My bandwidth rapidly decreases over say, 2-3 hours from 7.5mb to around 3mb.
I have determined that it is not the fault of my router as to reset the bandwidth all i need to do is unplug the phone line from the wall and immediately replace it.
It is also nothing to do with the adsl filter as i have tried 6 of them and the problem still persists.

There is no problem with the phone line - everything sounds very clear.
The line has been tested several times and everything seems to be fine :confused:

I am going to have to call BT tomorrow....AGAIN :mad: .... and I could really do with possible reason as to why this may be happening before i speak to those idiots ;)

Cheers

===============================
I desperately need to get away from BT!
Last night i was working on a website and was trying to upload stuff and this was my connection:

Took me half an hour to upload 1mb :(

Traceroutes looked pretty identical. Only made 1 hop each time and took 1ms

Unplugged and reconnected line and it went from 3.5 to 5.9

I read somewhere that the Signal to Noise Ratio should be at least 10 dB to get adsl - ideally above 12dB to get traditional fixed adsl.
Anything less than this will see frequent disconnections and other problems.

Is this correct? I have 6.5 :/

Wish id looked at this info before id reset it. I'll have a look later.

Just had a look at my bosses Link information over TeamViewer ....

Line Attenuation & SN Margin are quite a bit different to mine and his bandwidth never drops
