The Linksys WAG354G is an ADSL gateway with wireless acccess point integrated.

Platform: TI AR7WRD

SoC: TNETD7300AGDW

Processor: MIPS 4KEc V4.8 @ 150 MHz

4 port switch: Infineon ADM6996L

Wireless chipset: TI TNETW1130

Expansions: VLYNQ slot for wireless card

Internal: Big size

The unit comes with an internal antenna. It's possible to add an external antenna via the R-SMA plug. There seems to be a mechanical switch that gets (de-)activated when you open the tap of the external antenna port.

• Serial console

Serial console can be plugged to JP5: connector lacks, it has to be soldered on the board. -My board actually has the header already installed on JP5. – RobertSiemer 21Z)

You cannot plug directly those pins to your pc serial port. You need a RS232-TTL level adapter.

See Serial_Console

Terminal

Configuration:

 38400 bauds, 8 bits, no parity, 1 stop bit (38400 8N1)

Jtag pins are located in JP2, but the connector lacks. The pinout and specifications are the same of others AR7 devices that is 14 ping ejtag 2.6.

With the router upside down, GND pins are located in the upper pin strip.

You can use Hairydairymaid Debrick Utility with a Xilinx cable.

One gpio for the reset button. One gpio for switching between internal/external antenna.

to be written (& tested)…

-I think that apart from having a "external antenna tap open" detector, the wireless card should have a mode to use both antennas at the same time. (Maybe not, but most cards I know which have two connectors can do so.)

• Mods

Possible mods:

• The VLYNQ expansion card is not interchangeable with a mini PCI card, despite sharing form factor

• Add an SD card reader.

(Add an SD card where!?)

The latest openwrt kamikaze has more recent ADSL drivers with support of ADSL2+, and a preliminary support for the wireless card, using the open soure drivers by the ACX100 project .

Checkout the latest kamikaze trunk:

svn co https://svn.openwrt.org/openwrt/trunk/

As trunk is always changing it may happen something will not work as expected, both in compilation or use of the firmware.

Now you have to set up the configuration entering

make menuconfig

Choose as target platform AR7. Then in kernel configuration select [*] the Annex that matches your router.

The following configuration applies only to OpenWRT Kamikaze with 2.6 kernel version.

NOTE: All the network interfaces can be configured via the /etc/config/network file. File structure is self-explicative, here I will just show you some examples.

ppp0 (adsl) interface

• PPPoA + VC

config interface wan
        option ifname   atm0
        option proto    pppoa
        option encaps   vc
        option vpi      8
        option vci      35
	option username "yourusername"
        option password "yourpassword"     

For this work you can both consider eth0 and wlan0 as 2 separate interfaces, or bridge them. I have choosen the first way.

• The wireless chipset needs a firmware. You can download some firmwares for the ACX111 chipset here. Choose one firmware binary (I used the last version) named tiacx111c16 and upload it in the /lib/firmware/ folder of your router.
• Edit the /etc/config/network file according to the section above.
• Reboot your router. At this point wireless drivers should have been started in a sort of client mode. Just fyi, this is the output of console:

acx_i_timer: adev->status=1 (SCANNING)
continuing scan (1 sec)
acx_i_timer: adev->status=1 (SCANNING)
continuing scan (2 sec)
scan table: SSID="trainstation" CH=1 SIR=44 SNR=0
peer_cap 0x0511, needed_cap 0x0001
ESSID doesn't match! ('trainstation' station, 'STA1D2AE8' config)
no matching station found in range yet                               

Enteringifconfig wlan0 you should see an output according to your configuration.

• Use iwconfig to configure the the wireless properties.

Some examples

iwconfig wlan0 mode Master essid openwrt channel 6 txpower 15

This will create an open netword with ssid "openwrt", using channel 6 and with transmission power set to 15. Transmission power range is 10-15dbm.

iwconfig wlan0 mode Master essid openwrt key restricted 1234AAAABB channel 6 txpower 15

Like the previous, but this time the network is protected with WEP (whoa!) with the hex key 1234AAAABB. If you use a shorter key, it will be fullfilled with zero to reach the 10 symbols. Refer to themanualfor all the options. I observed that if I enter "ifdown wlan; iwconfig….;ifup wan" the router crashes. So dont enter ifdown before entering iwconfig.

• Configure the natting. With the following script packets from wlan0 are sent to ppp0, that is Internet connection. Change EXTIF to eth0 if internet is reachable from the ethernet.

#!/bin/sh
INTIF=wlan0
LANIN=192.168.100.0/24
EXTIF=ppp0
iptables -A INPUT -i $INTIF -s $LANIN -j ACCEPT
iptables -A OUTPUT -o $INTIF -d $LANIN -j ACCEPT
iptables -A FORWARD -s $LANIN -d 0/0 -j ACCEPT
iptables -A FORWARD -m state --state ESTABLISHED,RELATED -d $LANIN -j ACCEPT
iptables -t nat -A POSTROUTING -o $EXTIF -s $LANIN -j MASQUERADE
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A OUTPUT -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT

• Check the routing table using "route". If the default rule is wrong, delete it

route del default

and enter the default for right one for your configuration. In this case:

route add default ppp0

• If you want the dhcp server on the wlan0 interface:

dnsmasq -i wlan0 --dhcp-range=192.168.100.50,192.168.100.150,12h

WARNING This page is a work in progress. So far I (IanJackson) am just collecting information found in various other places (eg, IRC logs) together.

Known problems:

* `Crashes occasionally' for some people or with some devices. Currently not known whether this is a hardware problem.

* Using the tftp procedure to upload an openwrt image seems for some people to disable the tftp facility in PSPBoot, so that future upgrades have to be done from within openwrt. However this didn't happen to me -IanJackson.

Same as the V1.
