TPLINK C2600

NOTE: Currently broken on the latest upstream Openwrt reference: 87b14bc6c289e7e80052b344c0f0c35e95ced267 Will be fixing as soon as possible but not in time for SCaLE 18x

Configuration

Currently the default configuration for network and wireless need to be applied

Flashing

The following is needed to flash the c2600:

  • TFTP server
  • Static IP address 192.168.0.66

Linux

Assuming you are on raspbian

Setup the interface for the expected IP (`eth0 in this case):

auto eth0
iface eth0 inet static
	address 192.168.0.66/24

Reboot the host to set the new interface up

nstall following packages.

sudo apt-get install xinetd tftpd tftp tcpdump

Create /etc/xinetd.d/tftp and put this entry

service tftp
{
protocol        = udp
port            = 69
socket_type     = dgram
wait            = yes
user            = nobody
server          = /usr/sbin/in.tftpd
server_args     = /tftpboot
disable         = no
}

Create a folder /tftpboot this should match whatever you gave in server_args. mostly it will be tftpboot

sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot

Restart the xinetd service.

newer systems:

sudo service xinetd restart

FreeBSD

Currently this is how a flash the routers

Setup the interface for the correct static IP (ue0 in this case):

ifconfig ue0 inet 192.168.0.66 netmask 255.255.255.0

Configure the tftpd daemon in inetd:

cat << EOF >> /etc/inetd.conf
tftp   dgram   udp     wait    nobody  /usr/libexec/tftpd      tftpd /tftpboot
EOF
service inetd onestart

Add the necessary files to /tftpboot/:

cp <image>-squashfs-factory.bin /tftpboot/
ln -s <image>-squashfs-factory.bin ArcherC2600_1.0_tp_recovery.bin

NOTE: This has to be called ArcherC2600_1.0_tp_recovery.bin since tftp client from AP only looks for that name

Setup tcpdump to watch for traffic on the interface being connected to AP:

tcpdump -i ue0 -n udp port 69 -X

NOTE: Keep this running in a separate window as you'll see the image be pulled on a successful flash

On the AP:

  • Connect ethernet to any LAN port on AP
  • While holding down reset, power on device and keep reset pressed for 15 sec
  • Check tcpdump for activity, a successful flash take about 5 min to apply. Top power symbol light will flash signalling successful apply

After a successful flash, reconfigure the interface for dhcp or static depending on your needs:

ifconfig ue0 delete
ifconfig ue0 down
ifconfig ue0 inet 192.168.254.1 netmask 255.255.255.0
ifconfig ue0 up

Setup dhcp server:

sudo apt-get install isc-dhcp-server
