OpenWrt for the Buffalo WBMR-HP-G300H comes with the ADSL annex B firmware pre-installed.

To install the more commonly used annex A (PSTN) firmware, proceed as follows:

1. First remove the annex B firmware:

opkg remove kmod-ltq-adsl-ar9-fw-b

2. Download the annex A firmware from OpenWrt.

3. Copy the firmware to the modem. On Windows you can use PuTTY’s pscp. On Linux you can use scp. Here I’m using pscp at a DOS prompt to copy kmod-ltq-adsl-ar9-fw-a_0.1-1_lantiq.ipk to 192.168.1.1 as fw.ipk.

>pscp -scp kmod-ltq-adsl-ar9-fw-a_0.1-1_lantiq.ipk root@192.168.1.1:fw.ipk
root@192.168.1.1's password:
kmod-ltq-adsl-ar9-fw-a_0. | 187 kB | 187.5 kB/s | ETA: 00:00:00 | 100%
>

The package will be copied to the root user’s home folder as fw.ipk:

root@OpenWrt:~# ls
fw.ipk
root@OpenWrt:~#

If you’re using scp on Linux, the command is similar: scp kmod-ltq-adsl-ar9-fw-a_0.1-1_lantiq.ipk root@192.168.1.1:fw.ipk .

4. Install the firmware:

root@OpenWrt:~# opkg install fw.ipk
Installing kmod-ltq-adsl-ar9-fw-a (0.1-1) to root...
Configuring kmod-ltq-adsl-ar9-fw-a.
root@OpenWrt:~#

… and you are done!
