Diff for "MississippiNetworkRepeater" - Personal Telco Project

Differences between revisions 11 and 12

The MississippiNetworkRepeater is a NetgearWgt634u loaded with OpenWRT. It uses a HawkingHwu54g USB 802.11g radio as a client to any nearby www.personaltelco.net network and operates its native radio as a local coverage access point.

Building

To build one of the devices:

load OpenWrt Kamikaze (here r6007) in a normal fashion, via serial console:

CFE> ifconfig eth0 -auto
CFE> flash -noheader 192.168.0.5:wgt634u/wipe-1.img flash0.os
CFE> flash -noheader -offset=3932160 192.168.0.5:wgt634u/wipe-2.img flash0.os
CFE> flash -noheader 192.168.0.5:wgt634u/openwrt-wgt634u-2.6-jffs2-r6007.bin flash0.os
CFE> reboot

log into the AP via serial console

set root password:

passwd

configure /etc/ipkg.conf to point at a compatible package archive:

src snapshots http://www.personaltelco.net/~russell/openwrt/r6007/packages
dest root /
dest ram /tmp

install zd1211 packages:

ipkg install kmod-usb2
ipkg install kmod-zd1211

install iproute2 tools because I like them:
- ```
ipkg install ip
```

configure /etc/config/wireless:

config wifi-device  wifi0
        option type     atheros
        option channel  11

config wifi-iface
        option device   wifi0
#       option network  lan
        option mode     ap
        option ssid     www.personaltelco.net/repeater
        option hidden   0
        option encryption none

disable firewall script:
- ```
rm /etc/rc.d/S45firewall
```

modify the lan stanza in /etc/config/network:

#### LAN configuration
config interface lan
        option type     bridge
        option ifname   "eth0.0 ath0"
        option proto    static
        option ipaddr   192.168.3.1
        option netmask  255.255.255.0

add a file /etc/init.d/repeater:

cat > /etc/init.d/repeater <<EOF
#!/bin/sh

echo "Initializing Repeater"

/sbin/ifconfig wlan0 up
/usr/sbin/iwconfig wlan0 essid www.personaltelco.net
while /usr/sbin/iwconfig wlan0 2>/dev/null | grep Access | awk '{ print $5 }' | grep 00:00:00:00:00:00 ; do sleep 1 ; done
/sbin/udhcpc -i wlan0
/usr/sbin/iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
EOF
chmod 755 /etc/init.d/repeater

create a link in /etc/rc.d:

cd /etc/rc.d
ln -s /etc/init.d/repeater S90repeater

turn of wan stanza's dhcp in /etc/config/network:

#### WAN configuration
config interface        wan
        option ifname   "eth0.1"
        option proto    none
