Adding a Second router to my LAN

I have 4 devices in my network - 
1. Cable surfboard modem
2. WRT160N Wireless Router - 192.168.1.1
3. Linksys 10/100 5-port wired switch
4. WRT160Nv3 - 192.168.1.2
My current setup is -
1. Modem to first router. (WAN PORT)
2. LAN Port from router to UPLINK port on switch
The switch is upstairs, the router is downstairs.  The wifi from the router does not reach upstairs, so I have bought another WRT160Nv3
How do i add this to my setup?  I've tried hooking the new router direct to a PC and configuring it so that it is NOT a DHCP server and changed the IP from 192.168.1.1 to 192.168.1.2 then connecting a LAN port from the switch to a LAN port on the new router and disconnecting the wired pc from the new router.  
In the above setup NOTHING after the switch works.  I cannot get internet while the switch is connected to the second router on any computer attatched to the switch.  The wifi will not get internet either (from second router)
Any assistance would be greatly appreciated.  I am not trying to make a repeater using the same SSID, just simply trying to add an access point onto my current setup.

Make sure you have plugged in the switch and that the power switch is in the on position (sorry for the basic instructions, but i've had experiences with people overlooking common sense steps).
One other question...does the switch work correctly with just the primary router and a computer or just the secondary router (with DHCP turned on) and a computer?
I don't work for Cisco. I'm just here to help.

  • Adding a second router with WIFI

    Whats the best way to add a second router with WIFI for my shop do I need a switch or can I just plug into the back of my exsiting router.

    Here is article in the Cisco Knowledge base for turning a router such as the e4200 into a access point.
    To do this you would connect a ethernet cable between the two routers.

  • I can't add second router AirPort

    Hi,
    I've a problem with adding a second router in a another floor. I've AirPort Extreme A1143 (802.11n 1.generation) connect to the internet in second floor of my house. It's working correctly.
    I want to add AirPort Express A1392 in the first floor by ethernet cable. It's connected to the LAN In Extreme (base station), and into the WAN in Express. Express is factory configuration; light flash amber. I can't see express in Utility AirPort (Mac is at second floor, connected (wifi) to extreme.
    I'd like to create one wifi network in my house with the same wifi name, password. Is it possible?
    OS X 10.9.4

    I'd like to create one wifi network in my house with the same wifi name, password. Is it possible?
    Yes it is.
    Have you tested the Ethernet cable connection between the AirPort Extreme and the location of the AirPort Express?
    If not, please temporarily connect the Ethernet cable to a laptop or other device and turn off the wireless function of the laptop. See if you can get a good Internet connection on the laptop when you test this way.
    If you can, the Ethernet cable is working correctly.
    If you cannot, then there is a problem with the Ethernet cable or something else and it will need to be fixed before you can proceed with the installation of the AirPort Express.
    Please clarify on your results.
    Also, please clarify if you have an iPhone or iPad for use in the installation of the Express.

  • Adding a Netgeat router to a network.

    Hi guys. I never thought that I'd need to ask this at this point in my life. For years I've been setting up, every now an then only though, small domestic networks and, altough some had taken me time, I've eventually made them work.
    Anyway, the current configuration is: One wired/wireless router from which 5 computers take the internet. One of them is mine and the cable length is fairly long, probably about 50 meters. My computer connects, I believe, perfectly to the router. All my computer network settings were automatic. I had to input nothing.
    When I connected my Airport Express in order to create a wireless subnetwork, it also automatically set all the addresses and seemed to work straight away. I'm afraid I believe the length of the cable causes the network (now wireless between the AX and my MBP) to become extremely sluggish if it works at all. The webpages kind-of are going to load, but never to completion. I thought this was because the AX after all, imho, is not meant for these tasks but for rather domestic layouts.
    I tried then replacing the AX with a proper (so I believed) router: a Netgeat WGR614. I believe it doesn't have automatic network detection so tried setting all the IP addresses manually, basically copy-pasting the settings that the AX adopted automatically, but never got to put it to work. Furthermore, I couldn't access the settings page on the browser because I changed its own address (if anyone know how to access the routers' settings once you've changed their IP address I'd appreciate if you'd explained to me).
    So I master-reset the router with that button at the back. Now, as soon as I access the settings they force me to follow some sort of network wizard that leads me nowhere and inevitably (since I always change its IP address) I get left out of the settings.
    What do I have to do here? In the past I've added routers to create sub-networks but I cannot do it now, why?
    Could the router be faulty? Or could it suffer as well from the same long-distance cable? The router that access directly the internet doesn't seem sturdy at all, but rather cheap, so I blame it mostly. It's a SpeedTouch XXX disguised as a BT Home Hub.
    With the Netgear router how do I bypass the wizard and jump straight into the settings page?
    Thanks guys.

