• MississippiNetworkRepeater

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 .
    scp 192.168.0.4:/src/kamikaze4/trunk/openwrt/bin/packages/kmod-zd1211_2.6.16.7+r69-brcm-1_mipsel.ipk .
    ipkg install kmod-usb-core_2.6.16.7-brcm-1_mipsel.ipk
    ipkg install kmod-usb2_2.6.16.7-brcm-1_mipsel.ipk
