Two WRT54G routers One DSL Connection?

Thank you for reading my request.
Situation:  I have one Internet connection and I have need of two networks.  One filtered with OpenDNS and the other unfiltered.  I have a Speedstream DSL router provided by ISP for connecting to Internet.  I have two WRT54G's and would like to utilize them to form two networks.  The Speedstream is a router with a gateway address of 192.168.1.254.
From that Speedstream (only one network plug) I would like to go to a 5port switch.  From that switch, I would like to configure the two WRT's to be two different networks (one using OpenDNS settings for filtering) with one having a 192.168.1.x address scheme and the other (no Internet filtering) having a 192.168.10.x scheme.  Both would have DHCP enabled for their networks and the Speedstream would have DHCP disabled.  There is not a need (at this point) to have the networks communicate.
Is this possible and if so, is there some semblence of a walkthrough for it?
Thank you again for reading my request.

Yes, this setup is possible. As long as the modem will be able to support more than one connection, then you may connect the 2 routers thru the switch. 
The only thing that I see as a possible concern is about double NATting. If ever there is a need for you to open any ports in the router, then you will have to do double port forwarding or open a port in both the router and modem.

    how to configure one dsl connection and one public ip in cisco router and map to one interface for using exchange server

    Hi ,
     Have you got any additional public IP Address from your service provider , If yes on router you can have static route for those additional IP Address pointing to your ASA  outside interface . 
    Accordingly you can configure NAT

  • I have two iPads and one is connected to the internet but my other iPad was connected then was not and since then I have not been able to add my internet back onto my iPad it only says cannot connect to the server any help would be great thanks

    If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
    First, test your iPad on some other WiFi networks: a friends, Starbucks, Barnes & Noble, etc.
    If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
    If your iPad does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
    If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

  • Two Macs - only one can connect to Airport at a time

    Starting today, after 10 days of successful operation, when I came home I couldn't connect to my home (new "square" Airport Extreme) network with my Core 2 MacBook Pro. My wife was happily connected on her PowerBook G4.
    Puzzled, I tried a few obvious things:
    Airport OFF, Airport ON ... no joy
    Logout and back in ... no joy
    Restart ... no joy
    Then I turned my attention to the Base Station:
    Restart ... nope
    Change to "None" security ... nope
    Change back to "WPA Personal" ... nope
    Humbled, I stopped and had dinner. My wife's G4 went to sleep, my Intel went to sleep. Now it gets interersting! My Intel woke up first and immediately joined the network -- I'm happy till I hear my wife say SHE can't get connected.
    To make a long story short, I have two laptops on my desk, and only one can connect at a time! This is BIZARRE. Turn off Airport on either one and its buddy gets a connection immediately, and vice versa. Sleep the connected one and the other connects.
    I am out of ideas.
    Errors on the G4:
    Feb 28 20:09:45 localhost configd[35]: WirelessConfigure: 88001003
    Errors on the MBPro:
    various 88001006 errors as reported by others in this forum.
    Both Machines at all the latest updates; the MBPro has the new Extreme software installed from the CD that came with the new hardware.
    I would welcome suggestions ...
    MacBook Pro Core 2   Mac OS X (10.4.8)  
    G4 Cube   Mac OS X (10.4)  

    Software Update is not offering me any Airport updates on the G4 (or the Intel).
    The recent Airport Update, "AirPort Extreme Update 2007-001", is of course only for Intel Macs.
    They could only be "trying to use the same IP address" if they were not configured to use DHCP, but they are configured to use DHCP, and whichever connects does get an address in the 10.0.1.[2-200] range so I think that's not the problem.

