I turned on bridge mode on my router, but now I am unable to access the modem control panel. Is there any way to access it without turning off the bridge mode?
 
In windows try manually entering gateway ip as the modem ip and your computer ip as the next number then in the browser enter the modem ip to see if the login page appears?

Typically modem and gateway ip is 192.168.1.1 and you manually specify computer ip as 192.168.1.2
