Nighthawk cax30 Control panel access failure.

I've successfully registered the MAC address with Xfinity and now have internet access, however 192.168.0.1, 192.168.1.1 and "routerlogin.net" do not work on ANY device. "Server not found" is all I'm getting. I love that I was able to finally get a new router working for a lousy 2 and 1/2 year old router that started slowly crapping out months ago, but it's rather useless to anyone not connected via Ethernet. I like my networks set up with my own configurations, not default silliness that anyone nearby might accidentally connect to. 

 

Nighthawk app keeps insisting that I connect to the router's wifi in order to connect. I AM ALREADY. On three devices so far, yet all three Nighthawk apps on all three devices are still saying there is a problem connecting to the router's wifi, and forcing me to open the wifi settings, which are already connected to the router's wifi! 

 

What happened to just being able to open "routerlogin.net," or 192.168.1.1 (or 0.1) and having it open the damned control panels as long as you have an Ethernet cable connected to the router?????!!!!!!!!!!

 

Sigh. Rant over... for now...

 

Any help is greatly appreciated. Thank you in advance.

    Factory reset has worked for me with my CAX30 or 80 with one ethernet connected PC behind the CAX. MS Edge browser and navigating to 192.168.1.1. 

     

    If pressing the reset button for 15 seconds then release and you can't get in at 192.168.1.1 after say 1  or 2 minutes after the modem comes to ready, try a 30-30-30 reset on the modem with out the ISP coax cable connected. Then try to access the web page. If you can then, reconnect the ISP coax cable quickly as the CAX may auto reboot if the cable isn't connected.

    You may have blocked one of yoru wireless devcies 

    Try to unblock it. 

     

    If you set up the NH app or SPC for use with the cax30, Then you'll need to control that fuction on the NH app. If you want to use Access Controls via the WEB UI in a browser, you'll need to factory reset the CAX30 and setup from scratch using a web browser at 192.168.1.1. After that, wireless or wired PC will beable to use Access controls thru the WEB UI.

      Well, the very first attempt I tried to use was using the IP's and neither one, nor "routerlogin.net" would connect. In fact, NOTHING would work at all until I went to xfinity.com and registred the MAC address. Now we have internet, and BLAZING at that, but I can't change ANY of the default settings using either of the IP's, routerlogin.net OR the Nighthawk app.

      And, no, nothing has ever been blocked in the wireless configuration, since I can't even access that.
