I am posting new thread because old thread was marked as "solved" (and there is no way to reply to it), but it is not the case.
I have the same issue - gateway router losing list of connected device
Thanks for reaching out to us on our Comcast Business Support Forum, Orbix!
The solution was posted at the bottom of that thread https://forums.businesshelp.comcast.com/t5/Equipment-Modems-Gateways/Can-not-see-Connected-Devices/m.... I apologize for the confusion. I'd be more than happy to help get that firmware updated. Do you mind sending me a private message with your full name, address and, the phone number listed on your Comcast Business Account?
I look forward to hearing from you soon!
Yes, I am totally confused! I reread that thread and still do not see any solution. Please respond here so that others can see solution. I realize I can private message you. I choose to message in public so everyone can see solution. Thanks!
I understand and, I appreciate wanting to have the solution posted for everyone to see!
The manufacturer of our Cisco model modems has identified a technical issue impacting some of the devices. This is not a safety concern. However, it may affect the device's features like seeing connected devices for example. I'd need to take a closer look at your modem to see which model it is and verify it has the latest bootfile updated. We highly suggest not sharing your information while on a public post which is why I requested that you send me a private message.
I hope to hear from you soon!
We need to place a device in the DMZ but because we cannot see any devices, we cannot move forward. What is the solution -- or the process for getting a solution?
We have a Cisco DPC3941B, hardware revision 1.0.
DOCSIS Software Version:dpc3941b-v303r20421771-190327a-CMCST
This seems to be an issue that has existed in some form or another for several years. Can we get a reliable fix?
