WiFi Tips

Turn Your Wireless Adapter Off and On

There are multiple access points (APs) in every building. Your computer might be connected to an AP that is too far away to provide a good connection. Turning your wireless adapter off and then back on resets the list of available APs. Your computer may then connect to an AP that is closer.

Update Your Computer's Wireless Drivers

Updating your device’s wireless drivers improves general network connectivity and speed. Go to the device manufacturer’s Web site to download the latest drivers. For Macintosh computers, run Software Update (Apple Menu > Software Update), or For some Windows computers, check the optional updates via Windows Update (Control Panel > Windows Update).

Manufacturer Web Sites:

  • Lenovo users may find the drivers by going to Lenovo then search for the product model.
  • Dell users may find the drivers by going to Dell then use Auto-detect, input Service Tag, or browse for the product model.
  • HP users may find the driver by going to HP then either Browse by Product Category or use “Detect My Product”.
  • Intel based adapter users may update their drivers by going to Intel Download Center then download the “Driver Update Utility”.
  • Realtek based adapter users may update their drivers by going to Realtek Downloads then download the driver

Update Your Operating System

Computers and other devices that are up-to-date may contain many software fixes that optimize performance, security, and reliability. For more information see our instructions on how to keep Windows and Macintosh computers up to date.
Note: Windows users should set Windows as the default manager for wireless connections by disabling third party software. Consult your computer’s Help documentation to learn how.

Use UNC On-boarding process to Set Up Your Connection to eduroam

Windows and Macintosh computers may try to automatically set up a connection to eduroam, but if you haven’t configured your connection using our setup wizard (SecureW2), your computer’s attempts to connect to the network will fail. Your computer may even report that it has successfully connected to eduroam, but you may find that you don’t actually have Internet access or that it is severely limited.  See our eduroam documentation for more instructions on how to configure your connection. After running the on-boarding setup process please verify that your wireless connection is connected to eduroam.

Minimize Wireless Interference Around Your Computers

Signals from wireless-enabled devices (e.g., wireless printers, Apple Time Capsules, Consumer Access Points and Wireless Routers, some gaming devices, Bluetooth devices) and other common appliances interfere with and degrade the campus wireless network, making Internet access slower for you and your neighbors.

In general, to minimize interference, you should keep power, phone, and/or speaker cables as far from your computer as possible. You can also try to find an area with high signal strength.

See the table below for specific devices that cause interference.

Solution

Wireless Printers High Medium Disable the wireless feature in your printer and use a USB cable.
Note: Many wireless printers come with wireless enabled by default. They still transmit wireless signals even though they cannot connect to the campus wireless network.
Consumer Access Points and Wireless Routers High Very Far Don’t install your own wireless routers or access points.
Note: The unauthorized use of these devices on campus is a violation of the ITS Wireless Networking Policy and Network Acceptable Use Policy.
Apple Time Capsules configured to accept wireless client connections High Very Far Disable your Time Capsule’s wireless connectivity and use a USB cable.
Note: Such use of these devices on campus is a violation of the ITS Wireless Networking Policy and Network Acceptable Use Policy.
Microwave ovens
(when in use)
Very High Short Use your oven sparingly and keep it away from your computer’s wireless antennae or adapter.
Some gaming devices
(e.g., XBox 360 controllers and the like)
High Short Make sure that these devices are powered off when not in use.
Bluetooth devices
(e.g., keyboards, mice, headsets and headphones, etc.)
Medium Short Make sure that these devices are powered off when not in use or use wired alternatives.

A fully charged battery may help performance

Some computers will shut off network adapter to save power

Disable Internet Protocol version 6 (IPV6)

IPv6 is the latest metihod of addressing devices on the Internet.  It uses longer addresses to support a greater number of devices, but is not widely used on campus.  Please visit Campus IPv6 Policy for more information about IPv6 and UNC network.  Please visit the documents in order to turn of IPv6 for Mac and Windows.
