Hello @kb2040
Thanks for reaching out here in the Community!
Since your internet service provider is Xfinity, we would recommend changing your router settings for the 2.4 GHz band from g/n to b/g/n, as customers have stated that this helped resolve their issue.
If you need help configuring your router setting, it'll be best to contact Xfinity Support directly.
Keep us posted on how it goes.
All the best,
Kariza
