Thanks for getting back to me.

 

Since changing the channels, things have been much better. However, things aren’t perfect. I have spent a little time digging around in the router on the computer. I found a setting that said “Disable IPv4 firewall protection” — this box was unchecked. I never found anything labeled “IPv6.”

 

I also found a factory reset button in the advanced section. Should I try this?

I would try the factory reset and set the modem up again from scratch. Use the manual channel configuration as well.

        So, I just performed the factory reset. Now I can't log into my router. When it asks me for the serial number (and I enter the correct number from the bottom of the modem/router),  it tells me that the serial number is incorrect.
