I have 2 Tl-WA5210G access points. I need them to talk to each other. I have had this set-up for years but I do not remember how I did it so I could use some help. The communication is really only 1 way.
I have 1 access point inside that is running directly into a computer running Windows 7.

PC -> Wired Ethernet cable to Lan/POE Injector -> 5210G
Other End ( There is no internet involved )
5210G -> to Lan/POE Injector -> Wired Ethernet cable to an Amped Wireless Router -> LED Outdoor Sign

I need to send different sign configurations to the Led Sign through the CPE’s.
How do I need to set the sign up to do this? I have tried AP to Client and Repeater mode. They do not seem to work.
What am I doing wrong? Or Does someone know how to set it up to work? I know I have a setting wrong but I can’t figure it out. All of the You tube video’s that I can finds to show the setup are in Spanish. Is there one in English?
I would appreciate any help.
