Using Laptop Computers over the internet in HFA

There are currently three methods by which a user can connect his/her laptop computer to the internet in HFA.  NOTE: It is strongly recommended that any laptop user who connects his/her laptop computer to our network maintain an active program of virus scanning and checking. Any laptop found to be spreading or attempting to spread any virus will be removed from the network until such time as the laptop has been cleansed of said virus and no longer poses a hazard to the internet.

VISITORS: Visitors who wish to connect to the internet from HFA must
agree to abide by university computing policy.  

1) Wireless Access
Use the AirBears campus wireless network.  Select the AirBears network and start up a web browser such as Firefox, Safari or Internet Explorer.  You should be prompted to log in. University employees should authenticate using their CalNet ID and pass phrase.  Visitors may obtain a temporary guest AirBears account from Bill Boyd .  

2) Wired, Fixed IP address
Have a new ethernet connection installed in your office. This costs money and involves setting up an appointment with Campus Network Services. The availability of fixed addresses in the astro subnet is very limited.

For assistance with either of these, please contact Bill Boyd.

3) Wired, Dynamic IP address
Buy a small ethernet switch to put your workstation and laptop on and use DHCP to connect to our DHCP server. Please see Bill for assistance in configuration (do not install this device on your own). If you are unsure how to configure your laptop to use DHCP, please see Bill to get further assistance. Make sure the ethernet switch has the following features:

  • at least 10/100 Megabit/sec support (using UTP CAT5 ethernet cables)
  • an uplink port or auto-uplink capability
  • NO WIRELESS capability
  • two CAT5 UTP ethernet cables of the appropriate length

Note: Laptops configured in this manner must share the bandwidth through the firewall on the DHCP server. If you need to have a full 100 megabit/sec bandwidth connection, use choice 2) instead. Some users may need to contact Bill Boyd to get help configuring their system.
