Hi,

What is wrong with the folowing script ("S30mymetwork" in init.d)?
When I run the script, the route is not added (last line), when I type it manually on the console the route well is added (visible via route -n)

The script is:
#!/bin/sh
set -x
. /etc/config/network
WAN_IP="$wifi_ipaddr"

wlanconfig ath0 destroy
wlanconfig ath0 create wlandev wifi0 wlanmode sta
echo WAN_IP $WAN_IP
ifconfig ath0 $WAN_IP
iwconfig ath0 essid "test"
ifconfig ath0 up
route add default gw 192.168.1.1

The command I type on the console:
>route add default gw 192.168.1.1

Any idea, can the default route be deleted by dnsmasq, udhcpc.... ?

Your PATH environment may differ so try to run "route" with full path (/sbin/route).

You couldn't possibly write $wifi_ipaddr in the rest of the script, you had to create a variable to reference another variable? Anyways .. If you set the following in your /etc/config/network:

wan_ifname=ath0
wan_proto=static
wan_ipaddr=192.168.1.x
wan_gateway=192.168.1.1

You can then change your S30mynetwork script to a much simpler:

#!/bin/sh
wlanconfig ath0 destroy
wlanconfig ath0 create wlandev wifi0 wlanmode sta
iwconfig ath0 essid "test"
ifup wan
