For the last two weeks my Internet has become practically unusable.

 My deco app fails to navigate properly, failing to save settings on many tasks, my messages say I have a software update which disappears the messages also say I have had an intrusion attack. Although when I good to my security portal there are no incidents reported. The app won't successfully reboot either. The app is broken for me.

i feel this started on the previous firmware update

 I also have spent am hour trying to find an official support ticket system.