    (I have a a WGR614v6 - works great for me in a single-router setting)
    The WGR614 is a bottom of the line cheap router - I too had trouble following the built-in wizard when I tried to set it up as a wireless access point add-on at school. To access the admin web page, I just enter http://[LAN-sideaddress_ofrouter]
    Adding a second router is a tricky business - you don't want it to be a router, you want it to be a wireless access point only, so that your first router is doing all the usual things: NAT, firewall, DHCP. If you leave it doing router things, your second network will be isolated from the computers in the first router's network.
    Does that help?

  • ActionTec + second router = port forwarding issue

    I'm having an issue with port forwarding (or maybe routing) across a pair of routers with different subnets. I know just enough about networking to be dangerous, but I can't figure this out. Hopefully someone more knowledgeable here can assist me.
    Here's how my network is currently setup:
    1) Standard FIOS ActionTec MI424-WR Rev D router, using default 192.168.1.* subnet.
    2) Added a second router (D-Link Wireless-N w/ Gigabit Ethernet) using the 192.168.2.* subnet.
    3) A patch cable connects an ActionTec LAN port to the D-Link WAN port. 
    4) Most of my computers connect to the D-Link router for faster network speeds (desktop PC, NAS, etc.)
    5) Both routers are running DHCP and broadcasting different SSIDs. This is so I can have a private network for my personal data (192.168.2.*) and a guest network (192.168.1.*) that friends/family/guests can use. Basically, from the 192.168.2.* network, I can access any network resource on either subnet; the 192.168.1.* network, however, cannot (easily) access the resources on the other subnet. 
    6) This setup works perfectly and has met all of my needs so far.
    Now, the problem I'm running into:
    I purchased a security camera to monitor my home over the internet while away. It is connected to the D-Link router and I can access the camera without issue while on the 192.168.2.* network. Everything works fine locally. However, I cannot access the camera from the internet.  For sake of ease, let's use the following example setup:
    Internet IP = 74.1.2.3
    Router 1 = 192.168.1.1
    Router 2 = 192.168.2.1
    Camera = 192.168.2.2
    Camera Port = 12345
    Accessing the camera locally via http://192.168.2.2:12345 works fine, but accessing it remotely via http://74.1.2.3:12345 does not. I assume a route or port forward needs to be set on Router 1 (the FIOS ActionTec)? Any help is greatly appreciated.
    Thanks,
    -Patrick
    Solved!

    For future viewers, I will throw this out there. You don't normally want two routers with two port forward rules. The best practice is to give the second router a static ip on the lan of the first router and then put the second router in the dmz of the first router, and then apply port forward uses to the dmz'd router.

  • How can i use a second router to replace verizon fios router?

    Okay so just as the title says how do i use a second router? I got a cisco valet router... I don't know how to use it because the verizon router/modem is wierd i know how to use a router if i only had a modem but fios gives router/modem so how can i use my 2nd router? The current verizon fios router/modem is b/g mode and i wanna change to b/g/n so i can get a better speed from my internet... SO how can i use my 2nd router? I tried this http://www.dslreports.com/faq/verizonfios/3.0_Networking#12506 but i don't get it can someone guide me better or make a video explaination on how to use a 2nd router? I have it connected with see as in pic i connect from my router Internet port to wan port and the ethernet lan port to the ethernet lan port on verizon fios and no work please help...

