password is invalid NOT

Same problem for me, I have Xfinity Gateway, my WiFi name and password have not changed. Confirmed on xfinity app and logged into admin 

what’s the solution?

@XfinityEmilyB​ 

Again, we have an Xfinity Gateway

Network name and password have not changed in years.

On or about July 15 the 2.4Ghz devices cut out. “Wrong network password” was the result when reconnecting.  NOT new devices.

 HP printer came back after rebooting the modem again on July 24.  Also now a GPS  has reappeared on the device list.  Wife’s device,  she’s not here to try connecting.  A garage door monitor will not reconnect with the response still wrong password.

Extremely frustrating.  Lots of my hour spent.  Happy to have contact finally with a tech.  Those that think that “service” is useful in every situation are clueless.

@stevej99​ I have the same exact issue. Please let me know if you figure out a solution. I will do the same.

@XfinityEmilyB​ I have the same exact issue. I also created a post but have not received any help on the issue.  Here are the details:

For the past 12-18 months, my home network has been working flawlessly. I have an Xfinity XB8 (CGM4981COM) gateway and an xfi pod to ensure full coverage across my wide house; the gateway is on one side and the pod on the other. A significant portion of my network consists of roughly 30 2.4 GHz smart devices (switches, plugs, and light bulbs), which are essential for my son's independence as a paraplegic.

However, over the last week, something has changed with the XB8 gateway. The 2.4 GHz devices that previously connected to XB8 are no longer able to establish a connection. Interestingly, the 2.4 GHz devices on the other side of the house, connected to the xfi pod, are still working perfectly. All 5 GHz and 6 GHz devices continue to connect to the XB8 gateway without any problems. I'm aware that band splitting isn't an option because of the xfi pod setup.

I've already performed multiple reboots of the gateway. Do you have any insights into what might have changed with the XB8 gateway, or what I can do to resolve the connectivity issues for my 2.4 GHz devices?

Oh yeah, one more thing. I also noticed that the port forwarding settings on the XB8 gateway were deleted.  So I am "suspect" that the the 2.4 settings were modified during some update to the XB8 gateway. I have heard rumors that an update occurred recently.

Hello @stevej99 thank you for providing the details. If you could send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account, I'd be more than happy to look into this for you.

I am having the same issue myself as well as paying for 1.3 MBPS down and am lucky on a good day to Hit 700 and i often fluctuate in speed. I have many screen recording on different devices showing I hit 700mbps down on one device and the other 900mbps. They are the top speeds then they drop back to 200mbps. Sadly I cant upload the video via links etc. As i have said i think there are some nationwide problems going on that make me wonder if someone in another country is messing with the Xfinity network!!
