If you've been through the steps in the
Getting Connected Guide but your residence hall networking connection is
still not working, here are some steps to try before you call the Office of Information Technology (OIT)
Help Desk.
First, try connecting your computer's ethernet cable to
another data jack, if one is available.
- Did the connection start working?
- If so, the first data jack has a problem. Please contact the
Resident Life Information Services Unit on (301) 314-DATA
Next, try connecting your computer to the data jack using a
different ethernet cable.
- Did the connection start working?
- If so, the original ethernet cable is bad. Otherwise:
Is there a flashing green or yellow light on your computer
near the computer's ethernet port?
- Look for a very small green or yellow LED near the computer's ethernet
port. If the lamp is there, is it lit?
- If present, but is completely dark, contact your computer's
manufacturer.
If the LED lamp is lit, or is flashing, use
these instructions to check the IP address
that your computer is using to communicate.
- Is the address all zeroes, or is it blank or does it begin
with 169.254?
- Re-check your network settings, then contact the
OIT Help Desk
if the problem persists.
- Does the address begin with 129.2 or 128.8?
- Contact the OIT Help Desk .
- Does the address begin with 192.168?
- Contact the OIT Help Desk .
- Does the address begin with 10?
- The computer is not registered on the Residence Hall Network. Please
use the registration system
