Campus Manager and Resnet FAQ

What do I need in order to use the campus Ethernet network?

You will need a 10BaseT, 100BaseT, or 10/100BaseT Ethernet card. Our equipment will auto-negotiate to either 10 or 100 Mbps speeds dependent upon your network (Ethernet) card. You will also need the drivers that come with the card. These usually reside on a CD-ROM. (You may also need your Windows or other operating system CD or disks.)

What kind of cable do I need?

You will need an Ethernet cable. These cables come in various lengths and colors--typically blue, green, gray, or yellow, see Figure 1. They will have RJ-45 connectors (similar to a standard phone cable connector only larger; see Figure 2 ) on each end. These cables might also be referred to as Category 5 or Cat 5 (also Cat V) patch cables. The Lycoming College Bookstore located in the Wertz Student Center has both network cables and cards available for purchase as should any retail store that sells computer related equipment and supplies.

What is a network/Ethernet card?

An Ethernet network adapter (card) provides the interface for communication between a computer system and an Ethernet network. When determining which adapter to buy, make sure that it operates at speeds of 10 or 100 Mbps (or both, typically noted as 10/100 Mbps) on an Ethernet network and that it utilizes an RJ-45 connector. We recommend the purchase of either a 3Com or Netgear branded network card. Typically these will be internal adapters requiring removal of the computer's external cover for installation. External USB varieties are becoming increasingly popular and more widely available and do not require internal installation. However, these devices are dependent upon the availability and functionality of a USB port on the computer system.

What does an Ethernet connection look like on my computer and in the wall?

On a typical desktop computer system, the RJ-45 connector/port will look similar to a typical phone jack, only slightly larger (see Figure 3). The hardware configuration of this particular computer system includes a typical modem (labeled at bottom), as well as two (2) network cards. One card is typical of many newer Ethernet network cards. It provides one RJ-45 port (circled in red) and uses a standard Ethernet (or Cat 5) cable. Most adapters will have LNK (link) and ACT (activity) lights visible next to the RJ-45 port. You'll notice the RJ-45 adapter's indicator light is not as obvious (its the small square "dot" to the left of the port) as those on the wireless network adapter (recognizable by the attached antennae) installed in the expansion slot above it. On the wireless adapter, the lights are located just to the left of center on the card-one is amber and one is green.

Some desktop systems have what is known as an "on-board" or "integrated" network adapter, which is included on the system's motherboard itself. In this case, the RJ-45 port will often be in close proximity to the other system ports for the mouse, keyboard, USB, serials, etc (see Figure 4). In the case of laptops, notebooks, and other portables, the Ethernet adapter can also be integrated, as is the case with newer systems, but will often be in the form of a PC card (PCMCIA) and installed in a Type II slot. They typically connect to the network by means of a short cable adapter known as a dongle (see Figure 5). Some newer adapters, however, do not use dongles and are, appropriately enough, known as dongleless adapters (see Figure 6).

Which wall-jack do I plug the Ethernet cable into?

The Ethernet cable should be plugged into the Ethernet jack. The majority of the Ethernet jacks installed in the residence halls on campus are blue in color and in close proximity to the phone jacks, which are gray. Typically both the phone and Ethernet jacks will be visible on the same faceplate mounted to the wall box.

Will Ethernet work with any operating system (Windows XP, Vista, Windows 7, Linux/Unix, Mac OS, etc.)?

If the Ethernet adapter you purchased has drivers for your operating system and you have installed and properly configured the TCP/IP protocol (usually installed automatically and by default with the installation of a network adapter) as described for the Windows and Mac operating systems, you should be able to access the Internet via the campus Ethernet.

Can I use a Mac or a PC?

You can use either a Mac or a PC to access the campus Ethernet provided you have an Ethernet adapter properly installed and configured as well as the TCP/IP protocol.

How can I tell if my computer has Ethernet/network card installed already?

Refer to question 7 above for what to look for on your system to determine if you have a network card installed. Another quick way to check on a Windows machine is to go to the Control Panel and double-click on the System icon (see Figure 8a and 8b). For Windows XP, please note you may have to click the "Switch to Classic View" to find the System icon. (The image below shows Classic View with the option to "Switch to Category View".)

After double-clicking the System icon, a System Properties window will open. Select the Device Manager tab. (In Windows 2000, select the Hardware tab then click the Device Manager button as shown in Figure 9b.) In Device Manger, look for Network Adapters in the list that is displayed. If necessary, click on the "plus" sign beside Network Adapters to see what adapters the group contains. If your system has a network adapter installed, it should show up in this group. There will typically be a Dial-Up Adapter and perhaps several others. Any Ethernet adapters are usually identified with the word Ethernet (see Figure 9a and 9c).

