General ResNet Information

Q: What is ResNet?
A: ResNet (short for Residential Networking) is the physical network that provides each on-campus residential a network port in their room and a connection to residential wireless access points.

Q: What does ResNet provide?
A: ResNet provides access to UC San Diego's electronic resources and educational/research related material on the Internet. ResNet, along with Housing and Dining Hospitality and Time Warner Cable, provides you with a network connection primarily via Ethernet (wireless is provided in the common area of the dorm). The data connection in your room gives you direct access to the Internet from your personal network devices. 

Q: What does ResNet cost?
A: ResNet services will be included in your conference registration. No additional charges are required. 

Q: Who can connect?
A: All conference guests are wired for data connections. Most residential halls have ResNet wireless access points as well.

Q: How do I get connected?
A: Since most computers are set up with the default configuration settings to work right away, simply plug your network cable in and register your connection. If you run into problems, check out our FAQ and troubleshooting sections. This documentation also has information about how to check e-mail and information on commonly used e-mail applications. Make sure you are familiar with the Acceptable Use Policies listed at the beginning of the documentation.

Q: Is it possible to plug in more than one computer into the network?
A: You may have more than one device on the network (more than one IP) associated with your name, as long as you do not violate the Acceptable Use Policy. ResNet reserves the right to limit the number of IPs registered to you. Register every network device you use on the network. Please contact our office at (858) 534-2267 if you have any questions or have a unique circumstance.

Q: Should I worry about theft?

A: Laptops are stolen occasionally, but it's usually because the owner left their door wide open or left it at the library while getting a bite to eat. If you are careful, you probably won't have problems.

The UC San Diego Network

Q: Do I really need to register?
A: Yes. If you don't, you will not be able to connect to any website. If you are using the public "UCSD" (non residential) wireless network, see the directions here

Q: Does ResNet block P2P programs like BitTorrent and Limewire?
A: We do not block any Internet services at this time. Traffic may be prioritized, so during peak times, file sharing applications may seem blocked because they are moving so slowly. We do this to ensure each user has access to basic services, such as web browsing and checking email. If you have problem connecting to any site or using any type of service, please contact us!

Q: Are the IPs static or dynamic?
A: IP addresses are dynamic and are assigned by a DHCP server. The DHCP server keeps track of the unique hardware address on your network device and will assign you an IP address. If you are setting up a remote desktop service, we highly recommend using a DNS service. 

Wireless Networking

Q: What is wireless networking, and where on campus can I use it?
A: The wireless network is a high-speed Internet connection without physically plugging your computer into anything. Wireless campus coverage increases every year. Wireless is available in most ResNet areas, UCSD lecture halls and main campus areas. 

Wireless is provided to be used in the common room areas, and may not reach individual bedrooms. 

Q: How can I use it?
A: Follow the directions in the Getting Connected section. You must have a wireless LAN card using 802.11g/n standard.

Q: How fast the wireless connection?
A: For normal web browsing, checking e-mail, and Instant Messaging, wireless connection is comparable to wired connection speed. UC San Diego's wireless network is compatible with G/N wireless network cards, with each access point handling approximately 30 computers without noticeable degradation. The speed of your connection may drop as more users in your area connect.

Q: What if I get bad signal strength?
A: Call us for assistance. We may schedule an appointment with you to investigate the issue. 

Wireless is provided for the common room areas any may not work in your individual room.

Q: What does a wireless connection cost?
A: You do not need to pay to connect to the wireless network, but your computer must have a wireless Ethernet card installed or built in.

Q: Can I download large files?
A: Since wireless is shared, downloading large files slows down other connections. In addition, interference could cause you to lose your connection during the download.

Q: Can I buy and install my own wireless access point?
A: Setting up a wireless access point on your own is a violation of the ResNet Acceptable Use Policy

Q: Why is my wireless connection disrupted more often than my wired connection?
A: Many factors — including large metal objects, trees, cordless phones or microwave ovens operating in the same 2.4 GHz frequency range, and multiple users connected to the same access point and sharing the bandwidth — can disrupt wireless connections.
The wireless network is not intended as a replacement for the wired network. If you use a machine in a fixed location, we recommend that you use a traditional wired Ethernet connection.

Q: Where can I get more wireless networking information?
A: You can get more info on the UC San Diego Wireless Network website.
