Hello,

Ok. Would you like us to send a replacement router for testing purposes to see how this compares? We would also send a router returns bag so that one of the routers can be returned.

Thanks

Both. I can still get to router when the drop happens.

Hi

all tests are clear and I cannot see any retrains showing (drops).  Are you seeing internet drops from wired devices or Wifi ?

Thanks  

Karl.

This log message is not the cause of your problem.

It is written to the system log when a device on your network tries to reach a website that cannot be resolved to an IP address in the DNS server within the router or higher up the DNS hierarchy. However, there is a bug associated with this message that I have reported to TalkTalk. The severity assigned to these messages is "Error" when it should be "Informational". This means that it cannot be filtered out without filtering out far more important messages. To stop these messages is not easy unless you can determine which of your devices is generating these DNS requests and the website they are trying to visit.

I have asked one of TalkTalk's support to pick your thread up and investigate the instability of your G.Fast connection for you.

They aim to respond within 48 hours (Monday - Friday) excluding Bank Holidays, but if more urgent you can always try the Service Centre on 0345 172 0088. The posts are responded to in time/date order, oldest first. Please try to avoid posting on here until TalkTalk has responded to you, otherwise, this will just put you further down the queue.
