This is a method to use your PC internet connection on your tablet.
This was tried with an N810 with an Ubuntu laptop.

Preparation
refer to the instructions given here [1] :
on host: open (with root privileges) file /etc/network/interfaces
add the following at the end of the lines:
auto usb0 iface usb0 inet static address 192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255 up echo 1 > /proc/sys/net/ipv4/ip_forward up iptables -P FORWARD ACCEPT up iptables -A POSTROUTING -t nat -j MASQUERADE -s 192.168.2.0/24 down echo 0 > /proc/sys/net/ipv4/ip_forward down iptables -t nat -F POSTROUTING
Enter rescue mode
Put your tablet on. As soon as the "Nokia" screen appears, press the "home" button of your tablet, the one that is just under the camera, and keep it pressed until the "Mer" screen appears.
Shortly after this screen appeared, the rescue mode will appear. It gives you five choices: - start Mer; - activate console; - act as an ethernet USB gadget; - act as a serial USB tool; - reboot.
Select the option that says "act as an ethernet USB gadget".
A console screen will scroll, then the Mer screen will appear.
Connect the USB cable between your PC and the Tablet.
configure your network interface
On host: open a shell, and type
modprobe usbnet
then
sudo ifdown usb0
then
sudo ifup usb0
You should get no message from the shell.
find your DNS
(on host) In Ubuntu, they should be in
/etc/resolv.conf
On the Tablet: open the shell, and type
sudo echo nameserver A.B.C.D > /etc/resolv.conf
[where A.B.C.D represent the figures in your DNS.
test by pinging
on host: open a shell, and type
ping 192.168.2.2 -c 5
It should return five lines proving that contact was established with the Tablet.
This means that you are ready to use the internet connection of your computer.
