Internet Connection Issue with MacBook and Windows PC

Hi Team,

I am a new user and I'm currently experiencing a specific internet connection issue.

While my other devices like my iPhone and iPad are working perfectly, both my MacBook and Windows PC are unable to access the internet.

They show as connected to the modem/Wi-Fi, but there is "No Internet" status.

I have already tried the following troubleshooting steps:

  • Restarted both the MacBook and Windows PC.

  • Power cycled (reset) the modem multiple times.

  • "Forgot" the Wi-Fi network on both computers and reconnected.

Despite these efforts, the issue persists only on my computers. Could you please look into this and provide further assistance?

Thank you!

Hello junxu78 thanks so much for taking the time to reach out here via our Xfinity Forums! Is this still a concern for you? This does sound like a very interesting issue. Can you confirm that the Wi-Fi network you are connecting to on the mobile devices is the same network connected to on the MAC and PC? We have a great resource here on the forums as well for internet troubleshooting.

Did you get this resolved?

I recently encountered a similar problem with an upgrade to the Xb8 gateway.   Are you connecting to the 2.4 GHz network? And which protocol? e.g. 802.11n   On your Windows PC you can find this information on the WiFi network settings page.  I don't know where to find this on a MAC - sorry.

My hunch, from researching this on the net, is that the Channel Mode for the 2.4GHz network needs to be set to b/g/n.  For me it's stuck on g/n/ax.  However, Xfinity no longer allows us to control this setting ourselves.  You can find this on the Gateway's control pages accessed through your browser to the Gateway IP address.

I'm curious as to whether you're seeing the same things I am.
