Router Restarts Regularly

[maccy20]

Hi

I am hoping someone on here can help as I’ve been on the phone to EE support three or four times a day for three weeks. 
I have the Smart Hub 6 router and it constantly restarts throughout the day. Between 6am and 11pm it happens around 8 or 9 times. 
Things I have tried - new router. New power cable to router. Three different sockets (wall and extensions from other parts of the house). I have also even changed the plug to the Open Reach box on the wall. 
Every time I speak with EE they run a diagnostic and everything is fine. I then get assigned an engineer who runs a test on the line to the house. And after seeing that all is ok. They close the case. This has happened three times now. 
I am at a loss as to what to do next. Can anyone advise? TIA

@maccy20 I no longer have an EE Router to check but going to say eth4 and 0 is two port's connected to devices you have, my example port 4 would have been on a Tp-Link device and the eth0 i think will be your wan port connection, anyway does not matter, power down reset the ports will go OFF then back to ON....

Will take a look at your pictures, you are either getting reset externally, or your PSU or power supply is blipping enough to cause the Router to drop out and reset itself! 

One major is having the PSU on a multi block power strip connection, have seen real cheap ones drop the connection as the strip inside is made of bad material, so if possible get the PSU Direct on a mains power socket at least for a test!

I never had any issues with power to the Router so may have just been lucky but the router was not pushed hard as behind it was a full blown Asus Ai Mesh router network, so the EE Router was never really that stressed connection load wise!

Thanks again for a detailed response. I assumed it was just saying it was the two ports that are connected. Yes the red one connected to the open reach box and another for lights. Which I have now also taken out to test. 

i have tried the plug in two different wall sockets. Both have had other things in them before with a clock. And that has never reset. So now there is no drop out when they are plugged in

@maccy20 Do me a favour, capture your log file as a start just as you see the sample i put up, the mac's need to be obscured so the ?? was my way off doing it all for you!!!!

What i do not like is your light off, that's a sure sign the power is gone, so you've done the sockets good test, clock in next to that power dip assume you clock goes to the flashing reset mode, and next, the back of the EE Router and the barrel connector make sur it is pushed in firmly, don't be excessive with it but it is a very small barrel connection for that EE Router model....

You have very similar symptoms to a bad PSU but not Exactly the same so i am not going to go that route as yet as you have said multiple PSU units and now on your second EE Router! 

Please do check the push back off the Router though for the connector!

It definitely sounds like a power related issue so it could be the PSU, a hardware issue (internally)  or possibly even a thermal cut out, does your Hub have clear ventilation? nothing blocking or it's not tucked in behind anything etc? If there's no event logs apart from after the "bootup" stage then the router isn't saving logs before the crash, or the logs that are accessible on the hub are not verbose enough. I'd push for EE CS for a replacement hub.

Sorry I don’t see what you have uploaded. Do you want to see the information for the router or the debug log?

[maccy20]

This is the second one they have sent and the third power cable

Ah, then unless it's a faulty socket where you're connecting it. I assume you're plugging it near where the ONT is? can you run an extension cable for a day from another socket just to confirm that is NOTthe case.. if it's not the case then you've just been reallllyyy unlucky.

[maccy20]

I have tried two different wall sockets in different rooms and two extension cables from two other sockets. I’ve done this with the router and the open reach wall box

[Jacob_]

Seems like you're really unlucky then, see if you can get a new one sent from EE CS. I noted you said it's your second replacement, how much later was it you continued to have the same reboot symptoms on the "new" router they sent you?

[maccy20]

Immediately. Within the first two hours it was restarting. 

is there anyway that is a device that is connected to the router? And could I find out which? 

CS are saying none pre flagging up as any issue
