OpenWRT Router Pre-configured for Smartphone Tethering

In this guide, I'll be using:

iPhone 12 Pro on iOS 15.1.1 as my tethering device
Raspberry Pi 4 with OpenWRT version 21.02.1
64GB Sandisk micro SD card

The goal with this guide is to create a pre-configured OpenWRT router that:

Is plug and play to provide out-of-the-box smartphone tethering
Supports both iPhone and Android (comment below if you are having any issues).

Github "Verified" commits using GPG key with private email

It's nice to see a Verified message next to each commit for peace of mind.

Using GPG or S/MIME, you can sign tags and commits locally. These tags or commits are marked as verified on GitHub so other people can be confident that the changes come from a trusted source.

Install latest gpg

If using a mac use homebrew

Creating GPG keys and subkeys

There are the steps to create GPG key pair and the additional steps to create a subkey.

Create GPG keys

gpg --full-generate-key
Please select what kind of key you want:
