Is there a way to set up a separate 2.4-GHz network with my XB8 Gateway?

I switched from Breezeline to xfinity 2 years ago because they had a better internet deal. Shortly after switching, I noticed my U by Moen shower temperature controller began randomly shutting down. Long story short - Moen told me my controller software was not updating because it required a 2.4-GHz connection. The controller would not connect to my xfinity wifi because it apparently randomly switches between 2.4 and 5 GHz. Called xfinity, they told me I needed a dual-band router, which they sent me. However, this router has a preset SSID and password. I don't want to have to reset all the SSIDs and passwords on all my devices. Is there any way to split off a dedicated 2.4-GHz network from my XB8 so that I can keep everything else the same?

user_kzqy0h Thank you for reaching out and sharing your experience. I know if I were in your shoes I would be reaching out too.  Some Xfinity modems, including the XB7 and XB8 models, have limitations when it comes to separating the 2.4 GHz and 5 GHz bands. This is due to a feature called band steering, which automatically connects devices to the optimal frequency band. If you are not using any Xfi Pods, you can try separating the combined 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;

Thank you for the reply. The link you provided doesn't really have enough information to explain how to do this. There are about a dozen channels and two different frequencies each to choose from for 2.4 and 5 GHz. Does it matter which I pick if I turn off automatic band steering? If I do this, how will the two different SSIDs appear initially? Will they each have the same SSID and password to begin with? I fear messing up the connection and being unable to connect to xfinity at all if I don't do this correctly.

@user_kzqy0h These are all great questions and I want you to ask as many as you need :). Instead of trying to adjust the channels on each WiFi band, we want to edit the name of the wireless networks so you can distinguish them from each other while searching for a specific network to connect to. For example, you could rename the 2.4 GHz network "wifi2" and rename the 5 GHz network "wifi5" and keep the passwords the same so you don't have to remember more than one. What are your thoughts?

Sometimes you can avoid the hassle of splitting your wireless bands by changing your security mode from WPA3 to WPA2. WPA3 is newer technology and not all devices are compatible with that security mode. You can find instructions here to change your security mode. What security mode is your modem currently set up with?

My security mode is WPA3. The issue I am trying to fix is enabling my U by Moen shower controller to connect to wifi so it can get a long overdue software update. The Moen tech support people told me the controller needs to connect to a 2.4-GHz signal. I could not connect it to my existing xfinity network. It is the only wireless device I have that has this problem. I suspect Moen's technology is dated, but replacing the shower controller is not an option.

Splitting into two bands, one 2.4-GHz, the other 5 GHz should provide a way out.

Since you are using an XB8 modem, the easiest way to do this is to disable the band steering capability inherent on all Xfinity Advanced Wireless Gateways: 

 

From the Xfinity App-

Edit Wi-Fi Settings

Activate option for "Split Bands"
