I know it's been a year but here's how I do it (I have win10 & droid). Connect Ethernet cable PC to router WAN. Hotspot or turn on tethering app. From here on everything is done on PC. Connect to phone. Go into Network settings then change adapter settings. Locate adapter currently using to connect. Right click, click properties. Click share tab, Ethernet You may need to reset router but as long as PC & Ethernet stays connected you should have internet on everything that is connected to router. I'd recommend USB tethering if possible because it's much faster than Bluetooth & wifi connection to "server".

I tested using RE305 with IOS.  IOS doesn't pass multiple IP to RE305 for clients, additionally RE305 cannot NAT its client IP back to IOS hence IOS doesn't work.

 

Also noticed IOS wi-fi 4 (max 300MB)  and USB also limited to USB 2.0 hence tethering speed may be worse even if it works.
