Here you can find some common recommendations for resolving wireless connection problems in the MIT residence halls and academic buildings.
This is important especially for computers that have Intel wireless cards. Intel drivers prior to Fall 2009 do not function well with the wireless infrastructure installed at MIT.
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
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 MIT 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.
Most operating systems allow for an order of priority that wireless networks will be connected to. If you notice that your computer is connecting to a wireless network that is not one of the recommended MIT wireless networks, or if you want to always prefer 5 Ghz connections, you should update the order of your preferred wireless networks: How to remove preferred or saved networks from your wireless settings.
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 "MIT"?
- How far away is the nearest access point?
- Are there any large appliances, doors, walls, metal objects or structures between where you work and where the closest access point is?
|Please DO NOT modify the antenna alignment.|
The wireless antennas are aligned vertically by the Network Infrastructure group to provide faster connectivity. Modifying the antenna alignment may diminish the effectiveness of the access points. The correct alignment is the two top antennas facing straight up and the two bottom antennas facing straight down.
IS&T is committed to resolving problems and concerns that are reported on the wireless network. Since there are many different types of outages on the wireless network, IS&T needs some additional information to help resolve them and determine if there are any trends. Connection issues should be reported to the IS&T Helpdesk by email, phone or by filling out a help request.
