Your wireless adapter - the Netgear WG311v3 - is junk. I bought it once half a year ago and found it was junk. Today I was going to buy another wireless card and I didn't even look at this junk card. I hate you. May you burn in hell.
It was a choice between no internet on a computer and having to buy your card (which is junk), and I chose the former.
Please sell your better, more well-supported wireless cards in India. I can't remember the last time I had to search for drivers - oh wait, no, that's a lie. It was when I had to install your WG311v3 (a junk card). For the love of god, leave Marvell behind. I hate them too.
Thank you, A concerned consumer.
