Your Wi-Fi devices can interfere with others’ Wi-Fi connectivity.
- Wi-Fi networks use a range of publicly available, unlicensed radio frequencies shared among numerous types of devices.
- When many devices use these same frequencies, it can degrade Wi-Fi network performance.
- Many devices have an impact — wireless printers, microwave ovens, cordless phones, wireless audio speakers, wireless clocks, projectors, cameras, and gaming controllers.
Wired connection
- Always faster than Wi-Fi.
- Helps free up Wi-Fi for other users.
Reduce Wi-Fi interference.
Avoid using any device that can create a personal wireless network.
This type of ad hoc network is created by individual devices, which can communicate directly with each other without using a router.
Example: For a wireless printer, disable its wireless capability and use a wired connection instead.
NOTE: The most common source of Wi-Fi interference are wireless printers creating ad hoc networks.
Avoid using a personal Wi-Fi router or access point.
These devices significantly interfere with the campus Wi-Fi network.
If you believe that your situation requires a personal access point, please request assistance from the IT Department.
Minimize interference from your other devices.
