Overview
Academic Technology Services began to deploy the next generation of wireless service throughout campus beginning Summer semester 2008. This new service is named MSUnet Wireless 2.0 and is an upgrade to the current MSUnet Wireless service.The Computer Center was the first of many buildings to have MSUnet Wireless 2.0 installed. The buildings included in the initial deployment had the original MSUnet Wireless service (if present) removed and replaced with MSUnet Wireless 2.0. However, buildings not part of the initial deployment may have both services (see below for a list of buildings). This information will be made available to the ATS Help Desk as it is known.
MSUnet Wireless 2.0 offers a number of new enhancements over the current generation wireless service. MSUnet Wireless 2.0 will support all of the current wireless standards (802.11a/b/g) and add support for 802.11n. It will also support a greater number of users per access point.
802.11n offers a significant improvement in speed over current wireless standards. 802.11n can operate at either 140Mbps or 300Mbps depending on the wireless adapter and distance from the access point. Wireless adapters which support channel bonding can support a throughput up to 300Mbps; those without can support a throughput up to 140Mbps.
Unlike previous 802.11 standards, 802.11n has the ability to run in both the 2.4GHz and 5GHz wireless bands. MSUnet Wireless 2.0 will support 802.11n in the 5GHz band only.
MSUnet Wireless 2.0 will still offer authenticated and guest service. Authenticated service is available to users with a valid MSUNet ID and Guest service available for those without. Users can choose the SSID MSUnet Wireless 2.0 for authenticated access and the SSID MSUnet Wireless Guest 2.0 for guest access.

Problems with Intel 4965 Wireless Adapter
PC's (not Macs) may experience frequent disconnections with MSUnet Wireless 2.0 if they have an Intel 4965 Wireless Adapter. PCs with this adapter can be identified by looking in the Device Manager (instructions below) and then resolved by updating to the latest Intel driver. (Refer to TB10607, "Intel Wireless Driver Installation" for instructions.)Finding the Device Manager and Adapter
Step 1:- Go to the "Start" menu and click on "Settings".
- Click on "Control Panel" and double click on the "System" icon. The System Properties window displays.
- Click on the Hardware tab and select "Device Manager".
Step 2:
- From the Device Manager window, scroll down and click on "Network Adapters".
- If the adapters listed include Intel(R) Pro/Wireless 3945ABG or Intel(R) Pro/Wireless 4965ABGN you will need to update your drivers for best performance. Please see Techbase article 10607 for help updating your drivers.
Macintosh disconnection issues
A few Mac OS 10.4.11 users have experienced issues with repeated disconnections and reconnections to Wireless 2.0.To resolve these issues, run Software Update and apply the latest Airport Extreme software patch.
