a meg to 22meg (only ever got 30meg result while on the phone to BT which is suspicious)
I know it could be teething issues but at my old address it worked straight away and as i said above was fine in terms of uptime.
Any help would be great, would also love some steps on obtaining info the send to BT to prove there is an issue.
Hope this does not sound like an angry rant but i wasted my whole weekend trying to sort this out (during best heatwave in uk for sometime :-( )
Many thanks
