Wireless Internet - Interference Sources

Wi-Fi communication is extremely susceptible to interference caused by competing radio transmissions that operate in the 2.4GHz and 5GHz bands. Wi-Fi interference can result in low to no wireless signal, extremely slow download speeds, dropped Wi-Fi connections, and increased delay for Internet browsing.

Interference Sources

UCB Wireless utilizes state-of-the-art technology; however, there are still ways that the service can be degraded by interference sources. Some interference sources are more impactful than others (such as personal Wi-Fi access points), but all of the following can cause degraded service.

Interference SourceImpactCourse of Action
wireless routerPersonal Wi-Fi access pointsHIGHPersonal Wi-Fi access points degrade the overall speed of the network for all users and does not increase personal connection speed. Removal of these access points is the best way to improve the wireless experience for all users. Please note that personal Wi-Fi access points are prohibited in the residence halls.
game controllerWireless game station remotesLOWWireless gaming console controllers may interfere with the network speed. The degradation is minor, but can be eliminated completely by using wired controllers.
printerWireless printersMEDIUMWireless printers can degrade the wireless connection for users in the vicinity of the printer. The interference can be easily addressed connecting the printer into an ethernet port and/or turning off the Wi-Fi functionality.
cameraNon-Wi-Fi Wireless video camerasHIGHWireless computer webcams can cause a small amount of network degradation. Replacing the camera with a wired model will remove the interference.
microwaveOlder microwave ovensMEDIUMOlder microwaves sometimes operate on the same frequency as the network, causing interference. Newer microwaves will likely not cause degradation.
cordless phoneCordless home telephonesMEDIUMUsing cordless home phones may cause interference with the wireless network speed. Cordless phones without 2.4GHz or 5.8GHz frequency will not interfere with the campus network.
