Kodi causing internet to crash

Hi,
Since my box provider has thrown his hands up on any further support reaching out on the forum…. As soon as I turn my Ubuntu box on and Kodi loads, while its scanning for new content it causes my internet to crash, to the extent that a few days ago it even caused my router to reset to factory settings.
My provider had a few months ago said that its because of Man in the Middle attacks and had reinstallted the system but since last couple of days its happening again massively and I can’t seem to find a way to fix it.
I’ve tried disabling the youtube add-on and a few other addons but it still doesn’t seem to be working.
Am not sure if the crashlogs are also getting uploaded especially because the whole system was setup by the provider and he has given me limited accessibility but I can try and work it with some guidance.
Please advise.
Thanks
