Router DNS problem

Router DNS problems
Over the last week my router keeps loosing DNS connection so my devices are unable to connect to the internet.

The router connects to broadband shows a solid white light but my devices show no internet connection almost certainly because of the lack of DNS 

tracert finds, the router shows a DNS connection to but times out

The router shows version SG4K10002816t 

Powering off the router for a period resolves the problem but then at some stage DNS is lost again.


This post indicates there is a known problem with this router and version SG4K10002816t.


I suspect the problem has resulted from a version update on my router but I have not been able to find the router logs to see when the router was updated. As a result of this  problem my internet connection is now unreliable. I have tried Automatic DNS setting using Talktalk and Manual settings using Google and both settings exhibit the problem.


I think I will need a replacement Router to solve this problem.

Thank you, hopefully different router will solve the problem.
I lost DNS again this morning on the version SG4K10002816t router and had to reset DNS settings to auto to get internet access back.

Hi alfa1


Apologies for this.


I have ordered a Huawei WIFI hub for testing, please allow 24-48hrs for this to arrive.


Let us know how the connection compares with this router.

Hi @alfa1,


You are correct that this issue is affecting a number of people with the Sagemcom Wi-Fi hub, the staff here will be back tomorrow, so they will hopefully be able to respond within a few days to help further.
