General ResNet Information

Q: What is ResNet?
A: 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 ACMS that provides support for students with network and/or computer questions or problems. Using presentations, our website, information tables, and written material, the ResNet staff works with the residence staff at each college to keep students informed about network related issues and help them become more computer savvy.

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

Q: Who can connect?
A: All conference guests and on-campus residents, including Warren Graduate housing and Coast Apartments, 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 get a Macintosh or a PC?
A: Both types of computers are supported by ResNet. If you have used one type of computer before and you are satisfied with it, we recommend that you go with the same type again.

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. 

The ResNet Program

Q: What is an RCC?
A: RCCs are Residential Computing Consultants. RCCs are students who are here to help you with your computer and network concerns.

Q: How much does all this cost?
A: ResNet is free to those living on-campus. All costs associated with services provided by ResNet are included in your housing fees.

Q: Are the RCCs certified or do they have any contracts with the manufacturers to do warranty certified work?
A: RCCs do not have contracts with the manufacturers to do warranty certified work, but most computer manufacturers will allow the case to be opened (and the seal broken) for the installation of simple hardware replacement (RAM, hard drive), depending on the computer manufacture.

Q: How can I sign up for an appointment?
A: If you are experiencing a network or computer related problem, call (858) 534-2267. We will first try to troubleshoot your problem over the phone. If we determine that you need an appointment, we will schedule you for the next available slot. Due to the high volume of calls during the first few weeks of each quarter, there may be up to a 5 day wait on appointments.

Q: Do RCCs get paid or is it volunteer work? How do I become an RCC?
A: RCCs are employees of UC San Diego and are paid hourly. Click here for more information. 

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: Only areas where wireless is not provided by ResNet (Coast Graduate Housing) can a personal wireless access point be installed. You will be responsible for all traffic going through your device. You must contact ResNet first. 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.

Maintenance for Mac Computers

Q: How can I make my Mac work the way it should if it is having problems?
A: For Mac OS X, run the Disk Utility (in the Utilities folder).

Q: How do I check what OS version I am running?
A: Click on the apple in the top left corner and select About This Computer.

Q: How do I boot from a Macintosh OS CD?
A: Insert the OS CD in your computer and hold the "c" key on your keyboard while the computer starts up.

Q: I want a fresh install of the OS. What can I do?
A: Boot with Macintosh OS CD, run Disk Utlity, and repair all the problems it finds. Then look for the utilities on the CD that will walk you through installing a fresh copy of the OS to your computer. Make sure you use the OS CD that came with your computer. Certain Apple computers will only work with certain versions of the OS. ResNet can assist you with this process. 

Maintenance for Windows Computers

Q: How can I make my computer boot up faster?
A: Having fewer programs start up when the computer first boots will increase speed.

  1. Click on Start (or the Windows logo), then Run, type in "msconfig" (without the quotes) and then click on the Startup tab.
  2. Check the list for the programs and files that automatically start when the computer starts up.
  3. Unchecking programs you don't need immediately. A few files need to be started with Windows, so only uncheck programs that you're familiar with

Q: My hard drive is full. What can I get rid of to free up more space?
A: Uninstalling some programs from your hard drive will give you more space. Keep in mind that once a program is removed, it can never be used again unless you reinstall it again.

Go to Start (or the Windows logo), then Settings, then Control Panel and on Add/Remove Programs. Remove any programs that you don't use or need from the list.
