Back to the router, and general security is provided by a standard SPI firewall which is switched on by default and you can also choose to block proxy servers, ActiveX controls, Java applets and cookies. We noticed that Linksys' DHCP server still defaults to only reserving client IP addresses for a single day and we would recommend activating the option that reserves IP addresses for specific MAC addresses when they are first dished out. This way any systems that rely on having the same IP address assigned such as those in the DMZ or included in port forwarding rules won't have any problems.
The router provides a useful range of access controls and you can use up to ten policies for restricting Internet access where each one can contain a schedule, a list of PCs defined by their MAC or IP address and a URL or keyword list. The latter two features are of limited value as you can only add four URLs and four keywords to each policy. However, you can use each policy to block up to three applications where you select a service and port range or add your own custom applications. QoS (quality of service) is also on the menu and traffic priorities can be applied to applications, voice devices, individual MAC addresses and even a specific Ethernet port.
Wireless security features look good, too, as you can activate SSID masking, MAC address filter lists and WEP or WPA/WPA2 encryption. You have WPA Personal and Enterprise with the latter requiring an external RADIUS server for user authentication. We found wireless performance to be very respectable and to test this we installed a Linksys RangePlus WUSB100 USB adapter in a Windows Vista test system. Copying a 690 MB video clip between this system and another on the LAN over a close range WPA encrypted link delivered average speeds of 50Mbit/sec - almost as good as many wireless-N products.
Linksys' WRT110A is a low cost wireless-G router that offers a reasonable range of features for the price and surprisingly good wireless performance, but is let down by the ultimately flawed LELA utility.
