Comments about TRENDnet® TEW-421PC 54Mbps Wireless G Laptop Card:

I use this for an older laptop without integrated wireless. As it is older I did not want to sink a lot of money into a card. The sale on this made it fairly affordable. It is workable, although I find that it can be difficult to establish open connections sometimes.
