Decent wireless network card?

Alright so I've been through two extremely cheap network cards on my computer so far, and typically they've done this thing where they'd be fine (30-70 ping) and then thered be points to where they would get 800-1k ping and sometimes 2k ping. Most of them I've totally destroyed through rage, or by messing with the antenna (or what have you one was a USB) until I got my ping back.

Is there anywhere I can get a network card that will frigen work, and I'm pretty sure it's not my router because I had a laptop which had no problem with internet (other than -2 fps on most games).

I was thinking this one: http://www.amazon.com/gp/product/B0054L9PWO/ref=as_li_ss_tl?ie=UTF

What did you decide on using?

I just bought two D-Link products a DIR-412 3G Wireless Router and a DWA-525 PCI Adapter card. Whilst I had initial setup issues due to the PCI cycling off & on indiscriminately. The actual D-Link interface is very, very good with loads of individual settings you can make changes to. You can even set a White-list for sites to visit or block, it includes up to 24 IP addresses you can incorporate into your personal profile. All linked into a secure Users facility "Hosted @ D-Link"

I use D-Link (DIR 665) too
