    Can I use a notebook computer or PDA?

    You can use a Wi-Fi enabled notebook (laptop) computer or PDA on the Stony Brook Medicine Wi-Fi network. For more information, please view our system requirements.

    Why is my computer saying the signal is weak?

    Wireless signal is strongest when the Wi-Fi enabled computer is near a wireless access point (WAP) and there is minimal or no obstruction in between. Examples of obstructions are walls, doors, tall cabinets and shelves, stacked boxes, and even people.
    Stony Brook Medicine has deployed numerous WAPs throughout the indoor wireless locations and have performed extensive surveys and studies to ensure ample coverage. When your computer displays that the wireless signal is weak or poor, this either means that you are not near a WAP or there are obstructions that degrade your wireless signal.
    Another cause of a weak signal may be due to interference. In the SBUMC Wi-Fi network, wireless network users (patients & guests) are susceptible to interference caused by, say, Bluetooth devices, 2.4GHz cordless phones, and even old/leaky microwave ovens. All of these interfere with 802.11b/g wireless in general, thus degrading the wireless signal on your computer.
