You love your laptop, but maybe its WiFi network adapter is on the fritz or you"re stuck with an old and slow Wireless G or B card. You could try to get it upgraded or repaired, maybe even plunk down at least a few hundred bucks for a new computer, but there"s an easy, inexpensive option that will get you back on the network in no time: Use a USB based WiFi adapter! The Plugable USB-WIFINT wireless N adapter when plugged into a USB slot sticks out just a quarter of an inch. Our new nano WiFi adapter offers 802.11n wireless N connectivity at up to 150 Mbps in an incredibly small package. At just 0.25 inches long by 0.5 inches wide when plugged into a USB port, the USB-WIFINT is barely noticeable. With such a low profile, you don"t have to worry about the adapter snapping off from an accidental nudge. In fact, you won"t even need to unplug it before you stuff your laptop PC your backpack or totebag. Ideal for wireless connections where line-of-sight to access point is available. Consider "high-gain" adapters instead for applications where signal quality is important. Because of its small size, the adapter is especially useful for setting up a separate, peer-to-peer (Ad-hoc) connection between two WiFi adapters. Search "ad hoc wifi setup" for details.