    OK, so with this, we have a few options. You appear to have a MoCa connection to the ONT, hence the coaxial cable being present.
    1: The ActionTec can be bridged to the Valet router. This will not require any additional cabling, however it will require a small amount of work to have working. You will also require the ActionTec still in the mix, even though it will not be acting as a router anymore with this configuration.
    Visit http://www.dslreports.com/faq/16077 and look at Option 4. There is a thread linked that will allow you to set up the ActionTec as just a MoCa bridge, and will pass the Public IP to your router. You will, in order for this to work once the ActionTec is bridged, need to connect the cable from your Valet router's Internet port, to the ActionTec's LAN port and nothing else goes to the ActionTec. From this point, your Valet should run as your primary and everything should connect through your Valet. If you are adding another router, a Netgear N300, you should perform the LAN to LAN setup, which we will talk about once you've got the Valet working correctly. LAN to LAN configs require a custom setup, so do not set up the Netgear for now.
    2: This is my preferred method, which would be to run an Ethernet cable to the ONT. Option 6 in the FAQ. This will require spaking to Verizon to have them move your ONT to Ethernet, but once they do this, you can disconnect the Coaxial Cable from your ActionTec router, and plug in your CAT5/CAT6 cable from the ONT to the ActionTec's Internet/WAN port. Use the ActionTec to ensure everything is working after the switchover, and once off the phone, log into the ActionTec, perform a DHCP Release, and then prompty power off the ActionTec. Once this is done, plug the CAT6 cable into your Valet router's Internet port. You should from this point, be able to connect to the Cisco, and if the DHCP Lease was broken successfully, the Cisco should begin serving up your Internet connection. If it does not, leave the Cisco powered off for a few hours to break the DHCP lease, and then power it up. If the Valet does not work, still, give the Valet a factory reset and set up this router again, with the Ethernet cable from the ONT connected to it.
    I would just take a good luck at the FAQ linked above again, and see what would work the best. Easiest thing to do is to get the ONT moved to Ethernet, which allows you to eliminate the ActionTec unless you need it in the future for TV service, and also allows you to use any router with ease.
    Once the Valet is up and running and holds your Public IP address from Verizon (use http://whatismyip.com/ to determine this) , and also serves up IPs to devices on your network, post back and we can help you set up the Netgear. If you have any issues while setting this up, fall back to the ActionTec. It's factory reset will work without configuration needed, regardless of you being on Coax or Ethernet.

  • Can I connect a second router to the coax cable.

    In my house Verizon fios goes into a box and a coax cable comes out and splits in one direction towards a set top box and in another direction to an Actiontec M1424WR router. An eithernet cable connects the router to a computer. All is well. This works fine.
    Now I want to install another computer next to the TV. It sits a long way from the Actiontec, wireless is flakey and i dread the idea of pulling a long cat5 cable through my attic to connect the computer to the Actiontec?
    Will it work if I put a splitter on the end of the coax in the room with the tv, run one wire to the stb, and the other to a new router?
    Solved!
    Go to Solution.

    Not a second router ... you want to go to your favorite online retailer (like Amazon.com) and purchase an ActionTEC ECB2200 (also called an HME2200) MoCA Ethernet Adapter.    Plug and play and you're all set -- it will automatically link up over the Coax to your ActionTEC router and provide a LAN connection at the second location for you.
    You can search the forums for the ECB2200 / HME2200 and you'll find numerous discussions on this device.
    I use this in my home network setup and it works great.

  • Adding a second time capsule?

