CBR750 Address Reservation and Port Forwarding not working

[BKWayne]

Model: CBR750

FW: V4.6.14.4

Just got this router today. When I go to set static IPs via Address Reservation I'm hit with "400 Bad Request" and this is occurring with several devices.

When I go to setup port forwarding on those devices, I receive no error, but the list of services remains blank and it appears nothing has gone through.

Have ran a firmware update and reboot. No avail.

What browser are you using? Does it happen with a different browser? 

Try a full factory reset and setup from scratch using a web browser and wired PC. 

Be sure to clear out all browser caches before entering the CBRs web page at 192.168.1.1

Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

Are you using the 'pull down' menu to select the service (port) or creating a 'custom' rule?

Port forwarding is somewhat unique in that there is no "Apply" button at the top of the screen and the router WiFi does not go through a restart as it does with so many other changes. (annoying the heck out of my Alarm system.  "Lost WiFi"  "WiFi Found", both texts and emails.)

Using Firefox. Switching to Chrome solved it!

Glad you got it working. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
