Broadband started dropping out recently

Hi folks,

 

I'll cut to the chase. For the past 6 months, broadband has been great but recently (since 21st Oct) it has starting dropping out regularly - 6-7 times a day. Seems like the hub is rebooting itself, perhaps?

 

Anyway, been through the BT troubleshooting guides/desktop help app/line checker tool and followed most threads on here. As far as I am aware, speeds are pretty good and noise levels are fine. Internal wiring is all fine; although the day the trouble started, there was an engineer in the cabinet outside my house - could be unrelated. As I say, was working fine for 6 months (in fact, the event logs show this too) and no changes in usage/wiring etc. that could have caused problems. Hopefully the logs below can help shed light on the issue...

 

Anyone with any ideas why these sudden drop outs have started appearing?

 

Thanks,

Ben.

Re: Broadband started dropping out recently

To reproduce this fault all you need to do is to go to

https://www.bt.com/consumerFaultTracking/secure/faults/reporting.do?pageId=21

entre your phone number and press the continue button.

This results in the hub light going red and the following initial error log

18:09:29, 06 Sep. (32098.880000) PPP LCP Send Termination Request [User request]

BOOT ERRORS do not show the local end seems to stay connected since when the hub is fully connected you are able to refresh the link you were on ifother sessions were open

Re: Broadband started dropping out recently

the hub will perform as you say as the line test disconnects the broadband connection