    I've reviewed some of he discussion on adding a second Time Machine but two issues arise.  The information relates to older Time Machine software and leads to confusion.
    I have an Airport Extreme with S/W version 7.6.4 and would like to add a newer Airport Extreme to back up the older one.  Reading the suggestions on adding a new TC didn't cover the newer Time Machines and I could find Apple's instructions for doing it.
    Somewhere I read that the new TC could be connected to the old TC but forgot the port setup.  Also, newer instructions for adding a second TC so both the old and the new acquire the same data could not be found.
    Hope This question is clear.  Is there help on this?

    The network setup is fairly trivial.
    Plug TC2 into TC1. (the hardware is Time Capsule.. TC as per your title.. or is it Airport Extreme as per your question..?? Time Machine is software on your computer.. and totally unrelated to the hardware.)
    Makes no difference which way around you do it. Plug WAN of the 2nd device into LAN of the 1st device. And setup the 2nd device in bridge.. wireless is up to you.. off or on?? Roaming or not??
    As far as backup is concerned.. you need to be clear in the question. And sorry it is a bit mixed up now.
    But I can tell you what you cannot do.
    You cannot backup to both units at once. You can however setup Time Machine in the computer to backup sequentially to both.
    See Q34 http://pondini.org/TM/FAQ.html
    The TC itself cannot backup to another TC.
    (extreme with hard disk amounts to the same thing.. with caveats)
    You can backup one TC to another manually via a computer.. it is slow and I do not recommend it.. if a fault creeps into backup1, you are simply copying said fault to backup2.. AND it is poor for another reason.. Time Machine cannot do it.. you will need another utility eg Carbon Copy Cloner.. and even then you will probably end up backing up a huge amount of data every time.. since TM works so strangely you cannot just backup differences.

  • How to Setup a Second Router (WRT310N)

    I have two WRT310N routers.  I am setting  up the second one to extend the wireless range.
    IMPORTANT: THE SECOND ROUTER IS PLUGGED INTO THE LAN VIA ETHERNET CABLE PLUGGED INTO THE INTERNET JACK ON THE ROUTER.
    The IP of the first router is set to 192.168.1.2.  I can connect to it and get to the Internet via wireless.
    The second router is 192.168.1.1.  I can see both SSIDs for each router.  However if I connect to the second router I can't get to the Internet since the Internet port is connected to the LAN, not the Cable Modem.
    Should I be able to setup the second router to use the first router as the Internet connection?
    For Internet Setup I selected Static IP.  IP Address 192.168.1.106 (this is the IP the first router assigned it).
    Subnet 255.255.255.0
    Default gateway 192.168.1.2 (the IP of the first router)
    DNS - I looked up the DNS addresses that my provider is assigning and types those in.  
    Network Setup
    IP Address 192.168.1.1 
    Subnet 255.255.255.0
    DHCP Server Enabled - but I changed the range to start at 200 instead of 100 so it won't conflict with the other router.
    When I try to save I get "The Router IP address equals to the subnet address"
    What am I doing wrong?  Is it possible to setup a second access point when the second router is hardwired to the LAN?  Or do I need to install DD-WRT firmware?
    I'm rusty on my network stuff.  Thanks in advance for any help.

    I think I figured some of this out since your post.  Thanks much.  I found a post on the Internet that said to 1) set SSID on second router to same as the first, 2) disable DHCP on the second router.  
    Works great. This is with the second router LAN connection plugged into the LAN port, not the Ethernet port.  I've got a device that has to get access to the LAN which is now plugged into the second router instead of the wall jack.  I almost thought I was going to need to add a hub so I could split the wall jack between the wireless router and the media device.  But the question is, how can I tell which router I'm currently using for wireless when the SSIDs are the same.  The area I was having trouble getting connectivity to the first router because of the distance, now I get connectivity, but when I had separate SSIDs the other day I noticed for some reason I was able to connect to the first router anyway.
    I suppose I could just unplug the second router and see if I lose a connection.  I'm running Windows 7.  Does the client wireless card just automatically connect to the router with the strongest single when the SSIDs are the same?
    I suppose if I am getting a decent connection on my deck now, I shouldn't worry which router I'm connecting to, but I would like to confirm if the $50 I invested was even necessary now.  Guess I should go unplug the second router and see if the connection strength changes or drops.

