Wireless card with poor reception and dropping connection

Hey guys. I have an HP m6-k015dx and it has an intel centrino 2230 wifi card in it. I also have an old, netgear wna 1100 usb wireless adapter. The wireless usb adapter I have gets extremely better wifi connection that the internal adapter and the signal strength on the networks won't fluctuate. Are there any settings I can change on the intel adapter, or can I buy a new internal adapter to replace the intel to get better reception? Thanks.

Does anybody have suggestions for a good wireless card? The 2230 is really ticking me off because it doesn't have 5ghz support and reception is abysmal.

Try this. It's got really good rating on Amazon and it's also dual band: Amazon.com : Broadcom Wireless 802 11/a/g/n Internet WLAN Adapter Card for Laptops & Netbooks : Computers & Accessories

I am assuming I have to unlock my bios in order to use an aftermarket card. I think y laptop only has two antennas on it, and if I'm not mistaken I need a third antenna to get true wireless n.

You don't need to have 3 antennas to get true Wireless-N. 2 antenna configuration will give you 300 Mbps speed on a 2x2 card.

Alright. I'll have to see if I have to unlock my bios. Thank you for the reply.
