Disconnect Every 5 Days at Same Time
Thanks for your post @Nemo154
I'm really sorry to see you're having intermittent issues with your connection.
Do you have anything that comes on in your property like a boiler at the about the time your connection drops?
Also I've arranged for the stability profile of your fibre service at our suppliers end to be increased from the speed profile to a more stable one, which will influence the automated dynamic line management (DLM) software at the cabinet (the green box in the road) to prioritise stability over speed, so it doesn't try to push too much speed down your line it may not be able to handle, because you've said that the problem only begun after moving to fibre extra.
This change should start to take effect within 24-48 hours but as all the change is doing is influencing DLM, it may take around 7 to 14 days for you to hopefully see an improvement.
Let us know how it goes.
No problem @Nemo154
Assuming you've checked your side, there isn't really anything else we can do bar arrange an Openreach engineer visit to investigate further, but I can see you've mentioned on a previous post you don't reckon this is a line problem.
There wouldn't be anything our end that'd cause your connection to drop in this way across multiple routers.
Let us know how it goes though.
Hi @Nemo154 thanks for getting back to me.
I'm really sorry to see you're still having connection issues.
Having tested your line today, I don't think there's anything we or a provider can reset to fix this.
Personally, I'd recommend we arrange an Openreach broadband engineer to investigate further.
When you upgraded your fibre service to fibre extra, no physical changes are made, but more speed is pushed down your line so if there's a physical problem somewhere then it's going to be more noticeable on a higher speed package as the connection will basically be falling over itself.
If you're happy for us to arrange an engineer visit, let me know and I'll raise a ticket on your account you can reply to, alternatively you can raise a fault at faults.plus.net. Either way though let me know. 
Thanks for getting back to me @Nemo154
I don't want to go against the advice an engineer's given you, but the fault was raised as a phone line problem not broadband, so it's possible the engineer may not have trained to look at broadband in-depth.
Also there's nothing our side that can make your router drop your connection in this way.
Can you reply to the support ticket I've logged on your account Here with when you'll be available for an engineer visit?
If you can post back when you've responded, I'll make sure we book the engineer as soon as we can.
There may be nothing an engineer can do due to the frequency of the drops, as our suppliers generally deem an intermittent connection to be 3 drops within 24 hours or 6 drops within 72 hours, however I think it's worth us arranging a broadband engineer to check things out, based on the fact the issues started when you upgraded your fibre service.
Finally if you log into your router settings, do the logs give anything away? Feel free to post a copy here.
