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.

What is Multi-Link Operation (MLO)?
Worth comparing29 of 79 listed here
A Wi-Fi 7 device uses two bands at the same time over one connection, instead of picking one and living with it.
Look at instead: whether your phone and laptop are Wi-Fi 7 — nothing older can use this
Full entry → - 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 → - MU-MIMO
What is MU-MIMO?
Table stakes46 of 79 listed here
Lets the router hold separate conversations with several devices at once using different antenna streams.
Look at instead: the stream count on each radio — a 4×4 radio has twice the streams of a 2×2 to hand out
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