  • Two Cisco Routers in one class-c network

    Hello,
    i have two cisco routers, which are connected to one switch. On this switch, there are several servers connected as well.
    When i connected the second cisco router, i got messages on the first router, that there is an ip address conflict. After a few minutes it seems as if the vpn tunnel on the first router breaks down because of this conflict. I'm not sure about this, but when i disconnected the second router again, the vpn tunnel could be established again. The vpn tunnel goes to another router via WAN and ends in the local class-c network, where both routers are in.
    Router1
    LAN 192.168.105.254 (255.255.255.0)
    WAN 212.xxx.xxx.xxx

    Cisco Switch

    Router2
    LAN IP 192.168.105.253 (255.255.255.0)
    WAN IP 217.xxx.xxx.xxx
    Router1

    ip address 192.168.105.254 255.255.255.0
    Router2
    int fa 0/1
    ip address 192.168.105.253 255.255.255.0
    Could the /24 mask on the interfaces cause the conflicts?
    From the servers, none has the ip 192.168.105.253 or 192.168.105.254 and if i disconnect Router2, the IP 192.168.105.253 is not reachable from any system on the switch.
    So how does this ip address conflict occur?

    hello,
    can you check the router 1 log. with error message you should have a mac address
    May 10 05:32:20.489: %IP-4-DUPADDR: Duplicate address 10.10.10.1 on GigabitEthernet0/1.1, sourced by 0003.oc12.a2c3
    This should help you to identify host already with 192.168.105.253.
    Before connecting Router 2, from Router 1 ping 192.168.105.253 and do a sh arp ?

  • Help, Issues Connecting two Wireless Routers

    Ahead of time I would like to thank everyone for their responses and help. I tried to be as clear as possible. I believe I got all the details right. Some things are repetitive and might be a little confusing,  but please ask questions for any clarification. Thanks  for the help. 
    Current Routers:
    1. Linksys WRT600N ---- Used as primary router. Connected to the 4 ports are 3 PCs and a wireless router. All three PC have static IPs I reservered, also have a static IP reserved for the WGT624 wireless router. DMZ is also enabled and destination is the IP reserved for WGT624. 
    2. Netgear WGT624 ----  WGT624 is connected to WRT600N through  the WAN port on the WGT624 to port number X on the WRT600N . I was using Netgear WGT624 as an access point for a Xbox360 , a couple of macs and  ubuntu netbook.  This router recently died needs to be replaced.
    3. Linksys E3000 ---- Recently purchased to replace the Netgear WGT624 that has died. I want to use this as my new access point. Having trouble setting up the settings for this router. I want the same setup as before. 
    Detailed Problem
    I currently have the WRT600N located in the basement connected to a cable modem through the WAN port. Connected to the 4 ports on the back of WRT600N are 3 PCs and a Wireless router. Most of the settings on the WRT600N I left alone. The only thing I changed was reserving 4 IPs for the 3 PCs and the WGT624 wireless router. I also enabled the DMZ for the destination IP of the WGT624.  I also opened a couple of ports.
    The Netgear WGT624 that died was located on the upper level third floor. I was using it primarily as an access point. It was connected through the WAN port  of the WGT624 to port X on the WRT600N which is located in the basement. Settings on this are a little different. On the WGT624 I disabled the firewall. I left both the Auto DHCP enabled and the DHCP server. WPA was enabled on the WGT624. With these settings on the WGT624 I was able to connect to a xbox 360 and a few macs wirelessly to the internet with no issues .  I also noticed that the the internet IP displayed on the status tab on the WGT624 was the IP I had reserved on the WRT600N.  
    Recently the WGT624 died after  years of usage. So I purchased a Linkys E3000. I want to have a similar setup as before with the WGT624. However I have been running into issues. Wirelessly I cannot get access to the internet through the E3000. The E3000 is connected to the WRT600N in the same was as the WGT624. The WAN port of the E3000 is connected to the port number X of WRT600N.  On the status tab of the E3000 I seem to be getting a strange Internet IP address. 127.0.0.1. This I think is a loopback address, I am not sure? Same with the subnet mask of 255.0.0.0
    So the problem is I want the keep the same setup as before if I can. I don't want to the any computers who connect to the access point to have access to any computers that are connected to the 600N.
    I read on another thread I could connect two wireless routers together by connecting port X on the 600N to port X on the E3000.   Then changing the internal IP of the second router from 192.168.1.1 to 198.168.1.2 and then disabling the DHCP server.
    I really want to keep the same set up as before if posslble. More importantly I want to know why my setup prior, the WRT600N  to the WGT624 worked with no problems. Why could I use the WGT624 as an access point and not the E3000? Should I switch the the two routers use the 600N as the access point and E3000 as my main router?
    Thanks again.

