The LINKSYS WRT54G/GS routers are quite popular and offer the ability to upload your own firmware. With the right firmware you can monitor the router using SNMP.
In order to monitor a LinkSys WRT54G/GS router with PRTG via SNMP you must enable SNMP on the device. If your firmware does not support SNMP already you need to upload another one (e.g. the Open-Source WiFi-BOX firmware for the WRTG54G offer SNMP for this device). Remember to set the SNMP "public" string which will serve as a password. Then open PRTG, click "Add Sensor" and point the IP to your router. You will see a number of interfaces:
- vlan0: All wired ports (4 LAN ports)
- vlan1: The WAN interface (which connects to the Internet)
- br0: Totals of the whole network switch (vlan0 + eth1)
- ppp0: The PPPoE interface (if enabled)
- eth1: The wireless interface
- eth0: The hardware device the VLAN's are created from.
(This may depend on your device and firmware version. More details here) Select the one you want to monitor and that's it.
You there!
