It ain't pretty, but you need a second NIC in the computer that will connect to the modem. Use the connection wizard to connect direct to the internet (modem) on the first computer. Set the second computer to access the internet thru another computer or router. Use a crossover cable to connect the first and second computer via NIC #2.

You need to reinstall the the modem software so that the os can detect the modem. If that doesnt work then you can try unplugging your modem and plugging it again after restarting the system. Get back to me if that doesnt solve your problem

Please check if you have dynamic ip address in your TCP/IP settings. And LAN settings should be set to automaticlly detect settings. :) Sometimes you need static ip to work, by changing the ip add to 192.168.0.1 and subnet mask to 255.255.255.0, and the leave the gateway blank.

Simply go to Start>Network Places or simply go to Windows Explorer (Windows button + E on the keyboard) to view Network places.   It will provide you with info on whcih computers are connected to yours.  This usually works if your computer is connected to other computers on a LAN or Ethernet.

if it says "Local Area Connection unplugged" then that isn't a result of bad weather or a problem with your ISP.  The reason this could be is on the switch/hub (whatever you use to connect your computers to the internet) or even the RJ-45 port on your computer might be damaged or not all the way plugged in.  This would cause you to temporarily loose connectivity between your computer and the switch/hub, and the computer would read this as a cable has been unplugged.  There really is no fix to this other than just make sure your cables are plugged in securely to both your switch/hub and your computer.  If this problem persists, look into possibly getting a new network card (can find them at walmart for like $15) or even replace your switch/hub.

You need DSL or cable or some sort of ISP. To connect to LAN you will need to connect your computer to your ISP, usually via ethernet. Normally once you plug the ethernet into your computer, then you can use LAN to connect.\n\nGo to this website: http://www.cablemodemhelp.com/lanconnect.htm\n\nand it will explain it better with pictures =)

Firstly ensure that that can both communicate with one another. To do this try pinging one another, i am assuming you both have winxp. Ping your computer. see if their is packet loss. If their replace the cables. TO do this click start - run - cmd then type ping then from your laptop his name or pref his IP, check his ip by right clicking tcip/ip properties in my network places - then view network connections. If you can you can communicate to his pc and you used a straight cable (the wires are the same at each end) a hub is generally old so your probably using a switch which might forgive the use of crossover cables. Make sure you are both part of the saem work group (right click on my computer - computer name) and put static ip' in both your computers (192.168.0.1-254) where 1-254 is a range. Are ou both running the same operating systems? very important Turn firewalls off NB!

Does your router have an active internet connection. If you unpluged the cat 5 cable from your laptop and then connected it to the cable or dsl router you will need to reset the modem to reset the MAC address or you will not get on line.  After that I would check your security setting on both router and laptop and make sure they both match.

