Should it be USB-WiFi/home/AP_Mode/hostapd-WiFi7.conf Lines 29 to 32 in ea94a61 Should channel be the center frequency? 36 is the start channel for 80MHz channel 42. NetworkManager actually takes the start, though it seems hostapd should take the center?USB-WiFi/home/AP_Mode/hostapd-WiFi6e.conf Lines 40 to 41 in ea94a61 |

Hi @Klaaktu This question is about band 4 (6 GHz) and not really WiFi 7 per se, right? Try channel 65. Also, here is a link to an example hostapf.conf in a new repo that I just opened a few days ago. I think it will have information that will help you. I do need to go back and do some editing but I think it will help. Let me know. |

Hi sorry for the late reply. I finally almost completed my setup (MT7921aun, Netgear A8000) and experimented with the channel parameters. I have one last bug but more on that later... This question was about the There are 3 issues:
So I changed them to below and hostapd works. P.S. TBH |

@morrownr My 6GHz AP is not broadcasting for some reason. Both my laptop (MT7922, NetworkManager) and Pixel phone cannot see my AP by scanning. But they can connect to it as a "hidden network". |

Okay, the 6 GHz lower channels seem to be good to go. Here is a link to an example I have made recently while bringing up a new driver for the rtl8852cu chip: https://github.com/morrownr/rtl8852cu-20240510 Look for the file: hostapd-rtl8852cu.conf That is a known good example. Some of the he lines near the end of the document may need to be different. Hope this helps. Let me know if you get it going and I'll look at modifying the 6e example. |

@morrownr I found out why. 6GHz AP discovery is quite different (802.11ax 26.17.2.3). For 6GHz only AP, in-band discovery must be used: The (primary) channel must be one of the preferred scanning channels. Either FILS Discovery or UPR should be enabled. |

My head hurts. Well, compiling hostap is not that hard. |

Hahaha me too 😂 I feel like hostapd has quite little hand-holding, had to look up so many things... |

MT7921aun driver doesn't support UPR, and Arch hostapd package didn't compile with FILS (ugh...).
