- Observations on the Message Integrity Code in IEEE802.11 Wireless LANs
- This paper surveys the security of the message integrity code used in the IEEE802.11 Wireless LANs. To address the security flaws of Wired Equivalent Privacy WEP, the IEEE802.11i draft defines two data confidentiality and integrity protocols, Temporal Key Integrity Protocol TKIP and Counter-Mode-CBC-MAC Protocol CCMP.

- Linksys WRT310N Wireless-N Gigabit Router
- The Linksys WRT310N Wireless-N Gigabit Router is basically the Draft N 2.0 version of the RangePlus WRT110 that we reviewed earlier this month. Bearing the same sleek, antenna-free design as the WRT110, the WRT310N offers two significant upgrades: Gigabit networking and Draft N 2.0 compliance. We are a little disappointed...

- Linksys WRT110 RangePlus Wireless Router
- The Linksys RangePlus Wireless WRT110 is not a Draft N router, but Linksys doesn't call it a Wireless-G router, either. The reason? It works with both specifications. It supports the 802.11g standard, but the company's RangePlus technology takes advantage of the throughput threshold of the draft 802.11n specification and offers...

- LevelOne NetCon WBR-6000 N-One
- The first router we've reviewed from LevelOne, the N-One WBR-6000, made a good first impression with its styling and easy setup, but its poor performance ultimately left us disappointed. Unless a funky design and low cost--the WBR-6000 can be found online for roughly $90--are more important to you than speedy...

- Nikon Coolpix S51c (Silver)
- Why mess with a good thing? That seems to be Nikon's approach to its Wi-Fi-enabled ultracompact cameras. When they came out with the Coolpix S50c last year, I noticed that it was extremely similar to its predecessor, the S7c. Now, Nikon has made the Coolpix S51c, which is nearly identical...
