there are several ways....over email, or >>>ftp>>>but you got to be on the Ethernet with both computers...

LAN = Local Area Network - Usually used in a single office\nWAN = Wide Area Netowrk - Multiple locations share the same netork with the use of T1's hubs and routers.\n\nThey are pretty much the same.

Hey go to this link and you will find some good information about networking http://computer.howstuffworks.com/question353.htm

2 or more computers in a networks can be connected together using cables or via wireless (Wi-fi)technology.\nLike all other technologies, wifi has +s and -s.\nto get more technical and detailed information you can go to http://www.cnet.com to read more.

First, get an ethernet hub or switch. (If you're going to connect more than two computers then a switch is a better choice)\nMake sure you have an eternet port on each. (If they are different speeds, they'll need to either be 10/100 capable, or you'll need a 10/100 hub or switch. (Of course if you have gigabit, you'll need to account for that as well)\n\nOnce you connect the computers, setup networking on Windows. You'll need to do a little configuration, but the wizard makes it easy. You might have to make one a DHCP server, unless you have a router on the network. If you've got Cable or DSL, the router that you are using for that has DHCP which will setup the IP address of each computer.

What you'll need will depend upon the distances involved.  Two wireless access points with directional outside antennas (the so-called Pringles can type) can reach up to a mile or more.  Beyond that you'll probably need a parabolic dish.  That setup can reach up to 22 miles (!!) with very careful aiming.  Either of these are limited to line-of-site.\n\nIf you want the best possible connection, go with Cisco Aironet gear.  It's expensive -- $4,000 or so for two Aironets, two parabolic dishes and 50 feet of wave guide at each end -- but well worth the expense.\n\nAnother possibility is the Proxim Tsunami wireless bridge.  A pair will set you back about $3500.00.  Range is limited to about 6 miles but they are dead easy to set up, far easier than the Cisco Aironets.  If you ground the mast properly (read the docs!) they can even take a direct lightning hit.  That's not guaranteed, but I've worked with them and seen it happen.

Don't know if this will do any good, BUT, I experienced the same difficulty (and same messages)and I finally tracked it down to a hardware problem (at least in my case!) I was using an old (used and cheap) hub with a connectivity max of 10 meg. When I upgraded to a 100 meg hub the problem went away. And my LAN is now quick as a deer!

The hard part about this would be getting distance networking going.  You would either have to have some majorly expensive equipment, that communicates via satellite to receive internet service, or else the infrastructure would have to be put into place in the areas you're working in.  It depends on what kind of distance you're talking about, really, but honestly, you're looking at some MAJOR costs, and potentially even a lot of bureaucratic red tape depending on the method of transmission between the sites.

Yup???\nIn Internet, itz not possible.\nIn LAN's itz possible.\n\nThat is Two different LAN's can use same IP with Different host names.

Ok let's start with a review of the answers so far.\n\nImperial: "they're both used to provide internet connectivity."\n\nSorry that's not right. I can use a hub in a network with no Internet connectivity.\n\nMarker: "A router uses software to send the information directly to the intended port."\n\nI understand what your trying to say but it didn't come across right. A router uses internal software (firmware typically) to direct traffic to the correct network.\n\nexquisite Computers& PU's Q&A: "Router are used in wan as the hub is use in lan Thats the main difer in these"\n\nNOT! Dude please get some networking knowledge before making such wrong, blanket statements. I can have a router in my lan but it cannot perform the same task and a hub in my wan certainly doesn't.\n\nThe other answers are pretty good so I won't repeat what they said.\n\nTo answer your question you need a device that will at least do NAT and a hub cannot do this. Typically your probably looking for a home type DSL/Cable router. For businesses I would suggest something higher end and a asking for support from a local technology provider

You can make a "bridge" with the second one.\nAnd then both will be in the same network and internet connection.\n\nYou can also force the second wireless to operate in a different channel than the first one (protocol 802.11b has 13 channels), so you will have 2 wireless networks completely independent from each other.

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

Quite possible. No need for USB Modems too. Simple PCI card type modems ought to do it. Dial each one after the other. Select both. Bridge 'em. Then connect the bridge to your high speed lan.

A network hub with both types of connection will do it. Probably cant get an actual hub, since most such devices are switches these days

You can use wireless bridges, which with the right antennas have a range of up to 25 miles if you have an unobstructed line of sight.  Somewhere in the middle, you'll want to find someone who owns a tall object (radio stations, cell phone companies, billboard companies) which you can see right to from both offices, and is willing to let you mount a bridge up there.  \n\nSo, you'd have one wireless bridge on the roof at the first office, with a powerful antenna pointed straight at a wireless bridge on a tower several miles away.  It'll have one antenna pointed at your first office, and one pointed at your second office.  At your second office, you'll also have a powerful antenna, and it'll also need to be pointed straight at the bridge in the middle.  \n\nYou'll be able to get a much faster connection than you could with VPN over ordinary internet connections.  Most office internet connections have bandwidth of 1-3Mbps total, which would have to carry your VPN traffic and your regular internet traffic (email, websites, ect).  With wireless, you could easily have a huge 11Mbps pipe.  By the way, for the distances you're dealing with, I'd expect about $8000 worth of equipment.  Some companies flat out buy it, some spread it out over two year payments.    \n\nCity people won't always bother doing wireless, but I've talked to people with offices in the middle of nowhere, who loved their  bridges.  Some organizations also find it quite a bit more cost effective than buying internet access at each location.  \n\nMost companies will do VPN instead of buying wireless bridges. You'll need an internet connection at both offices.  If you have an office firewall, it probably has VPN functions.  For a very simple, reliable setup, get a good firewall/vpn box at each location, and just connect them, as a site to site VPN.  \n\nA 1300 series wireless bridge:\nhttp://www.cisco.com/en/US/products/ps5861/index.html\n\nA couple of good firewalls (Cisco's classic Pix, and their new ASA):\nhttp://www.cisco.com/en/US/products/hw/vpndevc/ps2030/index.html\nhttp://www.cisco.com/en/US/products/ps6120/index.html
