*DHCP must be turned off so that the router is not assigning private IP addresses to its computers. The "router" part of the router or Airport must be disabled so that it functions only as a wireless access point, this is also called "Bridge" mode.
 
*What we want to avoid is a situation where the router acts as a DHCP server, taking the place of Middlebury's DHCP server. Computers at Middlebury College need to have addresses assigned by the Middlebury College DHCP server for a number of reasons.

Home networking devices, such as DSL or cable-modem devices, home routers, wireless routers and wireless access points, etc., can cause serious disruption of campus network services. The default, "out of the box" configurations of many of these are such that, if connected directly into the campus network, they can disable network access for an entire subnet. No such device may be connected to the campus network without prior consultation and approval of LIS network management staff. Discovery of unauthorized devices may result in immediate disconnection of network service. If a device is found to be disrupting network services, it will immediately be disconnected from the network while LIS staff members attempt to contact the owner.
  
Wireless Access Point Configuration Guidelines

#WAP delivered to helpdesk (w/ documentation, by owner, do not check devices in, configure them with the owner –see below)

##(note that Apple AirPort WAPs should be configure with Apple's AirPort Setup Assistant or AirPort Utility - these can be installed with the CD that came with the WAP or by using the Helpdesk iMac which has them in the /Applications/Utilities folder)
 
#Connect to WAP w/ HD computer (via Ethernet cable – use switch ports, NOT internet, uplink or WAN port)
 
#Browse to the WAP – http://ip_address_of_wap (ipconfig from computer will provide default gateway = WAP address )
 
##Logging in will depend on make/model of the device, use the documentation or try a Google search to find default username/password
 
##The IP address of the WAP is usually (but not always) 192.168.1.1
 
#Configure WAP:
 
##Disable DHCP (note that once this happens you will need to RESET the AP to configure it again)
 
##Set SSID to username
 
##Enable WEP or WPA (user sets password – can be shared)
 
##Admin Password for WAP (user sets password – not to be shared)
 
#Test WAP (connect WAP to network jack, connect a computer wirelessly, confirm 140.233.x.x IP address for computer)
 
#Tape Label on WAP (SSID=username; IP Address of WAP – from step 3; and tape over WAN/uplink port)
 
  
If for some reason you need to reset the AP, look for a small button labeled "RESET". Note that resetting the AP will usually undo all the steps that were done before, including erasing any passwords that were set. Consult Google or the AP's documentation for more details on how to reset an AP.

#Check network settings to ensure that computer is getting connectivity via Eth port, but the address should be 192... or 169..., not 140.233.... That means that the Airport router is working and isn't connected to the wider internet.

[[Category:Public Search]]
#Open utilities -&gt; Airport Setup Utility (CD in Helpdesk if not auto installed). ASU should detect your Airport after some searching.
 
#Enter "Manual Setup" and configure the Airport accordingly: register according to MAC address, DHCP should be off...
 
 
 
#Unplug power from the Airport, plug in Eth from WAN network, plug back in. If settings are correct, when the airport reinitializes, it should get a 140.233 address and the computer connected to it should also get a 140.233 address (while connected by wire).
 
 
 
== Troubleshooting Aruba Wireless Access Points ==
 
 
 
The College provides wireless network in a large portion of the campus. The wireless coverage depends on the wireles routers that are being installed. The College uses '''Aruba Wireless Access Points'''. They are white in color and have a large gray number on the front, indicating the model. Usually they are set up to obtain electricity, configuration, and network connection, all through the wired ethernet port (so you won't see a power cable). When reporting a problem with an Aruba router, please let the Helpdesk know:
 
 
 
*where the device is location (building and room)
 
*what color is it
 
*what's the model number
 
*which lights are on, if any, and are any of the lights solid on, or blinking.
 
 
 
Here are some diagnostic notes:
 
 
 
* The first (leftmost) LED light is the power indicator (PWR). The second LED&nbsp;light is the ethernet indicator (ENET ). The last (rightmost) LED&nbsp;light is the wireless signal indicator (WLAN).
 
* If all lights are off, then the router is recieving no power, nor ethernet, and is therefore not broadcasting wireless signal.
 
* If the PWR light is on, it means the unit is receiveing power. If the PWR&nbsp;light is blinking, there's a power problem (check the power cable, if there is one, else check the ethernet cable -- these units can receive power AND ethernet through the ethernet cable).
 
* If the ENET light is on or blinking, it means the unit is receiving ethernet signal. If the ENET light is off, there's a problem with the network connection (check the ethernet cable).
 
* If the WLAN light is on it means that the unit is broadcasting wireless. If the WLAN&nbsp;light is blinking or off, there may be a problem with the

Personal Routers (of any type):

Personal routers of any type are prohibited on the Middlebury Campus network.


According to the handbook  :

Home networking devices, such as DSL or cable-modem devices, home routers, wireless routers and wireless access points, etc., can cause serious disruption of campus network services. The default, "out of the box" configurations of many of these are such that, if connected directly into the campus network, they can disable network access for an entire subnet. No such device may be connected to the campus network without prior consultation and approval of LIS network management staff. Discovery of unauthorized devices may result in immediate disconnection of network service. If a device is found to be disrupting network services, it will immediately be disconnected from the network while LIS staff members attempt to contact the owner.