    1. You have chained two routers. The WRT600N uses LAN IP address 192.168.1.1 subnet mask 255.255.255.0. The Netgear is connected with the WAN port to the WRT (thus uses an 192.168.1.* address on the WAN port) and uses 192.168.0.1 by default on the LAN side. Your new E3000, however, uses the Linksys default 192.168.1.1 on the LAN side. If you connect the E3000 to the WRT600 without making any changes it won't work. A router cannot work if WAN and LAN side both use 192.168.1.0/255.255.255.0. That's impossible.
    2. Thus, the quick and easy setup to get the same as before would be to change the LAN IP address of the E3000 from 192.168.1.1 to 192.168.0.1. After that change you can connect the internet port of the E3000 to the WRT and everything works like before.
    3. However, in particular because you need port forwarding and you do port forwarding through two routers I would recommend not to run two routers chained. I can't see why it is necessary for you to run two routers and two separated networks. The basic setup and an explaination why a different setup may be better is here. I think in your case it would make things much simpler and you have full connectivity between all your computers. You can set up a roaming wireless network, too. The only problem is that you will "loose" one port on the E3000 because you cannot use the internet port.

  • One Internet Connection, Two different LANS & Two DHCP Servers, How to share internet without conflict?

    I have two LANs and one internet connection.  Each LAN has its own DHCP server.  I want to be able to have internet access on BOTH LANs but don't
    want to have a DHCP conflict between them.
    The main LAN is a Time Warner Cable modem and a Cisco router running DHCP going to a 48 port switch that has all the workstations connected.  
    The second is a stand alone Windows 2012 WDS server which is ONLY use to image computers via WDS. The server is running DHCP as well and is connected to another 48 port switch where I connect systems that need to be imaged.
     I want to be able to provide internet access on LAN with the Windows 2012 WDS server so after I image the computers I can download drivers direct from the internet.   The Windows WDS server has two NIC cards but I am only using one.   Is
    it possible to configure this so the internet from the main LAN is shared to the WDS server and its clients without causing problems with the two DHCP servers?   Here is a basic network diagram.   Thanks!

    Hi Adam,
    To share the internet on secondary VLAN, please follow the steps below:
    Connect the secondary switch to Cisco router
    Configure the devices on secondary VLAN to use Cisco router as its' gateway
    Configure NAT for secondary VLAN on Cisco router
    Due to different manufacturer has different ways to configure, for detailed configuration information, please consult the manufacturer of the switch and router.

  • Using two wireless routers for two separate networks

    I have one WRT54G router and a newly purchased E2000 router that replaced the WRT54G . I have one DSL connection coming into the house.
    I have the DSL going directly into my main E2000 router which runs my existing wireless home network and it does this wonderfully. My son wanted the older WRT54G router to create his own network where he has it set up for his own purposes so I gave it to him. He has everything set up to where we have two functioning networks that do not conflict which is great however he ran an Ethernet cable from the e2000 to the WRT54G to make this happen. This cable is a problem since it basically is about 50 feet of ugly cable running up my stairs to his room. Is there a way to have the routers still work in tandem as they are now to manage two separate networks but to instead have them connected wirelessly and eliminate the existing wired setup?

