Options for avoiding connection loss due to signal degradation include the following:
- Check your card and AP configurations to ensure they are auto-adjusting data rates. If either device insists on 11 Mbps, then you'll lose the connection rather than fall back to 5.5 Mbps.
- Use a wireless PC card with a stronger on-board antenna. I'm not kidding. PC cards do vary quite a bit, and you might obtain better results with another card.
- Increase overall signal strength in the area where the laptop is located by adding more APs or moving the APs you already have. After all, your goal isn't to provide good signal to an empty room, but to provide acceptable signal levels during normal WLAN use.
- Add an external antenna to get more mileage from existing transceivers. Some PC cards do accept external antennas, but you'll get more overall benefit by adding AP antennas. To learn more about external antennas, read this tip.
