means the manufacturer doesn't list it, which isn't the same as the product lacking it.
OpenWrt
No support found. Checked against OpenWrt's own Table of Hardware, which carries no qualifying row for this model. That is a weaker statement than "this router cannot run OpenWrt" and a much stronger one than silence.

Wi-Fi features
- OFDMA
What is OFDMA?
Table stakes50 of 79 listed here
Splits a channel into smaller slices so several devices are served in the same instant instead of taking turns.
Look at instead: streams per radio and channel width — those set the ceiling OFDMA divides up
Full entry → - Beamforming
What is Beamforming?
Table stakes37 of 79 listed here
Shapes the signal toward where a device actually is, rather than radiating evenly in every direction like a bare bulb.
Look at instead: where you physically put the router — placement beats every antenna trick on this list
Full entry → - 160 MHz channels
What is 160 MHz channels?
Table stakes47 of 79 listed here
A double-width channel that roughly doubles throughput when the airwaves are clear enough to sustain it.
Look at instead: whether the band has room for it — on 5 GHz that almost always means DFS
