Cons: Overheats. Loses signal quite often when compared to my dells with built in Wifi using 802g. I think the overheating causes the unit to lose signal or degrade signal. Sometimes its just plain weak and doesnt operate fast on startup.
Other Thoughts: I have many devices that use Wireless and never have a problem with my other 2 laptops. They both have built in WiFi and never give me a problem. My Dells range around 90-95% of total bandwidth compared to this device that gets around 10% or less of total bandwidth. This device is weak but shows a strong signal in windows at 54mbps. Buy a better and more experienced product like a Dlink or Linksys.
-if it overheats too much dont bother getting it unless your prepared to modify it to cool it down
-the person that posted this compares it to other wifi cards...if an internal card is performing better than an external card with a 2bdi antenna..
- should also note that db > dbi and you will notice the difference when you compare the two