  • WRT54GS2 as second router to increase wireless range

    All-
    I have a primary Linksys router, WRT110 that works great. I am trying to set up a WRT54GS2 as a downstairs wireless to increase range.  I have a CAT5 running from the WRT110 to the WRT54GS2 and is connected from LAN to LAN and have them configured as follows:
    Primary WRT110:
    I.P: 192.168.1.1
    Subnet 255.255.255.0
    Start I.P: 10 to 50
    DHCP enabled
    Wireless mode : mixed
    Band: Auto 20/40mz
    WPA2 security
    =================
    WRT54GS2is configured as follows:
    I.P: 192.168.1.2
    Subnet 255.255.255.0
    DHCP Disabled
    Advanced Routing / NAT:Enabled
    Wireless network = Mixed
    Channel = 6 = 2.437mz
    ============
    On both routers I have the same SSID and same security key.
    On the Status page of the WRT54GS2 I have the following:
    Login Type: DHCP
    I.P and Subnet Mask are blank.
    Any ideas where I erred? I've read quite a few posts relating to this and can't seem to find the problem.
    Thanks!

    Is the SSID broadcast enabled on both?
    Is the device "within 15 feet" connected to the first router or second router? What happens if you switch off the wireless on that computer and then switch it on again?
    What happens if you disable the wireless on the first router completely? (Wireless network mode to Off). Can you see the signal of the second router?
    You could also use a network sniffer like Netstumbler http://www.netstumbler.com/downloads/ to scan for networks. It should show you the signals of both access points.
    What are your full and exact Wireless and Wireless Security settings on both routers?

    This is not expected because NAT to internet should still be done by Router1, no? Computer
    behind Router1 with IP 192.168.1.x has internet connection.
    [5] It looks like I cannot change the Routing Table Entry on Router2. I do not think I need to change anything,
    just an observation.
    [6] If I use LAN to LAN connection, then both intranet and internet works. [The internet IP of Router2 can be
    anything not in the same subnet of the Router1, and DHCP on the local side should be disabled to avoid conflict
    with the the DHCP on Router1].

    I have a question. Unfortunately in order to ask my question, I have to have a lengthy description of my setup. Basically, I have a second Linksys router in "router" operating mode with NAT disabled connected to the Verizon router, and I have a computer which is in a different subnet (192.168.2.x) behind the Linksys router. This computer can communicate with computers behind Verizon router in subnet (192.168.1.x), but cannot reach internet. This is a simplified version of my question, full details are in the original post.
    If I setup the Linksys router in "gateway" operating mode, which means with NAT enabled, then both intranet and internet works, but there is no easy way to setup port forwarding for 10 compueters in 192.168.2.x network to communicate with 10 computers in 192.168.1.x network.
    If I setup the Linksys router in a LAN to LAN configuration with Verizon routers, but this way all computers are in the same subnet, I want them to be in different subnet for access control and things like that.
    I hope this makes things a little clear.
    Thanks.

  • Adding a Second Airport Express

    Is there a trick to adding a second Airport Express?  My network is created by an Airport Extreme.  Six months ago, I added an Airport Express to get better coverage upstairs (no problems).  Now I want to add a second Airport Express to extend coverage to the back of our house.  I plug in the Airport Express but it never shows in the Airport Utility.  I have tried over and over and it never appears.

    The second Express can "extend" the signal provided by the AirPort Extreme, but it cannot "extend" the signal from the AirPort Express that is already "extending".
    The Express always needs to be located where it can receive a strong signal from the main router in order to "extend" that signal.
    Might that be the issue here?  The second Express is possibly located too far from the AirPort Extreme?
    If we need to do some more checks, is your Mac runnign OS X 10.6.8 as your profile indicates?

