How to Save Multiple WiFi Networks on Miyoo Mini Plus
The Miyoo Mini Plus only saves one WiFi network at a time. Here are two ways to save multiple networks so you never have to re-enter a password when switching locations.
The problem
The Miyoo Mini Plus running OnionOS only stores one WiFi network at a time. When you connect to a different network, like your phone's hotspot, it overwrites your home network credentials.
Next time you're home, you have to re-enter the password all over again. This happens because OnionOS's WiFi settings UI writes a fresh wpa_supplicant.conf file with only the network you just connected to, replacing whatever was there before.
There are two ways to fix this: editing the config file directly, or installing an app that manages multiple networks for you.
Method 1: Edit wpa_supplicant.conf
The quick, no-install method. You edit the WiFi config file directly to add multiple network entries.
Open File Explorer
On your Miyoo Mini Plus, open the File Explorer app from the Apps menu in OnionOS. If you don't have it, enable it from the Package Manager.
Navigate to /appconfigs/
Browse to the /appconfigs/ directory. This is on the device's internal storage, not the SD
card. You should see a file called wpa_supplicant.conf.
Add your network blocks
Edit the file so it contains a network={} block for each WiFi network you want to save:
ctrl_interface=/var/run/wpa_supplicant
update_config=1
network={
ssid="HomeNetwork"
psk="your-home-password"
key_mgmt=WPA-PSK
priority=2
}
network={
ssid="MyPhone"
psk="your-hotspot-password"
key_mgmt=WPA-PSK
priority=1
}The priority field is optional. Higher numbers are preferred when multiple saved networks are in range.
Save and restart WiFi
Save the file and reboot your device. It will automatically connect to whichever saved network is in range. When you move to a different location, it switches to the next available network without any manual input.
Method 2: Install Better WiFi app
A community-made app that gives you a proper UI for managing multiple WiFi networks. It handles the config file for you so there's no risk of the system overwriting your changes.
Download Better WiFi
Download the latest release from the Better WiFi GitHub
repository. Extract the zip file to get the
BetterWifi folder.
Install SimpleTerminal
Better WiFi requires SimpleTerminal. Install it from the OnionOS Package Manager if you haven't already.
Copy to your SD card
Copy the BetterWifi folder into /App/ on your SD card.
Launch and add networks
Open Better WiFi from the Apps menu. The app provides a menu to scan for networks, add new ones, and switch between saved networks. It also has backup/restore functionality.
Which method should I use?
| Edit config file | Better WiFi app | |
|---|---|---|
| Setup time | 2 minutes | 5 minutes |
| Installs needed | None | SimpleTerminal + app |
| Survives WiFi UI changes | No | Yes |
| Network scanning | No | Yes |
| Best for | 2-3 fixed locations | Frequent network changes |
If you just switch between home WiFi and your phone's hotspot and won't touch the WiFi settings menu, Method 1 is the fastest fix. If you connect to many different networks or want a friendlier interface, Better WiFi is worth the extra setup.
FAQ
Does this work on the original Miyoo Mini?
No. The original Miyoo Mini doesn't have built-in WiFi. This guide is specific to the Miyoo Mini Plus.
Does this work with firmware other than OnionOS?
This guide is written for OnionOS. Both methods described here are specific to OnionOS. Other custom firmwares may handle WiFi configuration differently.
Will my saved networks survive an OnionOS update?
Major OnionOS updates may reset the wpa_supplicant.conf file. Back up the file to your SD card before updating. The Better WiFi app includes a backup/restore feature for exactly this situation.
Why does connecting via the WiFi menu erase my other networks?
OnionOS's built-in WiFi settings UI writes a fresh config file with only the network you just connected to. This is a known limitation of how OnionOS handles WiFi. It wasn't designed for multiple networks. The Better WiFi app works around this by managing the config file directly.
Can I set a priority order for my networks?
Yes. In wpa_supplicant.conf, add a priority field to each network block. Higher numbers are preferred when multiple saved networks are in range.
