Ok Folks, I've been struggling with this as well and I can provide some information and help.
BACKGROUND: First of all, there are at least four versions of the Broadcom BCM43602 SoC which is supported by the brcmfmac driver: Source: https://wireless.wiki.kernel.org/en/users/drivers/brcm80211 BCM43602 14e4:43ba Supported in 3.17+ BCM43602 14e4:43bb Supported in 3.19+, 2 GHz device BCM43602 14e4:43bc Supported in 3.19+, 5 GHz device BCM43602 14e4:aa52 Supported in 4.2+, “raw” device You need to run lscpi -nn to determine which one you have installed. I happen to have the first one which ends on 43ba. For a long period of time I was not able to get 5Ghz running on my wifi. Running on 2.4Ghz Wifi was fine but the speeds were limited. SOLUTION: As it turns out, if you have ANY bluetooth device connected to your laptop, the chip will reserve the 5GHz spectrum and your WiFi will only work on 2.4Ghz. Weird. I know... My advise to you is to remove ALL bluetooth devices completely from your Bluetooth manager. I am not talking just turning off your bluetooth devices. I am talking about complete unpairing them from your laptop. In my case, I had a bluetooth mouse. I unpaired it from my laptop and immediately, my WiFi switched to 5Ghz! Hope this helps anyone who is struggling with those chips. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1487524 Title: 14e4:43ba Broadcom BCM43602 not seeing 5Ghz range To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1487524/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
