I want to get Wifi N-only work with my Ubuntu 14.04 on Macbook Air 2013-mid which has BCM4360 802.11ac so it should work well with Wifi N-only also in Ubuntu 14.04. In Ubuntu
- In Software and Updates > Additional Drivers, I see
Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary).
- MacbookAir6,2. I find the serial number by
sudo dmidecode -s system-product-namebut I get also a notice that something is broken
MacbookAir6,2 Invalid entry length (0). DMI table is broken! Stop.Why getting such a notice about broken thing?
lspci -knn |grep Net -A2gives the following so the answer here should apply but not; only difference is that I have ac wlan but they have newer with bgn.
Output of the
lspci -knn |grep Net -A2
03:00.0 Network controller : Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) Subsystem: Apple Inc. Device [106b:0117] Kernel driver in use: wl
- Router TP-link tl-wr1043nd v2 is in Wifi N-mode only.
- Same hardware on OS X works with the Wifi N-mode only, so Ubuntu should also work with it.
- You can set the band be Full HT40 (=20+20 MHz) or Dynamic 20/40kHz where your ultrabook will use 40MHz band because of Wifi N-only setting.
I do have
b43 wifi card. I did the following based on the answer here, which enables slower wifi standards (B, G) but not N. The other thread has a case where the wireless device does not support Wifi N only, but my device supports it, so not relevant here.
sudo update-pciids sudo apt-get install firmware-b43-installer % reboot sudo modprobe -r b43 sudo modprobe b43 sudo rfkill unblock all
Configurations that work but outside of the thread
- AC-only (not tested)
- NG-mixed with Dynamic 20/40 MHz or with Full HT40 (20+20 MHz), where Ubuntu uses only G band.
- Slower bands
How can you Use Wifi N-only with Ubuntu 14.04 on Macbook Air 2013-Mid?
