Usually, in a school, even to access wireless, it is going to require an encrypted password. If you have "SO CALLED HACKERS" in your school saying they have penetrated the system, they are probably just all talk. I wouldn't be too concerned with your "IP Address" because it will be assigned a new one upon connection to the wireless system at school. The main number to be concerned with would be your MAC address which is harder to retrieve than any temporary IP.

Hello, You won't need to do anything. When the connection is made from your laptop to the wireless signal at school, an IP address will be assigned dynamically(automatically). Just turn it on and if it doesn't connect within 20-30 seconds, click start, control panel and then network connections. Follow directions and it will connect for you. Hope this helps, Good luck..

Acer Aspire 5733 Wireless connection lost


Check the wireless router and high-speed modem.

If the two are not powered on, or if the Ethernet cable connected the two is not completely inserted into both connection ports, you are unable to access the Internet on the Acer Aspire One laptop computer.


Activate the wireless Internet connection on the laptop computer.

Right-click the wireless icon on the desktop, then choose "Enable" from the pop-up menu.


Without activating the wireless receiver on the Acer Aspire One, the laptop is unable to detect any wireless network.


Select the appropriate network you wish to connect to.


Your computer may be attempting to connect to a different Internet connection, preventing you from access the network you desire. Right-click the wireless icon, select "Search for available wireless networks," then choose the network you want to access.


Restart the computer.


The system may have booted and failed to detect the wireless receiver. Restarting the computer corrects this issue.


hope this helps

CANNOT LOAD WIRELESS INTERNET


First you have to have the right equipment both the wireless modem or router and the hubs USB or other wise the adapters. Then you have to know the password key for your wireless connection. If you do not have one it is suggested you provide one to protect your privacy and keep others from draining your connection. "Private Network Important" Any machines you are allowing to join the network have to log in using the same WAP credentials or log in information. Once this is established you will be able to access your wireless connection with any computer that comes in to play using your connection. So make sure these are perfectly correct. Other than this contact your provider for assistance. I know that can be a pain since support these days are confined to high school or overseas folks answering questions.
Start with the main computer first. Set information up just the first and main machine. Then configure the rest of your devices with the same information you worked out with the main it has to be exact. I hope that you get this solved it can be frustrating. John

Cisco access point


Hi,
How to configure wireless access point using a laptop
Wireless technology makes connecting to the Internet possible from anywhere within the range of the network. Unfortunately, not all Internet-capable devices have wireless technology, and many still require an Ethernet port connection. If you have a laptop with a wireless card and an Internet connection, you can make the laptop a wireless access point and share that connection with other devices, whether your laptop runs a Windows or OSX operating system. Windows computers allow other devices to access the wireless network via a physical connection to the laptop, while OSX computers allow AirPort equipped devices to connect as well, creating a second wireless bubble for the network.

Instruction:
WINDOWS
1 Turn on the laptop and the device with which you will share the connection. Ensure the laptop's wireless card is turned on and you have an Internet connection.

2 Connect an Ethernet cord to the port on the laptop, and the other end to the receiving device. You need to make the connection first, or you will not be able to access the sharing options for the connection.

3 Open the list of network connections on the computer. In Windows 7 and Vista, access this list by typing "Network Connections" into the Start menu search bar and pressing "Enter." In Windows XP, click on "Network Connections" in the Network and Sharing Center section of the Control Panel.

4 Right click on the wireless connection and select "Properties," then navigate to the Sharing tab. This tab will not appear unless both devices are connected.

5 Check the box marked "Allow other network users to connect through this computer's Internet connection." Click "OK" to save the changes.
OSX
1 Click on the Apple menu and select "System Preferences." Click the "Sharing" option, then choose "Internet Sharing."

2 Select the Airport and wireless network in the "Share your connection from:" drop-down menu.

3
Select an output format for the connection in the "To computers using:" drop-down menu. Choose "Ethernet" for a physical connection or "AirPort" for wireless broadcasting.

4
Turn on the device you wish to receive the connection. Connect the devices with an Ethernet cable, or turn on the receiving device's AirPort card and connect wirelessly.

Do I need any special equipment other than the ethernet cable connection for my linksys broadband wireless-g router


That's all you need to get your wireless internet up and running. However, in order to connect computers to the wireless network, they must be wireless capable, for example, most laptops have built in wifi, however desktops will need a wireless adapter to take advantage of your wireless router.

Ps3 keeps cutting out wireless internet


You may have an IP conflict. Renew the IP on both the Sonys
At a command prompt,
ipconfig /release
it will come back with all zeros

ipconfig /renew
It should pick up a new IP address.


Intermittent Connectivity:
NOTE: Before following the steps in this article, check if your wireless computers have stable connection when connected to other wireless networks (hotspots).
This article assumes that all wireless computers are experiencing intermittent wireless connection with the router.
Frequent wireless disconnection can be caused by different factors such as:
  1. Wireless interference within the network.
  2. Wireless settings of the router are still set to default.
  3. Firmware is corrupted.
Reducing Wireless Interference
If you are experiencing frequent disconnection from the wireless network, it helps if you check the following factors, all of which can greatly affect your wireless signals:
your cordless telephone system (or even your neighbors’), or other nearby equipment. Try to change your router’s channel to 1 or 11 (the default channel is 6) and restart the wireless computers.
Physical obstructions: Your router or wireless computers may be losing connectivity because of physical obstacles such as walls and floors. Try to move the equipment to different locations to find a better link.

  • Placement of the router: place your router as high off the ground as possible. When placing the router in a high location, leave a distance of two feet between the router antenna tips, ceiling, and wall. If your signal passes through multiple floors, place the router on the upper-most floor, and high up in the room.
  • Surroundings: Keep the router away from large metal objects, bodies of water (fish tanks, bathrooms), and any electrical equipment including television sets, microwaves, radios, etc.
Customizing Wireless Settings of the Router
Having default wireless settings on the router may cause conflict with other routers within your network range. Recommend changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Need wep to connect laptop from school to home network while at home


YOU SHOULD BE ABLE TO FIND THE WEP KEY IN YOUR INTERNET CONNECTIONS. IF THERE IS NO WEP KEY, JUST CREATE ONE AND YOU SHOULD BE GOOD TO GO. THIS CONNECTION LINK HAS A TAB TO SHOW CHARACTERS IF THE KEY HAS BEEN ENTERED. YOU WILL PROBABLY HAVE TO REMEMBER IT, OR JUST CREATE A NEW CONNECTION WITH A NEW WEP KEY! THAT IS THE EASY WAY! GOOD LUCK.

Soundcast act 211 wireless audio system wireless interference w/airport


I'm not familiar with this product but my guess would be that the wireless signal from the audio transmitter is either overriding the wireless in your room.

You might want to consider going to a bluetooth system. It's range is only 30 ft and it doesn't impact wi-fi equipment.

Wireless connection problem


BT is right, the fault is at your end, because you can connect to the Internet with an ethernet cable.
You have lost your wireless connection with the wireless hub.
This could be low signal strength (especially if the wireless access point is in one part of the house and your laptop is in another room)
OR Your laptop wireless card has lost its wireless access configuration.
Check your laptop wireless configuration, check your signal strength, check your SSID, check your security (WEP or WAP),
Have you got MAC address filtering.
Go to control panel, click on network connections, right click on Wireless Network, Click on repair (might fix your connection problem), Else right click on Status (should give you indication of how your wireless is functioning or not functioning).
Check your TCP/IP settings is set for "Obtain an IP address automatically"
Without more information it is difficult to identify exactly what is wrong with your connection.
