Wifi drops and turns back on.
I am using a Lenovo Yoga 3 14 inch with a BCM4352 802.11ac Wireless Network Adapter.
The Wifi occasionally stops working for roughly 10 seconds and comes back on again. I do a lot of video conferencing, so this is an issue for me. If you could provide a workaround, I would very much appreciate it.

The following procedure applies to all supported releases of Ubuntu that are NOT End of Life (EOL) in the following table:
https:/
Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable) and apply all updates.
In order to gather essential troubleshooting information about your wireless card, please follow this procedure:
Step 1
In the Ubuntu Terminal console , make sure that unlimited scrolling is enabled:
click on Edit > Profiles > "Default" profile > Scrolling. Choose "Unlimited" as scrolling option. Click Close and Close again.
If you are using the Gnome interface, open the Terminal console via "Applications-
If you are using the Unity interface (default graphical user interface in Ubuntu), use the 'search' function on the dash. Or you can click on the 'More Apps' button, click on the 'See more results' by the installed section, and find it in that list of applications. A third way, available after you click on the 'More Apps' button, is to go to the search bar, and see that the far right end of it says 'All Applications'. You then click on that, and you'll see the full list. Then you can go to Accessories > Terminal after that.
So the methods in Unity are:
Press CTRL-ALT-T key combination.
Dash > Search for Terminal
Dash > More Apps > 'See More Results' > Terminal
Dash > More Apps > Accessories > Terminal
Step 2
Please copy-paste the following diagnostic command from the
https:/
website using a web browser (like Google Chromium or Mozilla Firefox) into the Linux Terminal. The command STARTS with the word sudo and ENDS with the word lsmod. So please copy-paste the ENTIRE diagnostic command below from the web browser into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.
Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the diagnostic command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!
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/
Step 3
Please do NOT attempt to send any attachment(s). Please copy/paste the full terminal output at this location:
https:/
The troubleshooters at Launchpad need to see the full Terminal output from running the above diagnostic command.
Step 4
Please also specify the name of the wireless access point that you are trying to connect to (not the model/make of your router).
Step 5
Please also clarify if you installed Ubuntu to the harddisk and are running from a harddisk install OR if you are only testing Ubuntu in a Live CD session.

Your wireless adapter is already working and has detected several
wireless access points.
1) But your wireless access point is sharing the same wireless transmission
channel (channel 6) with OTHER access points which is causing wireless interference!
Please log into the wireless router using a working, WIRED Internet
connection and change the transmission channel to channel 8 in order to
avoid wireless interference.
2) If necessary, please also log into the wireless router using a working, WIRED Internet
connection and also force the router to use Wireless-G speeds (= 54 Mb/s)
which will hopefully stabilize the connection.
3) If the previous 2 modifications do not permanently solve the issue, then your wireless adapter is probably experiencing the following bugs:
https:/
https:/
which is linked to the following error in your Terminal output:
"wl_cfg80211_
The solution for that "wrong mac address" issue seems to be to update the bcmwl-kernel-source to the latest version using a working, WIRED Internet connection.
