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

    Assuming that:

    • your Linux Laptop uses wlan0 for its wireless connection and your home network uses 192.168.1.x for IP space.

    On the Linux laptop:

    • as root or with sudo – enable IP forwarding and load the change with sysctl -p.

    sudo sysctl net.ipv4.ip_forward
    sudo sysctl -p

    • if you have ufw installed and running – setup a NAT masquerading rule for any hosts forwarding IPv4 traffic to it.
      add this line to /etc/ufw/before.rules file right after the “*nat” line

    :POSTROUTING ACCEPT [0:0]

    -A POSTROUTING -s 192.168.1.1/24 -o wlan0 -j MASQUERADE

    On the mac:

    • set your IP address manually to be on the same LAN as the Linux laptop, but for the gateway address… point that at the IP for the Linux Laptop.

      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’
