Line speed has decreased?

Well I'm always having problems with my speed, but this time it seems my line speed has gone down. My usual "accecptable range of speeds" is 0.4-1mbps or more, but these are my current speed tests:

Download speedachieved during the test was - 0.51 Mbps
For your connection, the acceptable range of speeds is 0.1 Mbps-0.5 Mbps.
IP Profile for your line is - 0.56 Mbps

It's saying the accecptable range of speeds for me is max 0.5mbps, when not long ago it was much more and when I do a BT line test it says I should at least be getting 1mbps on my line.

I've done the quiet line test, and got nothing and I don't have a test socket on my master socket so can't do that. There have been no problems before and this all came on suddenly a few weeks back.

Hi,

I would advise contacting the Helpdesk, as they'll need to run a full set of checks.

Before you call though, I would try the following if you haven't already:

- Call the Telephony Helpdesk on 0800 800 154 and have them check the phone line.
- Change the microfilter.
- Check the cabling to make sure there are no loose or broken connections.
- Switch the router off for a couple of minutes.
- Connect an alternate router to see if this helps.
