Setting up OLSR mesh on a Linksys ( Assumes a stock standard Linksys out of the box)
1. Download freifunk firmware from (http://www.freifunk.net/wiki/FreifunkFirmwareEnglish) - openwrt-g-freifunk-1.0.2-en.bin
2. Set boot wait on linksys
Web method:
Navigate to web page were you can send pings and type each of these lines one line at a time
;cp${IFS}*/*/nvram${IFS}/tmp/n
;*/n${IFS}set${IFS}boot_wait=on
;*/n${IFS}commit
;*/n${IFS}show>tmp/ping.log
NVRAM method:
telnet into box and type the following
nvram set boot_wait=on
nvram commit
reboot
3. Upload firmware
Give yourself a fixed IP in the 192.168.1.x range e.g. 192.168.1.100
Use tftp to upload firmware
tftp 192.168.1.1
tftp> binary
tftp> rexmt 1
tftp> trace
Packet tracing on.
tftp> put openwrt-g-freifunk-1.0.2-en.bin
Wait for the power light to stop flashing
Power cycle the box
4. Check that the web interface is working. Visit the site http://192.168.1.1 on your web browser - you should see the main freifunk web interface appear
5. Set up the wireless interface
WLAN protocol: Static
Ip Address: 192.168.2.5
Netmask: 255.255.255.0
WLAN Mode: Ad Hoc (Peer to Peer)
ESSID: mesh
Channel: 6
TX Power: 100
6. Set up the LAN interface
LAN protocol: Static
LAN IP: 192.168.4.1
LAN Netmask: 255.255.255.0
Disable NAT: yes
Disable Firewall: yes
7. Set up the WAN interface
WAN Protocol: DHCP
Host name: Lawrence
8. Set up OLSR
HNA4: 192.168.4.1 255.255.255.0
9. Restart the Linksys
You should now be given an IP address in the 192.168.3.x range
You should be able to connect to another mesh access point and even get a default gateway to an internet point, if one exists

An interesting read. Keep up the good work. One quick question here, why you mentioned get an ip address of 192.168.3.x range out of the blue. I don't see any hint in the article that lead to that ip address. Is it a misprint?
Hi,
I did a guide to setup a simple OLSR mesh too. If you guys are interested please take a look at here.
Cheers!
You should turn on the Image verification to eliminate the spam of the plastic surgery crap...and other junk.

Hi, quick question. Does this configuration mean that clients wanting to use the mesh, need to connect to one of the wired connections on the access point. As the wifi side seems to be taken up on a different IP to do all the mesh communication stuff. If i am mistaken, and clients can connect to the wireless also. Please could you explain how? I dont see it being possible with that configuration.
Cheers,
Matt
