Wireless Access Guide

Wireless internet access is available around campus.
What is a wireless LAN and how does it work?
A Wireless LAN (WLAN) is a system that uses radio frequencies (RF) to allow transmission of information without a physical connection. Client devices, typically laptops, tablets, or smartphones connect through a physical device called an access point to gain network access.
What do I need to connect? 
The only hardware that is necessary is a laptop/notebook, smartphone or tablet with a IEEE 802.11b/g, IEEE 802.11b/g/n or IEEE 802.11b/g n/ac wireless card. The wireless network supports both 2.4Ghz and 5Ghz radio frequencies.

The card may be either:
  • Embedded/internal/built-in (typical in modern devices)
  • External (typical in older devices)
Is any configuration necessary?
Not much, just these few things:-
1. Enable/Turn on the wireless radio card in your device (if your device is wireless has a built-in radio) or insert a wireless USB adapter into a USB slot of the device (if an external card is required).
2. If necessary, set the TCP/IP settings of the wireless connection to both obtain an IP address automatically and obtain DNS server address automatically.
How do I connect?
 The  wireless  network  is  designed  such  that  once  the  client  device  is  configured correctly it will see the wireless network. In the list of available wireless networks select the campus wireless network (SSID) named CaveHill-Open. Once the connection has been established, you will be able to browse the internet.  
NB Currently the wireless network does not connect to the internal campus network resources such as the printing services or the main library’s databases. However, cloud services such as E-Learning, CHOL, The Student Portal and Email are accessible via the campus wireless network.

Troubleshooting Tips
 A few things can be checked to solve or at least identify any problems.
1. First of all, review the configuration steps.  Incorrect configurations are very common sources of connectivity problems. Please ensure that:-
(i) The radio (embedded/built-in) is turned on or the wireless client adapter
(external) is enabled.
(ii) The Wireless connection is enabled. Many times only the Ethernet connection is enabled so no wireless connection can be established.
NB These two are the most common misconfigurations.
2. Type the command ipconfig at the command prompt. The IP address of the wireless connection should be where yy ranges from 1 to 31 and xxx ranges from 1 to 254. If the IP address is not in that range the device is not connected to the campus wireless network. If the device is not connected, it may be physically out of the range of the wireless network. Try moving closer to the wireless connection device (access point) and type ipconfig /renew.
3. Ensure that you are connected to the CaveHill-Open wireless network. Alternatively said, ensure that the SSID of the wireless network you are connecting to is CaveHill-Open. ALL campus wireless “hot spots” have CaveHill-Open as their SSID.
Still having problems?
 If problems are experienced while using or attempting to use the wireless service, send an email to describing the problem in detail (paste the error message in your email if possible).
Also, include your personal details (name, student ID etc) and your location at the time of the error.
Any precautions? 
The campus wireless network is a public  network, this means that no authentication is required to access the network and there is no security  on the network. It is strongly advised to take the below measures to protect your device(s) from attacks and viruses:-
1. Install and use Anti-Virus Software on the device and most importantly ensure that it is frequently updated with the latest virus definitions. An antivirus program identifies and removes computer viruses found in memory, on storage media, or in incoming files.
2. Install and use a Personal Firewall. A Personal Firewall is a software program that detects and protects the device and its data from unauthorized intrusions by constantly monitoring all transmission to and from it.
Glossary of Technical Terms 
Access point
A  WLAN transceiver that  uses  radio  waves  to  connect wireless client devices to a wired network.
IP Address
An  IP  Address  is  the  numerical  address  that  uniquely identifies a computer on a network.
Service Set Identifier or wireless network name. It is a unique  identifier  that  allows  a  client  to  recognise  one access point over another.
Wireless client adapter
Wireless card used to connect to the access point.
Wireless client utility
The programme (software) that manages the wireless client adapter (wireless card). If the wireless card is embedded/built-in then the client utility should already be on the device. In cases where an external card is used the client utility should be installed from the accompanying CD.
