I've been having problems with the connection dropping at random times during the day. Going into the modems logs. It always give me the following 2 messages under the firewall logs:
|FW.IPv6 FORWARD drop , 269 Attempts, 2019/3/17 12:10:46||Firewall Blocked|
|FW.IPv6 INPUT drop , 17 Attempts, 2019/3/16 19:58:55||Firewall Blocked|
I also get these messages in the event log:

After that I have to reset the modem if I want to get my internet back to working.
When I try a web address within the diagnostic tools in the modem it self I get the website I try to ping doesn't work either.
I know it's not a problem with my devices because as soon as I switch to my phone's mobile hotspot things works fine again, both on my phone and computer.
My computer is not connected via WiFi but via Ethernet cable. All devices in the house whether on WiFi or Ethernet loses internet connectivity when this happens.
I've tried to disable the IPv6 firewall of the modem. This doesn't fix it.
I've now deactivated the IPv4 firewall as well but this potentially leaves the modem open for attack which is kind of scary to me.
It is starting to cost me money this problem, because I am online teacher I don't have 10min to wait for a modem reset to happen when I get this issue. I am using my phone's data right now but it is happening so frequently now that I've run out of data on my phone.
I've contacted tech support this morning and they insist the problem lies with me, but if that was the case why would everything work the moment I switch to my phone's internet using a hot spot. The tech I talked over chat with today frustrated me to the point where I am considering finding a different ISP.
Anyone knows how to fix this problem?
I'm having this exact same problem, same errors in my arris xb6 that happen exactly when I lose internet connection and the light goes red for awhile.