About Wired LANs\n\nWired LANs use Ethernet cables and network adapters. Although two computers can be directly wired to each other using an Ethernet crossover cable, wired LANs generally also require central devices like hubs, switches, or routers to accommodate more computers. \nFor dial-up connections to the Internet, the computer hosting the modem must run Internet Connection Sharing or similar software to share the connection with all other computers on the LAN. Broadband routers allow easier sharing of cable modem or DSL Internet connections, plus they often include built-in firewall support. \n\nInstallation\nEthernet cables must be run from each computer to another computer or to the central device. It can be time-consuming and difficult to run cables under the floor or through walls, especially when computers sit in different rooms. Some newer homes are pre-wired with CAT5 cable, greatly simplifying the cabling process and minimizing unsightly cable runs. \nThe correct cabling configuration for a wired LAN varies depending on the mix of devices, the type of Internet connection, and whether internal or external modems are used. However, none of these options pose any more difficulty than, for example, wiring a home theater system. \n\nAfter hardware installation, the remaining steps in configuring either wired or wireless LANs do not differ much. Both rely on standard Internet Protocol and network operating system configuration options. Laptops and other portable devices often enjoy greater mobility in wireless home network installations (at least for as long as their batteries allow). \n\nCost\nEthernet cables, hubs and switches are very inexpensive. Some connection sharing software packages, like ICS, are free; some cost a nominal fee. Broadband routers cost more, but these are optional components of a wired LAN, and their higher cost is offset by the benefit of easier installation and built-in security features. \nReliability\nEthernet cables, hubs and switches are extremely reliable, mainly because manufacturers have been continually improving Ethernet technology over several decades. Loose cables likely remain the single most common and annoying source of failure in a wired network. When installing a wired LAN or moving any of the components later, be sure to carefully check the cable connections. \nBroadband routers have also suffered from some reliability problems in the past. Unlike other Ethernet gear, these products are relatively new, multi-function devices. Broadband routers have matured over the past several years and their reliability has improved greatly. \n\nPerformance\nWired LANs offer superior performance. Traditional Ethernet connections offer only 10 Mbps bandwidth, but 100 Mbps Fast Ethernet technology costs little more and is readily available. Although 100 Mbps represents a theoretical maximum performance never really achieved in practice, Fast Ethernet should be sufficient for home file sharing, gaming, and high-speed Internet access for many years into the future. \nWired LANs utilizing hubs can suffer performance slowdown if computers heavily utilize the network simultaneously. Use Ethernet switches instead of hubs to avoid this problem; a switch costs little more than a hub. \n\nSecurity\nFor any wired LAN connected to the Internet, firewalls are the primary security consideration. Wired Ethernet hubs and switches do not support firewalls. However, firewall software products like ZoneAlarm can be installed on the computers themselves. Broadband routers offer equivalent firewall capability built into the device, configurable through its own software.\n\nAbout Wireless LANs\nPopular WLAN technologies all follow one of the three main Wi-Fi communication standards. The benefits of wireless networking depend on the standard employed: \n802.11b was the first standard to be widely used in WLANs. \nThe 802.11a standard is faster but more expensive than 802.11b; 802.11a is more commonly found in busi

Seems like that simple LAN setting was not that simple. You should check that there are not conflicts (like same IP, different subnet or gateway) are using DHCP or static configurations? also are you using a router or switch? What do you mean by server? \n\nAt any rate you should not have to restart your PC to reconnect.\nDid you try to disable and enable again the LAN connection. Also you can go on the command prompt and type : ipconfig/release  [hit enter]\nipconfig/renew    [hit enter]

If you mean you want to network your two computers together using a USB cable, you can just use the networking wizard at Start --> Control Panel --> Network Connections. \n\nIf they're hooked together, they should see each other via your A-to-A cable.

There could be several ways of doing that.\n\n- Unplug the networking cable from the LAN card.\n- Disable the networking in your OS\n- Disassembling the LAN card from your PC (if you are connected through wireless) etc. etc.

just buy a router and a modem.\n\nconnect the modem to your power source, and then connect the router to the modem. the router transmits wireless signals. therefore, no matter how many computer systems are in a certain region, all of them get to experience LAN connection.\n\nBEST ANSWER? (:

get two comps , plug em together , hey presto you have a LAN

You should specify which model router you have, and what type of computer and operation system software - laptop or desktop, Windows version or Mac OS.\n\nAlso mention what setup you were using to connect when it used to work on wireless.\n\nA telephone modem and Ethernet LAN connection would not generally be a wireless capable device in your computer.  It could be that the icon controlling your WIFI hardware is clicked to the OFF position.  Check each item in the lower right screen system tray using right-click of the mouse.

As soon as you give your computer a name it will show up in network neigborhood. Most likely you have done this while setup the OS.\nRight click on My computer / Tab Network Identification / Properties

If you believe that you have a "wireless connection"  most likely you do have a "wireless pc adapter" already built-in.\n\nTo verify, go to the command prompt:\nstart->run\ntype cmd and hit enter\nat the c:&#92; prompt type the following:\nipconfifg /all\nif you see anything there that says wireless\nyou are in business.
