Re: Packet Loss at Level3/Comcast Handoff

Hello John,

I am having an issue with connectivity from time to time, usually after booting up my PC. I am running Windows 10. Occasionally when I open Firefox, I receive an error message "can't find the server at ___", but I can connect to sites such as YouTube and Google just fine. I've tried just about everything I can think of: Checking my firewall settings, IPv4 and IPv6 settings, used ipconfig, flushdns and even sfc, run anti-virus scans, made sure my PC is up-to-date, etc. I read the thread where you helped several people resolve issues with Comcast blocking traffic from port 80 and thought I may be experiencing this probleam as well. Let me know what you think. Thanks in advance.

Re: Packet Loss at Level3/Comcast Handoff

Sorry for the belated reply. I did some digging around online to try to find some possible solutions. As far as I can tell, it had something to do with my router assigning IPv4 addresses to my connected devices through DHCP. I only have 3 devices connected to my router (2 via ethernet, 1 via Wi-Fi), so I assigned static IP addresses to those devices and have not had any problems within the last month. Thanks for the offer to help. If I encounter any other issues, I will be sure to use the Xfinity forums.
