Re: [arch-general] Wifi challenge with new Lenovo Yoga C740
Ok... I managed to get wifi working ...

Many newer laptops have soft-buttons for wifi/sound/etc.. that traditionally would just save states between boots. I have 2 SSDs in my laptop, one with the original W10, the other with Arch. I've noticed the soft-buttons are configured differently depending on whether I boot windows (once a month for updates) or a normal boot of Arch. (behaves the same with openSUSE as well) I wouldn't be surprised if the wifi soft-button defaults to off. I have a light within 4 independent buttons that show the state of wifi, sound, etc... Double-check yours when you boot the Arch installer. With the arch installer, if the wifi chip is enable, it should be picked up and enabled automatically. As others have said, save the output of lspci -v (write it to a usb drive or something) and post the output just to confirm that there isn't some left-field chipset used (doubt it, but that would confirm) If you have a RJ45 connection for a wired connection, that's always an option. -- David C.

Re: [arch-general] Wifi challenge with new Lenovo Yoga C740
Hi Leo, did you check "ip l" when booting the arch live image, to see if the interface is really not detected? Did you try unblocking it with rfkill? Maybe there is a hardware switch on your device, or a key combination with fn + f8 or similar? Otherwise, it might be helpful if you'd provide the output of lspci and lsusb, so we can check what the exact wifi model is. Also something like dmesg|grep network or dmesg|grep wifi might be helpful :) If Ubuntu has working wifi, it should be possible with Arch as well :) Greetings, Lukas from Germany
Re: [arch-general] Wifi challenge with new Lenovo Yoga C740
Hi, I would love to get some pointers what to change to get this working, otherwise Ill return the laptop and look for a more cooperating one. Can you provide the output of lspci -v regarding the wirleess chipset? Regards Bjoern
[arch-general] Wifi challenge with new Lenovo Yoga C740
(nb - I did post this question also on Reddit) So I decided to replace my aging ASUS laptop with a shiny new one. After long considerations and lurking in various places I decided to go for this - not very cheap - one. One of the reasons is that I this time intend not to remove Windows and keep the possibility to occasionally boot into Windows, My long experience (> 40 years with various kinds of ***x such as Unix, Ultrix and Linux) doesnt prevent me from encountering a challenge now and then. Maybe I am getting too old ? :) Anyway - the challenge: I seem not to be able to get Wifi working when booted from the Arch installation image. Wifi works fine with Windows, but also with the live image of Ubuntu 19.10. Also Manjoro doesnt see wifi when starting 'wifi-menu'. However, just as in Ubuntu, the driver 'iwlwifi' has been loaded... (The wifi in this laptop is Intel) I would love to get some pointers what to change to get this working, otherwise Ill return the laptop and look for a more cooperating one. Thanks a lot in advance.
