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 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-squashfs-r3794.bin flash0.os
CFE> reboot

log into the AP

install USB modules:

cd /tmp
scp 192.168.0.4:/src/kamikaze4/trunk/openwrt/bin/packages/kmod-usb-core_2.6.16.7-brcm-1_mipsel.ipk .
scp 192.168.0.4:/src/kamikaze4/trunk/openwrt/bin/packages/kmod-usb2_2.6.16.7-brcm-1_mipsel.ipk .

ipkg install kmod-usb2_2.6.16.7-brcm-1_mipsel.ipk
ipkg install kmod-zd1211_2.6.16.7+r69-brcm-1_mipsel.ipk

change root password
- ```

```

modify /etc/modules.d

remove encryption modules from 20-madwifi

cd /etc/modules.d
rm 20-madwifi
cp /rom/etc/modules.d/20-madwifi .
vi 20-madwifi

add a file for zd1211:

cat > /etc/modules.d/70-zd1211 <<EOF
zd1211
EOF

modify /etc/init.d

add some lines to S20madwifi:

cd /etc/init.d
rm S20madwifi
cp /rom/etc/init.d/S20madwifi .
cat >> S20madwifi <<EOF

iwconfig ath0 essid www.personaltelco.net/repeater
iwconfig ath0 channel 11
EOF

remove S45firewall
- ```
rm /etc/init.d/S45firewall
```

add a file S90repeater:

cat > /etc/init.d/S90repeater <<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/S90repeater

Modify /etc/config/network to:
- ```
lan_ipaddr="192.168.3.1"
wan_proto=none
```

 Line 4:
-The current methodology for building one of the devices is as follows:



 * load OpenWGT in a normal fashion, either via serial console or via the Netgear web interface

   {{{

CFE> ifconfig eth0 -auto

CFE> flash -noheader 192.168.0.3:wgt634u/wipe-1.img flash0.os

CFE> flash -noheader -offset=3932160 192.168.0.3:wgt634u/wipe-2.img flash0.os

CFE> flash -noheader 192.168.0.3:wgt634u/openwgt-0.06.img flash0.os

CFE> reboot

}}}



 * log into the AP 

 * configure network, e.g.:

   {{{ 

ifconfig vlan0 192.168.0.x up

ip route add default via 192.168.0.1

vi /etc/resolv.conf

}}}



 * wget three ipkg's from [http://downloads.openwrt.org/whiterussian/packages/ openwrt's whiterussian repository] to /tmp: 

   * [http://downloads.openwrt.org/whiterussian/packages/rsync_2.6.5-0_mipsel.ipk rsync]

   * [http://downloads.openwrt.org/whiterussian/packages/libpopt_1.7-4_mipsel.ipk libpopt]

   * [http://downloads.openwrt.org/whiterussian/packages/uclibc_0.9.27-8_mipsel.ipk uclibc]

 * remount the flash read-write: 

   {{{ 

remount-rootfs.sh rw

}}}

 * install the packages:

   {{{

ipkg install rsync_2.6.5-0_mipsel.ipk

ipkg install libpopt_1.7-4_mipsel.ipk

ipkg install uclibc_0.9.27-8_mipsel.ipk 

}}}

 * ssh to the host where the repeater rootfs lives (to initialize the hostkey), if necessary: 

   {{{ 

ssh root@192.168.0.3 

}}}

 * rsync from a copy of the repeater rootfs, e.g.:

   {{{ 

rsync -v -a -H -x --delete root@192.168.0.3:/src/repeater-rootfs/ / 

}}}

 * reboot 



== Testing ==



To test, plug in the HawkingHwu54g radio, either directly or via a USB extension cable (up to 15 feet long, or even further using powered hubs).  Place the HawkingHwu54g where the best {{{www.personaltelco.net}}} signal is available.  Place the NetgearWgt634u where convenient and it provides good local coverage.  Power up the NetgearWgt634u and, after 15-30 seconds, associate your client device to {{{www.personaltelco.net/repeater}}}.  You should receive an address via DHCP in the 192.168.3.0/24 network.  Try loading a web page with your client device and click through the splash page.  Try pinging {{{4.2.2.2}}} and {{{www.google.com}}}.



== Feedback ==



The MississippiNetworkRepeater is in a testing phase.  If you encounter problems or to provide positive or negative feedback, please contact RussellSenior.  Thanks!



== FIXME ==



Need to package up a tarball of the repeater-rootfs.



== OpenWrt Version ==



Experimenting with an OpenWrt-based version of the repeater, aiming for inclusion of the zd1211rw driver.
