So i decided to setup my old DLink D615 T1 running (stock Dlink firmware) as repeater with Archer C20 V4 as my main router thats running OpenWrt 19.07.7. When i connect to the repeater's wifi it cant obtain an IP unless i give a static IP to the device trying to connect. If i disable password for the repeater`s wifi it works just fine it gets an IP and connected with internet working. I cant even access the repeaters admin page with password enabled wifi.
This is my first time setting up a repeater so dont know where i am going wrong here.
