Hello everyone, it seems that the wireless pci adapter isn't working well in my pc, i have only 2 pci slots and i tried the 2nd one which is just above my (600w) psu and i can't even make a connection, the 1st slot is just below my (hd 7870) video card which actually perform way much better but when i start to use my video card i lose connection, how can i fix this!!!!!!

Question for you. Do you mean to say you are using a PCI/PCIE Wifi Adapter, not a wireless PCI adapter?

If your video card powers up and disconnects you from Wifi, then you should throw away the card and buy a USB one. You could alternately increase the RF shielding between the video card and wifi card, but the time and cost required to do so would be prohibitive compared to buying a replacement USB stick, and increasing RF shielding will decrease range/signal strength for your wifi card.

I always recommend against internal wifi adapters in desktop PC's, there is way to much EMF's flying around with fan's power supply's video cards and HDD's all in such a small proximity that wifi connections failing is the norm.

I find that USB adapters can actually have better signal strength than desktop adapters with the attached antenna.

The biggest reason is that a USB adapter can be used with an extension cable (many of them even come with one) and the device can easily be moved to an ideal position to increase signal strength. Where as the desktop Wireless cards either have to penetrate the PC, bounce off a refractable object, or have their backsides facing the router to get a wireless signal.

As for transfer rates, unless you using a 500Mbps modem or about to get Google Fiber you will never see the speeds of triple band wireless n, let alone wireless ac.

USB2 wireless N adapters are fine for internet and video streaming, USB3 N/ac adapters are better but also about twice as expensive.

you guys did not help him at all, i assume. i think he was asking why the card would make wifi detections 'impossible' and im having the same problem right now lol
