    Linksys 54G wireless Problem

    Had this wireless router for at least 5 years and just lately its gone down.
    It transmits but seems not to want to connect to Internet. Updated firmware
    to DD-WRT successfully. Verizon is my ISP and its setup as DCHP. Is there
    any test I can run to verify that its broke? BTW, I did have a power outage
    a few days ago and the DSL modem went down but all it took to get it up and
    running was a reset. Also reset the router to, but still no Internet. Is it
    just time to get a new wireless router? Think I'll get the same one,(this
    thing has been bullet proof for years and has never dropped signal).. I've
    been hearing really bad reviews on the N wireless routers unless you spend
    over $150.00.... Running Linux and Apples.

    Never mind the wireless. What happens when you plug your computah
    into an ethernet port? Got connectivity? Can you ping the router?
    Can you ping the ISP gateway?

    >Updated firmware
    >to DD-WRT successfully.


    What exact version of DD-WRT?
    What hardware version of the WRT54G? (See serial number tag).
    There are firmware versions that have problems and combinations that
    don't work too well.

    >Verizon is my ISP and its setup as DCHP.


    So, go unto the status page. Did Verizon successfully give you a DHCP
    assigned IP address, gateway, and DNS server?

    >Is there
    >any test I can run to verify that its broke?


    No. However, there are some tests you can run to verify that it's
    working. As previously mentioned, take the wireless out of the
    picture and check just the router to internet connection with ping. If
    that fails, plug your computah directly into your DSL modem and try
    pinging from there. If you have a spare computah, you might use that
    to verify that your Linux/Mac/whatever is working.

    Incidentally, check the wall wart power supply. I've seen some
    failures. Some get really hot and partially fail (check with
    voltmeter). They're easy to recognize as the white label usually
    turns brown from the heat.

    >BTW, I did have a power outage

    Reset like in punching the reset button on the modem? If you had any
    saved settings, they're gone now.

    >Also reset the router to, but still no Internet.


    DD-WRT doesn't really respond to the reset button. It can be disabled
    in the firmware. Since you also shuffled the deck by doing a firmware
    upgrade, you might want to do the reset to defaults from the web based
    menu.

    >Is it

    It's 9:30AM. This is a bit early to go shopping. Perhaps later in
    the day.

    >Think I'll get the same one,(this

    WRT54G boxes are fairly good, but not all versions. V5 and V6
    hardware are useless junk (not enough RAM for the full DD-WRT). V7 is
    based on an Atheros chipset that doesn't like DD-WRT. Some versions
    have non-removable antennas:

    Hopefully, you've been reading such things as hearing voices is a
    symptom of too much computing and RF. I have my own opinions about
    802.11n. Basically, if you want or need speed for things like
    streaming video or local machine to machine file transfers, 802.11n is
    what you want. However, you don't get speed for free. You lose range
    and reliability with increased speed. So, if you want a stable,
    reliable, but modestly fast connection, stay with 802.11g.

    Works fine through the DSL modem. Once the wireless is connected no
    internet.

    Yes I know but think the only thing I need to reset was the bridge on the

    Ok, so you have connectivity. When you switch between a direct
    computer to DSL modem connection, to installing the WRT54G in between,
    please power cycle the modem so that it picks up the MAC address from
    the router.

    >Once the wireless is connected no
    >internet.


    Read what I wrote. Please forget about wireless for now. Do your
    testing with a CAT5 cable from your computah to the router. Once
    that's working, you can work on the wireless part of the puzzle.

    >> What exact version of DD-WRT?


    >Firmware: DD-WRT v24-sp2 (10/10/09) mini


    1. Don't use mini. That's fine for an initial load, but I'm very
    suspicious of the mini version, which doesn't get as much testing at
    the STD version.

    2. As John mentioned, there are problems with some of the
    "recommended" firmware versions. What's your build number? John
    recommends build 12533. I just checked a few of mine and that also
    the built I'm running. Except for erratic PPTP VPN disconnects, it's
    stable. Incidentally, I'm not using STD. I prefer NoKaid so that I
    pickup a few KBytes more working RAM.

    >WRT54G V3.1


    Good hardware version. That should work fine.

    It also doesn't seem like I'm getting through.
    IP address, netmask, gateway, and DNS. You just supplied the IP
    address. Go to the web page config.
    Status -> WAN
    You'll find the numbers at the top of the page.

    That's weird. I've seen that before but can't recall the cause.
    According to Cisco, that's caused when:
    The interface on which the packet comes into the router
    is the same interface on which the packet gets routed out.
    or
    The subnet or network of the source IP address is on the same
    subnet or network of the next-hop IP address of the routed packet.
    and some other stuff that's specific to Cisco IOS. I would guess it's
    the first, which is a wiring error. My guess(tm) is that you have
    both the DSL modem and the Linux box plugged into the LAN ports on the
    router. Did you or someone juggle cables just before the router
    failed?

    >Yes I know but think the only thing I need to reset was the bridge on the
    >DSL modem.


    Yep. Now, if I knew the make and model of the DSL modem, I might be
    able to confirm that it's really a bridging type DSL modem, and not
    the usual AT&T supplied DSL modem with a crude form of NAT that screws
    everything up. I have no idea what Verizon normally provides.

    >Loaded DD-WRT after the power spike.


    Ok. Did you RESET the router after you loaded DD-WRT? That's an
    option when you install it. I've had problems moving config files
    between versions. I sometimes have to clear the router and re-renter
    everything from scratch by hand (not from the previous config file).
    This sucks, but that's what was necessary to make things work a few
    times.

    That's the most likely explanation in a 'simple' topology like a home
    broadband connection. The fact that you get a new nexthop of the address
    you're trying to ping implies you're in the same subnet as your
    destination. Have you perhaps plugged the LAN and the WAN in the wrong
    way round?

    not true you can get a good N router for around 100.00 (US) I paid about
    100.00 for a D-Link D655. Works great.

    Hi,
    Ditto on DIR-655. I liked it very much when I had it. Moved onto dual
    bander of different brand with dd-wrt.
