In this guide, I'll discuss how to add traffic monitoring called WRTbwlog on to your WRT54G. It's quite simple, and once done, will keep track of all downloading and uploading on your router. It is not like SNMP monitoring where you need a PC running to record the data. However, your logs will be lost during every reboot, unless you back them up into a partition in Talisman for example. You can also add this to your rc_startup so it will start when you start your router. For help on either of those, please consult our forum.
Steps to add WRTbwlog
Latest Version: 1.1

1) First, make sure Telnet is "Enabled" on your router. You can not do this on the default Linksys firmware. The Telnet option is in the Management page of your router.

2) With Telent enabled, open up HyperTerminal or another program to Telnet into the router. Remember, the IP of your router is 192.168.1.1.

3) Now login to your router, for a login, use root, and then enter your router password.

4) Once you successfully login, you should see something like this.

5) Now, you'll know to type in a few things. Enter one line at a time, pressing Enter after each. Wait for each to complete before typing the next line.

cd /tmp
wget http://wrt54g.hetos.de/wrtbwlog.tgz
tar -xzf wrtbwlog.tgz
cd bwlog
./start.sh

6) Unless you typed something wrong, the program should be up and running. You'll know have several pages of information. First is http://192.168.1.1:8000/traffic.cgi. Which includes all of the traffic information. Second is http://192.168.1.1:8000/status.cgi. Which includes status and hardware information like memory usage, CPU usage, running processes, network interfaces, routing table, arp table and wireless connections. Third is http://192.168.1.1:8000/wlanlog.cgi, which includes an optional wireless client monitoring script. Watch memory usage over long periods of time. Last is http://192.168.1.1:8000/wlanscan.cgi, which provides a frequency analaysis of the WLAN 2.4Ghz frequency. This can tell you about outside frequency pollution. This will take several minutes to complete, WLAN will be down during this time.
Thanks to hetos.de for making the program!
