A one-button set-up for secure wireless LANs will finally hit the market next week, more than three months later than its scheduled release.

The SecureEasySetup (SES) technology developed by Linksys and Broadcom is designed to make it easier for consumers to set up wireless LANs with WPA (Wi-Fi Protected Access). SES consists of firmware for routers and access points, as well as a software utility for devices such as PC Card adapters.

Users will be able to set up a WPA wireless LAN by simply clicking a software button in the setup utility and pressing a physical button that has been built in to routers and access points since earlier this year in preparation for SES, said Mani Dhillon, senior manager of product marketing at Linksys. Previously, users had to manually set up and enter an SSID (Service Set Identifier) and an encryption key and write them down for safekeeping, a series of steps that many customers found too hard, Dhillon said.

Lack of security has dogged consumer wireless LANs, partly because many users never even set up the systems that come with the gear. Last month, a man was arrested in Florida on charges that he parked outside a home with an unsecured wireless LAN and used it to take advantage of the resident's high-speed Internet connection.

Linksys worked on SES with Broadcom, which supplies the chips in Linksys's wireless routers but not in its client adapters. It was announced in January at the International Consumer Electronics Show, at which time a Broadcom executive said Linksys was expected to put the technology onto its devices in the first quarter. Broadcom's projection was overly aggressive, maybe because the company didn't know all the steps involved in the introduction, Dhillon said. Linksys had to make SecureEasySetup work on non-Broadcom devices, provide firmware for older products and wait for retail stores to sell out of devices that were made before the hardware button was built in, he said.

The technology is now shipping with all of Linksys's Wireless-G and SpeedBooster routers and adapters, and the company is offering firmware upgrades for routers and access points dating back about two years, Dhillon said. Users of routers that shipped with the hardware button can now download new firmware and use the button, and with other routers a software button can be added to the device's software interface, he said. Within the next few weeks, Linksys will ship a Wireless-G Access Point with SecureEasySetup, according to the company.

Linksys also is providing software for HP notebook PCs that have built-in Wi-Fi adapters, and it will also offer the software for an HP Wi-Fi printer that is expected to ship by the end of this year, Dhillon said. The company is seeking similar arrangements with other PC makers, he added.

WPA is an improvement on the original WEP (Wired Equivalent Privacy) protocol that shipped with early Wi-Fi gear. Linksys has started to roll out the latest security technology, WPA2, across its router line, Dhillon said. Routers equipped for WPA2 are backward compatible with WPA, and WPA products can be upgraded through a firmware download, he explained.
