No, USB 2.0 is way too slow for 802.11ac that outperforms GBE.

Both USB 2.0 and PCI are orders of magnitude faster than real-world wifi. Even
ISA will give wifi a run for its money. I recommend you not bother with wifi if
you care about network performance.

USB 3.0 to Gigabit Ethernet dongles exist, and are cheap. They should work in
your machine's USB 2.0 port (which now becomes the limiting factor) and you can
expect to see throughput of about 300Mb/s half-duplex with that arrangement.

OT: PCI Ethernet or USB 2.0 ethernet?

[W2HX via cctalk]

Friends,

I have an instrument that has an intel motherboard with 400 MHz FSB PCI (not 
PCI-e). It has a 100 mbps Ethernet card and it would be very useful to get 
faster networking. The chassis of this instrument is such that I cannot fit a 
traditional PCI 1GB Ethernet card (I've tried). So I will have to go wifi 
(which I can make fit because I can remotely locate the wifi antenna). I have 
802.11ac both 2.4 and 5 GHz available. While it certainly won't get as good a 
throughput as a dedicate GB Ethernet card, this is my only option.

The question is, whether you think I would be better off using PCI wifi card or 
a USB-wifi adapter. I should mention the USB on this instrument is USB 2.0, the 
spec for which claims up to 480 Mbps.   Anyone have an opinion which might get 
me better results? The wifi infrastructure is one constant in this scenario, 
just looking to see pci- or usb-based wifi card.

Since this is wildly off topic, please respond to me directly so as not to 
bother everyone else :)
