I installed Xubuntu 20.04.1 and I noticed when it is startup (booting) that are two information (errors?) shown of the screen. I thinked that this is only a problem with Xubuntu system but on Ubuntu 20.04.1 I had also this same informations when I run dmesg command in terminal. I installed also Ubuntu 18.04.5 but in this system I have also these errors? I think that on Ubuntu 18.04.5 I have more errors that on Ubuntu 20.04.1. This is from dmesg on Ubuntu 18.04.5 system: [ 25.402xxx] brcmsmac bcma0:1: brcms_ops_bss_info_changed: qos enabled: false (implement) [ 25.402xxx] brcmsmac bcma0:1: brcms_ops_config: change power-save mode: false (implement) [ 26.711xxx] brcmsmac bcma0:1: brcmsmac: brcms_ops_bss_info_changed: associated [ 26.711xxx] brcmsmac bcma0:1: brcms_ops_bss_info_changed: qos enabled: true (implement) [ 13.771xxx] b43: probe of bcma0:1 failed with error -524 I erased some data with "x" because I don't know if it safe to write these kind of information public. I am beginner. One of the Launchpad user told me that this is not error. Okay but I have problem with my Wi-fi. This don't work sometimes. I found the fix. I musted to change in panel configuration of my router channels for 2.4 Ghz. It had auto option enabled. I musted limited to 3 channel because when this was high value my wi-fi doesn't work. I think that this is problem with brcmsmac driver because on bcmwl-kernel-source I don't have this problem on bionic (Ubuntu 18.04.5). I have this same problem on Ubuntu 20.04 and 20.04.1. I had also problems with bcmwl-kernel-source on Ubuntu 20.04.1 after some update but maybe this is fixed now. I don't know because I switched back to bionic. Some terminal output: uname -a 5.4.0-65-generic #73~18.04.1-Ubuntu SMP Tue Jan 19 09:02:24 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux lshw -C network *-network description: Wireless interface product: BCM4313 802.11bgn Wireless Network Adapter vendor: Broadcom Inc. and subsidiaries configuration: broadcast=yes driver=brcmsmac driverversion=5.4.0-65-generic lsb_release -crid Distributor ID: Ubuntu Description: Ubuntu 18.04.5 LTS Release: 18.04 On lsusb output I can see Broadcom Corp. BCM2070 Bluetooth 2.1 + EDR. So this is a bluetooth card. I don't know if it the same device. I think that bluetooth and wi-fi is supported by this same device but like you can see there are different names. On lspci -nnk output BCM4313 802.11bgn Wireless Network Adapter Kernel driver in use: bcma-pci-bridge Kernel modules: bcma Can you fix it? Broadcom users have a lot of problems on Ubuntu system. Maybe if you fix brcmsmac driver this will be not problem anymore. Sorry if this doubled bug, maybe someone in the past report this.
