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.

They go hand-in-hand anyway. Whenever BB discons for whatever reason, it results in a resync which has potential to change IP addy.

Which EE router & WiFi extenders, if any, do you have (read label or post a pix)?

[Geoggy25]

I have the WiFi 7 one and the extenders that come with it

@Geoggy25 Which one there are two the 7 Pro or the 7 Plus? Are you also getting the EE IP/DNS values or have some other DNS Server selected?

@Geoggy25 Little bit off the Chicken/Egg with this one, is it the Wan that is dropping causing the EE Pro to report, possible that the keep connect has an issue, or be aware the EE Pro router has just FW updated with a possible issues but that has only been in the last week or so, not sure what the 1.6Gb/s DNS/IP is/was like for being sticky or not....

You can test at home by doing a www.whatismyipaddress.com record what it is, do a 5 min power down on the hub when back up see what it is like after that for the wan IP.

Ok thanks Jim. I’m away at the minute but home tomorrow afternoon. I’ll do that and report back.

Openreach swapped the ONS when EE was installed and it’s just never been as stable since.

@Geoggy25 Yes you need a new ONT with the upgrade, 1.6Gb/s requires an ONT with the 2.5Gb/s Ethernet NIC port, there is one of those on the EE Pro Hub and now your new ONT.... Has been reported although a while back now the Hub is very picky about the WAN cable, so not sure if that has ever been looked at or changed out....

I only have a FF500 connection and never had any wan / ont connection issues, then again no longer an EE customer but the EE Smart Hub + was rock solid on the connection until EE messed about with FW to that particular Hub i had at the time....

The test will see how sticky the wan IP is with a 5 minute off time, same IP then it's sticky, different IP it is not!

Going to say over the last 18months or so on a FF connection had about 3 wan drops that the Asus Router picked up on, you are never sure if OR/BTW/ and at that time Sky were the issue, so far on vodafone last 6 weeks nothing at all drop wise. 

The current reported stability is all to do with the 2.4Ghz band on the smart channel Auto setting, changing to fixed values off either 1,6,11 sort's it all out, those are the good recommended housekeeping channels.
