If your problem is the wireless range of your laptop or desktop then read this and follow the steps below.

Wireless networking at 2.4 GHz is a two way system. Each device must be capable of both sending and receiving a signal equal distances. Access points and wireless routers (as shipped from the manufacturer) have an advantage over laptop and desktop cards because they have a higher output power and therefore have the ability to send a signal further then most laptop and desktop cards. When a higher gain antenna is installed on a desktop card that devices output power is now increased closer to the output level of the access point or wireless router therefore equaling the two devices. In some cases both the access point/wireless router and the desktop/laptop card antenna's may need to be replaced. This is if the distance you are attempting to achieve is greater than the distance the access point/wireless router is capable of when using the antenna's that came with your card.

Building to Building Connections: When connecting two or more building's it is best to first establish a wireless bridge between the building's first. This is achieved by installing a wireless bridge. Then if you need to be wireless within a building then attempt to establish a wireless network within each building. Desktop/Laptop/ and other client devices will not work correctly if the access point/wireless router is not resident in the building where the access point/wireless router is located. You should consider step 4 for this application.

Step 1: Desktop Fix: Replace the antenna on your desktop card with the HD19654

Step 2: Laptop Fix: Most laptop cards have very poor receive sensitivity and therefore have very limited range. Replace your laptop card with a better card and consider additional antennas for these cards if your range is greater than 75-100 feet.

Step 3: Access Point/ Wireless Router Fix : The above will increase the range of the laptop and desktop now if you wish to increase the range of the access point/wireless router than select an antenna bundle below that best fits your situation.

Step 4: Connecting two or more buildings Fix : If you wish to connect two or more buildings together than select an wireless bridge bundle by clicking here.
