Dear Expert,

ANyone has the software copy of NEC NTA 3110 ADSL modem router manual,
if so, please send it to me.
I want to know the exact admin login web page IP in order to set back
the modem from bridge mode to router mode.

I try 192.168.1.1 is not working for the NEC router( that is  working for CISCO or other  router only)

Anyone knows the NEC's router login page IP, please let me try at my side if you know the IP.
Be reminded the NEC NTA 3110 router is no reset pin at the back of the device and
has one RS 232 console port, and I don't know what  the function of the port is.
Peple say in google search that port is using to outdated 56k modem access or using to control the modem internal setting but still confusing to me which fuction is correct.

Please send it to me if any manual or information about the IP of router of NEC NTA 3110

Please advise
