ZoomAir 11Mbps Wireless PC Card

Model: 4100

Pros:
– 64 and 128 bit WEP with no throughput hit
– Good performance vs. range
– Comes with Sygate Internet sharing software

Cons:

– Windows only
– So-so client utility

The ZoomAir 11Mbps PC card is your basic 802.11b PC card that uses the
Intersil Prism II chip set
and has a non-detachable, unmovable antenna. 
The antenna is flat and won’t interfere with the adjacent PC card slot, either
above or below it.

The PCI version of the card comes as a separate PCI adapter and PC card,
but the PC card has an SMA style connector with cabled antenna.

There’s one "Link" LED on the antenna section, which shines steadily
when the card detects a signal from another 802.11b station and blinks when
it can’t. The LED doesn’t flicker to indicate network activity.

Setup and client management for the ZoomAir is similar to other PRISM II based
cards, such as the SMC2632W and D-Link
DWL-650
, that use the Neesus client utility, so refer to either of those
reviews if you need details.

Comments: The data shows consistent performance over all tested conditions. 
No SNR measurements could be recorded, since the Client application did not
provide them, but the Client Manager’s worst case reading for Condition 4 was
"Fair" for both signal quality and strength.  

No throughput degradation was found with either 64 or 128 bit WEP enabled.

Summary

The ZoomAir PC card stacks up well against the ever-growing field of 802.11b
client cards, with good performance in all tested range conditions and no WEP-enabled
throughput degradation.  You can find it as low as $100 on-line,
and that includes bundled Sygate 3.1 Internet sharing software as an
added bonus.
