We, Future Group Bangladesh needs a very long area networking. The IT Department's has already a network (both private and public) Now some other compueters have to be connected in the private network. We have a switch in our IT Department and from this switch we have to make a connection with another switch that is in our DMDs romm which is about 80ft far away from our switch. We tested both straight and cross cabling from switch to switch but it didn't work.
This is a very specific problem that requires a site visit to solve, there are many factors that can effect the transmission of data over a run of that length. There are many solutions to this problem, they range from rerouting the cable run to avoid sources of interference to selecting another medium such as WLAN or IrLAN. The specific implementation of the solution must be custom tailored to the situation, sometimes the solution requires equipment that is readily available on a store shevle and sometimes the solution must be engineered to accommodate the needs.
I would recommend looking at the cable route to see if it runs past any major interference makers (copiers/large office machines, industrial equipment, power equipment). Then look at the possibility of an intermediate repeater/router (protected location and availability of power outlets). Another possibility is a wireless technology, the specific technology depends on many factors. If you need high speeds or large data transfer, perhaps an Ir (Infra-red) link or WiMAX (802.16) would be best. If general purpose network connectivity is needed, then a standard 802.11 a/g WLAN will suffice. I recommend that you contact a local networking firm for a detailed consultation. Another resource that might be a better fit for most small budgets will be to contact the local college/university that has a well defined IT program to solicit members of the Alumni in a networking degree field.

you will have to open up your network connections click start control panel network connections this may vary depending on your operating system look for local area connection if you see a red X or a yellow exclamation or question mark ! ? you will need to update or install the driver or it could be firewalled click start control panel administration tools computer management device manager scroll to network adapters should see a yellow question mark? right click install drivers the driver might be on the disc supplied by your ISP internet service provider or the motherboard disc or you might download one if you dont have on a disk

sure you have run the Network Setup Wizard on each of your computers,
even if you have configured it manually. Your file and printer sharing
are disabled until you run the wizard at least once.
jQuery('#jsArticleStep2 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.2-800X800.jpg');
the problem is that some of your computers appear in My Network Places
or View Work group Computers, while others do not, wait about 20 minutes
or so and then check again. If all computers still do not appear, and
you have older versions of Windows running, like Windows 9x or Me on
your network, restart the Windows XP computers, wait for about 3 to 4
minutes then start up your older computers. Wait for a few minutes then
check again. If that does not work try booting your computers in
jQuery('#jsArticleStep3 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.3-800X800.jpg');
On each of your computers, click Start, My Computer,
select My Network Places, and then select View Network Connections Look
for the Local Area Network Icon. See if the Icon says "disconnected".
If the answer is yes then you have a problem with your cables or your
network adapter. Repair before proceeding.
jQuery('#jsArticleStep4 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.4-800X800.jpg');
look to see if any of your Local Area Connection Icons say "Firewalled"
next to them. If you find this problem then Your Windows Connection
Firewall might be blocking printer and file sharing on that computer.
Go to your Firewall Protection and make the needed changes.
jQuery('#jsArticleStep5 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.5-800X800.jpg');
thing to try is to go to start and right click on My Computer and
choose Properties. View the computer Name tab. Each of your computers
should have a different name and the same work group name on it. If they
do not have different names then you will have to change them. Restart
your computers you adjusted and see if this made a difference.
jQuery('#jsArticleStep6 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.6-800X800.jpg');
can also try something else by going to each computer and click Start,
All Programs, Accessories and then Command Prompt. In the Command
Prompt window, type ipconfig and then press Enter. Under the Local Area
Command Prompt entry, Windows should show you a different address for
each of your computers. If any of your computers have the same address
or if the addresses are not similar, then you will need to repair this
jQuery('#jsArticleStep7 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.7-800X800.jpg');
the same Prompt Window as above and from only one computer, use the
ping command to see if that computer can communicate with each of your
other computers. To do this, type x.x.x.x in the Command Prompt Window.
You are substituting the actual I.P address of your other computers for
x.x.x.x in turn. You should be seeing several Reply from lines each
time you do this. If any computer does not respond, then you have a
cable or hardware problem. Repair this first then proceed with further
jQuery('#jsArticleStep8 span.image a:first').attr('href','http://i.ehow.com/images/a05/k7/ln/troubleshoot-_a-home-network-1.8-800X800.jpg');
Make sure that all of your computers have the same network protocols.

you still are having trouble with your Windows Network you may have to
call in a professional or a computer experienced friend to help you.
A hub is basicly a connection splitter that transmits ALL data recieved to ALL computers connected to it. Only the computer identified as the "correct reciever" recieves the information that is brodcast, all other computers discard the information as garbage.a Hub will increase network traffic with more computers connected to it
A switch does the same job splitting a signal to multiple computers, but rather than sending ALL information to ALL computers, it will send the information Only to the correct computer. A switch will use less network traffic, sending only the information to the correct computer rather than "broadcasting" information to every computer on the network.
You can configure a server that allows remote users to access resources on your private network over dial-up or virtual private network (VPN) connections. This type of server is called a remote access/VPN server. Remote access/VPN servers can also provide network address translation (NAT). With NAT, the computers on your private network can share a single connection to the Internet. You can find a step by step guide here:http://technet.microsoft.com/en-us/library/cc736357(WS.10).aspx
We can assign ip address to the windows based computer using these steps . Click Start, click Control Panel, click '''Network and Internet Connections, and then click Network Connections.''' Right-click the network connection that is connected to the private ICS network, and then click Properties. On the General tab, click Internet Protocol (TCP/IP) in the '''This connection uses the following items list, and then click Properties.''' On the General tab, click '''Use the following IP address. Configure the entries as follows: #* IP Address: The IP address you chose for this client (for example, 192.168.0.100). #* Subnet Mask: 255.255.255.0 #* Default Gateway: 192.168.0.1 #* Click '''Use the following DNS server addresses, and then type 192.168.0.1 in the '''Preferred DNS server box.'''''' ''' Click Advanced, and then click the DNS tab. In the '''DNS suffix for this connection box, type MSHOME.NET.''' Click OK. Click OK. Note: There are
for 10/100 connections you can do this (look on eBay for "Lan Splitter cable"). This is because for lower rate Ethernet there are spare pairs of wires in the cable. If you intend to run 1GBps then it needs all of the pairs in the cable and you will not be able to use the splitter.
The better solution would be to either use a switch in the room to break out the one cable you already have, or to run a parallel cable. As you may need extra LAN connections in the room in the future, the switch is generally the best method.

Hi raji767. You left out a few important details such as which operating system you are using and if the WiFi signal you are trying to connect to is encrypted. I will try to give the best step by step instructions I can based on the info you gave. I am assuming you are using either Windows XP or Vista. First, make sure the wireless is turned on. There is a button on the side by the headphone jack which turns the wireless on and off. WINDOWS XP: Click Start, Control Panel. On the left side of the control panel window you should see "switch to classic view" or "switch to category view". To make it easy, make sure you are in classic view. Next double click the icon labeled "Network Connections". Next, right click on the "Wireless Network Connection" and select "View Available Wireless Networks". In this window you should see the network you are trying to connect to. Next just select the network and click connect. NOTE: If the network is encrypted, you will need to enter the key after pressing connect. VISTA: First, go to "Start Menu", "Control Panel", "Network and Internet". Next, go to "Network and Sharing Center" and select "Connect to a network". Choose "Show All" and hit the refresh button. Now just select the network you want to connect to and click connect. NOTE: If the network is encrypted, you will need to enter the key after pressing connect. Hope this helps. If you have any questions just let me know. Good Luck!
