Besides the main PCB, the router has a wireless module on a separate daughter card. It is plugged into the mini-PCI slot located near the router’s processor.
The Wi-Fi module consists of three controllers with accompanying components. The TNETW1130 WLAN processor from Texas Instruments is the main one.
It supports modern WLAN standards (802.11b and 802.11g) and QoS mechanisms.
An RC2422 transceiver is connected to the WLAN processor. It was designed specially for devices that support both 802.11b and 802.11g.
The chip carries the logo of RADIA Communications that was devoured by Texas Instruments in 2003.
The RFFE controller is branded by RADIA, too. This chip is called RC2326.
It is recommended by the manufacturer for use with the RC2422.
And finally, the router’s antennas are connected to the RC2326. The internal antenna is not wired, as is often the case, on the PCB, but is designed separately and is attached to the Wi-Fi module with a screened cable.
The external antenna’s connector is attached in the same way.
The router’s PCB also has a seat for a console connector which is missing on our sample of the device:
