Cisco 1800 dot11radio0

    I have an 1800 cisco router with a wireless antenna that randomly
    drops at least once a week and stays down for a random duration.
    USually around a several hours, then comes back up.

    If I do a "sh ip int brie" it shows my dot11radio0 as being "reset". I
    have never seen an interface actually stuck in a "reset" mode. Usually
    when you do "sh ip int brie" the interface is either up or down.

    Any clue as to why this client wont auto reconnect back to the AP
    router? Here is the config on the interface.

    IIS-R0#sh run int dot11radio0
    Building configuration...

    Current configuration : 259 bytes
    !
    interface Dot11Radio0
    ip address 192.168.254.2 255.255.255.252
    !
    encryption mode ciphers tkip
    !
    ssid SSI
    !
    speed basic-1.0 2.0 5.5 6.0 9.0 11.0 12.0 18.0 24.0 36.0 48.0 54.0
    station-role non-root
    antenna receive right
    antenna transmit right
    end

    One other thing that really confuses me is the use of a "Virtual-
    dot11radio0" interface which seems to be completely nonprogrammable
    from the CLI. What is this virtual interface and why is it even being
    used? If I have to use it why cant I program it from the CLI? I always
    found the SDM to be awfully limiting.


    sh ip int brie shows
    Dot11Radio0 192.168.254.2 YES NVRAM
    up up
    Dot11Radio1 unassigned YES manual administratively
    down down
    Virtual-Dot11Radio0 192.168.254.2 YES TFTP
    up up

    Any help would be truely appreciated!

  2. Cliff,

    Do you have an HWIC-AP-AG-A or HWIC-AP-AG-B? If the former, you might want
    to take a look at:

    CSCsk21362 c2811 hwic-ap radio enters reset / down state

    If this looks like a match, you should open a TAC case.

    Aaron,

    Thank you So much for helping me. I'm not sure what version of HWIC I
    have. It's built into the box thats all I know. Is there a way to tell
    what type of HWIC I have remotely? WHen I do show interface it doesn't
    tell me anything of the sort.

    I tried to run a google search on "CSCsk21362 c2811 hwic-ap radio
    enters reset / down state " and couldn't find anything relevant.

    was this at the CCO site?

    Thanks Aaron

    The command to see the hardware configuration is "show diag"

    Bugs can viewed on CCO using the "Bug Toolkit", located in "Support Tools".
    If you don't have a CCO account you may not be able to view the bug or
    download a new version of IOS that resolves this issue.

    These are not different "versions" as such but
    are different part numbers and I would expect the
    number to be printed on the outside of the WIC and
    to be visible without removing the card. (in very small
    letters due to the restricted space).

    Also look at sh inventory, sh hard, sh controllers,
    if you are still having trouble.

    Sometimes SNMP can reveal information about
    the cards in a box - the older software seemed
    quite poor at displaying it from the command line
    in some cases. With recent software sh inv seems
    pretty decent.

    And a whole lot more. I omitted the rest because it is very lengthy. I

    The Hwic is literally built into the system. I couldnt pull it out

    Can I register for a free CCO account or do I need to get setup with
    some type of maintenance plan with Cisco?

    1. what is the exact model of 1800 wireless router ?
    - 1801, 1802, 1803, 1811, 1812, 1841

    The routers are Cisco 1811w's.

    Here is a link to the antennas we are using.
    http://www.radiolabs.com/products/antennas/2.4gig/backfire.php
    Radio labs says they think we have a router problem.

    IIS-R0#sh inventory

    Cool antenna


    AFAIK the 1811W has internal mini-PCI radio card(s) i.e. you do not
    have an HWIC-AP based radio

    These radio cards may be the same one used in the Cisco AP 1200

    The source of your problem may be the radio firmware so you could try
    upgrading the IOS version
    n order to get a newer version of radio firmware.

    Please post the output of show version

    Cisco have discontinued the model of router that you have and have
    replaced with

    I suspect that what was changed was the radio card.

    See EOS/EOL for Select Cisco 1803W and 1811W ISRs and Cisco 802.11g/a
    High-Speed WAN
    http://www.cisco.com/en/US/prod/col.../prod_end-of-life_notice0900aecd8066a188.html

    Do you have a Cisco Smartnet support contract for the unit ?

    If so you should contact the Cisco TAC and inquire whether Cisco will
    replace the radio

    Next time this issue happens do a shut/no shut on the radio interface
    and see if connectivity is restored.
    If so I would tend to suspect that your problem is fhe radio firmware.

    This is for a client so I am not sure if they have a support contract.
    They bought these routers from a previous consultant. Paid 1k a piece
    for these guys. They bought these after July, I believe. I cant
    imagine he would sell them something that was EOS/EOL, especially at
    that price.

    My company doesn't have a cisco maintenance contract yet. Most of my
    clients have had Juniper equipment. While I am decently familiar with
    cisco equipment I am not an expert, ye..t. I actually had hoped to get
    more cisco carrying clients in the future. Running into problems like
    this is discouraging.


    Last time the wireless died I ran shut/noshut on the interfaces of
    both the Root and the non-root router. I rebooted the router. Changed
    the signal channel on the root side because I thought maybe it was
    interferance. I have my CCNA and am descently comfortable with jumping
    around the CLI. No matter what I did when the router would come up
    that interface would constantly just get stuck in RESET mode. Then
    after a random 30 minutes or longer it would just come back up without
    warning or reason.

    I think your idea on this router may be true. If this router is
    discontinued then this could be a valid reason why. Looks like we just
    got stuck with some trash.

    Reading between the Cisco lines and the bug mentiond
    earlier is seems quite likely that you are hitting
    the bug.

    You have the dash A device.
    CISCO1811W-AG-A

    You need a login to see the bug. It appears that the only fix is
    to use the -B. The bug mentions ONLY the HWIC and not your
    specific hardware. Smartnet for an 1800 won't be much.
    I would imagine that cisco would replace the hardware
    in this case with the -b if you had support or were in warranty.

    ohhhhh - that does not sound good.

    are there two 1811W in this setup ???

    I think the EOS annoucement was made in June 2007

    Your client has until June 2008 to get a service contract if they do
    not have one.
    Without that they will not be able to upgrdde the IOS software.

    Yea, it's a bridge and the routers are acting as the bridge. One is
    root, the other non-root. They are the only two devices that connect
    to this wireless network. I have verified that by constantly checking
    the associations on the root side. I will have to talk with them about
    t he service contract. I really really really appreciate your time
    merv. If you have any more ideas just let me know and I can get
    whatever information I am capable of off these routers.

    Diagram really helps - thanks

    Is this issue happening on one or on both of the 1811W's ?

    How many antennas are attached to EACH 1811W - one or two ?

    If one - when looking at the unit from the rear - which side - left or
    right - is the single antenna attached ?

    Are they both running the same IOS version ?

    OBTW another option for your client might be just to pick up a used

    The issue actually only happends on the Non-root. The root never goes
    down, I am wondering if this is due to the basic nature of a root AP.
    At least so far as we have seen the root has yet to go down.

    Each router only has 1 antenna and I am not there physically to see
    which side they are on. If you think its relevant I can find out.
