Can somebody please explain what a dual router is and how does it work?

It would depend on the context, however what is most likely meant by "Dual Router" is a pair (two) routers for which one is a backup.\n\nParticularly where potentially unstable WAN links are concerned, companies often build a backup router that would take over the wide area connection in the event that the primary (active) router or WAN link fails. \n\nTo support the above Active/Standby configuration, a function known as HSRP (Hot Standby Router Protocol), which is proporietry to Cisco routers may be used. \n\nThe Hot Standby Router Protocol (HSRP) provides network redundancy for IP networks, ensuring that user traffic immediately and transparently recovers from first hop failures in network edge devices or access circuits. \n\nAn alternative to HSRP is a function called VRRP (Virtual Redundant Router Protocol). VRRP is similar to HSRP but non-cisco proprietry (can run on multiple vendors equipment).\n\nTo sum up, deploying dual routers is all about resilience and fault tolerance when building high-availability networks.

your ISP issue IP and subnet fir the WAN and the router issue IP and subnet(unless you are using static IP) for the LAN and thats why you need the router to route the traffic between different subnet (or network).

yes you dont know what you are talking about #1\n\nand if you have PC1 into router 1 via wire\nand PC2 into router 2 via wireless\n\nthey are obviously on two networks. plug PC1 into router 2 and make sure DHCP service is enabled on your router. I am assuming you are talking about those broadband routers that have DHCP service.\n\nupdate:\n\ntake away router 2 and put everything on router 1. You should be on the same network then, in order to get to that PC you  need to browse via IP unless you have a DNS server or if you are using an additional protocol other than IP

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

You're better off just buying a cheap router (like Netgear). If you daisy chain them - from the port to PC A to PC B, for example, then PC A will have to be on whenever you want to use PC B

I'm not sure what you mean by "portable router". All routers are portable - the computer they are hooked to makes no difference to them.\n\nIf you mean "portable networking device" like a USB wireless device, then you'll have to have the correct driver on the other computer for it to use it.

Physically & logically connect the both the routers on same wired lan segment ensure SSID broadcast, passphrase, encryption key on both routers are same..... So that you will be able connect either of the router which can be placed at distance from each other without having to keep 2 different keys on your laptop..... or you can go for a repeater which isn't a router, it simply amplifies the signals that will help you save cost too

Well, first you might be trying to accomplish something that's unnecessary.\n\nConsider: you have two computers, each of which can connect to a network just fine. That means one of two things:\n\n1. Both machines connect to, or CAN connect to, the same wireless router;\n\n2. Each machine is connecting to a separate wireless router, for some reason.\n\nIf the answer is #1, then there's no need to connect the machines directly, because both machines already have IP addresses on the same subnet via the router.\n\nFind out the IP address for each machine (ipconfig in Windows, ifconfig in Linux and OSX) and you'll likely see they're both something like aaa.bbb.ccc.ddd, where aaa.bbb.ccc are the same and ddd are different.\n\nAt that point, you can hit one machine from the other using the IP address of the other machine (try "ping aaa.bbb.ccc.ddd", from machine A using machine B's IP address.)\n\nIf the answer is #2, you're in for a more complex configuration (that can't really be answered here without a lot more information about your system) because you're asking to connect two computers directly on one network, while maintaining connections from each machine to other networks (via the network card). \n\nAt that point, the machine doesn't really know (by itself) which network to use for which kind of connection -- if you hit www.yahoo.com, should it use the wireless or the wired, it has no idea -- and so it likely defaults to the existing wireless connection.\n\nIn addition, connecting machines via crossover cable means there's no DHCP server (which would automatically provide addresses to the machines; routers have this) so the wired cards aren't configured.\n\nIf that's the case, here's what you do:\n\n1. Disable the wireless connection on both machines.\n2. Plug in the crossover cable.\n3. Using whatever method your operating system requires, set machine A like so:\n\nIP ADDRESS: 192.168.0.100\nSUBNET MASK: 255.255.255.0\nGATEWAY: (leave blank, because you don't have one)\n\n...and machine B like so:\n\nIP ADDRESS: 192.168.0.101\nSUBNET MASK: 255.255.255.0\nGATEWAY: (leave blank)\n\nNow you can ping the machines via IP address.\n\nHere's a quick note on "internal" (that is, not internet-accessible) IP addresses, by the way -- there are two ranges that are considered "reserved" for internal use.\n\nRange one: 192.168.x.y\nRange two: 10.72.x.y\n\nWhere x is a number from 0 to 254 and represents the subnet (shared by all machines that should see one another) and y is a number from 0 to 254 and represents the unique address of a single machine (so would not be shared with any other machines on the same subnet.)\n\nI hope that helps.

If you disable NAT then you give up DCHP with allocates LAN IP addresses. You will have to setup a static IP address.\nWhat you may have to do is set one router as "Gateway" and the second router as to "Router". The down side is your second router will have to access the internet thru the Gateway router. On the positive side you could then save the cost of one ADSL, Cable, or T-1 connection.

Basically the router is the one distributing the data & the card on your wife's computer will receive the data being transmitted from the router.  In the sense if your computer is off.. it should work... In what ever mode considering that the router is the one throwing out data to both of your computers.

You will only be able to split your traffic between the two connections with a load balancing router. What I mean is there is no readily available way to connect your 4mb line and 2 mb line to give you 6mb of total bandwidth.\n\nAbout the cheapest you can go is with the D-Link DI-LB604.\nhttp://www.newegg.com/Product/Product.asp?Item=N82E16833127069\n\nThis router will allow you to make both Internet connections available to your network, but it lacks any built in wireless connectivity.

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

Do some testing.  Try http://www.dslreports.com with and without your P2P service activated.  Repeat the test with your computer connected directly to the high speed service.(without the router)\n\nProve that this is the router!\n\nGood luck and Happy Computing

A server is a device (either a stand alone computer, or an application within one computer) that manages network resources.  This can be as simple as a print server, that allocates printing resources from different computers to a server that houses pages of websites.\n\nA router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs (local area networks) or WANs (wide area networks) or a LAN and its ISP’s network. Routers are located at gateways, the places where two or more networks connect.\n\nA switch is a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs.\n\nGenerally, in a home setting, you do not have either a stand alone router or a swich.  You have a modem (DSL or Cable) connected directly to the ethernet connection of your computer, or a built in dial up modem in the computer that utilizes a telephone line to transfer information.  If you have a wireless network at home, however, you most likely have a switch built into your wireless router.  Most home routers generally have four different ethernet connections that you can hook different computers to.  It is a switch that allows the router to have 4 connections.  In a larger setting, a switch is a seperate device.  The most commonly used switches are made by Cisco, and the typical switch has 24 connections.  Linksys is the division of Cisco that provides hardware to home users.  Even if you don't have the need for wireless networking or to connect several computers together, it is advisable to have a router between your modem and your computer, as the better home routers have built in firewalls that will in essence make your computer invisible to hackers searching for computers.

If the laptop is configured to have a wirless network card then you should be able to piggy back off of someone else router otherwise your going to need a network card iniside.

Short answer:\n\nA router is an intelligent device that allows a central connection to an internet connection.  Basically connects a LAN to the internet.  It also provides many internet like services from that single connection to the PC's connected to it.\n\nA hub is a dumb networking device that only passes all traffic from one computer to all computers connected.  It does not route the traffic in any way.  It's for local area networks only.\n\nThere is also a switch which does a small amount of traffic control in a local area network.  This helps make connections in the LAN faster with 3 or more computers.