While installing my Ethernet card, the Hardware Installation Wizard returned an error indicating that it could not find a file. Now what?

This error usually means that the PnP system that is a part of the Windows operating system needs certain files in order for the Ethernet card to function properly. These files should be located on the driver disk (typically a 3.5" floppy, but might be on a CD) supplied by the manufacturer with the Ethernet card or on the Windows 95x/Me/2000/XP CD. You should be able to insert the disk when prompted, change the "Copy Files From" or "Look in" field to the drive and/or directory containing the needed driver file(s) and complete the installation.

Occasionally Windows cannot detect the path to the proper driver file. When this happens, the system will continue to prompt you for the disk even though the disk is in the drive. If you are experiencing this situation: First check (once more) to verify that you have the disk or CD containing the driver files for you particular network card in the drive. If you do, assuming your drive is working and the disk is readable, you may have to specify the exact path to the file you need.

Use the Browse button if it's available in the installation window to browse the appropriate drive (floppy or CD) and look for a directory that matches your operating system-i.e. Win95, Win9x, WinMe, etc. (See Figure 10a and 10b. Note: Windows 95/98 drivers will occasionally work with later versions of Windows-Me, XP and 2000.) If a Browse button isn't available, you will have to browse the disk using Windows Explorer and write down the directory path-i.e. D:\Drivers\Win98-so you can manually type it into the "Copy Files From" or "Look In" fields when prompted.

If you have to use Windows Explorer, it may be necessary to cancel the installation process. If you can't get to your desktop to double-click on My Computer to open Windows Explorer, you will have to cancel the installation process to complete the system reboot in order to get to your desktop.

If you have to cancel the installation or you chose to "Skip" a file at any point during the installation process, you will need to rerun the installation to re-install the drivers for the Ethernet card. Canceling or skipping a file often results in a partial installation. In this case, the Ethernet card will be added to the "Other Devices" category, although not as a functioning device. To see if this has happened, open the Control Panel and double-click the System icon to open the System Properties windows. Click on the Device Manager tab. (Refer back to question 10, Figure 8a through Figure 9c for help opening Device Manager.) Other Devices is listed under the yellow question mark icon as shown in Figure 11. If the yellow question mark icon is not visible, there are no Other Devices installed. In this case, look for your Ethernet card under the Network Adapters category.

ODevices

Figure 11

Please note, a black on yellow exclamation point (for an example see Figure 11) or a red "X" (for an example see Figure 12) over the icon of an installed device displayed under Device Manager indicates a problem with the device and that it is not functioning properly. In this case, or in the case where the Ethernet card is installed under Other Devices, it is necessary to select and "remove" the device before attempting to reinstall it. Otherwise a duplicate device may be installed that can conflict with the first installation. After removing a device from Device Manager, you should be prompted to restart your system. If the Ethernet card is Plug and Play compatible, the system will detect it and start the installation wizard again during the system restart. If it is not Plug and Play compatible, go through the manual installation process for which instructions can usually be found in the documentation included with the Ethernet card.

I keep getting an error message about another device on the network using the same IP address. What do I do?

This error message will often occur when another user on the network has improperly configured their system with a static IP address rather than setting it to "Obtain an IP address automatically." (see Figure 15.) It can also occur when an end user's system is not releasing and renewing their IP address lease properly.

For XP, 7

  1. Click on the start menu
  2. Choose "Run"
  3. Type "command"
  4. Hit enter
  5. (This will bring up the command prompt window)
  6. Make sure you're at a plain c:\>prompt
  7. To get there, type "cd.." and hit enter until all subdirectories are gone
  8. At the c:\>prompt, type "ipconfig/release"
  9. Hit enter
  10. At the c:\>prompt, type "ipconfig/renew
  11. Hit enter
  12. This should renew the ip address

When reporting the problem, it is important to report the problem as an IP conflict. If possible, you should write down the exact wording of the error message, including all numbers and/or addresses listed. This information will aid the network technicians in resolving the problem.(see Figures 15a and 15b.)

I keep getting an error message that something has "...performed and illegal operation..." every time I try to open a particular application or perform a specific task. What do I do?

An "illegal operation" error is usually indicative of some form of resource conflict on the computer system. This can be either a hardware or software conflict. Often it is a case of multiple software applications attempting to use the same memory space, but can be related to other system resources as well. You will need the assistance of a qualified technician to resolve this type of error. It often involves identifying and removing conflicting software applications, but may require a complete system rebuild or reimaging to correct. Before taking that drastic a measure, however, review any recent changes to your system. Have you added new software applications, new hardware or changed system settings? Do you have an antivirus application running on your system with current virus definitions and you've preformed a recent complete system scan? Often if you can undo the change that was made, you can resolve the conflict. Otherwise, you should seek technical assistance from a knowledgeable source.
