RBR750 403 Access denied after upgrade to 4.6.3.7 firmware
I'm getting a proxy error from the router, and am unable to access its configuration page after firmware update from 3.x version to 4.6.3.7. I factory reset the router, and then I'm able to conne...
I tried Brave, Chrome, and Edge browsers, all with the same effect.
I've isolated the change to what I stated: i.e. I can make the error happen simply by taking the initial default configuration (after walk-through setup) and trying to change the router ip address to 192.169.x.x rather than 192.168.1.1.
The issue happens regardless of whether or not the router is connected to the cable modem.
Modem is Netgear CM1000.
You'll need to keep 192.168.1.1 for now if this doesn't cause a problem.
I recommend you contact NG support and let them know what your seeing when you try changing the IP address from .1.1 to something different.
Unfortunately, this is not a solution for me because I need this specific network numbering topology. Since this worked in previous firmware versions, how do I revert to an older version of firmware? When I try via the web UI, there is no "Yes" button to confirm the "version you're installing is older than the current version" question.
No downgrading isn't supported. Contact NG support and let them know whats happening.
Yikes! What a mess.
Thanks for your help. I guess my best bet is to try to take the set back to Costco and hope that their generous return policy will allow me to get a replacement set that still has the old, working firmware.
