Best Wi-Fi adapter for under $20

I'm looking for a Wi-Fi adapter wether it be a PCI express or a USB plugin. Thanks

 

(PS- I also have an Xbox 360 Wi-Fi adapter and I know it works on PCs but the drivers are a pain in the ass)

I went through about a billion of these over the winter when I was having wicked Wi-Fi issues.  After trying no less than five different brands (Zyxel, Netgear, Linksys, Rosewill and Asus) I was willing to pay the $30 because at that point I was so frustrated, but you might be able to find it for closer to $20 elsewhere.

Ok, I will probably buy that one. Thanks.

Just go with this - http://www.newegg.com/Product/Product.aspx?Item=N82E16833106135 . For $35 bucks dual band intel top of the line for the desktop space. Intel is the unquestioned market leader in NICs so you might as well just go with their best offering (at a not too bad price) and call it day. 

Kk, I'll look into it. Thanks!

I think Rosewill have one or two for $12.99 and they seem to get the job done.

Yeah I saw them but I just wanted to get some feedback abut others. :D

I had very bad experiences with my Rosewill and both my Netgear and Verizon provided Actiontec router.  Could have just been a router issue, but I could not get it to stay connected.