  • Added a second IP to our server = Now users can't log-in

    Hi,
    I had a server that was working fine. It had one external IP address. I then added a second external (dedicated) IP address to the same ethernet port, by adding a second port in "Network Preferences" and manually typing in the IP configuration - just as I did for the original ethernet interface when the server was originally configured.
    The reason I added a second IP address is so that I could run Apache2 on port 80 on the new IP while continuing to run Apache1.3 on port 80 of the original IP.
    Of course now I've screwed up the reverse DNS and such and my users can't login over AFP (though SMB is ok). My initial IP has a properly configured reverse lookup, the new IP does not. The new IP is using the ISP's default domain name.
    In a situation like this, am I supposed to configure both IPs to resolve to the same computer name? myServer.company.com ? Or should each IP resolve differently..
    Thanks

    Of course now I've screwed up the reverse DNS and
    such and my users can't login over AFP (though SMB is
    ok).
    How do the users connect to AFP? WAN or LAN, Hostname or IP ?

    Reverse lookups (PTR records) shouldn't come into it. If users use a hostname to connect then all you will need is an A record to convert the hostname to an IP. If they use an IP to connect, then no DNS is accessed. So if you cannot connect directly using the IP address then it suggests firewall or config - test for open 548 port etc.

  • Can I set up a second router (extreme or express) with WEP while keeping 802B,G,N on the primary router (TC)

    I have a wireless temperature controller which only uses WEP security. I have my TC configured for 802.11 B,G,N which disables WEP. Can I extend or create a new wireless network which uses WEP while maintaining my current network configuration?

    Yes, this is extremely easy..
    Get a wireless router or AP.. anything cheap will usually be fine.. you don't need fancy. And if it is G or B wireless then a second hand is also fine.
    For a wireless router you can bridge it, if that option is available.. usually not.
    So you do a sneaky work around called wan bypass.
    It is easier to give you actual situation.
    TC running standard IP 10.0.1.1
    Set up the WEP router with IP, 10.0.1.254 (puts it outside the range of dhcp in the TC and will never be used).
    Turn off the dhcp server.
    I do suggest you set a fixed wireless channel,, so it doesn't interfere with the TC.
    eg 1, for 2.4ghz.
    Then plug LAN port of the router to the LAN port of the TC by ethernet.
    Voila, you have a secondary AP and can set poor security on it.
    *** DANGER DANGER WILL ROBINSON***
    You have just reduced the security of your whole network by creating a loophole.
    I would strongly recommend turn it off when you finished playing on your Wii or whatever ancient device that uses WEP.

  • I can't get my ICloud started. Each time i try to sign in..it indicates that theres a problem with my email apple address but never indicates what. I added a second email but the same result. Have changed my password numerous times...no result?????

    I have followed the instruction relating to Icloud connection.When i went to system preferences, my Apple address is continually rejected. I have added a second email as suggusted by an Apple site but i still get the same message. Im not told why the Apple ID/email is not accepted when it is accepted in all other Apple sites. I changed my password numerous times to ensure it wasnt the password but to no result. It continued to state that my Apple ID was the problem. I live in Malta,Europe. Have new Apple Mac Pro and Ipod. The annoying thing is that ICloud continually send me the problem notice but do nothing to tell me how to fix it? Can i switch this notice off? Help???????

    Welcome to the Apple community Yao.
    If you mean that Find My Phone is asking for a password to a different Apple ID to your current Apple ID.
    This feature has been introduced to make stolen phones useless to those that have stolen them.
    However it can also arise when the user has changed their Apple ID details with Apple and not made the same changes to their iCloud account/Find My Phone on their device before upgrading to iOS 7, or if you restore from a previous back up made before you changed your details.
    The only solution is to change your Apple ID back to its previous state with Apple at My Apple ID using your current password, you don’t need access to this address if it’s previously been used with your Apple ID, once you have saved these details enter the password as requested on your device and then turn off "find my phone" and delete the account from your device.
    You should then change your Apple ID back to its current state, save it once again and then log back in using your current Apple ID. Finally, turn "find my phone" back on once again.
