Enthusiast - Level 1

Verizon's newer USB730L modem works well with the ASUS RT-AC5300 as long as you're not using as your private IP space. Settings within USB730L accepted changing the default IP space on the modem but after a restart kept defaulting back. Resolved by changing my RT-AC5300 routers LAN space.


RT-AC5300 Router Steps:

1.) Change private IP space of RT-AC5300 to non-overlapping space (e.g. Verizon default is and defaults back after a restart (Default: Previous DHCP leases will expire in 24hrs)

2.) Ensure RT-AC5300 router has correct default gateway to new space, mine did not automatically update and was still even though my IP space was

3.) Select USB Application > 3G/4G

4.) Enable USB Mode and Select USB Device (USB Modem) and leave all settings at default

5.) Within WAN Menu/Level (same as above) Select Dual WAN and change Primary WAN to USB

6.) Apply and wait for restart then proceed
