N900 Ad-hoc WiFi Hotspot
 Working solution
It may be noted, that scanning for networks on the N900 seems to disconnect everything. So starting wlancond seems to be a bad solution, better stop it.
 Old article
This method works but is not usable for more than a proof of concept because it suffers 40% packet loss at close range between the N900 and the laptop.
 On the N900
- Enable extras-devel
- Install iptables at a terminal with root access:
apt-get install iptables
- Install kernel-power-settings (see the detailed installation instructions):
apt-get install kernel-power-settings
- Connect to the Internet with GPRS
- Setup iptables to allow forwarding:
echo 1 > /proc/sys/net/ipv4/ip_forward iptables -t nat -A POSTROUTING -o gprs0 -j MASQUERADE
- Bring up te ad hoc wireless network:
iwconfig wlan0 mode ad-hoc channel 3 ifconfig wlan0 192.168.4.15 up iwconfig wlan0 essid N900
 On the Client
Simply connect to the ad hoc wireless network.
In this configuration, a DHCP server is not run by the N900, so addresses will have to be manually assigned to clients.
Note that on Android devices, a patched "wpa_supplicant" file may be necessary to see the network.
