I suddenly need a wired connection for a job starting very soon but it won't be hooked up for quite some time. I have my neighborswifi password though. Iknow this is a longshot, but would I be able to use my laptop to change a wireless connection into a wired connection?

It's an older desktop Mac managed by the company. My laptop is an HP omen 15 with arch Linux on it

sudo sysctl net.ipv4.ip_forward

sudo sysctl -p

Those do not enable forwarding. One prints the value of forwarding and the other loads the config file.

To set it temporarily

sudo sysctl net.ipv4.ip_forward=1

To set it permanantly, edit /etc/sysctl.conf (or add a config file to /etc/sysctl.d/). You only need to add one line that reads 'net.ipv4.ip_forward=1'