    You would need a third party firmware like DDWRT to do that (it will void the warranty too)
    Or you need a wireless bridge like the WET54G or WAP54G set to bridged mode

  • Daisy-chaining two WRT54G's

    Hi, I was wondering if it would be possible for me to use two WRT54G routers in line in a certain set up.
    The first WRT54G is currently on the first floor connected to the cable modem and this what is now used for my home wireless network... and with this I would like it to remain operating in that capacity.
    I have a second WRT54G that I would like to put on the second floor (hardwired to the first one with a single 100' ethernet cable) to be used as a "switch" that I could hardwire two gaming PC's to. I don't really have any concerns about the second unit providing any sort of wireless network support. as the first unit can reach every device in my home with full signal.
    I was told that this is entirely possible to do. But I just have no idea how to go about setting it up. Is it as easy as just wiring it all together and powering up? Or will the second router require some modification to make it operate correctly?
    I sketched up a (crude) diagram to show what I'm looking for

  • WRT54G routers losing settings...

    I'm seeing some weirdness.
    I have two WRT54G routers.
    The main one is connected to my cable modem, and pretty much runs with factory defaults - other than the password being changed.
    The second one is used to extend my wireless range. It is connected to the first one through one of the main ports (not the internet port) and is configured to use IP 192.168.1.2, and with DHCP turned off.
    They work fine. Mostly.
    But every once in a while, the modems spontaneously lose their memory and are reset back to factory defaults. Which causes problems, as both modems think they are the ones in charge, and I have to go through and reset them both.
    Any idea what is causing it?
    I'm running v1.00.6 on both of them.

    hi .....only one option here.....upgrade to firmware version 1.01.0 on both WRT54G's

  • Connecting two WRT54G wireless routers - how to configure

    Hi All,
    I have two WRT54G wireless routers. One is currently providing wireless access for several users at a local law firm. I need to connect a second wireless router for a user who works for another company in the same office. The second wireless router is basically going to be used for Internet access. The Office Manager at the law office does not want the user from the other company using their wireless router directly, BUT they will allow me to hook up the second wireless router for Internet access. I realize this doesn't really make sense in terms of security, but this is the scenario I must abide to. So I am wondering how to configure the second router. I am thinking that I connect a CAT5 from one port on the first router to the Internet port on the second router. I am also guessing that I need to assign the the second router a static IP with a different subnet such as 192.168.2.1. I am not sure if the first router still has the default 192.168.1.1. If the first router does use 192.168.1.1 would I need to change the IP on the second one to one on another subnet? Thanks.

    You will need a setup like this:
    Modem  ---  new WRT54G  ----  existing WRT54G
                     192.168.2.1              192.168.1.1    ( "Local IP address" )
    Modem connects to Internet port of new WRT54G.
    LAN port of new WRT54G connects to Internet port on existing WRT54G.
    SSID:  different on each router  (do not use "linksys" )
    SSID broadcast:  enabled on both routers
    encryption:  recommend WPA2, or at least WPA  (can be same or different on the two routers).
    passwords:   different on each router.
    channel:  try to stay at least 5 channels apart.  Usually channel 1, 6, and 11 work best, but any two different channels can be used.
    Any "port forwarding" used by existing WRT54G must also be done on new WRT54G.
    Both routers need a real login password (not "admin" )
    New WRT54G will need "Intenet connection type" set to whatever is currently on existing WRT54G.  Internet connection type for existing WRT54G will need to be set to DHCP.

  • CALLING ALL EXPERTS - Connected TWO Actiontec Routers to use one as main and second as GUEST

    Hello Experts-
      I have TWO Actiontec Routers from Fios. I bought the new N one, and I have an old Actiotec that I was previously not using.  So here is what I am trying to do...
    I'd like to leave Router 1 (the New N router) as my primary router (comes from ONT via cat5 wire NOT Coax) and Set-up the second router off the first to be a guest router.  So essentially make it a bridge.
    I can't seem to configure it to work correctly.  
    Can anyone out there give me a step-by-step walkthru on how to configure this second router so I can have them both hooked up, seperate SSID, with one as the Main and the other being the Guest?

    THANKS IN ADVANCE!
    Rob
    To change the IP address of the Local Area network choose:
    My Network
    Network Connections
    Click edit on the row for "Network (Home/)office"
    On the next screen click Settings
    On the next screen you can change the LAN (192.168.1.1) address to something different.
    On the same screen you can disable DHCP too.
    I hope this helps.

