Line speed slowing down gradually over the last week.

Is it possible to get the line speed reset. Nothing in my home has changed, and this is starting to get old as we have do this dance every year.

I usually have a line speed of 21xxxKbps.  However I noticed that my board band was slower than usual about two weeks ago.  So I logged into to my router and checked the line speed. It was at exactly 19000kbps.  

Today I logged in again and checked the line speed. This time it had fallen to exactly 18000kbps.  

These exact numbers look too perfect for the line to have magically decided this was the best speed it could obtain.  The upload speed is unchanged at 3210kbps (since the last BT callout). 

I have this issue every year with BT, last year over a three week period the download speed dropped to 4000Kbps. The last time the BT Engineer showed up, I did state that I was expecting the upload speed to be slightly greater than 3500Kbps. However he said that's not what BT offer, and there was clearly no point arguing the point with him over 200Kbps.

Re: Line speed slowing down gradually over the last week.

If your connection speed is dropping then your router is dropping connection suggesting there is a problem with your connection.  your abbreviated stats do not show internet connection time (not system time) but I would expect that to be very short

can you enter you phone number and post results  remember delete number but leave exchange and cab

can you check line for noise   dial 17070 option 2  should be silent and preferably with corded phone from test socket

Hi,

Thank you, for your prompt reply, and the appropriate modification to my post.

The uptime right now is 12 hours, as I rebooted the modem last night.  I didn’t check the uptime prior to rebooting. 

The quiet line test, has a slight hiss on it. Nothing I would be concerned about as that could just be the handsets amplifier circuitry.

Re: Line speed slowing down gradually over the last week.

any noise on quiet line test is a problem for broadband.  I would check from test socket and see if noise/hiss still there and if so report phone fault to 150 (a dull hum is normal for cordless phone)

Thanks, 

I’ll give them a call. You can delete this thread if you like.  I’m sure they will sort it out.

Re: Line speed slowing down gradually over the last week.

As you are well within the range shown by the checker I doubt they'll do anything.
