This site is where you can find some common recommendations for resolving wireless connection problems in the UofL residence halls, administration and academic buildings.
This is important especially for computers that have Intel wireless cards. Legacy Intel drivers do not function well with the wireless infrastructure installed at UofL. You can find more information regarding why you may need wireless driver updates.
If you have a computer running the Windows operating system, please check to see if you have Intel Wireless drivers. This can be found by going to:
- Control Panel > System > Hardware > Device Manager
- You can search for Device Manager in the control panel of Windows Vista and Windows 7
- If you have an Intel wireless card, please update the drivers by going to http://www.intel.com/support/wireless/wlan/sb/cs-010623.htm
Ulsecure uses your Active Directory login. This login is the same that is used for UofL exchange (outlook) email (faculty/staff) or UofL cardmail email (student). Please verify that you can login to either your UofL exchange (outlook) email, (faculty/staff), or UofL cardmail (students) email. If you cannot login to your email account then you may not be able to login to ulsecure wireless. You may need to change your password.
If a password or setting is wrong and is stored in the ulsecure profile it may be preventing you from connecting. For instructions on how to remove ulsecure wireless network select your operating system: Windows XP, Windows 7, Mac OSX 10.5-10.6, Mac OSX 10.7-10.8, iOS, Kindle Fire HD and Android. Once removed follow the ulsecure wireless configuration guides to connect to ulsecure.
Some operating system/computer combinations are capable of throttling the power delivered to a wireless card when it is either not heavily used or when the computer is in sleep mode. This can cause some connection problems or result is slower connectivity. If you're having trouble with the wireless network, please try to disable this feature.
Each wireless card and computer manufacturer has a different way of disabling the radio or wireless card antenna. If you are receiving very low or no signal strength from the UofL wireless networks please be sure that your radio is on. First look for a hardware switch on your device. Some devices implement a hardware switch using the "Fn" key. Hold down "Fn" and press the key with a radio tower. You should get a message telling you if you have just turned WiFi on or off. Refer your laptop manual for more information.
Here are a couple of examples, however this doesn’t represent all laptops.
For a full description of why disabling IPv6 can help you get a better connection on the UofL wireless network, please see the following: Disable IPv6
For a full description of why devices have trouble connecting after being in "Sleep" mode, please see the following: Sleep Mode

In addition to active interference caused by other radio
waves, wireless network signals can be disrupted by physical obstacles
including some types of windows, building materials, furniture, and appliances.
Often refrigerators placed in the line of sight or near a wireless device can
cause serious degradation of signal.
If you are noticing problems connecting to the wireless network, please keep these questions in mind:
Do you have a cordless phone?
Can you see or connect to networks not called "ulsecure"?
How far away is the nearest access point?
Are there large appliances, doors, walls, metal objects or structures between where you work and where the closest access point is?
