Installing kernel modules for other chipsets

If your USB Ethernet adaptor has a chipset that isn't listed above, it is possible that an available driver/kernel module is available for the WiFi Pineapple MK7.
You can check this by going to the WiFi Pineapple's Web Interface, and going to Modules > Packages, and searching for the name of your chipset.
