Some Devices Unable to Connect to WiFi Gateway XB8 because of Wi-Fi Channels in Use Error

A few days ago 3 of my devices stopped connecting to WiFi at the same time, while my other devices are fine.

When it tries to connect it returns an “Unable to join the network - This network is operating on Wi-Fi channels in use by other nearby networks. Restarting your wireless router may allow it to automatically choose the best channel to use, and may resolve this problem.”

I’ve downloaded a wifi scanner and there are other WiFis nearby using the same WiFi channels. Since I have an XB8. I can’t manually update the WiFi channels to fix it. I’ve restarted the gateway and it continues using the same WiFi Channel. I called support and they say they can’t change the WiFi Channel on their side either.

Those devices that are having issues connecting to my WiFi have no issues connecting with any other other WiFis. I even re-enabled my xfinitywifi hotspot for my gatweay and have those devices connect to it temporarily to connect to the internet. It is on a WiFi channel not in use by any other WiFis but on the same exact gateway.

How do I go about fixing this if the Xfinity Gateway isn't picking a new channel, it is disabled in the admin tool, and Xfinity support can't make that change? Why are only the newer gateways blocked from making these changes?

Just in case someone has the same issue, this is how I was able to resolve it somewhat. I did figure out that it was my 2.4 GHz wifi that was the problem. Since I have an Xfi Pod my wifi is not split out and all have the same network name. When I disabled the 2.4 GHz wifi in the admin tool, my devices were then able to connect to wifi using the 5 GHz. But I can't disable that Wi-Fi since most devices use that.

A Comcast tech stopped by to help resolve the issue and he suggested we try to lower the security mode from WPA3-Personal to WPA2. Once that change was made the devices were able to connect to Wi-Fi automatically, however those devices were connecting to the 5 GHz and not trying to connect to 2.4 GHz anymore. I've had the XB8 gateway for months and set to WPA3 and never had this issue till a few days ago. Not sure why lowering the security mode fixes or changes that.

Hello, @JJBC2002! Thanks for taking the time to post on our thread about the devices not being able to connect. I have some Smart lights that can only connect to the 2.4 network so understand exactly where you are coming from. I am glad to hear you were able to get this fixed with the Technician's help. Here are the steps to take for this type of situation for everyone.

1. From a computer or device connected to the Gateway, open an internet browser and access the Admin Tool at http://10.0.0.1.
2. Once logged in, select Connection and then Wi-Fi.
3. Select EDIT at the end of the row for the 5 GHz Frequency Band.
4. Select Disable and then SAVE SETTINGS.
5. Complete setup of the WiFi device(s) using the device’s app
6. Go back into the Admin Tool and re-enable the 5 GHz band. It’s important that you re-enable the 5 GHz band to keep your WiFi network functioning optimally. Xfinity xFi Pods will remain offline until both bands are enabled.

Do you have any further questions for our team?

WILL THE PROBLEM RESOLVE ON IT'S OWN?

I'M VERY COMPUTER ILLITERATE AND SO AFRAID OF MAKING MATTERS WORSE.

THE INTERNET IS WORKING FINE ON MY ANDROID COMPUTER, IT'S ONLY MY IPAD THAT'S HAVING THIS PROBLEM.

IF I TAKE MY IPAD TO AN XFINITY STORE WILL THEY BE ABLE TO FIX THIS PROBLEM?

Hi, @user_1wbvgj. I see you are having a similar issue on your end. I understand you aren't too familiar with the settings or how to make any updates on your end. You could visit the store, however, it'd be best to troubleshoot this while you home. This way we test the results while you are online. We'll be glad to provide some assistance here. Can you confirm if you're also using a Xfinity Gateway (router/modem combo)? If so, do you share the same Wi-Fi name and password for all your devices?

@XfinityRay It’s not even letting me log in, as it keeps saying my username is incorrect. Why are multiple people even having this problem anyways?

Hello @user_u6hqf7. Can you provide me the details of where you are having the login issue please? This tread is mainly about connecting certain devices to the Wi-Fi having problems, but you stated you are having a log in problem which would be different. Happy to help, but I need more information on what problem you are having please? It would also be helpful to create your own public post with the details, so we don't fill this unrelated post with information related to your problem please.
