I have a raspberry pi, and as you or may not know, the pi doesn't support wifi.

Been googling to no avail, everyboy just wants to use that 3g, but all I want is that wifi.

Is there any way to turn my N900 into a wifi dongle for my pi?

Cheers

Re: Bridging wifi

Or even if you can do it with an N9?

Re: Bridging wifi

It is possible with both but easier with N900 I will make a tutorial in the next days. At the moment I am pretty busy.

Re: Bridging wifi

I believe if you should search " how to tether the raspberry pi" you might find some usefull tutorial or something. Does the raspberry pi recognize the n900 when you plug it in?

Re: Bridging wifi

the issue is, all those tutorials just bridge usb > 3g

I need usb > wifi

Re: Bridging wifi

I hope I did understand you right.

Here a small example that it looks like your rasperry pi is connected to the wlan:

Requirements:
N900 with iptables (powerkernel)

Assuming your networks are:

Wlan 192.168.1.x
USB 192.168.2.x

PC in wlan network 192.168.1.10
N900 in wlan 192.168.1.14 and usblan 192.168.2.15
raspberry pi (RPI) in usblan 192.168.2.14

PC

Code:

route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.1.14 dev wlan0

N900

Code:

route delete default



iptables -t nat -A PREROUTING -s 192.168.1.0/16 -i wlan0 -j DNAT --to-destination 192.168.2.15



iptables -t nat -A PREROUTING -s 192.168.2.0/16 -i usb0 -j DNAT --to-destination 192.168.1.14

When you want to use only the local lan (no internet), you don't need the iptable rules. Instead you can activate forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forwarding

RPI

Code:

route add default gw 192.168.2.15 dev usb0

When you need internet don't forget to add a DNS.
