    How to connect to wifi?

    Hello,
    I'm a total non-tech person who somehow managed to follow the recipe and install Ubuntu 20.04 on my old macbook pro 2011. However i see no way to connect to wifi automatically. The instructions on the page Ubuntu Desktop Guide » Networking, web & email » Wireless networking »"Connect to a wireless network" don't work as there's nothing pertaining to Wifi on the 'system menu' on the top right.

    I then went ahead and installed Ubuntu 20.10, thinking that maybe wifi would be easy to connect on that one but, same thing. I still have this version on my machine.

    I did a search and whatever results i found involved terminals and commands which are foreign to me. Is there a relatively easy way for me to make wifi work on my computer, or would it just be easier to find someone and have them fix it for me?

    Thank you,
    Ana

    Why 20.10? It only has 9 months support and so is EOL (End of life) in July. If you are non-technical then I suggest you wipe the install off and do a clean install of 20.04. This is LTS (Long term supported) for 5 years and is rock solid.

    Does the system have a make and model, please?

    HI, thank you. I explained above that I switched to 20.10 in the hopes that it'd be easier to connect wifi. I'd have gladly kept 20.04 if I'd been able to make the wifi work (I still have 20.10 on my machine at the moment)
    I'm not sure what you mean by system? I downloaded the Ubuntu versions on this page https://ubuntu.com/download/desktop

    If you're talking about the computer, it's a Macbook pro 13 inch, early 2011. Is that what you're asking?

    Is there a relatively easy way for me to make wifi work on my computer, or would it just be easier to find someone and have them fix it for me?
    Here I am! I'm ready, let's go!

    If you can see nothing about wireless, then it typically means that there is no existing wireless driver. Let's check and find out.

    The 'relatively easy' way is to use the terminal. It gathers information quicky, easily and accurately. Please open a terminal Ctrl+Alt+t and type:

    Code:
    lspci -nnk | grep 0280 -A3
    That pipe symbol | is on the right side of my US keyboard on the same key with \. lspci means list all the PCI devices and grep 0280 means limit the result to wireless.

    Press enter. The command will show needed details about your built-in wireless card. Post the result in your reply and we'll proceed.

    Here is the result from my machine, for example:

    Code:
    chili@T440p:~$ lspci -nnk | grep 0280 -A3
    03:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 83)
    	Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c270]
    	Kernel driver in use: iwlwifi
    	Kernel modules: iwlwifi
    That's how we know if you have an Intel card, a Realtek card, an Atheros card, etc., and which exact device.

    Please see: https://ubuntuforums.org/showthread.php?t=2214110

    In short, get a temporary internet connection by ethernet, tethering or whatever means possible and, again, in the terminal:

    Code:
    sudo apt update
    sudo apt install -y firmware-b43-installer
    Reboot and enjoy your wireless!

    Does your computer have an ethernet port? Plug a cable into it and the other end into your router. It ought to connect automatically.

    Re: How to connect to wifi?

    Just saw the link. Thank you very much, you basically solved the whole thing for me.

    What i still don't understand is why this isn't integrated into the installation. Very grateful to be able to test Ubuntu, but easily configurable wifi would be a giant step towards user friendliness outside of the tech community. I've a feeling there's going to be a spike in Ubuntu downloads very very soon.

    Thank you again
