I have an X86J4105 Odyssey, running Ubuntu 21.04 (fully up-to-date, kernel 5.11.0), and I need to setup a 5 GHz Wifi access point using hostapd. This does not work, because the 5 GHz channels are either disabled or listed as “No IR”, which means “No initiating radiation” (i.e., it can connect to an external 5 GHz access point but it cannot create one by itself).
How do I get rid of the “No IR”, so that the system allows me to create a 5 GHz access point?
I can create a 2.4 GHz access point on this system, but that is not good enough for my usecase.
I suspect this is a driver issue, but I’m not sure.
The exact same hostapd/dnsmasq configuration works on a Raspberry Pi 4, so I’m confident it is some hardware, firmware or driver issue - Not a hostapd configuration error on my part (also, 2.4 GHz works).
Edit: There was also some additional iwlwifi driver info I forgot to paste:
Selected output from dmesg | grep -i wifi:
[ 4.200358] iwlwifi 0000:00:0c.0: loaded firmware version 46.6f9f215c.0 9000-pu-b0-jf-b0-46.ucode op_mode iwlmvm
[ 4.275764] iwlwifi 0000:00:0c.0: Detected Intel® Wireless-AC 9560 160MHz, REV=0x318
The “Detected” board is a Wireless-AC 9560 according to the driver, but lspci reports AC 1550i - Is this a problem (or are these two names for the same or compatible hardware)?
Edit 2: This is probably not a problem, since I found the string extern const char iwl9560_killer_1550i_name[]; in the iwl-config.h file (from the kernel driver’s source code). Probably different Intel commercial and internal/technical name.
Below this line is some information about my system:
