exact item shown - I was using it with a wireless-G access point (which I have also just listed) - you remove the antennas from the access point and attach them to this booster, the booster sits on top of the access point.
If you get the booster and the access point, remember to ask me for an invoice so I can combine shipping.
the data sheet is here:http: <slash slash> downloads.linksys <dot> com/downloads/datasheet/wsb24_ds.pdf (sorry you have to fix the link, no longer allows this kind of useful information in links if the link is live) I\'ve quoted some of the info below, please look at that data sheet for instructions and more info.
Turn up the volume on your Wireless LAN! The Linksys Wireless Signal Booster piggybacks onto your Linksys Wireless Access Point (or Wireless Access Point Router) to increase the effective range and coverage area of the 802.11b network. The added signal strength also helps speed up your close-range communications, because every packet comes through “loud and clear”, reducing retransmissions due to reception errors.
To install, just stack the Wireless Signal Booster on your Access Point, move the antennas to the Booster, and attach the Booster\'s twin cables to the Access Point—no drivers or modifications to your setup are necessary.
The Linksys Wireless Signal Booster saves wiring costs and helps to build corporate wireless infrastructure by driving signals even into those distant, reflective corners and hard-to-reach areas. And it’s perfect for covering large areas in warehouse environments, public spaces, wireless hotspots, and outdoor venues—anywhere you need extra coverage for your wireless LAN

I normally ship within 24hours of your order, but the post office does not alwaysinitiate tracking when Iput the packages in the drop off box. So I have set the handling time to 3 days so will stop penalizing me for late shipping.
