my Wifi can't find any networks

Asked by Andy Pegg on 2016-07-03

My Wifi can't find any networks... they do exist as I have multiple devices connected to them, and my laptop is currently 1 metre away from the router

After running the following commands:

sudo apt-get update; sudo apt-get install usbutils pciutils hwinfo grep rfkill; sudo lshw -C network; rfkill list; sudo iwlist scan | grep -Ei 'chan|ssid'; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nnk | grep -iA2 net; lsusb; nmcli nm status; sudo lshw -short; uname -a; sudo updatedb; dmesg | grep -E '02:00|80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|ireless|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|ound|p54|prism|rror|rtl|RTL|rt2|RT2|rt3|RT3|rt5|RT5|rt6|RT6|rt7|RT7|usb|witch|wl';sudo dmidecode|grep -E 'anufact|roduct|erial|elease'; iwconfig; grep -E '80211|acx|at76|ath|b43|bcm|brcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|wmi|witch|wl' /etc/modprobe.d/*; cat /var/lib/NetworkManager/NetworkManager.state; sudo hwinfo --netcard ; ps -aux|grep -E 'wpa|icd|etwork'; netstat -rn ; cat /etc/resolv.conf; ls -lia /boot; grep tmpfs /etc/fstab; ubuntu-support-status; sudo update-pciids; sudo update-usbids; sudo lsmod

I got this result:

Those cheap Broadcom chips are easy to setup

Please try the following workaround procedure:

https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/273424

Please run these Terminal commands using a working, WIRED Internet connection (using an ethernet cable):

sudo apt-get update

sudo apt-get install firmware-b43-installer

sudo apt-get dist-upgrade

Then run this Terminal command:

sudo gedit /etc/modprobe.d/blacklist.conf

Using the gedit editor, scroll down and add the following configuration line inside the blacklist.conf file:

blacklist bcma

Your wireless adapter (Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)) should use the b43 driver instead of the bcma driver.

Then reboot your PC and retest wireless.

The name of your wireless access point is the name of your access point in the dropdown list of available wifi points in your vicinity while using the wireless connections GUI ....
