I don't think there is a general issue in chromeos/brunch with 5ghz, in general wifi support mostly depends on the support in the linux kernel for you wifi cards and also on the firmware used.
BCM cards are notably known to have no 5ghz support or may require specific firmware files. For the other cards, it is hard to say like that without knowing what kernel module is used.
So what can I do?
I would suggest to:
If not, provide the reference of the adapter that's supposed to have the best support in linux and I will try to have a look at it.
Ok, i'm still a bit of a linux noob. lspci should give me the kernal modules loaded/being used right?
I can research from there the support and what drivers are being used.
Does that sound right?
THANKS
Could you try the build in the "brunch-unstable" repository ? Not sure it will change something but I have updated the wireless regulatory db
OK going to try that. WIll get back to you when I try it.
Actually how do I update via crosh to the unstable version? is that possible, or do I need to start from scratch?
is it sudo update_engine_client --channel=unstable -update in crosh?
UPDATE: figured it out.. cmd is ...sudo chromeos-update -f /home/chronos/user/Downloads/brunch.gz
I dont see a difference on the atheros card, no 5ghz networks.
I have tried 2x BCM cards, 1 ratink & 2x Atheros card and I cannot get 5ghz networks to show up? Despite all these cards supporting 5ghz wireless N. I also tried a Intel card and 5ghz does show up on the intel but that card has no Bluetooth. So I want to keep the BCM card which includes Bluetooth. I saw another user has this issue with BCM but related it to dual booting and fixed by updating grub in the dual boot config. Im only single booting brunch so no grub to update. Thoughts? How can I fix this? Can I change the wireless driver via shell?
