DNS failure every time EE change IP address

[Geoggy25]

 

Hi

Ive been with Openreach FTTP providers since I moved into a new build in 2019. 
Had no issues until so contracted with EE for their top 1.6gb package.

Every time EE change my IP it causes my broadband to fall over.

I have a Keep Connect plug which reboots the system when it detects this so that if I am away from home I can still access my home network.

See the logs attached. The last time so raised this with EE they sent an Openreach engineer out to investigate. He said he could see at their end that our port was damaged so he moved my service to a different port.

This time all EE did was open a complaint, do nothing, then close the complaint.

Ive just had yet another reboot and I’m getting sick of it. Any advice would be most welcome.

@Geoggy25 Different now, when you say ONT has gone Red light on either LOS or PON then sure looks like that is going to be the issue, going to have a close look at your log file to try working out the scenario, think your ONT will have an Off/On push power button to use that as a test, that will let you know if off for 5 mins if you wan IP gets changed and what your adapter also reports when it see's that happen.

How the timing looks re-organised
