Allowing internet access while in AP mode (on mobile)

[atscglitch]

I'm doing a hardware workaround to this using a travel router. It basically gives a 2Ghz wifi SSID that has capability  to pass through an internet connection to those devices on that SSID. The connection can come from a wired cat cable or another wifi signal with the cellular connection (like a phone in hotspot mode). The pi and the controlling device like a tablet will then be on that HooToo SSID with full internet passthrough.

That version also runs a NAS/Samba/DLNA off the USB port. It's USB 5v powered so the pi will provide the power.
