Compared to ICS
Rather than purchase a Linksys router or comparable hardware device, some people choose to implement Microsoft's Internet Connection Sharing (ICS). Like the Linksys, ICS allows multiple computers to share a Net connection by using Ethernet cabling and network adapters. But ICS does not require a router on the network; instead, it designates one of the local computers as the host device.

In its role as a host, the host computer must serve two functions: it must connect upstream to the DSL or cable modem and downstream to the internal LAN. Computers acting as these gateway devices must be installed with two network adapters (one for upstream and one for downstream connectivity). They must be connected to the Net and remain "on" for other clients on the LAN to have Net access.
ICS appears compelling at first because it offers connection sharing without the use of dedicated hardware (the host computer can also be used as a client). ICS works especially well with a two-computer network. However, on an ICS LAN with more than two computers, a hub or equivalent device will be required to interface all of the clients to the one host. Finally, firewall software will typically be needed on such a network to provide a reasonable level of security.
The Linksys router combines the functions of the multi-homed (dual NIC) gateway, hub, and firewall software into a single unit. It does not require clients to run the Windows operating system as ICS does.
Compared to Netgear RT314
Linksys routers have direct competition in the market today from the Netgear RT314. Technically, both Linksys and Netgear products offer similar features at roughly the same price. Choosing between a Linksys and a Netgear essentially boils down to non-networking factors such as:
- look-and-feel of the hardware (the two vendors differ most significantly in their styling and materials)
- perception of the vendor's technical expertise and quality of support
- family and friends' past experience with the products
Conclusion
Linksys routers hide some of the complexity of computer networking from their users while offering a blend of useful features. Alternative approaches to Net connection sharing and security may not necessarily be less expensive or more robust. Customers have generally been very pleased with this product's ease of use, reliability, documentation, and overall ability to deliver on its promises.
