Broadband dropout and t3 timeouts

Hi,

I have had fibre for about 6 months now and once a week we would get disconnection of the broadband, then after a few mins it would come back on again but this seems to be coming a lot more frequent lately and it seems from the status report I have quite a few t3 time outs. Does anyone know what would cause these and how I can overcome this problem? 

many thanks

Re: Broadband dropout and t3 timeouts

Your up power levels are all too low 0- below the recommended minimum level So they are struggling - hence the T3 timeouts

Will need a tech visit to adjust them - calling in will be quickest - VM can take a day or two to get here

Re: Broadband dropout and t3 timeouts

Hi Stephenkane85, thanks for getting in touch.

 

Sorry to hear about the connection issues you've experienced. Adjusting the power-levels is usually an easy fix for an engineer. 

I can't see that action has been taken for this so far - so I'll get in touch via PM to assist further.
