Comtrend CT 536+ / HG 536+ is based on a Broadcom proccessor (board ID 96348GW-11). Openwrt correct firmware is openwrt-96348GW-generic-squashfs-cfe.bin, which can be directly flashed from the original firmware page.

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.

1. you could read about bootloader in general

1. as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!

It has to be soldered. See: Photo Link
