Hardware Configuration

It was easy to open the case but hard to check out the hardware configuration visually because almost all of the chips are covered with aluminum heatsinks which are soldered to the PCB. So, we had to resort to software-based methods of identification. There’s a console among the unlabeled connectors on the PCB but it’s easier to access the router via the well-known telnetenable utility which works on the WNDR4500 as well.

So, the router is based on a Broadcom chipset. The main processor BCM4706 has a clock rate of 600 MHz. It is accompanied with 128 megabytes of both system and flash memory. A USB controller is integrated into the processor, providing two USB ports. The Gigabit Ethernet switch is Broadcom’s BCM53115. The router doesn’t support Jumbo Frames but, hopefully, this deficiency will be corrected with firmware updates. The wireless interfaces are implemented by means of two BCM4331 chips, one for each frequency band. Each chip supports the fastest operating mode possible – 3T3R (450 Mbps).

Although the WNDR4500 is larger than its predecessors, the compact antennas are detachable. There are three antennas for each frequency band. The 5GHz ones are at the top of the case and the 2.4GHz antennas are placed apart from each other.
