Very very slow broadband , someone please help

Question

Hi have come here as a last resort , i have been a bt internet/broadband user for over 10 years have had broadband for a long time , we often in our house have me playing games online on the pc , the kids have the xbox 360 and the mrs will have the ipad all hooked up at the same time with no problems ,
then friday the broadband dropped and we had a orange flashing light ,
it came back on about 5 mins later and ever since it is very very slow , i have tryed resteing and rebooting the router , it connects to the internet just fine but everything is running ar a snails pace , tryed calling them which is a nightmare trying to explaine to a call center guy , they told me to hang up for a line test and they would call me back and havnt bothered
i have done the line test online it it comes back as ok , we have noticed some nose on the phone line from today
can anyone please give me some advice?

Answer 1

have phoned them 4 times now (2 times on 151) and they ensure me they have tested the line and i have no fault , they set up remote asstent and the guy did a soft restart of my hub which seemed to work , he then tryed to get me a better d/l speed but it whet back to a poor one again , so he again did a soft restart and i now get this:

the downstream and upstream numbers are both better but it has made no differnace, every page i go to takes ages to load (if they load at all) and the ipad wont load at all , this is now getting silly i have wasted around 6 hrs of my time tonight trying to fix this and now just feel like canceling and ordering from eleswhere as i know the messing i will have to go through in the morning to explaine this from the start to a new call center worker all over again
i was led to belive that bt staff would help me if i posted here hence why i did so but even this is looking like a total waste of my time , (no dissrepect to you imjolly for your help)
