If you were following those instructions, the AP would be connected to your computer and not the lan until all the changes were made at which point you unplug it from your computer and plug in a lan cable (from your router) into one of its lan ports (not the wan port).
If thats what you have done then yes, you will have access to it thru the ip address you assigned to it.
Needed a way to get wifi from in the house out to the pole barn. Barn is about 50'
from the house and 75' from my current router. (Metal roof and sides with a few windows)
If I hold the cell phone up to the window I can get two three bars on the wifi.
Decided to create an access point using a router.Got a TP=Link TL-WR1043NDV2 router. Here on out referred to as AP
Unboxed the router, disconnected my ethernet cable from my current router and hooked to the AP.
Logged in to AP. Went to lan page and changed IP address to 192.168.1.100
Had to reboot AP. Rebooted and went to Wireless page changed my wireless network name to XXXXXXX (Name of my home network)
Went to DHCP page and turned off DHCP.
If have a cable connect between router and AP I can access the AP loging. (192.168.1.100( If I remove the cable I CAN NOT access the AP.
I have made sure the wireless is ON the AP and can see the light. But acts like wireless isn't working.
Are you trying to use it like a wireless bridge or are you going to have a cable running between it and the original router and use the new one like an AP?
If you are going to use it like a wireless bridge then you need to go into the configuration and enable WDS bridging and put in your network info. After you do that, and reboot, and disconnect the cable from it you should be able to get to it.
A wireless repeater is going to be slow, even if you have a perfect signal. If you have less than a perfect signal then it can be painful. Also if you have many wireless devices it can be painful, and if you have channel competition with neighbors it can be really painful. Using a wireless repeater cuts your available bandwidth in half right off the top. If you have to go wireless between buildings it is much better to use a wireless bridge than to use a repeater.
And as wireless bridges go it is better to use a dedicated wireless bridge than to try to bridge off the Wifi in the first location.
