Network Access

Enjoy your high-speed wired connection

Residential Computing ensures sure that students living in the residence halls and campus apartments have reliable network access through both wired, in-room connections and campus-provided Wi-Fi. We provide each resident with a high-speed wired connected at a network speed of up to 100 Mbps (requires an Ethernet cable). The AirBears2 wireless network is also available throughout the halls and most apartments (at University Village, Wi-Fi is currently available in common areas).

In-Room Connection

To connect to ResComp’s wired network by plugging in to an Ethernet port, you will need to register for service and add any devices you want to connect to your account. You'll be directed to a short registration process when you plug in your device.

While you can register multiple computers or devices, only one can be connected to the Internet at a time via Ethernet because each resident is allotted one IP address. If you want to use multiple devices simultaneously, you can connect to the Airbears2 wireless network.

Most rooms are equipped with as many Ethernet ports as there are residents, but some triples in the older buildings will require the addition of a mini switch to provide enough connections. ResComp will distribute mini switches to the rooms that require them in time for move-in. Please contact the Helpdesk if you find there are insufficient Ethernet ports in your room.

Wireless all around

Wi-Fi in the Residence Halls


The AirBears2 network is available throughout the residence halls, with the exception of family housing apartments at University Village (where Wi-Fi is currently available in common spaces only).

To use AirBears2, you must have a valid CalNet ID (which most residents receive before coming to campus) and create an AirBears2 key. You can create your key here.

Learn more about connecting to AirBears2 with any of your devices by going to Berkeley's knowledge base or

Additional Wi-Fi Networks in the Residence Halls

AT&T Wi-Fi: Available throughout most residence hall locations. Current AT&T customers with a qualifying Internet, smartphone, or LaptopConnect plan can access the “attwifi” network where it is provided.

Eduroam: The eduroam network provides world-wide roaming access for the international research and education community. UC Berkeley faculty, staff, and students can use eduroam on campus and when visiting other participating institutions.

CalVisitor: Provides basic network access for visitors to campus who do not have a CalNet ID.

Wi-Fi Security and Policy

We strongly advise residents to consult with ResComp about wireless security. Information sent over personal wireless networks is vulnerable to being compromised, and instructions on how to sufficiently secure your particular wireless router are not always widely available. RCCs are a great resource in this area and can offer help in person, by email, or over the phone.

Please note that personal wireless routers are not permitted in the residence halls where Wi-Fi is already provided. Their signals can cause interference, which disrupts and degrades network connectivity for everyone. More information is available in our Wi-Fi FAQ.

For residents of University Village where campus-provided Wi-Fi is not currently available, you may set up your own Wi-Fi network by purchasing a wireless router. You must configure your router to not interfere with the residence hall wireless network. Please keep in mind that you will be responsible for any network traffic that comes from your wireless router.

You can purchase a router from a local electronics retailer or from an online vendor such as Amazon or Newegg. Depending on functionality, routers can run from $30 to over $100. Lower-cost routers are usually sufficient for most residents’ needs. If you want help setting up your wireless router or have questions about which routers are recommended, we encourage you to contact ResComp for advice or assistance.

If you have any questions about wireless in the residence halls, please see our Wi-Fi FAQ or email

We offer support to residents during the Fall semester move-in to ensure all residents get connected, individual appointments for hands-on troubleshooting, and office hours in each unit's Academic Center for drop-in service (bring your laptop). In addition, RCCs are available by phone at (510) 642-HELP during business hours and can be reached any time by email.

Appointments are 45 minutes long No same-day appointments phone support available too! RCC appointments are scheduled in 45 minute blocks, and RCCs are able to resolve most problems during that time.

Please note that same-day appointments cannot be scheduled - please check the office hours schedule for available drop-in service times.

ResComp services are included as part of your housing contract with UC Berkeley. Note that because ResComp services are paid for by housing fees, students not living in University-owned housing are not eligible for ResComp services.

Support During Move-In

During the Fall move-in period on campus, Residential Computing staff will be on site to assist with any network access or technology support issues students may have. RCCs will make rounds of each residence hall to offer help to those who request it. Schedules of RCC rounds will be provided to all students during move-in, along with more information about our services, policies, and resources.

ResComp Helpdesk

RCCs can be contacted over the phone at (510) 642-HELP Monday-Friday, 9am-6pm for quick questions or to request support. You can also reach ResComp any time by emailing our Helpdesk. Check our support page for more information.

    Cable TV FAQ

    Cables and Boxes
    1. What equipment do I need?

      You will need at least one cable-ready device to view channels above 2-13, such as a cable-ready television and/or a cable-ready DVD player or receiver. You will also need a coaxial cable to reach from your device to the cable outlet.

    2. Can I opt out of the residence hall cable TV service?

      As with other utilities provided in the residence halls and apartments (such as heating and water), there is no way to adjust the cost of cable TV for those residents who choose not to use it. The infrastructure would not allow disconnection of the cable upon request. We strive to keep the overall costs low for this service in order to minimally impact all residents.

    Signal Issues
    Confused signals?
    1. Why am I not getting a signal?

      Make sure that the TV has power and that the coaxial cable is properly connected at both ends. Check all wires for damage and replace any damaged wires. If you have additional components (such as a DVD player or gaming device), disconnect and try connecting the cable directly to the television. Check if your TV is cable-ready. If your television is not cable-ready, set it to channel 3 or 4, then switch channels through a cable-ready receiver.

    2. Why are channels 2-13 really fuzzy?

      This is usually the result of a bad coaxial cable. Try a newer coaxial cable to solve the problem. If the problem persists, make a Helpdesk appointment and an RCC can assist you.

    So many channels, so little time
    1. Will the channel line-up ever change to include any additional channels (e.g. Bravo, Disney, FX, Versus)?

      Adding certain channels to the existing line-up would cause the cable TV service to be dramatically more expensive, and ResComp wants to keep costs low for residents. For example, adding just one additional network could cost between $10,000 and $20,000 more per year. We want to avoid passing on such an additional cost to our customers.

    2. Why are some programming times listed 3 hours ahead in the TV guide?

      The satellite service provides east-coast-only feed to many channels in order to keep costs low. It would require twice as many signal paths and increase costs to allow both east and west coast satellite feeds.

    3. Can I subscribe to premium channels?

      Premium channels through the residence hall cable TV service are not available. The cost to provide the specialized infrastructure that would allow some residents to subscribe to premium channels is very high, and direct feedback from our customers over the last several years does not reflect a strong desire for this service.

    4. Will any channels be available in HD?

      The costs of providing HDTV have historically been high, but we are working to try and provide that service.
