East Campus Cable Modem Setup Overview

Steps to Set Up Your Modem

  1. Connect your cable modem to the cable outlet at the wall with a coaxial patch cable.
  2. Power on the modem, and give it a few minutes to boot. Verify that the “online” LED is illuminated. This LED is usually indicated with a globe icon.
  3. Connect your router or computer to the modem using an ethernet patch cable.
  4. Using a device connected to your router via Wi-Fi, or using a computer directly connected to your modem, open a browser such as Firefox and navigate to cablereg.csumb.edu. Please be patient as this page may take a few minutes to load.
  5. Students, staff, and faculty should log in with your CSUMB username and password. For non-CSUMB community partners, please use the campus partner account provided by Greystar.  After logging in, fill out the online form and click submit. The cable modem will reboot and when it comes back up, it will be online and provide Internet service to connected devices.

Recommended Cable Modems

An Arris DOCSIS 3.0 or higher cable modem is required and available online or locally at Best Buy. The Arris SB6190 or SB8200 are the standard for stand-alone modems which require a separate wireless router.  Please ensure that any router used with the stand-alone modem supports "Dual band concurrent AC wireless."  For an "All in One" modem with a built-in wireless router, Arris SGB10, SBG8300, or S33 are good options, with the SBG10 offering the best value. 

Note: We do not recommend using the Arris 8200v3 - there is a compatibility issue with this generation model and our cable modem system. Double check your box for product information before you buy. 

Please Note: While you can purchase other brands of DOCSIS 3.0 compliant modems, we currently only recommend and support modems manufactured by Arris. 

Any CableLabs certified DOCSIS 3.0 cable modem should work on the East Campus cable system. The following are likely to experience problems and are unsupported:

  • Used cable modems that came from another system.
  • Cable modems purchased online from discount vendors.
  • Older generations of modems which are DOCSIS 2.0 or lower.
  • Modems used with other services or carriers such as Comcast

We do not set up or provide technical assistance with home wired/wireless networks, or personal computers and other home network devices.

Wireless Routers in East Campus

CSUMB does not provide wireless service on East Campus, however, residents are welcome to set up their own personal wireless network.  For assistance setting up home network routers, users are encouraged to contact the manufacturer of the device.

Wireless Router Tips

Due to the densely populated nature of East Campus, wireless interference from neighbors is a common and frustrating issue for many users. Here are some tips to make wireless video streaming more reliable:

  • Purchase a modern wireless router that is “dual-band,” and can operate both on 2.4gHz and 5.8gHz bands.
  • Connect your devices to the 5.8gHz SSID. The 2.4gHz SSID is often shown with higher signal strength, but the signal strength is not always an accurate indication of signal health.
  • On the 2.4gHz band, there are only 3 non-interfering channels. 5.8gHz band has dozens of channels available, and most modern routers are capable of changing channels to avoid interference. This makes the likelihood of enjoying streaming video over wireless without interruption much higher.


  • Most routers come pre-configured with encryption enabled. While it is a good idea to change the wireless password to be easier to remember, it is never a good idea to disable wireless security for the sake of convenience.

IT does not set up or provide technical assistance with home wireless networks.  Users are encouraged to contact the router manufacturer for support on configuration and device issues.
