Wi-Fi Commonwealth University provides wireless networks deployed across the Bloomsburg, Lock Haven, and Mansfield campuses. These networks are available to faculty, staff, students, and guests. More information is available on the pages below. Wi-Fi Overview Multiple wireless networks are available depending on the use case. The preferred network for personal phones, tablets, and computers is CommonwealthU, which allows you to connect using your CU username and password. Some personal devices do not support username/password wireless authentication. These devices should use CU Registered or CU Registered Open instead Check out the locating your device's MAC address page for step-by-step instructions on connecting and registering common devices. If you are encountering issues connecting to Wi-Fi, please see the Known Wi-Fi Issues page for possible solutions. Device Registration Personal devices connecting to CU Registered or CU Registered Open must be registered. More information about this process is available in the Network Registration section. You may need to disable MAC address randomization on devices before connecting to CU Registered or CU Registered Open.

More information about this process is available in the Network Registration section Wi-Fi Requirements Supported Devices Our network supports most modern laptops, smartphones, tablets, and other Wi-Fi–capable devices. Recommended Hardware For the most reliable performance – especially in areas with high signal congestion or heavy device use – we recommend using a Wi-Fi 6 (802.11ax) adapter. For desktop computers, adapters that include a desktop cradle and larger antenna tend to provide: Better signal reception when placed away from the computer or under a desk Improved stability and speed in dense wireless environments Fewer dropouts and better performance during peak usage The Netgear Nighthawk A8000 and TP-Link Archer TXE50UH are both good examples of a device that should work well in most situations. Wi-Fi Performance Our Wi-Fi network is designed to provide fast, reliable access across campus. However, wireless performance can be affected by many factors – some within our control, and others within yours. This page explains what can impact your connection and how to get the best possible experience. Wireless Interference Wi-Fi operates in shared frequency bands, so other devices using the same frequencies can cause slow speeds, dropped connections, or higher latency. Common sources of interference include: Non-Wi-Fi wireless devices, such as: Wireless HDMI transmitters Bluetooth speakers and headphones Wireless keyboards and mice Game controllers Personal routers, hotspots, and extenders, which create competing networks that are not optimized to avoid interference Microwave ovens, especially when located near access points When possible, use wired peripherals or turn off unnecessary wireless devices near your computer. Device Hardware and Placement Not all Wi-Fi adapters perform equally. Performance can be affected by: Older adapters that only support 2.4 GHz or earlier standards like 802.11n Weak antennas or adapters embedded behind metal cases or desks Adapters without cradles, which are limited by their position and can’t be moved for better signal We recommend using a Wi-Fi 6 (802.11ax) adapter with a desktop cradle and larger antenna. These models can be placed away from your computer, improving reception and stability. Environmental Factors Wi-Fi signals can be absorbed or reflected by: Metal surfaces and filing cabinets Concrete walls Water (including aquariums and people) Repositioning your device or adapter just a few feet can make a noticeable difference. Prohibited Wireless Devices To ensure stable, high-performance Wi-Fi across campus, certain types of devices are not permitted. These devices interfere with campus Wi-Fi operations and can cause widespread performance issues for nearby users. Prohibited Device Types Category Examples Personal routers and access points Home Wi-Fi routers, mesh nodes, “travel” routers, wireless printers acting as access points Mobile hotspots and tethering Phone or tablet hotspot mode, dedicated hotspot devices (e.g., Verizon Jetpack, Nighthawk M1) Wi-Fi extenders and repeaters Range extenders, signal boosters, wireless bridges Ad-hoc or peer-to-peer networks Computer-to-computer (ad-hoc) Wi-Fi setups Additional Notes Do not plug in or power on these devices anywhere in campus buildings. If you need additional coverage or signal strength in your area, contact the Technology Help Desk. We’ll evaluate the space and, if appropriate, make adjustments to our managed access points. Personal devices like phones, laptops, tablets, smart speakers, and IoT devices are allowed – as long as they connect to the official campus Wi-Fi and do not broadcast their own networks. Known Wi-Fi Issues Apple Devices Apple Devices Not Prompted to Register If you don't automatically get prompted to register your device when connecting to CU Registered Open for the first time: Make sure auto-login is enabled in CU Registered Open settings. If you do not have an option for auto-login, try forgetting the CU Registered Open network and setting it up again. As a last resort: Open a web browser and visit any website to manually initiate the registration process. Repeatedly Prompted for Wi-Fi Password Apple devices that are signed into the same iCloud account will sync the Wi-Fi password for CU Registered to all other devices. To avoid issues, you must specify the same password on all Apple devices during registration. Once you encounter this problem, it may be necessary to forget the network on all devices and delete the Wi-Fi password from your iCloud account. To forget the Wi-Fi network: Go to Wi-Fi settings Click the three dots or tap the blue information icon next to CU Registered Select Forget This Network Repeat this procedure on all Apple devices Next, on an Apple Mac: Click the magnifying glass 🔍 near the upper right corner Type Keychain Access and press enter Search for CU Registered Select the first item, then press the delete key It may be necessary to enter your computer password to confirm this change If there are multiple entries, delete them all Once you have forgotten the network on all devices and removed it from your iCloud keychain, make sure you have the same password set for all devices using the Network Registration portal at https://netreg.commonwealthu.edu.
