Fibre 65 unacceptably low speeds

[fire2burn]

I have fibre 65 via a dsl-3782 router provided by talktalk. Up until recently I was getting 50Mbps however now the link rate has dropped by more than half to 20000/19999 Kbps. This is a recurrent issue that seems to occur at 6 monthly intervals where the speed just plummets then it requires input from talktalk to sort and return the speed to normal. I have a previous thread on the same issue here: https://community.talktalk.co.uk/t5/Fibre/Download-speed-more-than-halved-on-fibre-65/td-p/3056092

I am currently awaiting for an upgrade to full fibre 500 however as yet I don't have a date as to when this is going to take place as openreach will need to dig up my front garden to install new ducting to facilitate this. In the mean time I'm stuck on a connection that can barely run youtube without constant buffering. Is there anything talktalk can do your end to return the speed back up 50Mbps as was done previously?

Hi fireburn,

I've ordered a replacement router, it should be with you within a couple of working days

Yes please if we could try a new router in the mean time. I've had an email from Openreach that the work to install full fibre won't be taking place until May 9th at the earliest so will have to make do with the existing problematic connection for now.

Hi @fire2burn 

I'm sorry to hear this.

The line tests are clear but I can see that the speed has dropped.

Would you like me to send a new router?
