How to Configure a Wireless Router as an Access Point

Introduction
This document takes UTT AC750W as an example describes how to configure UTT wireless router as an Access Point on Network via an Ethernet cable. (The user has a router already and only wants to use UTT router as a wireless access point.)
 
Prerequisites
1. a UTT Business Router (hereinafter shorted as “the Router"), such as UTT router N518W, AC750W, AC750GW and AC1220GW. Firmware Version: 3.0.0 or above
2. a PC/laptop connected to the Router wirelessly or through an Ethernet cable

Configuration
1. Connect a PC to UTT AC750W’s LAN Port via an Ethernet cable or wirelessly.
 
2. Check the first router's LAN Gateway IP address.
If it isn't 192.168.1.1, just enter AC750W's Web Interface and go to Step 5.
If it is 192.168.1.1, change AC750W's LAN IP address to 192.168.1.2.  (Any IP address is ok, but it should not conflict with the LAN IP of the first router, 192.168.1.2 is merely an example.) Configure as follows:
Enter 192.168.1.1 in the address bar to enter AC750W's Web interface
 
3. Go to Network > LAN, Edit the default LAN IP.
 
4. Change 192.168.1.1 to 192.168.1.2, then click Save.
 
5. Disable Local Area Connection/Ethernet on the PC, then enable Local Area Connection/Ethernet again.
 
6. Enter 192.168.1.2 in the address bar to enter AC750W's Web Interface again.
 
7. Go to Network > DHCP Server, untick Enable, disable DHCP Server
 
8. Connect AC750W’s LAN Port to the first router's LAN Port via another Ethernet cable.
 
Disable Local Area Connection on the PC, and enable Local Area Connection again, after the PC obtains an IP address from router's DHCP Server, the user shall be able to access the Internet.
 
Troubleshoot
1. Avoid DHCP conflict. One broadcast domain should have only one DHCP Server.  As an access point, the DHCP Server function of UTT AC750W should be disabled.
2. The user cannot use the same LAN Gateway IP address in the same broadcast domain. it's better to change the LAN IP address of the device working as an access point.
