I saw your post from the att forum dated back in Sept 2016. So your router detected a php hijacking and blocked the packet. That's ok. But.. I would guess your getting attacked all around and over loading your router. If you have a consumer-grade router. I would call att and see if they have anyway of looking to see if your being attacked. Getting a new IP address should help. Login to your router check to see what your WAN/Public IP address.
Try powering off your Router and ASL Node for 3-5 minutes.
Some hackers testing your IP address and router.
The power off is to hopefully get a new IP address.
Google online port scanner. Find one a scan your router to see if any of your ports our open. It should show no port. Filtered ports are bad as well.
