Use a cellphone as a wifi adapter

AndroGR · 2021-10-15 20:17:37

When i first came to Linux I expected myself to have my hardware mostly recognized, which was true. However i recently finished building my computer and because i didn't like Windows, I decided to go with Linux directly. I downloaded Arch, since i had it already installed in multiple VMs, my laptop and my mobile phone (Don't ask about the last one lol) as my first distro, just to realize i didn't have any internet connection in the live session ! I ended up just switching to Debian, which i liked, but i still want Arch in my machine. To get internet connection in Debian, however, i had to do what's described in this post: https://easylinuxtipsproject.blogspot.c … ernet.html
My question is, how can i do that on a live session of Arch as well? I also use Android.

This one says i need to install a package.However i expect Arch to work without it, because even Debian did work without any other package. I will try i guess : )

The package is part of the live system. You should be able to follow it, you just have to not forget to install it into the actual system.

Did you explore why? It might be easier to solve this problem directly rather than skirting the issue with tethering. What is the wireless adapter hardware (output of lspci and / or lsusb)?

To answer the original question. Connect the phone to your computer with a USB cable, set the phone to wireless tether mode.
From a shell, start dhcpcd as root.

The adapter works in Arch just like in every other system: The kernel finds it, but doesn't know what is it supposed to do. The chipset is RTL88x2BU, which isn't supported since long ago. There is nothing wrong with the kernel or the system, just the companies.

Another quick question, i'm running out of USB ports, should I use the option Copy to RAM first?

Um, huh?

He has one usb port (macbook failure, I guess) and cannot boot from there and attach his phone at the same time (and apple adapters cost apple amounts of money…)
So he wants to use

* copytoram=        If set to "y" or just "copytoram" without arguments,
                    all SquashFS are copied to "RAM". If you add the package
                    "pv" to the packages.x86_64 it is used to display the copy
                    progress.
                    Default: (unset)

https://gitlab.archlinux.org/mkinitcpio … bootparams to be able to remove the USB key after the boot process (and attach the phone) what sounds reasonable - but I've never tried.

In doubt it'll just fail and you learned something new ;-)

There's a kernel module for that in the AUR - if you can download the source and have in stored somewhere accessible to the live system you should be able to get wireless up and running.
