Edimax is one of those Taiwanese hardware companies that makes a bewildering array of networking products. Admittedly, many models are only slightly differentiated from their neighbours, but the odds are that Edimax makes something that precisely matches your needs.
At first glance, this is a fairly standard 802.11g wireless router, with the usual four fast ethernet switched ports in a neat enclosure. It's a router so it probably works best in conjunction with a cable broadband connection, although you can make it work with an existing ADSL router. Setup is fairly easy, but the Quick Setup wizard could be more helpful.
As a router this is no-frills, which manifests itself in things such as low-quality documentation, the odd typo, slightly awkward phrasing on the web interface, the absence of Help and the poorly located status LEDs. Although graced with 14 LEDs, unless you view them ‘on-axis' they're hard to make out. Plus any configuration change requires a tedious 60-second reboot.
But what sets the BR-6215SRg apart from the common herd is its support for NAS (network attached storage). A pair of USB 2.0 ports let you plug in an external hard disk or two, and these can then be shared with other PCs attached to the network. This works either with simple peer-to-peer or client/server networks. And it supports multiple sharing methods.
Or you can plug a printer or two in to the USB ports - there's a print server in there too, thus letting you connect wirelessly to a printer. Supported protocols include LPR, IPP, SMB/TCP, Raw Printing and Unix Logical printing. You can even access the print server from across the internet. The final bonus is support for Quality of Service traffic prioritisation.
