You do not need a crossover at all.

Argh, you're right. Just about everything that does gigE also does
auto MD/MDX, a very nice feature that makes crossover cables obsolete.

I purchased three of these Airlink Gigabit USB adapters expecting to
speed up local throughput on machines plugged into a Netgear Gigabit
switch. I installed one in a laptop that was running with a Linksys
PCMCIA 54 wireless adapter.

Much to my surprise, the wireless adapter was faster. Testing speed via
Speakeasy.net/speedtest to a local server gave 5,xxx kbps up and 500 up
with the gigabit adapter. Speed was 12,xxx kbps down and 1,7xx up with
the wireless. I have fiber from Verizon quoted as 15 kbps down 2k up.
Other PCs on the network with regular 10/100 wired adapters generally
achieve the 15/2 quoted by Verizon.

Is there some configuration on the Airlink 101 that I'm missing? If
they adapt automatically to a crossover cable, I'd think they would
configure themselves for faster throughput than a wireless adapter.
Anyone else have speed issues with the Airlink Gigabit USB adapters?

You were using CAT 5e cable werent you?

Yes. But, I can't imagine that regular CAT 5 would cause a Gigabit
adapter to be slower than a wireless card. The source was ~15K to the
Internet.

I didn't even bother to compare speeds using a NAS with RAID 5 and
Gigabit support.

If you use standard CAT5 (not CAT5e, CAT5E or even CAT6), it is possible
to get a Gigabit Link.

That is it though...just the link.

You will likely see lots of errors (retransmits, reassemblies, etc).
What happens in these cases are that even though the connection looks
fine, it slows down considerably since it has to retransmit many packets
many times before it works.

Use the right cable for the job.
