Unstable connection on full fiber

Jt2691 — Wed, 30 Jul 2025 17:14:01 GMT

Hello,

I am having an issue where my connection is unstable. If I run a speed test it shows my connection is perfect however every so often there us a "blip" which disconnects the VPN for work and interrupts voice/video calls. I have spoken to customer care repeatedly and I just keep getting asked about Wifi etc whereas I am on a cabled connection. I keep getting told my connection is fine and it's not TalkTalks problem. To prove a point a have been pinging the router and Google server all day and I can show that the connection to my router has no issues however pings to Google fail which coincides with my other issues:

I am one step away from changing providers however I thought I would ask here first.

Any help appreciated, thanks.

A ping general failure can indicate a problem with your network adapter or Ethernet cable.

Have you tried disconnecting & reconnecting the cable in case it is not seated properly at either end? Also, try replacing the cable. Are there any kinks or damage to the existing cable? Watch out for plastic covers over the RJ45 plugs; these can sometimes stop the cable from connecting fully into the socket.

Do you have any duplicate IP addresses on your network? How does this adapter get its IP address allocated, via DHCP or statically configured on the network adapter itself?

Is the Ethernet adapter running an up-to-date driver? Assuming no driver problem, you could try these commands from an elevated command prompt:-

netsh winsock reset
netsh int ip reset
ipconfig /flushdns

If those commands didn't help, sometimes uninstalling the network adapter and rebooting (which will automatically reinstall the adapter) helps. To uninstall, go to Device Manager, right-click on the adapter, and select "Uninstall."
