Polywell Poly 890FX: Speedy Performance PC Stumbles on Design
It's common knowledge that when PC makers use an AMD processor in a system--especially in the performance PC category --they do so to reduce the overall cost while building a desktop that can still compete against models carrying the best that Intel has to offer.

Monitoring Requirements

There are a few things to consider when you plan to setup wireless traffic monitoring. First you need to determine what kind of traffic you are intending to monitor, to or from your local systems, or to and from a system you do not have direct control of. Second, you need to have the appropriate wireless adapter installed in your system, with its proper driver loaded. Thirdly, you need to have monitoring software in place on that system that can sniff packets on that interface.

Traffic Selection

If you are attempting to monitor traffic to and from a specific system you have administrative access to, then any sniffer capable of attaching to your local wireless interface is all that is necessary.

If you want to monitor traffic between systems you do not have administrative access to, you will need to ensure your adapter has the ability to go into monitor mode. Adapters placed in monitor mode do not normally operate for other connectivity at the same time, so if you use an adapter for Internet access, you will need to have two wireless interfaces installed if you would like to maintain Internet connectivity while monitoring. You will need to place your system kernel in monitor mode in some cases previous to using ethereal. Check your adapter and operating system documentation to determine how to do this.

Wireless Adapters

Some wireless adapters are better suited to sniffing packets than others. Not all wireless adapter can properly detect and report errors, and others have drivers that are not very suited to packet sniffing. Cisco Aironet cards, Prism II cards, and Orinaco Silver and Gold cards are considered to be the best cards to perform monitoring from, but they are only a few of many that have the capability and the proper drivers available. Research which cards are available for the operating system you are intending to use, and procedures necessary for their driver install before purchasing any card.

Wireless Sniffers

A free full-featured multi-platform sniffer which supports most wireless adapters is ethereal. This package is very suitable for debugging communications between systems and formats output in such a way to assist the user in identifying protocol components. It also provides additional information about those protocols that are not always available in other sniffers making it quite simple to use with limited training. You will still be required to understand the protocols you are debugging to get the full benefit of the sniffer output.

Legal Concerns

Keep in mind that monitoring or otherwise auditing networks and systems you do not own may be illegal in your country or state. Consult legal counsel if you are unsure of the legal ramifications when performing any activities outside of your personal property.
