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!

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
can paste it here again if you like.

The Hwic is literally built into the system. I couldnt pull it out
unless I took apart the entire case.

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


2. also post output of show inventory

do you have a high-grain antenna attached to the right receiver ?

The routers are Cisco 1811w's.

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