�鶹��Ƶ Wireless Network

2011-06-22T14:15:23Z

Rander10: /* Connecting to the wireless network */

�鶹��Ƶ began a wireless [[network]] back in 2001. The plan has expanded to cover most of the College's indoor spaces, and many outdoor spaces. Intended as a convenience, the wireless network connects over 900 unique users a day to the [[Internet]].

==Wireless locations on campus==
Nearly all locations on campus are covered by the �鶹��Ƶ wireless network, with a few exceptions. All academic, residence and administrative buildings on campus have wireless coverage with the exception of:<br>
*Schaefer Fine Arts/Art (some areas)
*Schaefer Fine Arts/Music (some areas)
*Physical Plant Offices
You may experience limited connectivity or poor connectivity depending on your location within a building. If you would like to request additional wireless routers be added to a building or location, please email [mailto:wireless@gustavus.edu wireless@gustavus.edu]. Most outdoor areas within the ring road are also covered by the �鶹��Ƶ wireless network.

==Wireless in the residence halls==
The �鶹��Ƶ wireless network is available in all the campus [[residence halls]]. '''The wireless network is a convenience, and not a replacement for the wired network.''' The wired network is also available in every campus residence hall with one port per pillow. If you need more wired ports in your room, you may check out a [[switch]] from the [[Technology_Helpline]] to use during the year.

The wired network is faster and more reliable than the wireless network and intended to be the primary network in the Residence Halls.

==Connecting to the wireless network==
The use of the �鶹��Ƶ Wireless network requires a one time, web based registration, per academic year. Full access is limited to users with a �鶹��Ƶ e-mail username and password. Limited access is available for guests of the college.

To begin registration, launch a web browser ([[Firefox]], [[Internet Explorer]] or [[Safari]]) from a wireless zone with your wireless card enabled. Your web browser will redirect you to a series of registration pages. If your web browser does not redirect you and an error message appears, go to the page greg.gac.edu. You must be connected to [[GACwireless]]. Follow the prompts.

For more information about our registration process, please see [[Computer registration]] or [[Who is GReg and why do I need to know him%3F]]

==Problems with wireless==
The �鶹��Ƶ wireless network is slower and less reliable than the �鶹��Ƶ wired network. The wireless network is a shared resource, with all the wireless devices sharing the bandwidth.

The �鶹��Ƶ wireless network is not secure. As always, please verity that you using secure settings when sending email, and secure web sites for any financial transactions.

Many different devices can cause interferance with wireless signals. These devices may include:
*2.4 Ghz cordless phones
*personally owned wireless routers
*microwave ovens

If you are having trouble using the wireless network, please contact the Technology Helpline at x6111 or email [mailto:wireless@gustavus.edu wireless@gustavus.edu] or plug in and use a wired connection.

==Guest access==
Guests of the College are allowed limited access to the Wireless network through a web based registration process. Wireless access is available across campus, and wired access is available in the Residence Halls.

To begin registration, launch a web browser ([[Firefox]], [[Internet Explorer]] or [[Safari]]) from a wireless zone with your wireless card enabled. Your web browser will redirect you to a series of registration pages. Guests must be connected to the [[GustieGuest]] wireless network. Follow the prompts.

For more information about our registration process please see [[Computer registration]] or [[Who is GReg and why do I need to know him%3F]]

==Troubleshooting wireless connections==
If you are having trouble using the wireless network
*try moving to a location where you know the signal is strong (Olin Hall Computer Lab or the Library).
*verify that your network card is turned on and receiving a signal (using your card manager software or control panel).
*make sure others around you are able to receive a signal. If you have a location that is getting a poor signal, email [mailto:wireless@gustavus.edu wireless@gustavus.edu] and request additional access points be installed.
*contact the Technology Helpline (x6111) or [mailto:helpline@gustavus.edu helpline@gustavus.edu] for assistance.
*plug in with an Ethernet cable to a network port, until you get your wireless working.

Adobe Photoshop

'''Adobe Photoshop''' is [[software]] written by Adobe for creating and editing image files. It is also the program used at �鶹��Ƶ for importing images from scanner workstations, which can be found in numerous labs throughout campus. Adobe Photoshop CS5 is the most recent version of Photoshop and is currently the one in use at �鶹��Ƶ.

<div class="clearer"></div>
==Resizing images==
<video width="320" height="240" class="boxright">Resizing_images_in_Photoshop.flv</video>
To resize an image:
# Go to the '''Image''' menu and choose '''Image size...'''
# A box will appear in which you may choose new dimensions of the image.

The image will automatically scale, meaning that if you enter a new width the height will automatically change according to scale.

'''Note:''' The Adobe CS5 looks a little bit different than the version depicted in the video to the right, however the procedure works exactly the same.

==Scanning Documents==

Use Photoshop to scan pictures, documents, or slides. Note that slides usually require an additional adapter for the scanner, ask the lab attendant where the scanner is located if you would like to you a slide a adapter.

At this time scans can only be directly imported into Photoshop on Windows machines. If you are looking to edit a scan in Photoshop using Mac OSX, press the scan button on the machine and scan the image using the Image Capture software that will automatically pop up. The image of the scan will then be saved in your documents. Then load Photoshop and go to open --> documents and select the image you just scanned.

To scan a document to Photoshop using Windows:

1. Choose File > Import > WIA Support.
2. Choose a destination on your computer for saving your image files. (Generally choose "Documents" unless saving to a flash drive or other device)
3. Click Start.
4. Make sure that Open Acquired Images in Photoshop is selected. If you have a large number of images to import, or if you want to edit the images at a later time, deselect it.
5. Make sure that Unique Subfolder is selected if you want to save the imported images directly into a folder whose name is the current date.
6. Select the scanner that you want to use. The scanners in most labs are Epson 4870.
7. Choose the kind of image you want to scan:

Color Picture
Uses the default settings for scanning color images.

Grayscale Picture
Uses the default settings for scanning grayscale images.

Black And White Picture or Text
Uses the default settings.

Adjust The Quality Of The Scanned Picture
Uses custom settings.

After the settings are all correct, hit scan and an image of the item you are scanning should appear in a window in Adobe Photoshop, from here make any cropping or image size changes you would like to make and then go ahead and save the picture. Photoshop usually defaults saved documents to the .psd format, make sure you change this if you are intending on using the image outside of photoshop, common formats for images include .jpg, .bmp (both lower quality), and .tiff or .png (usually higher quality, but larger files).

==Use the Filter Gallery==

[[Image:OhlePaintDaubs.jpg|right|400px| President Ohle with the Paint Daubs Filter applied.]]

To quickly add a creative twist to any image you can use the Filter Gallery, introduced in Photoshop CS3, and used ever since. Before editing an image always remember to create a backup copy before you start so as to not lose any data. To use the filter gallery open the image you wish to edit in Photoshop and then go Filter-->Filter Gallery. Here you are presented with a wide array of filters to apply to your image. Choose which filter you wish to use, tweak the levels on the right side of the window until you are satisfied with the image, then click okay. Again, make sure you pay close attention to the format of the image when you save, .psd is only necessary when you wish to edit the photo in Photoshop again.
