It's common knowledge that WEP can be "easily" cracked. But did you ever wonder how easy it is? In Part 1 of a two-part series, Humphrey Cheung takes you step-by-step through putting together a WEP-cracking setup and using Kismet to find vulnerable wireless LANs.
In late 2005, I moved into a new home and had to establish new test locations. Since this essentially wiped the slate clean in terms of being able to compare wireless test results going forward to those from my previous reviews, I also decided to establish new test methodology and add a scoring system.
The nice thing about wireless LANs is that you don't have to be physically connected to use them. But that strength also opens the door to security problems. Derek Boiko-Weyrauch shows you how a popular open source tool can be used to keep tabs on WLAN activity.
There are those who think Bluetooth is secure due to its intentionally-limited range. But Part 1 of this article by Humphrey Cheung shows you how a little time and not a lot of money can produce a weapon that can blow away any such thoughts.
Today's notebooks all come with the ability to host an internal wireless LAN card. But cost-sensitive buyers may choose to forego that option and later regret it. But as long as you're willing to do some homework, our How To shows that it's not that hard to add a WLAN card yourself.
The freedom of wireless networking is now a reality for everybody with a suitably equipped device. At one time too expensive for everything other than corporate use on a business network, Wi-Fi is now mainstream. In many respects, this is due to Intel's extensive marketing of its Centrino brand, launched in mid-March 2003.
Linksys' WRE54G Wireless-G Range Expander [reviewed here] is a WDS-based 802.11b / g repeater that Linksys says works only with its WAP54G access point and WRT54G and WRT54GS wireless routers. But with a little effort, you can get it to function with any 802.11b or g product that supports WDS-based bridging and/or repeating.
Here's the problem. You're cheap...uh, make that frugal... have one or two wireless laptops that you want to get connected to your LAN, and don't want to buy an access point or wireless router to do it. Can it be done?
Probably the most frequently asked question about wireless LANs is how to improve their performance. Although the focus is usually on improving range, what people many times want is to get a better (or any!) wireless connection from a specific location in their home or small office.
D-Link's 2.20 firmware update for its DWL-900AP+ Access Point has finally brought wireless repeating to the masses! What used to cost about $500 can now be had for about $100!
