Wi-Fi 7 - improve your OpenWrt One

What you need:

• OpenWrt One
• m2 MTK mt7925 or QCA WCN7850 ath12k - both 80211BE with 6GHz support
• M2 M to A+E adapter
• antennas
• driller (6.5 mm)

Install there latest OpenWrt main (enable drivers) and you have fully open source router with 802.11BE and 6GHz support. Tested both mt7925 and wcn7850 cards.

You can have it for about 100€ - works really good :)
