I seem to be limited to 4MB/s... Did I annoy someb...

Question

I've been having problems with my broadband connection/speed over the past few weeks. On the 27th I put in a call and reported a fault. The guy I spoke to said "my issue would be resolved within 4 days" and it wasn't... So I called again last night. Now, maybe I should have waited 4 WORKING days but since the help line is open 24/7 I assumed that BT would be working 24/7 to fix this. Silly of me? Maybe. But an honest mistake on my part!! I use the Internet 24/7 so I notice the second I have a problem and I don't like to be messed around any more than the next man. Anyway, I called up last night and was told there was no fault... The guy told me to replace the filters as a faulty filter could cause my broadband to drop out and slow down. I only replaced them a couple of months ago and I don't have spares so he said he would send some out, free of charge, and I would have them within 2 working days.  I highly doubt that the filter is the problem but anyway, I continued to test my line and when I went to sleep at around 11pm my speed was around 3.5MB/s. I just woke up (3am) and have been testing for an hour...normaly at this time I'm achieving speeds in excess of 6MB/s but I've not been able to get anything over 4MB/s and I'm getting very consistent results of around 3.9MB/s...  I'm no expert but it does seem like I have been limited to 4MB/s. Here is a screen shot of my speed test results presented in a graph:

you can see a very suspicious looking flat line there which is very unusual and only seems to have started since I put in the call last night. You can also see my speed dropping out to less than 1MB/s so you know I'm really not making this issue up!!! I pay the full price for the full package with unlimited downloads etc and I use the Internet A LOT. I suffer with mental health issues and I'm at home all the time on the Internet so having my service disrupted like this has had a BIG effect on me and maybe I am become obsessed?.. But I know there is a problem!!! I cant play online games because I keep getting disconnected. This is a problem that has only existed for the last few weeks..i never had a problem before and I've been gaming at this address for over 2 years. I UNDERSTAND THAT MY SPEED WILL DROP DURING PEAK TIMES!!!!!!!!!!!!! But that has never stopped me from gaming before and on the 27th when I put in the first call I couldn't even stream a 240p youtube video... It was that bad.
I have ordered new filters form Amazon (don't wanna wait 2 days) so I can confirm that isn't the problem when I call them back but I just don't see what else I can do about this and having my speed limited seems extremely unfair! I wasn't rude at all in anyway. I just asked him what was going on. Maybe I am being totally paranoid??? But this is really driving me insane!! I just want to get back to some kind of normality and i have a nasty feeling that BT wont do anything to help. i cant "live with it" i would rather cancel my contract than live with this.
Any advise would be greatly appreciated!!

Answer 1

Oh I see that would explain my problems this afternoon then.
it maybe worth adding that although my connection normally does slow down in the evenings, its not every day that it tends to cut out and drop down to silly speeds (less than 500KB/s). I had no problems on Friday or Saturday night and was recording speeds of over 4MB/s even at peak times. It was Sunday afternoon that the problem seemed to start again, dropping to less than 1MB/s and I was getting a 250ms Ping with a -166% packet loss. This really makes no sense to me... How can it lose more packets than it started with? Or am I reading the results wrong? Anyway, it wasn't as bad as the 27th but still unusable really.  And your right I am very close to the exchange. I could probably throw a stone at it while standing in my garden.
Speed test (17:05pm):
 Download speedachieved during the test was - 2815 Kbps
 For your connection, the acceptable range of speeds is 600-7150 Kbps.
 Additional Information:
 Your DSL Connection Rate :7616 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 6500 Kbps
This drop in speed is understandable at this time and today my Ping is great at 55ms. Was around 3pm yesterday that I first got disconnected from my gaming session. And I did a speed test which recorded a bandwidth of around 2MB/s with a Ping around 100-150ms. I'll test again at 7pm and post the results.
Speed test (19:00pm)
Download speedachieved during the test was - 4010 Kbps
 For your connection, the acceptable range of speeds is 600-7150 Kbps.

So there seems to be no problem at all this evening. Ping is great. Speed is fine. Not really any issues today... You could easily believe that there is no issue at all... And that's exactly why it makes no sense to me. 1 day its fine and the next mi getting cut off, speeds drop way below what they should be and my ping is all over the place. Am I to accept this as normal service now? I'm really not happy about it. There have been times that the speed has dropped way below "the acceptable range of speeds" and so I'm finding it hard to believe there isn't a problem... Only thing left to do now is get the new filters and wait to see if they resolve the issue.

*Facepalm* FML!!!
Ping Flood??
I did receive threats just recently that I would be hacked... Could this possibly be the issue?
Had problems from around 8pm -10:30pm. Speed was ranging wildly from 0.7MB/s to 4.0MB/s during this time and the ping was also all over the place. Take a look at this:
http://gyazo.com/ca21b2cb6fa9c5172a7f308e9d47af9e
Speed and ping seemed to very quickly return to normal (55ms 5-6MB/s) around 10:30pm
 and had no problems up until 2:20am when I lost Internet connection again. Seemed exactly the same as earlier in that I couldn't load a webpage but the broadband light on my home hub was glowing blue.that only lasted for a few minutes and now everything is fine again.
