LINKSYS - WRT54GS Problems, Can't access the internet via LAN

Discussion in 'Wireless Internet' started by omariqbalnaru@inbox.com, Jul 26, 2006.

    I use a lan connection to connect to the internet. I wanted to share
    that connection between a desktop and laptop so i bought a LINKSYS
    WRT54GS. I plugged that LAN cable into that Internet Port of the ROUTER
    and did all the configuration but still can't access the internet. Can
    anyone please help me? It doesn't even works on the host computer...

    Is the WAN (Internet) side of the Linksys being configured properly?
    What IP address is it getting? Subnet mask? DNS servers? Gateway?
    What connects your LAN to the Internet?

    Do you mean the PC which is directly connected to the router? How can i
    tell it is being configured properly? I am not allowed to get
    administrator knowledge about the network so i don't know what connects
    my LAN to the internet.

    Can i solve this problem by using my wireless router as a wireless
    access point?

    Then how did you get permission to do this? Many (most?) network admins
    would consider this a rogue access point and a serious security risk.

    That issue aside, you can tell how the router is being configured by
    what gets displayed in the configuration interface.

    Run IPCONFIG /ALL on a connected computer to get the other info I asked
    for, copying and pasting the exact output here.

    My guess from what's probably going on is that you probably want to
    configure the WRT54GS as an access point, not as a router, as described
    in the HowTo wiki below. At the very least, this should give you the
    same kind of access you have now with your computer when wired. Whether
    or not you can add another wireless computer would depend on what kind
    of LAN security is in place.

    Another option is to add a wireless client adapter to the (presumably
    wired) desktop computer (instead of the WRT54GS) ; create an Ad Hoc
    wireless network between the desktop and the laptop; and share the
    desktop Internet connection with the wireless laptop using Internet
    Connection Sharing on the desktop.

    p.s. Please don't switch posting styles (top vs bottom) in mid-thread
    -- it's confusing, and considered a bit rude. Thanks.

    This output shows that your computer is behind a NAT router, so you
    definitely want to configure your WRT54GS as an access point, not a
    router. That's covered in
    <http://wireless.wikia.com/wiki/Wi-Fi_How_To#Use_a_wireless_router_as_a_wireless_access_point>

    Is this a company / corporate / academic LAN? If so, you should ask
    your administrator for assistance - in many jurisdictions attaching
    your own unauthorised wireless devices to LANs you don't own is a
    /criminal/ offense and can certainly get you fired / suspended.

    However: forget about the Internet port on your router, you don't neee
    it. Connect your PC and your existing LAN to the LAN ports on the
    router, turn off any DHCP server in the router, and give both it and
    the laptop fixed ip addresses in the 192.168.1.x range (but not ones
    used by any other computer on your lan - if you use one from another
    computer, you will break their connection and /definitely/ get in big
    trouble).

    Even this may not work. Many company LANS assign IP addresses only to
    registered authorised hardware.

    I connected PC and my existing LAN to the LAN ports on the router. But
    now i cannot access my router's configuration. The Problem is that the
    default LAN IP of the router and the DEFAULT GATEWAY of my existing LAN
    connection are the same by default. How can i now access my router's
    configuration?

    Configure the router with only one PC connected to it. It's also a good
    idea to change the default configuration of your other router. For a couple
    of reasons, one being avoiding hack attempts due to predictable defaults.
    But also to avoid precisely this problem you're having now from happening in
    the future. If all your devices are setup using DHCP this should be quite
    simple. So move the default router to a new subnet, renew your leases
    through it, reconfigure the new router, also moving it if necessary.

    But if you're using the 2nd router as an access point, not as a router, then
    it goes on the same subnet, albeit with a different IP address. Then the
    'main' router does all the DHCP and routing work.

    I followed Bill Kearney's advice and connected only one PC with my
    router using one of its LAN ports but now i am getting limited or no
    connectivity with that. I can't even access the configuration of the
    router now. What to do now?

    Plug your existing LAN into the WAN input of the wap router, instead of just
    the router part... hould work fine (both wired and wirelessly) that way...

    Do you mean to plug my LAN into the WAN input of the router and then
    connect the PC with the router using one of the LAN ports? That way i
    was facing DOUBLE NAT problems.

    Yes, you'd certainly be setting up a double-NAT situation. Surprisingly a
    lot of things work OK through this, and others can have their ports
    configured to pass as well. But in this particular case there's no need for
    that. When you plug a WRT54G from one of it's LAN ports to the LAN port of
    another one you're essentially adding it to the source router's network. If
    you 'dummy up' the second router (turn off DHCP and the like) then you've
    got yourself the equivalent of an access point. Or you could load the
    dd-wrt firmware on it and get a real access point, either solution works.

    The trick being that in order to program the routers, and have them both on
    the SAME subnet, you'll have to configure them so they don't conflict with
    each other.

    Err, wait a minute, is there more than one router in this setup? That is,
    you're currently getting internet from the wall via wired ethernet, right?
    That being the case then the above applies.

    But as has been mentioned elsewhere, do you actually have permission to be
    doing this? Have you checked with whoever runs this network and confirmed
    that it's OK for you to go adding a wireless device to it? If you have then
    you better check with them FIRST. Adding a wifi router like this opens up
    security issues that whomever runs the network might be VERY concerned
    about. While it's nice to think you can just connect this harmless little
    box to the network and take care of your little problem, it may cause quite
    a few MORE problems, both for you and the network.

    Otherwise, it's technically feasible to do exactly what you're asking and
    has been explained here in this thread (by myself and others) quite
    completely. If the instructions aren't clear then perhaps you shouldn't be
    mucking about with devices like this...

    Connected HOW? If you connect a PC to it, on a LAN port (not the WAN port)
    and it's been reset to factory values then you ought to be able to use your
    web browser to reconfigure it. A router set to factory defaults ought to
    come up on http://192.168.1.1 and automatically hand your PC a DHCP address.
    If it doesn't, then you could set your PC's IP address manually and an arp
    record to point to the router. But if the router's been reset to defaults
    you really shouldn't have to do any of that.

    So, have you reset the router to defaults and connected via a LAN port? Try
    more than one LAN port and try more than one cable just in case there's
    something wrong with them. If none of them work then it'd sure sound like
    your router's got hardware problems.

    As for 'accessing the internet', one step at a time. Get the routers
    configured properly FIRST and the internet connectivity will follow.

    Plug the LAN into the WAN port, and from the #1 port on the wap/router, plug
    to your PC (config by wire is usually on port #1), then when you do the
    config thing (192.168.1.1) , just turn OFF the DHCP server, and in config,
    just make it a router only (ie it asks if you want it to be a server, a
    router, or a server and a router... say router only)...
    IE PC was plugged into the lan, take that wire, plug it into the wan input,
    and the cable in the wap/router box goes from port one of the wap/router to
    your pc..

    Thanks to all for your help. I have understood so far that what i have
    to do is to connect my exisiting LAN into the WAN port of the router
    and then connect my pc to one of the LAN ports of the router. Then just
    turn of the router's DHCP server while configuring it and it should
    work fine. Is it all or there any additional steps too?

    That's all for a start and to get it working.. As some other people have
    said you may have restrictions by IT, and that will allow a totally open
    node which most IT people frown on... But at least it should get things
    working...
    PS On your main config screen, a little ways down is the field "DHCP Server"
    then a clickbox for enable and disable... Select disable...