  • Connecting two routers to one internet connection, one with dynamic and the other static?

    My father uses a BEFW11S4 router with firewall  for his home office. It uses a Dynamic IP. I have my computer up stairs and the internet conenction is set up through the router via wired connection. The problem that I have is that in order for several of my online games to work, (Final Fantasy XI and the Playstation 3 network) I need to add Port codes to the router to gain access to the online features in the games. To add the port codes to the router, I need to change to a Static IP.
    My father does not want to change to a Static IP and so I am unable to connect to the online services that the games provide.
    Is it possible to connect another Router to the same internet connection? This one would be a static IP.

    Ok well My father's computer is wired and so is mine. My ps3 is wireless. My father needs the dynamic IP on his computer or he will not be able to use the things needed for his work. I need the router to be Static so that I can play the games. So What you are saying is that I can still use 1 router and have both dynamic and Static IP set up at the same time of the one internet connection?

  • Three WRT54G Routers on one subnet

    I support a tcp/ip network that has three WRT54G Routers on a cat 5 backbone which are all on one subnet 192.168.2.96/27. There's one WAP54G configured as a wireless repeater for a sales area in the corner of the office where there's no drop. The internet connection is provided by Comcast via cable modem. The office manager purchased the routers because they were cheaper then the WAP54G Access points and the cabling was already in place. There must be a real tight budget there. I configured Router1 (WRT54G) as a gateway to the Cable Modem and enabled DHCP beginning with octal 105 leaving 8 ip addresses for static and 22 for DHCP devices. The other two (Router2 and Router3) WRT54G's I've disabled DHCP and enabled them as Routers instead of Gateways with RIP disabled. The WAP54G Repeater has the wireless MAC Addressed of Router1's in its Repeater settings and has no cable to the network.
    Since all DHCP devices on the network have its default gateway set as Router1, everyone is able to get on the internet. While I was configuring the network I noticed that it didn't matter if I made Router2 and 3 routers or gateway as everyone appeared to be working okay and were able to get on the internet but in the setup it says to enable Router for all devices not directly connected to an internet connection. I'm guessing that this might make a difference only if I had two different subnets in the office. Since Router2 and 3 are basically dumb to the internet gateway, they can't see anything beyond their own ip address and just pass packets back and forth almost like a repeater.
    I guess my question here would be, is there any advantage of using the WAP54G over the WRT54G as an access point when wired to cat 5?
    Message Edited by donwoodsnet on 12-04-200605:06 PM

    I guess you have connected the WRT54Gs through their LAN ports and the internet port is empty. That's the way how you use them as access points.
    If you connect them that way the gateway or router mode is irrelevant. The mode only works between the LAN and WAN. They did not design the WRT really for use as access point with an open internet port and therefore this is not documented in the help file. I would leave the setting on gateway as then it is a setting less to change back in case you must use it as gateway later again. If you use router mode, make sure RIP is disabled. The router is not working as router thus it needs no routing information...
    Regarding your question: the answer is only the obvious one: except for the more extended configuration options in the WAP I don't think their is an advantage for either one.

  • Two WRT54G, two networks, same Internet Connection

    If anyone can take the time to educate me in how to effectivly stack routers to share one internet connection but set up two different networks I would really appriciate it.
    I want to set up an open wireless network for customers but have my POS and Cameras on a seperate network that people using the wireless cannot access.  I have two routers, and have tried using different subnets but cannot get it to work. 
    Is there any step by step instructions on linksys's site?  I cannot find them.
    Any help is greatly appriciated.

    Thanks for taking the time to reply.
    I have one WRT54G v5 and one BEFSR41(sorry don't know the version).
    Right now I have the BEFSR41 acting as the router and the WRT54G acting as a wireless access point.  I have a hardwire connection going from port 1 on the BEFSR41 to port 1 on the WRT54G and have DHCP disabled in the WRT54G.  Right now anyone connected wirelessly to the WRT54G has full access to my network.
