Wi-Fi Interference Sources

How to Identify Wi-Fi Interference

If you're experiencing slow download speeds, high latency or dropped internet connections when using campus Wi-Fi, it's likely that your signal is being degraded or disrupted by physical obstructions or competing radio transmissions.

Wi-Fi is highly susceptible to interference by:

  • other Wi-Fi networks (e.g., personal Wi-Fi access points)
  • competing electronic devices (e.g., microwaves, Bluetooth)
  • physical obstacles (e.g., heavy furniture, concrete walls)

If moving closer to a Wi-Fi access point isn't an option, check the list of common electronic interference sources below.

Common Sources of Wi-Fi Interference

Interference SourceImpactCourse of Action

wireless router

Personal Wi-Fi access points

High

Personal Wi-Fi access points degrade the network speed for all users without increasing personal connection speed.

Turn off your personal Wi-Fi access point on campus.

Note: Personal Wi-Fi access points are prohibited in the residence halls.

camera

Wireless webcams

Medium

Webcams and similar wireless devices sometimes operate on the same frequency as the campus Wi-Fi network, causing interference. 

Replace your webcam with a wired model.

printer

Wireless printers

Medium

Due in part to its impact on network performance, the multicast functionality many Wi-Fi printers rely on for discovery is not enabled on campus.

Turn off the printer's Wi-Fi functionality and use an Ethernet cable to connect it to campus's wired internet.

microwave

Microwave ovens

Medium

Microwaves often leak electromagnetic energy, which interferes with nearby wireless signals.

Avoid using a Wi-Fi device near a microwave oven.

cordless phone

Cordless home telephones

Medium

Older cordless telephones sometimes operate on the same frequency as the campus Wi-Fi network, causing interference. 

Newer cordless phones that use the 1.9 GHz band are less likely to cause degradation.

game controller

Wireless gaming controllers

Low

Wireless game controllers can cause minor service degradation, though they're more likely to experience Wi-Fi interference than cause it.

Use a wired controller to eliminate network degradation and stabilize the connection to your gaming console. When using a wireless controller, turn it off or unpair it when not in use.
