Very slow download speed though modem line rate normal

Go to solution

Hi

 

I recently noticed (today, 31st December) that our download speed had dropped very low, to approx 0.5Mbps. The upload speed is normal, approx 1Mbps. The modem line rate is however normal (8Mbps dowm, 1Mbps up). I have checked the download speed using http://speedtest.btwholesale.com/. I am at postcode SK237FN and have had consistently reliable download speeds for several years, 5-7Mbps.

 

Please help!

 

I already tried rebooting my router but this has not improved matters.

 

Thanks...

 

Test Result

Best Effort Test: -provides background information.

 Download  Speed
 0.59 Mbps
  
0 Mbps7.15 Mbps
Max Achievable Speed

 Download speedachieved during the test was - 0.59 Mbps
 For your connection, the acceptable range of speeds is 2 Mbps-7.15 Mbps.
 IP Profile for your line is - 7.2 Mbps

Hi

 

Thanks for your quick reply.

 

I don't use a BT "home hub"; I use a Billion router, ADSL status below.

The speedtest was performed using a wired connection.

are you connected to test socket?  if not can you connect to test socket with new filter and repost the router stats please

 

with your attenuation I would expect a connection speed about 13mb

Hi. There were no issues reported on those sites for my exchange. Thanks for the useful links though...
My connection speed is now back to normal (I have not changed anything).
Thanks again.

I am not connected to a test socket and I'm not certain what you mean by that. I'd certainly be interested in 13Mbps if that were possible...
Thanks,mike

Thanks. Don't think my master socket is so modern. Can one get a new master socket fitted by bt?
