If you’re the kind of person to modify every device you own, you’ve likely messed with router firmware before. Unfortunately, the Google Wifi is set up to be simple and easy to use, with no complex settings (and few advanced settings). It’s also not easily flashable like your old WRT54G was.
Fortunately, the GaleForce project aims to fix some of the shortcomings of the Google Wifi. It’s an open source project that modifies the system to allow for changes without affecting the standard functions of the router. You’ll be able to do things like change the gateway IP and set up a VPN.
Unfortunately, the mod does require opening the router and basic knowledge of Linux command line. Hit the source link for the full info on how to set up the GaleForce project on your Google Wifi and let us know if you manage to get it done!
