I am attempting to set up and configure my access point TL-WA801ND. I have ran an ethernet cable from my router/modem in my house to my workshop about 150 feet away (may be up to 200 feet of cable). I have connected this to my access point and powered it up. I attempted to access with my ipad and iphone but it does not appear in the wifi list. I then took the access point back to the house and made the direct connection via ethernet cable to the router/modem. I can see the tp-link wifi but when I attempt to connect the ipad and iphone show the wifi  but continue to spool and will never connect. The wifi shows an ip address of 169.254.184.113 and a submask of 255.255.0.0 . 

Since it never connects nor connects to the internet, I cannot log into the internet nor log into TP link to configure the AP.  

Any suggestions as to how I may get the AP to connect? I am challanged with this so you may need to offer additional instructions.
