Wi Fi Recommended Speed and Clarity Test Levels
Clarity is measured in Noise to Signal Ratio
A low noise system will perform better than the Windows XP or other Window's operating systems number of bars indicates.

SNR Cutoff Recommendations by Jim Greir
A couple weeks ago, I ran user-oriented tests to determine the impacts
of SNR (signal-to-noise ratio) values on the ability to associate with
an 802.11b/g access point and what level of performance that you experience.
SNR is what I recommend using to define range boundaries when performing
an RF site survey. For various SNRs, here's what I found for the signal
strength on a wireless laptop (found in the Windows radio status), association
status, and performance when loading the http://wireless-nets.com/staff.htm
webpage...
> 40dB SNR = Excellent signal (5 bars), always associated, lightening fast.
25dB to 40dB SNR = Very good signal (3 - 4 bars), always associated, very fast.
15dB to 25dB SNR = Low signal (2 bars), always associated, usually fast.
10dB - 15dB SNR = very low signal (1 bar), mostly associated, mostly slow.
5dB to 10dB SNR = no signal, not associated, no go.
As a result, I recommend using around 20dB as the minimum SNR for defining
the range boundary.

This test is more consistent in measuring connectivity than the Windows XP.
This test gives the speed of a signal going to a web location and returning.
It can be used to find out the slowest point on the trip to and from.
Many times it is not your computer or the system you are located on.

Ping Time Explanation
<
=100 ms Great, typical of a high-speed cable or DSL connection.
100 to 200 ms Good, common for cable and DSL connections.
200 to 400 ms Fair, usually seen with dialup connections or faraway sites.
400 to 600 ms Slow, either the connection or the remote site is slow.
600 to 1999 ms Poor, high latency. Typical for satellite connections.
>
1999 ms No response, the ping was blocked or the site did not reply.
