NOAO1AA#ABA (2 letter O's)is an invalid model/product, I think it is N0A01AA#ABA (2 zeros). Anyway, your machine is
HP Pavilion 23-q113w TouchSmart
which shows it only has Integrated Bluetooth 4.0 and Wireless LAN 802.11b/g/n featuring 2.4 GHz 1 x 1 technology part # 792204-001.
That means it supports 2.4GHz networks only. Quick fix: allow your new Xfinity router to broadcast dual bands (2.4GHz and 5.0GHz) then your machine should see 2.4GHz network to allow you to connect. How, please log in to it to change or ask your provider.
Other quick option: Use the following adapter (or many similar around)
