All internet settings on router vanished after I changed the SSID password.
As stated above, additionally, my main PC, now plugged into LAN on router, reads as 'Device is blocked by Access Control in the router'. Other PC will connect wirelessly, and the internet settings ...

You have asked for the Gateway info.
Not seeing how it would be safe to place that in an open forum.
I asked for the "make and model" of the modem/gateway/ONT. There is nothing special or private about that. It is essential detail to help to track down what might be going on on your network.
You say you have a "Charter Spectrum: D3.1 2.5G eMTA". That doesn't show up in the Spectrum system, but it is probably a plain vanilla modem. None of the wifi stuff that would add router capabilities.
The message 'Device Blocked in Access Control,' appears when I enter router management settings at 192.168.1.1, using browser.
This suggests that at some time you enabled the router's setting to block or limit the access to the network.
ADVANCED > Security > Access Control.
You may also have Block all new devices from connecting enabled.
If you cannot use a web browser to access the graphical user interface (GUI) for any reason, the "factory reset" is pretty well our only option.
This view of the empty occurs when I attempt to re-enter the prior known configurations in Advanced> Internet Setup.
There it asks for Internet IP address, DNS Address, and Router MAC Address.
There's normally nothing there that you can fill. The Internet IP address is in the hands of your ISP. Most ISPs will change this from time to time. Very few ISPs hand out permanent IP addresses. When they do, they may charge for the privilege.
The Mac is also a detail that the GUI picks up from the router. It is also written on the router's label along with other useful default details. Unless your ISP tells you otherwise, you rarely need to do anything there.
The DNS is also something often best left to the ISP. Mess with it only when you have good reasons to do so.
The only information that you need to think about if the login credentials (username and, if needed, password) to connect to the Internet.

Thanks for that reply.
Yes, there are devices and P addresses blocked in my access control center, and I review them regularly...on the PC which is, itself, now inextricably blocked.
I had reviewed the block list , then changed my SSID password, just before this issue arose.
In Internet Settings I do have the option to enter a static IP, as well as a static DNS address, alongside the option to have thise things be assigned as dynamic.
Following the prior configs, I have sought to choose Dynamic at each point, selecting the bubble for each 'dynamic' option.
I will try again, just for the heck of it, and see if the device which can access the router will allow me to hit 'apply' after I make the welections for IP address, DNS, and MAC address.
Thanks for the overall walk-thorough of terms.

What does your ISP say you should do with that setting?

The local IP address depends on what your router picks. The MAC address can change because a router may see a different address for wifi over wired.
Why did you set up address blocking?
Messing around with those things can cause trouble Leaving things alone with the default settings works for most of us, especially on a basic router like that.
Those changes can cause more grief than help. You need to understand what you are doing and why you are doing it.

- WantNotTexhNotMar 14, 2025AspirantThanks for all you have said here.
Months ago I signed in and realized that there were tens of dozens of DNS attacks each day.
As my connection was also experiencing unexplained slow speeds, I was frustrated and concerned.
I experienced a better connection after designating the channel I wished each respective SSID to operate on, and determined what worked best for my household with broadcasting/not broadcasting each SSID.
To the issues which brought me here:
I cannot remember if it was a comment from you or the other person, focusing on my PC having been added to the block list, and as I went about the day I remembered that among the changes I'd made just before the crash was a change to the PC's name, one which rather irks me.
Following the change and re-start, both names appeared side by side in the 'About' section of the PC, as well as the 'Allowed Devices' section of the router settings. I had no reason to worry , I thought.
However...after I signed in again, that name change veiled the PC's ID, though neither the IP nor the MAC asdress had changed. Sadly, I had to change the PC name back to that which irks me in to ensure resolution.
I unplugged both modem and router, plugged modem in first waited, then plugged router in, and voila, all systems were a go. (Whew!)
None of my settings were lost.
I will fully concede that there is always the danger of flubbing up my ability to use the router and internet, but I am my only defense against the baddies, so I am trying my best.
Thank you.- michaelkenwardMar 14, 2025Guru - Experienced User

Netgear's firmware is great at creating false reports of DoS attacks. Many of them are no such thing.
Search - NETGEAR Communities – DoS attacks
Use Whois.net to see who is behind some of them and you may find that they are from places like Facebook, Google, even your ISP.
Here is a useful tool for that task:
IPNetInfo: Retrieve IP Address Information from WHOIS servers
If these events are slowing down your router, that may be because it is using up processor time. Anything that uses processor power – event logging, QoS management, traffic metering – may cause slowdowns. Disable logging of DoS attacks and see if that reduces the problem. This does not prevent the router from protecting you from the outside world.
