Wireless Networks, is it secure?
There are a few different setup scenarios for wireless networks, depending on whether you're using a hub or a wired router.

Wireless kits are adopting a uniform standard, much the same way cell phones do. The emerging standard appears to be a contest between "WiFi" and "Bluetooth." My research reveals that WiFi supports higher speeds, longer range, and even interfaces with Mac's and PCs.
Is wireless networking secure? It most definately can be. There are multiple layers of security that aren't to difficult to implement that can almost assure secure wireless networking. The most well known form of security for wireless if WEP encryption.
However, there is a weakness in WEP that allows a hacker to break the WEP key and gain access to your network. Once you've connected your first wireless computer and have verified that the connection is working, your next concern is security. After all, your precious data is floating through the air, where it can be intercepted by anyone with a wireless network card and your WLAN service area number. Fortunately, the Air Connect hub supports encryption.
Of course if you've already mounted your hub on the ceiling or another difficult-to-reach location, it might be hard to attach a serial cable to configure the hub's security. Fortunately, there's an easier way. It is important to assign a password to the wireless hub. You should do so because most hub contains a built-in Web server. Simply enter the hub's IP address in any Web browser, and you can access the hub's Web server. You can then make any necessary security modifications without having to use a serial cable. Once you've enabled encryption, you're ready to start adding more computers to your wireless network. Most wireless hub can support up to 63 computers. I've heard that as you approach the client limit, communications can slow down. However, I've run up to three clients off my hub and never experienced a slowdown. You may wonder what happens if you wander out of range while connected through a wireless session. Believe it or not, you don't have to worry about doing so, even if your building is too large to be completely serviced by a wireless hub. That's because wireless network cards work similarly to cellular phones: If they sense that the signal is getting weak, they will search for a stronger signal. Therefore, it's possible to install multiple wireless hubs. As your wireless users stroll through the building , their computers can engage in active roaming as they switch from hub to hub. As you can see, setting up a wireless network is a fairly simple process. Wireless internet sharing is a huge benefit to any network. Lots of companies are abandoning dial up modem access in favor of virtual private networks (VPN's) that allow you to access all of your company's network, intranet, and email, all via the Internet. The faster your connection, the more productive you are.
The backbone of any proper office is a properly installed network. You need all the access that your office provides, and that means that all your equipment needs to talk to each other. Setting up a wireless environment takes time, a bit of money, and more than a fair share of patience. It's well worth the effort.
