I started to think that I had a cheap hand. did I enter the password? I tried it multiple times and found that I was wrong, not a cheap hand, it seems that there is a problem. If you need to check the model of your device, you can use lspci to check the model of the WIFI chip. after BCM4313 and GOOGLE, I thought that the driver had crashed, it seems that the driver has to be installed again, but this problem has been accidentally solved from an article. the article is written by a foreigner as follows: So, the latest ubuntu is out with the latest linux kernel and broadcom brcmsmac drivers. as it happens the brcmsmac drivers suck. you can see the list of active wifi networks but won't be able to connect to them. if the output of: lspci-k | grep brcmsmacstmdes: Kernel driver in use: brcmsmacThen you have this problem too. to solve this, you'll need to install broadcom-sta driver and blacklist the default kernel one. sudo apt-get install bcmwl-kernel-sourceThen open/etc/modprobe. d/blacklist-bcm43.conf and add these lines: blacklist brcmsmacblacklist bcmaRestart and check that: lspci-k | grep wlincludes: Kernel driver in use: wlThat shocould fix your wifi. hope ubuntu devs fix this and push out updates soon.
The Great God is Niu X. after learning, I am dedicated to my classmates who are struggling with it and can solve this problem quickly. Next we will roughly translate this content. 1. after entering lspci-k | grep brcmsmac in the terminal, if the following sentence appears, you can use the following method to solve the problem of no Wi-Fi connection. 2. after sudo vi/etc/modprobe. d/blacklist-bcm43.conf, add the following sentence, it is recommended to back up before editing, do not stop. Blacklist brcmsmacblacklist bcma3. restart your computer and run the following command to view the displayed driver, such as the Kernel driver in use: wl. try again using WIFI. The connection should be available. This should be a ubuntu bug and we hope to solve this problem and update it in the next version.
