There is not a pervasive wireless network across campus. However, most buildings with public areas have substantial coverage. (For a list of buildings covered by HD Wireless, please read this article.)
Two different network access types have been made available:
- Open portal to the Internet.
- No data encryption.
- Users will be allowed to connect only after agreeing to the terms of an Acceptable Use Policy (AUP).
- Net ID and password NOT required.
- Provides Internet access to BYU and non-BYU websites.
- No access to the private BYU network.
- The bandwidth for BYUGuest access is not throttled. There should be no speed difference between Guest and Secure.
- Secure portal to the Internet.
- Data sent between this device and the BYUSecure Network is encrypted.
- Users will authenticate with their BYU Net ID and password.
- Users must be an active eligible to register student or current employee of the University.
- Users will also agree to terms of an Acceptable Use Policy.
- Users will be allowed access to the BYU Network as well as the Internet.
The wireless 802.11n standard is recommended. Support for 802.11b (outdated wireless standard) has been discontinued due to the impact on the network when low bandwidth devices connect. If you are using old network devices, you will want to replace any that rely on this standard. Typical devices that are impacted are old PCIA cards, early USB wireless devices, and handheld scanners.
Connecting to the BYU Network
To access the list of available networks:
Click on the wireless icon in your system tray in the lower right corner of your desktop if available. Users of older versions of Windows can choose Start > Connect To: > Show all connections. Then, select the desired network (BYUSecure or BYUGuest). Open a browser such as Google Chrome and navigate to Google or another website. If you chose the BYUSecure network, you will be prompted to log in using your BYU NetID and password. If you chose the BYUGuest network, you will be prompted to agree to the Acceptable Use Policy.
Click on the wireless icon in the upper right corner of your desktop, verify your "AirPort" or wireless connection is on, and then choose Join other network > Show Networks. Open a browser such as Google Chrome and navigate to Google or another website. If you chose the BYUSecure network, you will be prompted to log in using your BYU NetID and password. If you chose the BYUGuest network, you will be prompted to agree to the Acceptable Use Policy.
List of Ports open on BYUGuest:
- HTTP - Port 80
- HTTPS - Port 443
- UDP 500
- TCP 10000
- GRE Protocol
- ESP Protocol
- AH Protocol
- POP3 and Secure POP3 (TCP 110,995)
- IMAP and Secure IMAP (TCP 143,993)
- SMTP and Secure SMTP (TCP 25,465,587)
- SSH (TCP 22)
- Windows RDP (TCP 3389)
Also realize that only public BYU (128.187.x.x) and internet addresses are accessible. No 10.x.x.x access is permitted.
Unable to get a valid IP address or to connect when there are many users to an access point
With pervasive wireless, there are a limited number of connections available per Access Point and if all of these connections are in use, then users will be unable to connect to either BYUGuest or BYUSecure. When an Access Point is full, users will still be able to see the SSIDs, they will just either connect very slowly or not at all until someone else drops off. In buildings with Xirrus arrays, you can check to see if the array is full by using XMS (KB0024408).
Handheld Device Support
If a user has a handheld device capable of connecting to the internet via web browser (iPhone , iPod Touch, smartphone, etc.) make sure they open a web browser before trying to connect to the Secure network and enter their BYU Net ID and password. Failure to open a web browser first may result in an error message and failure to connect to the network. (A user may run into this situation if they try to connect to the network and use a wireless app that doesn't require a web browser.)
Problems with "Sleep Mode"
An issue commonly experienced with laptops is when they are closed or put into sleep mode, carried to another area of campus, and awoken. The computer will still recognize being connected to the network and will often times work as such. On occasion, however, a device will act as though they are connected but will be unable to function properly on the network. The only workaround for this is to disconnect from the network before putting it in sleep mode and then connecting once the computer is awake again.
