Hi, I have an HP Pavilion 500-009c computer, and I am looking to replace the wifi card. It is my brother's computer and he constantly complains that the existing wifi card inside it is malfunctioning on him while he uses the computer.

The wifi card is an Atheros AR5B125, and there is only one antenna with the computer (2.4GHz).

Now, I already pulled the single antenna further out of the case (using the disk drive flap of the case) in order to improve the signal but it still isn't the greatest due to the positioning of the computer relative to the router (and that's non-negotiable).

So should I upgrade to a new half-size PCIe card (I've seen an Intel one recommended on the forums elsewhere)? Would the antenna be good enough, or should I get new antennae with a cable longer than the existing one, that extend further out of the case?

Or should I just go for a PCIe x1 card with bigger antennas going out of the back of the case?

Hi:

I would remove the card and go for a PCIe x1 card that has external antennas.

You will get better performance from a newer model PCIe x 1 card.

With only one antenna cable a HMC AC card will work but the bluetooth won't because all dual band HMC cards require two antenna cables be connected to them for best performance.

I see that the Joshua motherboard that model comes with has an internal 9 pin USB connector, so you can get a PCIe x1 card with bluetooth.

It should come with a cable to connect the bluetooth from the card to that 9 pin connector on the motherboard.
