Recently switched to vodafone 1gb fibre and I frequently get network drops.

When checking the event viewer, I see multiple entries of '..........timed out after none of the configured DNS servers responded'.

I tried updating the realtek ethernet drivers, but I am still experiencing dropouts.

I don't have DNS servers specified on my Win10 machine and it is connected directly via cable to the router. DNS settings should be automatically retrieved from the vodafone powerhub.

I don't know how to get to the bottom of this issue and grateful for any advice.

I mean, at least try it? Put Cloudflare (1.1.1.1, 1.0.0.1) or Google (8.8.8.8, 8.8.4.4) DNS servers in and see if it resolves the problem. It'll help narrow down where the issue is.
 
I would guess it's Vodafone DNS servers being, well, typical ISP DNS servers. Try changing the upstream DNS to Cloudflare/Quad 9 or similar, or hand out direct via DHCP.
 
Thanks.

I have changed DNS settings on the vodafone powerhub: primary: 1.1.1.1, secondary: 8.8.8.8

I hope that fixes things. I will report back after sufficient time.
 
Haven't noticed any DNS errors since I updated them. However, the event viewer reports a lot of '.....did not register with DCOM within the required timeout.' - this might be nothing as I have not monitored that before and could have always been there.

Nothing to worry about.

You would be wise to change the DNS servers specified within DHCP on your router to prevent the rest of your network from experiencing those same DNS outages as you were previously.

And, if you're a bit privacy conscious, consider not using Google DNS and instead use DNS servers that prioritise security and privacy.
