I got an Airlink 101 AR430w router from a dude at a McHenry County Software Craftsmanship meeting. He had already flashed it with DD-WRT and like a moron I tried a web firmware upgrade to the latest build 21061 – without knowing what it fixed. Then you turn it on, it powers up, and sits there. Reading: Airlink AR430w flashing instructions

After 2 days of on-and-off messing around, I finally got a telnet session going into the router. You need to have an isolated network so DHCP doesn’t play tricks – I used a laptop on WiFi with an unused Ethernet port and manually set the IP to 192.168.1.10, to play in a different subnet than the WiFi 192.168.0.X. Power up the router, telnet 192.168.1.1 9000
and Putty supplied the Ctrl+C when needed.
I downloaded the new flash files (for the one release older, 14896), set up the Windows TFTP32 server, and killed the laptop firewall. Then I started getting this timeout error. Flashes would not work.
DD-WRT> load -r -b 0x80041000 linux.bin Using default protocol (TFTP) TFTP timed out 1/15 Can't load 'linux.bin': operation timed out DD-WRT>
Over and over. Read OpenWRT pages, Could not get it to work. As I read, most folks blamed network issues – maybe I had too much going on in my laptop with Virtual Box virtual NICs. I even tried the recommended DrayTek Router Tools from this article on DD-WRT – which worked great, but STILL timed out.
Finally took my brother’s Linux box I am configuring as a firewall – another fun project. It has two NICs, eth0 to 192.168.0.X, internal net, and eth1 I configured as 192.168.1.10.
eth0 Link encap:Ethernet HWaddr 70:71:bc:77:XX:XX inet addr:192.168.0.239 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::7271:bcff:fe77:6140/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth1 Link encap:Ethernet HWaddr 00:22:3f:e9:YY:YY inet addr:192.168.1.10 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::222:3fff:fee9:4973/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I installed tftp and tftpd, and added this config (based on this thread in the DD-WRT instructions)
mike@filter:~$ cat /etc/xinetd.d/tftp service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /tftpboot disable = no }
This crashed the router again. Was in one of the instructions. Not sure why
DD-WRT> ip_address -l 192.168.1.254/24 -h 192.168.1.10
Reset the IP and tried to use the TFTP client to load linux.bin back into the home dir. Worked, so the server was up.
So try yet again…following the flash instructions, but starting after the :

Router starts up. I get a website at http://192.168.1.1:8080/
Yippee!
