Frequently Asked Questions

General ResNet Information

What is ResNet?

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

ResNet is also a group within the Information Technology Service Desk that provides support for students with network- and/or computer-related questions or problems. Through presentations, our website, information tables, and written materials, the ResNet staff works to keep students informed about network related issues and help them become more computer savvy.

What does ResNet provide?

ResNet provides you with an Ethernet data connection in your bedroom and WiFi and bulk cable TV service in your suite's common room. We also provide technical support for these services.

Does ResNet provide warranty certified support?

ResNet staff will help you with software troubleshooting, but they we do not have contracts with the manufacturers to do warranty certified work.

What does ResNet cost?

All costs associated with services provided by ResNet are included in your housing fees. There are no additional fees or charges.

Who can connect?

All UC San Diego affiliates are able to login using their Active Directory information. Guests of the University are also able to create a guest login account.

How do I get connected?

Since most computers are set up with default configuration settings that work right away, simply plug in your network cable and register your connection, or connect to the encrypted wireless using your UC San Diego AD username and password.

Is it possible to plug in more than one computer into the network?

You may have more than one device on the network and more than one IP address 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.

Should I get a Macintosh or a PC?

Both types of computers are supported by ResNet, and while they are functionally the same, some programs will only work exclusively on PC or Mac. We recommend you spend some time researching your purchase and choose a computer that runs the programs you wish to use (for example, you will need a Macintosh computer if you want to run GarageBand, and you will need a PC if you want to run most video games) and fits your budget.

The UC San Diego Network

Do I really need to register?

Yes. If you don't register, you will not be able to connect to most websites. If you are using the public "UCSD" (non residential) wireless network, see directions here

Does ResNet block P2P programs like BitTorrent and BearShare?

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 like web browsing and email. If you have problem connecting to any site or using any type of service, please contact us!

Are the IPs static or dynamic?

IP addresses are dynamic and are assigned by a DHCP server. The DHCP server keeps track of the unique hardware address on your networked 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

Where is WiFi available on campus?

Wireless is available in the common suite areas of all ResNet locations. On the main campus, wireless is available in buildings and lecture halls. Due to radio interference issues, wireless is not guaranteed in the bedrooms.

How can I use it?

Follow the directions in the Getting Connected section. Your device must support 802.11 g/n standards on either the 2.4 or 5 GHz bands.

Is the WiFi on campus harmful?

No, the WiFi used on campus is completely harmless. More information can be found here: http://blink.ucsd.edu/safety/radiation/radfreq.html

How fast the wireless connection?

For normal web browsing, checking e-mail, and watching standard definition video, the wireless connection should be sufficient for your needs. UC San Diego's wireless network is compatible with G/N wireless network cards, with each access point handling approximately 15-25 computers without noticeable degradation. The speed of your connection may drop as more users in your area connect, or if multiple users are performing high-bandwidth activities, such as playing games or streaming HD video.

What if I get bad signal strength?

Wireless is provided for the common room areas and may not work in your individual room. Call us for assistance. 

Can I download large files?

Since wireless is shared, downloading large files slows other connections. As a courtesy to others, we ask that you use the wired connection for large file transfers.

Can I buy and install my own wireless access point?

Only areas where wireless is not provided by ResNet (Coast Graduate Housing) can a personal wireless access point be installed. In other areas, setting up a wireless access point on your own is a violation of the ResNet Acceptable Use Policy

Why is my wireless connection disrupted more often than my wired connection?

WiFi is a radio standard, and radio standards are much more subject to interference than direct-attach copper Ethernet. Many other devices operate in the 2.4 GHz frequency range, such as Bluetooth devices and microwave overs, and these devices can disrupt users using the 2.4 Ghz spectrum. In addition, only so much bandwidth is available for radio users, so multiple users connected to the same access point can cause slow downs and interruptions.

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.
