I've had a bumpy ride this weekend.

It's not possible to put an ethernet cable from the router to my PC, so I was using a ASUS PCE-N15 wireless PCIe card. I've had this since my previous PC, it always just worked.

My bandwidth seems to be worse then with my laptop though, so I thought of putting it in another PCIe slot, to clear some space between audio/video/usb cabling and the antennas.

After completion of this cunning plan, windows nor the motherboard seemed to be able to detect the PCIe device. It It wouldn't detect in any of the other standard PCIe slots any more either.

I thought I broke the thing by plugging it in and out too much, so I ordered a TP-Link one instead, with more antennas. This arrived this morning. I plugged in, same problem.

I read somewhere that PCIe slots compatible, no matter what size, so I took out my GPU and tried it in a PCIe x16 slot and it worked directly. I tried it in the normal PCIe slot, still worked. I put my GPU back, still worked.

So, can anyone explain to me what happened here? And are there cool things I can do with 2 wireless adapters?
