Not a question and posting my experience

New XB8 gateway was installed since my old xfinity modem had a few connectivity issues.

Everything was a snap and all devices connected to the new gateway.

But, after a couple of weeks, I realized by printer was not on wifi.  Tried several things,

splitting the bands, going thru docs and even spoke to second tier support.  No luck and

they sent me a tech and he came to my home and told me to move to WPA2 instead of WPA3

and that solved the issue.  Yes, WPA3 is better in terms of encryption.

So, I may resort to using WPA3 and only adjust to move to WPA2 when taking printout since

I hardly take any prints.. 

Hope this may help if someone is scratching their head as to why the new Xfinity modems

may have issues w/ some printers or other devices..
