Frequently Asked Questions

General ResNet Information

What is ResNet?

ResNet (short for Residential Networking) is the physical network that provides each undergraduate student living in the on-campus housing with wireless or wired network connections.  

ResNet is also a group within the Information Technology (ITS) Service Desk that provides network and computer related support for students.

What does ResNet provide?

ResNet provides you with a network connection in your living areas and cable TV service in your suite or apartment's common room.  We also provide technical support for these services.

  • In most residential areas, wireless access is available in the common area and wired (Ethernet) connections are available in the bedrooms. 
  • In wireless only areas, wireless access is available throughout most areas of the suite/apartment (including common areas and bedrooms).  Wireless only areas include The Village, Eleanor Roosevelt College (ERC), and Marshall Upper apartments.  These areas do not have wired connection to accommodate the expanded wireless coverage.

Does ResNet provide warranty certified support?

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

What does ResNet cost?

All costs for the services provided by ResNet are included in your student 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 (AD) information.  Your Active Directory login is usually the first part of your UCSD email address (before "@ucsd.edu") and the email password.  Guests of the university are 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 connect to the encrypted wireless using your UC San Diego AD username & password or plug in your Ethernet network cable.

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 Mac 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 Mac 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?

On the main campus, wireless is available in buildings and lecture halls.  In all undergraduate residential areas, wireless is available in the common rooms.  

  • In most residential areas, wireless is only provided in the common room and wired (Ethernet) connections are available in the bedrooms. 
  • The following residential areas are now wireless only: The Village, Eleanor Roosevelt College (ERC), and Marshall Uppers.  In these areas, wireless access is available throughout most of the suite/apartment (including common areas and bedrooms) and do not have wired connections. 

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 is 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?

If you have bad signal strength in your living areas, contact us for assistance.  Note: Wireless is only guaranteed in the common room of all residential areas EXCEPT for The Village, Eleanor Roosevelt College (ERC), and Marshall Uppers apartments.  These areas should have wireless access throughout both the common areas and the bedrooms.

Can I buy and install my own wireless access point?

Personal wireless routers are not allowed in campus residences due to interference on UC San Diego wireless equipment. As stated in the Acceptable Use Policy the installation unauthorized networking equipment, such as wireless routers or network extenders, is strictly prohibited. 

Can I unplug or move existing wireless access points?

No. Disconnecting or moving networking equipment in campus residences will take the wireless access point off-line and impair the function of the network. This will affect all network connections in the area and will be a disruption to other residents. This action is prohibited as stated in the Acceptable Use Policy.

Is the ResNet WiFi getting upgraded?

Yes, HDH and ResNet are currently in the process of transitioning the ResNet networks over to a wireless-only infrastructure. Areas are being upgraded with the installation of additional wireless access points in order to have better coverage throughout the residences. In these areas, due to the installation of additional access points, residents will not have access to Ethernet as these ports need to be requisitioned for the new wireless equipment. Please note that the list of locations in each section may change quarterly.
