Your situation
- You have successfully installed Ubuntu.
You have just downloaded and booted Ubuntu live media.
The latest LTS (see also HWE) or latest non-LTS release are preferred. See the list of Ubuntu releases that are currently supported.)
You upgraded your Ubuntu installation to the latest release that the software updater offered you. WiFi worked before, but not now on the new release.
- You migrated your existing Ubuntu installation to new hardware.
Your problem
- The wireless of your laptop or desktop is not working. You tried switching the wireless switch off and on and you tried rebooting several times, but you don't see any WiFi access points.
- You can see your wireless access point, but you cannot establish a connection.
- You want to analyze the problem, but you don't know where to start or what information you can provide.
This question and answer was written to give people the wireless script that will provide the information needed in most cases to diagnose their wireless issue's.
Related questions
The easiest and most complete method of gathering information to help diagnose wireless issues is to run the wireless info script we created at the Ubuntu Forums to collect all the most common information needed while masking all sensitive data.
Open a terminal with Ctrl+Alt+T and run these commands:
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info &&
chmod +x wireless-info &&
./wireless-info
This will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.
If you cannot connect to the internet with the affected system, including via a wired connection, you will have to move files between it and a system connected to the internet. A USB stick would likely be the easiest method for this.
Post the results on paste.ubuntu.com or pastebin.com, and link to it here in your question.
Further details on the script: GitHub page.
Here is an example of the information that the script will collect:
