1 year ago Not a bug, Intel wireless devices cannot be used in AP mode on the 5GHz band and those devices are not DBDC (dual band dual concurent) , it's either 2.4 or 5 GHz at a time, not both together. Sorry.

1 year ago Intel is managing the regulatory domain rules entirely inside their proprietary firmware, it listens to the environment to learn where it is located (based on the IEEE 802.11d regulatory hints sent out by the APs in range, this also means that you'll have a problem if one of your neighbours sends out a wrong country code!). There is absolutely nothing that could be done by linux and its drivers, if there really is a problem, you would have to discuss with with Intel engineers via bugzilla.kernel.org (or their own bugtracker(?)), so they can release new firmware blobs.
But there are several other things to keep in mind as well:
/lib/firmware/iwlwifi-ty-a0-gf-a0* with newer versions, which may (or may not) have fixed this, as iwlwifi isn't really in the prime focus of OpenWrt, the versions might be lagging behind.

1 year ago I updated the firmware used on these devices to the most recent one supported by the device in 00ce1c05877ac38f5ff00c1c2ce3468d5168f76c. Maybe this helps.
Thank you @pkgadd for the detailed explanation, I will close this ticket now.

1 year ago 英特尔完全在其专有固件中管理监管域规则，它侦听环境以了解其位置（基于范围内AP发出的IEEE 802.11d监管提示，这也意味着如果您的邻居之一发送了错误的国家/地区代码，您将遇到问题！linux 及其驱动程序绝对无能为力，如果确实存在问题，您必须通过 bugzilla.kernel.org（或他们自己的错误跟踪器（？））与英特尔工程师讨论，以便他们可以发布新的固件 blob。
但还有其他几件事需要记住：
- 您似乎在虚拟机中运行OpenWrt，这引入了另一个潜在问题，因为iwlwifi对PCIe总线的细节非常非常敏感（即使在裸熨斗上，这些卡可能无法在所有PCIe插槽中工作）。至少对于测试，在没有虚拟化的情况下在真实硬件上进行测试 - 只需从USB记忆棒启动OpenWrt即可。
- 您可以替换为较新的版本，这些版本可能（也可能没有）解决此问题，因为iwlwifi并不是OpenWrt的主要焦点，版本可能会落后。
/lib/firmware/iwlwifi-ty-a0-gf-a0*- 正如 Coudu 提到的，没有办法在 AP 模式下使用 AX210（除了 2.4 GHz，以非常有限的方式）
- 正如 Coudu 提到的，一个收音机、一台 Mac、一个 PHY - 这张卡一次只能调谐到一个频道（和频段）。
Thank you for your complete explanation. I would like to know how you learned so much knowledge. To be honest, I feel that there are still many things I don't know in computer science. What videos do I need to watch to learn better, or other ways? Also, I would like to know why people like you who maintain open source code do this? What benefits can one gain from such hard work? Don't you have to work?

1 year ago 我将这些设备上使用的固件更新为00ce1c0中设备支持的最新固件。也许这会有所帮助。
谢谢你的详细解释，我现在就关闭这张票。
Thank you, but I have tried it before and it's not very useful. It seems that OpenWrt cannot be used as a WiFi connection device, and the effect is much worse than hard routing.

1 year ago 这不是一个错误，英特尔无线设备不能在 5GHz 频段上的 AP 模式下使用，并且这些设备不是 DBDC（双频双并发），一次是 2.4 或 5 GHz，而不是两者兼而有之。 不好意思。
Thank you, I understand
Describe the bug
OpenWrt version
r23691-9194fcb1a4
OpenWrt target/subtarget
x86/64
Device
QEMU Standard PC (i440FX + PIIX, 1996)
Image kind
Self-built image
Steps to reproduce
1.Enable wifi in the wireless section of the Network tab
Actual behaviour
No response
Expected behaviour
I hope the wireless module can become better and better used, after all, the current wireless modules are indeed a bit stretched.
Additional info
There are no available 5G frequency bands in China
/etc/config/wireless （default only radio0）
config wifi-device 'radio0' option type 'mac80211' option path 'pci0000:00/0000:00:10.0' option channel '3' option band '2g' option htmode 'HE40' option txpower '22' option cell_density '0' option country 'CN'
config wifi-iface 'wifinet0' option device 'radio0' option mode 'ap' option ssid 'OpenWrt2' option encryption 'none' option network 'lan'
(manual add radio1 but ) config wifi-device 'radio1' option type 'mac80211' option channel '4' option path 'pci0000:00/0000:00:10.0' option hwmode '11g' option band '5g' option htmode 'HE40' option txpower '20' option cell_density '0' option country 'CN'
Add a radio in/etc/config/wireless yourself, and the other one will be kicked out
