Wifi repeater AC-LITE

Greetings earthlings,
I have a uap ac lite and i wanted to make a wireless extender. ive tried using travelmate as a uplink and made a AP in the interface but it wouldnt connect. It stays stuck at obtaining ip address. Any suggestions?

What's your other router? And weekday software is running? Maybe you can just use WDS.

Linksys Wrt1900ac stock firmware, i dont know if its (openwrt) firmware is compatible with mesh or 802.11s
