Desktop wireless USB vs PCI adapters

I have noticed that my USB wireless adapter gives a much better signal strength than my PCI internal adapter. Any reason for this? As I thought it would be the other way round??

I've noticed this too and was about to ask the same question.

Are both at the rear of the machine or just the PCI?

PCI internal adapter has an aerial at the rear of the case and the Belkin USB adapter sits on a small stand with a wire attached to a USB port.
Maybe it's because I went for a cheapo internal card...

Just the PCI is at the rear the USB is on the front. Would that really make such a difference in strength?

ezjabutt, hope you don't mind me joining you on this thread.

Yes it could easily make a noticeable difference.

As you have not reported the relative strengths it is difficult to judge.

can make a difference also if either are wireless n adapters if you are using a wireless n router.

An aerial on a PCI wireless card tucked away at the back of the computer can lead to poor signal strength as the others have said. I had this problem too. As the aerial was removeable, i bought a desktop aerial and cable from Maplins and the signal strength was restored.

That's not a bad idea thanks.

Its not where the card is, Its wire that hangs out of it that matters. If its in a corner its not going to pick much up. Antenna needs to be in free space as far as you can make it, i.e not a corner or back of PC
