Hi everyone! I'm using this BCM43142 with the AUR driver broadcom-wl-dkms.
Does anyone knows how to use this card in 5GHz mode? My router works on both 2.4 and 5GHz mode. If I try for example
sudo iwconfig wlp3s0 channel 100
it says
Error for wireless request "Set Frequency" (8B04) :
SET failed on device wlp3s0 ; Operation not supported.
Does it even supports 5GHz mode? The card seems to support it but I don't know if the driver support it as well:
iwlist wlp3s0 freq
wlp3s0 32 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Channel 12 : 2.467 GHz
Channel 13 : 2.472 GHz
Channel 14 : 2.484 GHz
Channel 36 : 5.18 GHz
Channel 38 : 5.19 GHz
Channel 40 : 5.2 GHz
Channel 42 : 5.21 GHz
Channel 44 : 5.22 GHz
Channel 46 : 5.23 GHz
Channel 48 : 5.24 GHz
Channel 52 : 5.26 GHz
Channel 56 : 5.28 GHz
Channel 60 : 5.3 GHz
Channel 64 : 5.32 GHz
Channel 100 : 5.5 GHz
Channel 104 : 5.52 GHz
Channel 108 : 5.54 GHz
Channel 112 : 5.56 GHz
Channel 116 : 5.58 GHz
Channel 120 : 5.6 GHz
Channel 124 : 5.62 GHz
Current Frequency:2.472 GHz (Channel 13)
Every help is appreciated! Thank you!

according to this, only 2.4 is supported by the driver

Since this wireless nic works well with linux-firmware from linux 4.X, I cannot find the solution to get 5GHz work well.
But I found another solution to get this work, maybe.
First, download a package from this URL:
http://h20564.www2.hp.com/hpsc/swd/publ … nvOid=4192
then unzip the .exe, copy and rename the file ended with _US.txt to brcm43241b4-sdio.txt, and use this as the NVRAM of bcm43241 FW.
Finally, change region to your country, and get 5GHz work, so does AP Mode in 5GHz.
Hope that this solution helps you.
