Constantly intermittent wifi

[fordxman5]

Hi, I have had an engineer come by and change some wires but I still have the problem of intermittent wifi; the wifi slows down, the router reboots and at first displays red wifi lights, then 3 green lights. It then starts after a couple of minutes.

This is on all devices, over wifi, and happens approximately 10-15 times a day at this point. 

A principle engineer will be visiting, but this required a lot of talking as everyone on the call centres claims there is no fault. 

Here are my logs:

help please

[Sasha_W]

I will pop you over a PM so we can have a closer look at your account, 

Please look out for the purple envelope at the top right hand corner of you page as this will take you to PM's. 

Thanks

Told me the same thing as the phone lines - can't see an issue with my account, very dissapointed

BQM is full of red I don't know what else is needed

[fordxman5]

I tested the router in modem mode connected to a laptop; when the internet connection cuts out the white light on the bottom flashes. With the same old T3 error 

Maybe this can infer anything? 

Thanks

Update: another engineer is being sent this time to check all of the cabinet 

Incase of this failing it's cable repull time 

[fordxman5]

Update 2: 

Corroded cables found in manhole; were replaced issue is still present.

Repull is booked I believe hopefully this fixes it because these are 20+ year old NTL Telewest cables.

[Zak_M]

Thank you so much for the update @fordxman5 

Please do let us know how the re-pull goes. 

Kind regards,

Zak_M

Update

Router change, repull didn't fix problem  

T3 time out still happening
