Who can use the wireless network?
UCSD affiliates (faculty, staff, and students) and guests of the university can use the network. The UCSD-PROTECTED service is recommended for affiliates and UCSD-GUEST for visitors.
Where can I use UCSD's wireless network?
Wireless service is available in most buildings and public areas at UCSD. The UCSD Medical Center also maintains a wireless service.
Which Macintosh platforms does UCSD's wireless network support?
UCSD supports iPhone, Mac OS X 10.5.x and 10.6.x and many 10.4.x machines. All patches must be installed, including those for Airport. To ensure your machine has the latest updates, run Software Updatefrom the Apple menu.
Does it matter how many people are using the wireless network at one time?
Yes. The network gets slower as more clients connect through the same wireless access point (AP). The capacity available in an area is a function of the number of APs, the physical environment, and the kinds of clients trying to use the service. Note: You will notice performance changes more easily on a wireless network than with a wired network connection.
Does UCSD recommend a particular wireless card? Which wireless card(s) are supported?
Most Wi-Fi cards with current updates are supported. Check the manufacturer's website to make sure your card is updated. For questions or problems with Wi-Fi cards, contact your department's computing support staff .
How do I connect to the wireless network?
Follow the documentation on the
Wireless Overview page to configure most systems, including PDAs
Is there a charge for establishing a wireless connection?
You don't need to pay a service charge because wireless service is funded by
NGN. However, you may need to purchase a wireless card if you have an older machine. Newer machines come with wireless cards.
Do I have to log on (authenticate) every time I want to use wireless services?
Yes, you must log in daily if you're using the UCSD-GUEST network. No, if you're using the UCSD-PROTECTED network, but your machine must be set to save your username and password (cache your credentials - most machines are set to cache).
Can I do everything with a wireless connection that I could do with a wired connection?
No, not everything. Do not attempt to run a server from a wireless connection. Large file transfers are not appropriate from the wireless network. Wireless is an extension of the wired network, not a replacement.
How fast is a wireless connection?
Wireless provides a network connection slower than a wired Ethernet network. The performance of the network depends on many variables, including signal strength. The speed of your connection will probably drop as more users in your area connect.
I connected to the campus wireless service, but was directed to Blink. What happened?
Why can't I establish a connection to the UCSD wireless network? I don't have a problem with other wireless networks.
Your DNS server and search domain settings may be incompatible with the UCSD network. Some wireless Internet providers require certain settings configured for their network. Before connecting to a new network, remove the DNS server and/ or search domain information from your wireless network preferences.
Why is my wireless connection disrupted more often than my wired network connection?
The dynamic nature of a wireless network's radio frequency is susceptible to obstructions such as walls, bookshelves, large metal objects, and trees. Microwave ovens, cordless phones, baby monitors, and plasma cutters also operate on the same frequency as the wireless access points and can cause interference as well. Incorrectly configured clients can also disrupt your wireless network connection.
Make sure you have installed all available patches for your PC wireless card. Check the manufacturer's website for the latest updates as older versions may not work with the campus network. Macintosh users should install all patches, including those for Airport. Run Software Update from the Apple menu. Note:The wireless network is not intended as a replacement for the wired network. If you are working from a fixed location, you should use a traditional Ethernet connection.
What do I do if I'm getting poor signal strength?
If you're in a building where wireless is supported but you're not getting a good connection because of poor signal strength, you should contact the
ACT Help Desk, (858) 534-1853.
What do I do if I'm getting poor signal strength?
If you're in a building where wireless is supported but you're not getting a good connection because of poor signal strength, you should contact the
ACT Help Desk, (858) 534-1853.
How can I get a guest wireless account for a guest or conference attendee?
Can I set up my own wireless Access Point (AP) on campus?
In general, no. To set up a special/ researcher wireless AP, contact ACT before you install your own wireless AP on campus, to avoid potential interference with UCSD's wireless network. You cannot deploy a wireless AP without ACT approval. Any wireless APs not deployed by ACT or with ACT's permission can be removed without notice. To request a special/ researcher wireless AP, complete a
Customer Service Request (CSR), and choose
Wireless from the
Select a service menu.
