RegHardware takes a look at the Asus WL-530g compact wireless router:

There are four LAN ports on the back of the router alongside the power port and antenna hook-up, and a WAN port on the right-hand side. There are three LEDs that indicate power, wireless LAN activity and Ethernet activity. Finally, there's a small reset button. I like the fact that Asus has put the default admin login details on a sticker on the bottom of the router.

The antenna is small and consequently the reach of the wireless link isn't as good as some other routers. Asus quotes a line-of-sight range of a mere 60m (197ft) outdoors, while indoors you won't realistically get more than about 25m (82ft). The WL-530g supports a wide range of configuration options for both the WAN, LAN and wireless sides, although for novice users it has a fairly simple-to-use set-up wizard. The user interface isn't the most intuitive one I've used, but it's far from the worst.

You get basic features such as a DHCP server, NAT, UPnP, VPN pass-through and an SPI firewall, as well as WEP and WPA encryption, and MAC address filtering to control who gets to use the wireless link. It also offers a range of more advanced set-up options for those that like to have a play. Interestingly, Asus also offer the router's firmware under a GPL licence, so if there's something you're not happy with, you can download the source code from Asus' website and change it yourself.
