I use this machine for two purposes:
Allow my Nexus 7 Tablet (2013) to access the Internet via WiFi, on my wired LAN.
Allow other devices to access the Internet in the same way (5 simultaneously, maximum)
Allow the tablet to access storage devices over WiFi.
(My tablet is connected to a USB keyboard, the system avoids the use of a bulky USB hub).
By default, the "FileHub" RavPower behaves like an IP router, Ethernet WiFi
Ethernet side, it receives an IP configuration via DHCP from the local network (or domestic box).
This configuration allows Internet access through the local network.
WiFi side, the IP address is configured by default: 10.10.10.254
The device's DHCP server can distribute 5 addresses in this subnet.
The tablet is found and connected to the wireless network.
The integrated routing to "FileHub" connects the two subnetworks, and the tablet can access the Internet.
The default SSID is: FileHub-595A, and Wpa key: 11111111
To access the USB devices, just open the address 10.10.10.254 in the tablet Internet browser.
The login is "admin" without password.
Then simply use the controls in the web interface.
The default configuration is printed on a label on the case back.
This configuration is used to test product functionality.
For a more secure use, it is recommended to change the login, password, SSID and WPA key.
Addressing in 10.10.10.x can also be changed, if the Ethernet network also uses this address range, which can happen in a corporate network.
In conclusion, this is very interesting and inexpensive, I recommend it if the need is a Internet routing via a wired network, with access to usb, sd cards, removable disks or over the network.
The free application ES Explorer also allows access to volumes shared via Samba.
The router has other features that I have not looked.
