    Comments about TP-Link TL-WN861N 300Mbps Wireless Mini PCI Adapter:

    I upgraded my ThinkPad T42 from a 54g to this incredible, 300N. With the ThinkPad, you get the 1802 error, but a little BIOS/Software tweak and it accepted the faster card. The TP-Link 300N Wireless card is VERY stable. This thing has NO disconnects and is constantly connected at 300mbps. Makes transferring files and streaming video seamless with no problems. I Highly Recommend!!~Dave Schrom [@]
