Sometimes access to a WiFi or bluetooth LAN is unavailable and cellular data is just too slow or doesn't provide you with access to the desired networks.
Reverse tethering is a simple solution to share your PC's network connection with your Pre / webos device (typically over a USB cable via USB networking) It is called "reverse" to distinguish it from what most call tethering, which is sharing your device's mobile provider network with a PC.
First on webos device, if it is not done already, enable USBNet.
usbnet enable (if usb networking is not already on) reboot
On linux workstation: (enable NAT, turn on IP forwarding, assign an IP and activate the usb interface)
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward ifconfig usb0 inet 192.168.0.2 up
(On webos device -- use novaterm, ssh, or terminal app)
route delete default route delete default route add default gw 192.168.0.2 (optional) echo nameserver 10.0.1.123 > /etc/resolv.conf ping google.com
