You may have an option, but if your ISP does not support it you are effectively blocking your connection. What does your ISP say you should do with that setting? 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. What did you block? An IP address? A MAC address? Both of these can change. If that happens your setting will block your own access. 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. Disclaimer: Just another user with time on their hands.

Had you started with that as the issue, you might have saved yourself a lot of grief. 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. Disclaimer: Just another user with time on their hands.

Sounds like one of those things that Windows may have foisted on you. Again, start with the problem and try to work out what caused it and how you can fix that. Other approaches run the risk of knock-on damage somewhere else. 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. This is always recommended when you have been messing around with a network. Each bit of he network picks up its cues from the things it see when you turn it on. It begins with the modem. That detects the IP address on the Internet and establishes the connection. The router then sees this and adapts its own settings accordingly. After that, other devices can work out how to connect to your local network and the Internet. Disclaimer: Just another user with time on their hands.

Hard to follow what is going on there.

Where do you see this message?

As to the subject "All internet settings on router vanished", where are you looking?

Other PC will connect wirelessly, and the internet settings fields are empty there as well.

Empty in what? Are you using a web browser and the graphical user interface (GUI)?

No efforts to reset with prior i formation have been successful.

What do you mean by "reset". You have factory reset the R6220?

How do I perform a factory reset on my NETGEAR router? | Answer | NETGEAR Support

Finally, what modem/gateway/ONT (make and model) connects the router to the internet?

  "Where do you see this message?"
  
  The message 'Device Blocked in Access Control,' appears when I enter router management settings at 192.168.1.1, using browser.
  
  "As to the subject 'All internet settings on router vanished', where are you looking?"
  
  In the router management section titled "Internet Setup"
  
  No, I have not reset the router using factory settings.
  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.
  
  The Modem is from Charter Spectrum: D3.1 2.5G eMTA
  Model: ES2251
  
  You have asked for the Gateway info.
  Not seeing how it would be safe to place that in an open forum.
  
  Thank you for parsing out my inquiry.

    If the router will not allow access, there is no opportunity to make any changes. Although a Factory Reset is often thought of as a Last Resort (because it erases any configurations the user may have done - in my case about two hours of typo-ridden entries), this seems to the situation here.
    
    I would Factory Reset this unit and start from scratch.
