Nintendo Switch cannot find network

Hello, thank you for the reply. This Switch 2 is the only device affected. It does not even show my WiFi network as an option on the list of available networks to join, and entering the details manually does not work either. I was able to briefly get it connected by going into the admin portal 10.0.0.1 and changing the channel of my network to 36, which allowed the Switch to see and connect to the network, but Xfinity automatically reset the channel after a few minutes and the Switch disconnected. Now it will not allow me to change that any more and so the Switch can't see my network. 

I have not tried hardwiring, no. I don't have an ethernet cable available at home. 

Any way to fix this and allow me to change what I need to change? 

@user_ypfubk Take a look at a community members steps for a potential fix here https://forums.xfinity.com/conversations/your-home-network/is-anyone-still-having-trouble-connecting-their-nintendo-switch-to-their-wifi/6824b45221d0ff73d55f1f2f. Please let us know if this helps.

This solution applies to an XB8 not XB6 and I do not have the same options available, so it would not fix my situation. However, by splitting my bands into 5G and 2.4g and then manually adding the 5g network and leaving it untouched for 48 hours, it magically started to detect my network and is now connected. No idea how or why, but it works now. 

Thanks for providing us with an update @user_ypfubk. I remember this issue happening upon release, but I am glad you have found a solid fix! It has been about 48 hours since you shared what worked for you. Are things still working well?
