There is no Realtek WiFi hardware visible in any of the logs shared. There IS a Mediatek USB WiFi device visible in all logs shared and this is missing firmware (as above). The Linux 6.18-rc7 kernel images posted to my test share a few days ago (mentioned in post #4) have the missing firmware added. The latest logs you shared show a Linux 6.17.4 kernel image that does not contain the firmware (although you can always add it manually using the commands in post #2). If you believe there to be Realtek WiFi hardware inside the box you need to pastebin the old vendor kernel dmesg log somewhere so I can maybe see what chip is present.
NB: LE has its own paste server so in the AMLGX images all you need to do is run "pastekodi" and share the URL generated.
