Comtrend CT 536+ / HG 536+ is based on a Broadcom proccessor (board ID 96348GW-11).
|SoC||CPU speed||Ram||Flash||Network||DSL port||USB||Serial||JTag||Buttons|

As reported in the Attitude adjustment announcement, for 16MiB of RAM devices you should better stay with Backfire (linux 2.6.32), or you will experience contention problems due to an often lack of free memory.
The OpenWrt correct firmware is openwrt-96348GW-generic-squashfs-cfe.bin, which can be directly flashed from the original firmware page.
Notice that ''Backfire'' does not implement the failsafe boot with the reset button yet, for this router. Failsafe can be triggered only through the serial line.
A usual procedure to flash with OpenWrt using the factory CFE bootloader:
This procedure will not overwrite the CFE bootloader, so you can use it later to reflash the router with any other firmware.
NOTE: Onboard DSL modem is NOT SUPPORTED
However you can connect an external modem bridged to a LAN port.
All required packages are already installed in the default image.To configure PPPoE with UCI, do this:
uci set network.wan.proto=pppoe uci set network.wan.username= uci set network.wan.password= uci commit network && ifup wan
Note: if you need QoS for consistent low latency on an ADSL connection, which is a common scenario, you should consider installing the
dsl-qos-queue package instead. It works much better than the Linux QoS because it does factor in the ATM overhead, which can be significant.
Install the qos-scripts package:
opkg install qos-scripts
Basic QoS configuration using UCI:
uci set qos.wan.upload=192 # Upload speed in KB uci set qos.wan.download=2048 # Download speed in KB uci commit qos
Start QoS and enable on next boot
/etc/init.d/qos start /etc/init.d/qos enable

To open the case remove the two rubber feet on the opposite site to the antenna jack, they will reveal two crosspoint screws.
