Systems and methods for determining the presence of a wireless network connection point based upon wireless network characteristics. Examples of such characteristics include, but are not limited to: message length, repetition rate and response timing. These types of characteristics are used to differentiate various types of wireless networks from other radio frequency signals within a given band. The output of the locator is compared against desired thresholds to indicate signal strengths roughly corresponding to current wireless networks cards.

What is claimed is: 1. A method of determining a presence of a wireless network connection point using a portable electronic device before powering on a portable computer, the portable computer capable of connecting to the wireless network connection point, the method comprising: detecting a wireless beacon signal having a repetition rate; upon detecting the wireless beacon signal, evaluating the detected wireless beacon signal; based on the evaluation, indicating the presence of a wireless network connection point if the repetition rate of the wireless beacon signal is within a predetermined repetition rate range using the portable electronic device; and powering on the portable computer after the presence of the wireless network connection point is indicated by the portable electronic device, the portable computer capable of connecting to the wireless network connection point. 2. The method of claim 1, further comprising receiving an input to search for the presence of the wireless network connection point at the portable electronic device. 3. The method of claim 2, wherein the input comprises a manual input. 4. The method of claim 1, further comprising manually powering on the portable computer and connecting to the wireless network connection point. 5. The method of claim 1, wherein the range of the predetermined repetition rate range comprises a range between 5 and 20 times per second. 6. The method of claim 1, wherein indicating the presence of a wireless network connection point comprises indicating the presence of the wireless network connection if a pulse length is within a predetermined range. 7. The method of claim 6, wherein the pulse length comprises a pulse length between 200 and 1200 uSec. 8. The method of claim 1, further comprising indicating a strength of the detected wireless beacon signal. 9. The method of claim 1, further comprising indicating that no wireless connection point is detected if the repetition rate of no wireless beacon signal is within the predetermined repetition rate range. 10. The method of claim 1, wherein the wireless beacon signal comprises a 802.11 wireless beacon signal. 11. A portable electronic device adapted to perform the method of claim 1. 12. The method of claim 1 wherein the portable electronic device detects only an 802.11 b signal. 13. The method of claim 1 wherein the portable electronic device comprises only one control button. 14. The method of claim 1 wherein the portable electronic device comprises an LED, which lights up when the wireless beacon signal is detected. 15. A method of determining a presence of a wireless network connection point using a portable electronic device before powering on a portable computer, the portable computer capable of connecting to the wireless network connection point, the method comprising: using the portable electronic device to detect a wireless beacon signal having a repetition rate, wherein the portable electronic device indicates the presence of a wireless network connection point if the repetition rate of the wireless beacon signal is within a predetermined repetition rate range; and powering on the portable computer after the presence of the wireless network connection point is indicated by the portable electronic device, the portable computer capable of connecting to the wireless network connection point. 16. A portable electronic device adapted to perform the method of claim 15. 17. The method of claim 15 wherein the portable electronic device comprises a dipole antenna. 18. The method of claim 15 wherein the portable electronic device comprises a printed dipole antenna. 19. The method of claim 15 wherein the portable electronic device comprises an LED, which lights up when the wireless beacon signal is detected.
