Many factors can affect your computer's performance on the residential network. Please
follow this checklist to make sure your computer is configured for optimal performance.
Make sure your computer is not infected with a virus and that the antivirus software
is up to date with the latest antivirus data files.
Check whether your computer is infected with spyware. Spyware is the most common cause
of poor network performance on the residential network. You should download and install
one or more anti-spyware programs, then run them regularly to remove spyware from
your computer.
For the best performance on Chapman's network, you should use an Ethernet cable, which
can be purchased at Chapman's bookstore or any electronics store.
Wireless Network Performance
Most of the rooms and public areas of Chapman's residence halls are covered by the
campus wireless 802.11 b/g network. Your computer must be properly configured to access
the Chapman wireless network. Please contact the Service Desk for assistance with
configuring your computer for connecting to the Chapman wireless network.
Several factors can affect the performance of the wireless network, such as:
- Personally owned firewall/router devices. Many students bring their own firewalls
and routers to campus. These routers can become "rogue" DHCP servers and assign invalid
IP addresses to other student computers, preventing them from accessing the Internet.
These "rogue" devices will interfere with Chapman students trying to connect to Chapman’s
wireless network. Chapman does not allow personally owned firewalls or routers to
be used on the network. Students are subject to disciplinary action by the Student
Conduct Committee if they violate the policy of installing personal firewall/routers.
- Personally owned wireless access nodes. Many students bring their own wireless access
nodes to campus and connect them to our wired network. These "rogue" wireless access
nodes prevent other students from connecting to the Chapman network. If you are having
trouble connecting to Chapman’s wireless network, please call the Service Desk at
(714) 997-6600. Students are subject to disciplinary action by the Student Conduct
Committee if they violate the policy of installing personal access points and personal
gateways.
- Personally owned wireless printers. Wireless printers act as "rogue" wireless access
points, preventing other students from connecting to the Chapman network. Also, a
wireless printer will allow any student to use your printer at any time of day. To
use any printer in your room, you need to buy a USB cable and connect the printer
to your computer via USB.
- Bridged network interfaces. Some students have, perhaps by accident, configured their
computers to bridge the Ethernet and wireless interfaces. This interferes with connectivity.
If you use the wireless interface on your computer, please make sure that it is not
bridged with the Ethernet interface.
- 2.4 GHz cordless phones. The wireless 802.11b/g network operates at 2.4 GHz. Cordless
phones operating at 2.4 GHz can interfere with wireless network signals. Older cordless
phones operating at 900 MHz and newer cordless phones operating at 5.8 GHz do not
interfere with the wireless data network. 900 MHz and 5.8 GHz cordless phones are
permitted, but 2.4GHz cordless phones are prohibited in the residence halls because
they can interfere with the wireless network.
- Microwave Ovens. These ovens also operate at 2.4 GHz and can interfere with wireless
network signals. Microwave ovens are prohibited except for the ones in the "micro
fridge" units that you can rent from the Housing Office.
