Type the following in the command prompt window.\nping 127.0.0.1\n(This runs a loop back test through your NIC.)\n\nThe result must look as follows:-\nPinging 127.0.0.1 with 32 bytes of data:\n\nReply from 127.0.0.1: bytes=32 time<1ms TTL=128\nReply from 127.0.0.1: bytes=32 time<1ms TTL=128\nReply from 127.0.0.1: bytes=32 time<1ms TTL=128\nReply from 127.0.0.1: bytes=32 time<1ms TTL=128\n\nPing statistics for 127.0.0.1:\n    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),\nApproximate round trip times in milli-seconds:\n    Minimum = 0ms, Maximum = 0ms, Average = 0ms\n--------------------------------------------------\nipconfig /all\n\n(This displays configuration details of your NIC)

Based from my learning experience, you should do this:\n\n\nGo to Network Neighborhood\n    >Properties\n         >Client for Microsoft Network\n         >TCP/IP\n                >Properties> I.P. address> subnet mask will  \n                 automatically displayed\n                 make sure the I.P. address is different to one another    \n                   ex. 198.176.0.1  for PC1\n                          198.176.0.2 for PC 2\n                          198.176.0.3 for PC 3\n        > Ethernet/LAN Card\n           --->Click Add Tab-> Protocol > Microsoft ---> NETBEUI\n                                                                           ---->IPX/SPX\n        > File and Print Sharing (check the box)\n\nGo to My Computer\n      > Open> Local Disk > properties > Network Sharing and      \n                                                                 Security  \n      > Properties > Computer Name: PC1, PC2 or PC3 \n                               Workgroup: (any word must be the same )

Check the modem to see if there are still any DHCP address left for it to hand out. Check if the DHCP server can hand out IP addresses to the wired computers, not just to the wireless computers.\nCheck if you can have both a wireless and a wired connection at the same time (some modems will only allow one type of connection). Check if your network card is installed properly. Check if the cable is still good, swap it with a different cable if you can.

You may check\n- BIOS for enable PCI Ethernet cards\n- Driver if it is up-to-date\n- Driver is for this OS\n- Using another PCI slot in case, may be the PCI slot is not working.\n- Mark be as best answer may help you also\n\nXLMan

get in to your router. type your router address at ur web browser (eg.192.168.1.1). usually your router can show you how many computer are connected to it. Or use a sofware like Network magic. u can found it at www.downloads.com

Log into the Router, then look at the LOG file.  This will probably be a dead give-away.

if it only has one output then you need to by a splitter or router, if it has a router built in then you can simply connect them both to it then go into ( assuming ur on windows ) my network places, then set up a new home network

1. verify the number of computers eu have\n2. verify status of the lights on the modem\n3. if eu has 2 computers and the modem is in sync, make sure that the first computer is connected before transferring to 2 wire dept.\n4. if eu has one computer and the broadband link light is orange, ask eu to go to the gui for 2 wire(http://172.16.0.1 or http://homeportal/set-up) and run the system set-up wizard\n5. if power=green broadband link=green lan=off run bbt and transfer to two wire

go to tools, internet options, connections, and make sure it is checked never dial a connection, click on lan settings and make sure automatically detect is checked

I am not a Mac person, but I don't think that matters in this case. I assume you've got your DSL modem connected to the wall jack, and your 2 port router connected to the DSL modem. Can you connect to the internet if you connect your pc or Mac directly to the DSL modem? If this works and connecting through the router *doesn't* work, there are a few things to check. It could be an issue of the ISP knowing the MAC address of your pc and of your Mac, but it doesn't recognize the MAC address of the router. In the router configuration, probably under advanced settings, there should be an option for "cloning" a Mac address. If one or the other of your machines can connect to the internet when connected directly to the modem, it is the MAC address of *that* machine that you'll want to clone. To get the MAC address on a Windows box, click Start -> Run and type "cmd" to get to a command prompt. Then type "ipconfig /all" (without the quotes, of course). Copy down the "Physical Address" of your network card. Then enter this as the "cloned" MAC address on your router. It may be necessary to do a soft reset of the router at that point. Once it comes back up, the ISP's network will think that your router is in fact your PC, and everything should work just fine. At that point, you should be able to connect both computers to the router and all should be well. If not, while you have both computers connected to the router, see what IP address each has. If neither has an IP address (they should have private IP addresses, something like 192.168.1.x or 192.168.0.x), then in your router settings, you'll want to enable DHCP. If however, your router does not offer DHCP, then you'll need to do something like get an old PC (seriously...something like a 400Mhz will do just fine), install a 2nd ethernet card, and then install Smoothwall or IPCop on it. These will handle the DHCP stuff for you (in addition to providing you with an excellent perimeter firewall). In this case, your setup will go from wall to DSL modem to Smoothwall/IPCop box to router.

Make sure you follow the first-time setup instruction in the package.  \n\nUsually, for first time installation, you have to make sure that the router is connected ONLY to the computer first, before connecting it to the rest of the network or ADSL modem when prompted by the Setup Wizard.

You are going to have to be much more specific in your question.  Are you referring to a LAN operating system, just connecting a few PC's together, or a multi-user application software (and in this case, what application?)

First order of business is to install a 2nd network card (assuming that your old computer only has one). The next step is to install something like Smoothwall, Monowall, or IPCop. I've used Smoothwall extensively. It is easy to install and very easy to configure. There is copious documentation and step-by-step guides for the whole installation and setup process. In my experience, you can't go wrong with any of these three options.

Yes each computer wireless card or ethernet card has a mac address.  they can trace from where ever to the router then check the router for the logs of the ip address it has gave out then look for the mac address of the last time the ip address was used.  Then just wait till you get on it again you can only be so far from the wireless router. :) Don't do anything shady :)

If you changed the default admin password on the router and enabled encryption, thats a good start.\n\nYou could also set the router to only accept signals from your system by specifiying the MAC address of your NIC

Hi, Here are a few things to try..\nCheck your connections (cable, NIC, router) Does your NIC have a connectivity light on it? most have a light that shows connectivity and traffic. If there is no light on check your cable. Does your router have connection lights? Check that as well. Try hooking your NIC into a different port on the router. Look in the DHCP settings of your router and see what the range of addresses are being assigned. It may be set to only assign a few.\nIf you are using a static address, you must make sure you are using the same Sub-net mask, address pool &  gateway as your other systems on your Lan. If you know all this is good, then  make sure you have updated drivers for your NIC, you can also try uninistalling TCPIP and re-installing it.
