Hey @Paris1
Thanks for reaching out here in the Community!
Could you tell us who your internet service provider is? If it's Comcast or ATT, 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.
Keep us posted.
All the best,
Kariza
