I can confirm the same behavior using the following router with an XBox 360.

Model: TP-Link TL-WR1043N/ND v3
Firmware Version: LEDE Reboot 17.01.4 r3560-79f57e422d / LuCI lede-17.01 branch (git-17.290.79498-d3f0685)

When disabling WMM Mode as suggested by the OP my XBox 360 is able to obtain an IP address from the router and connects to the internet as expected.  

The same behavior has also been discussed in the forum including more details and screenshots, reported by mitza97.  Unfortunately this thread ended with a change of hardware.

I can provide additional details if needed.
