Linksys routers

Linksys manufactures a series of network routers. Many models are shipped with Linux-based firmware and can run third-party firmware. The first model to support third-party firmware was the very popular Linksys WRT54G series.
The Linksys WRT160N/WRT310N series is the successor to the WRT54G series of routers from Linksys. The main difference is the draft 802.11n wireless interface, providing a maximum speed of 270 Mbit/s over the wireless network when used with other 802.11n devices.

Specifications and versions

BEFW11S4

Linksys' first series of wireless routers.
The Linksys BEFW11S4 is a Wi-Fi capable residential gateway from Linksys. The device is capable of sharing Internet connections among several computers via 802.3 Ethernet and 802.11b wireless data links. With only 1 MB of flash storage and 4 MB of RAM, no third party replacement firmware is compatible with it.

WRT54G series

The Linksys WRT54G and variants WRT54GS, WRT54GL, and WRTSL54GS are Wi-Fi capable residential gateways from Linksys. The device is capable of sharing Internet connections among several computers via 802.3 Ethernet and 802.11b/g wireless data links.
The WRT54GL as well as most of the other variants in this series, are capable of running Linux-based third-party firmware for added features. Supported software includes Tomato, OpenWrt, and DD-WRT

E4200

A three-stream simultaneous dual-band gigabit model targeted for "high performance wireless entertainment", with a rated maximum throughput of 450 Mbit/s. This model also includes a USB port for storage, UPnP media streaming or a print server.
The E4200 also marks the first radical change in the design of the Linksys series since Cisco launched the winged "spaceship" design first seen on the WRT400N. The E4200 features a minimalistic, streamlined design with only a white status LED visible on the top. All traffic activity LEDs and buttons have been relocated to the rear of the device.
A special system menu can be accessed by browsing to http://ip_address_of_e4200/System.asp. This menu shows all kinds of system statistics and settings. No settings can be changed from this menu. This is only found in the original version, and not available in the v2 model.
The E4200V2 has a Marvell 88W8366/88W8063 wireless chipset.
In previous Tomato builds, only the 2.4 GHz radio was properly supported. However, simultaneous dual-band radio can now be achieved using Tomato RAF, Tomato Shibby and Tomato Toastman's builds.
