Regular drops in speed

Go to solution

For a while now, I've had regular drops in download speed. I usually have speeds of between 8 and 12 Mbps, but it will regularly drop to as low as 100Kbps rendering the broadband completely useless. The homehub will occasionally drop the connection entirely too and more rarely it will drop all wireless devices. To me it seem there's a fault with the Homehub, but I have no way of knowing for sure.

 

ADSL Line StatusConnection InformationLine state: Connected
Connection time: 3 days, 10:55:06
Downstream: 6.493 Mbps

As you can see it's looking grim. Right now the download speed is probably around 200Kbps, I can't use any kind of speed test becasue it's just too slow to respond.

For the past 3 days, I've noticed the download speed has dropped at around this time. Each time the noise margin will drop to below 5dB. Throughout the day I've had no issues with the download speed, only now has it dropped. 

 

I've done a quiet line test with no issues there. 

 

After about 5 mins of typing:

Re: Regular drops in speed

there looks like a problem in that you show interleaved but all your stats and nil fec errors suggest you are actually on 'fast'

 

your curreny connection speed is 6493 and as you are on 21CN i would expect the profile to be correct so possible download speed low.  if you cannot run btspeedtester can you try the beta/lite version as that shoild give download speed.

 

are you connected to master or test socket?

Re: Regular drops in speed

Hi Welcome to the forums

Here are some help pages done by CL Keith http://www.btinternet.com/~cbeddoe/speed/Speed.html

 

Can you also post the full results fromBT Speedtest speedtester.bt.com

Have you tried connecting to the test socket at the rear of the master socket   Test Socket.jpg

Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal


This is a customer to customer self help forum the only BT presence here are the forum moderators

Re: Regular drops in speed

I have it connected to the test socket, through the supplied ADSL filter.

 

As for speed tester, I can't even load the page. I don't think it's going to be of much use right now.

As for the downstream it's normally around 9Mbps, only recently has it dropped to 6.4. 

 

I'll see if I can get a result from speed tester beta.

Yeah the line is silent, no issues there.

Reading through that site right now. I forgot about resyncing it, so I'll try that.

Resynced it. It's still slow, but at least I can load web pages now. I'm guessing it'll pick itself up again eventually.

Noise margin is back to normal again now. I've also noticed that the latency type is now set to fast.

I've had no further issues since resyncing the connection. I'll remember that for next time.

Re: Regular drops in speed

i have the same issue and tried all the options and had an engineer test the line in the house and ok up to 10Mbps at time of test.  The speed last night was worse than dial up!

 

Below is the latest details of the hub test and my only conclusion issue lies at connection at the exchange?
