afaik there's two type of airlink router sold on outpost, first is the 54 g (AR315W), this router is bad, stay away from it unless you are trying to play with it, some said the problem might be caused by overheating. The second is the atheros super g 108 mbps (ar410w) version, this router is said to be the oem version of dlink DL-624 (also super g version) because of similarities from led position, antenna, and also webadmin interfaces, but also with some features added, some features removed.
Unfortunately many DL-624 seems to have problems with the router keeps rebooting, probably because channel interference, some users also report the lan switch will go wear out after usage, there's some people claim after months, the switch would not recognize the lan except the lan card is set to half duplex 10 mbps, i don't now whether this is the same for airlink router. Try looking dslreports.com for some review from the owner there, both for dlink dl-624 and airlink router.
