TrustedReviews have looked at the Asus WL-700gE NAS Appliance which combines a router, an integrated four-port Fast Ethernet switch, SPI firewall, wireless access point, web, media and FTP servers, a message board and even facilities for networking USB webcams and adding motion detection. Here's a bit:

Basic network shares are easy enough to create and access can be allowed for Windows, Unix and Linux clients as well as over FTP and HTTP. Access restrictions can be applied to selected shares with a local user database and the appliance can become a member of an NT authentication domain. In keeping with most small NAS appliances the WL-700gE functions as an iTunes server. There's nothing to do here except activate this service whereupon a default folder is created for storing your tracks. Open the iTunes client and the appliance automatically appears in the source list.

The wireless access point offers both WEP and WPA encryption and supports Asus' BroadRange technology. Previous tests run on the Asus WL-550gE returned modest results that never went above 30Mb/sec although we did observe BroadRange having an impact at greater distances with speeds only dropping to a low of 26.5Mb/sec. If you slot a USB storage device in the front port and press the Copy button on the front panel then all the contents of the device will be automatically copied to a predefined folder on the appliance. We successfully tested this with a 512MB Buffalo FireStix and watched the appliance copy 383MB of data in less than two minutes.
