Wireless Internet - Interference Sources

Wi-Fi communication is very 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.

WCU's Wireless Networks and Interfering Sources

WCU’s RamNet Wireless service utilizes state-of-the-art technology.  However, there are still ways that the service can be impacted by interfering sources.  Some interfering sources are more impactful than others (such as personal Wi-Fi access points), but all of the following can cause poor Wi-Fi service.  A list of commonly seen interfering devices are listed below.  Please eliminate the use of these devices while on campus and make sure they are not broadcasting wireless signals in the background.  Doing this will create a positive wireless network experience for all those located on campus, including yourself.

Interference Source Impact Course of Action

Personal Wi-Fi access points and routers


Personal Wi-Fi access points and routers 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 and routers are strictly prohibited from being used on WCU’s campus locations including in the residence halls.

Hotspots / MiFis / Wi-Fi Tethering


Like personal Wi-Fi access points, using a hotspot (such as the hotspot feature on your mobile phone) interferes with other wireless devices and degrades the overall speed of the network for all users.

Please note that the use of hotspots on WCU’s campus are strictly prohibited, including in the residence halls.

***Wireless hotspots are only permitted to be used off campus.***

Wireless Printers


Wireless 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.

Wi-Fi Wireless video cameras


Wireless computer webcams can cause a small amount of network degradation. Replacing the camera with a wired model will remove the interference.



Microwaves sometimes operate on the same frequency as the network, causing interference. Newer microwaves will likely not cause degradation.

Cordless home telephones


Cordless home phones may cause interference with the wireless network speed. Cordless phones without 2.4GHz or 5.8GHz frequency will not interfere with WCU’s campus network.

Wireless gaming console controllers


Wireless gaming console controllers may interfere with the network speed. The impact is minor but can be eliminated entirely by using wired gaming controllers.
