Inside a 3Com 3CRWDR100A-72 Wireless ADSL Router

We take apart our new 3Com ADSL Wireless 11g Firewall Router to see what makes it tick. This is the same router that comes in 3Com's 3CRWE754G72-AGBUN router/pcmcia-card bundle.

In a pleasant change from most wireless kit we've looked at, there were no Warranty Void If Broken stickers on the kit, so taking the cover off was just a case of gently prising off the 5 small clips that hold the plastic top onto the metal base plate.

The back panel has everything as expected (from left to right) adsl telephone socket, power socket, reset button, power button and 4 ethernet ports

As with most wireless routers, the actual wireless hardware is provided by a small daughter board, usually either a PCMCIA card, or a mini-PCI card, as appears to be the case this time. Both antenna are connected to the small wireless card, and are also seperately earthed to the main board below.

Turning the main board over, there appear to be no extra chips on the underside as we occassionally find

Finally turning to the antenna, they are not detachable so no RP-SMA connectors here.
