Configure TP Link N750 As An Access Point

This set up is a little trickier than most routers.

The two main things you need to do:

1) Under Network>LAN change the IP address of the router to a range on your network. For example, say your network is on 10.10.10.xxx. You need to change the router’s IP to something like 10.10.10.250. That way you’ll be able to access the router’s menu. If not, your router will be on 192.168.0.1 (default) and you won’t be able to get into the router’s menu from your 10.10.10.xxx network.

2) Disable DHCP. Since the main router is typically serving up the IP addresses, you don’t want the TP Link router to issue IPs.
