Cisco 1800 dot11radio0
Cliff
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.

One other thing that really confuses me is the use of a "Virtual-

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.

Havent gotten a response from any one over there, so if anyone can
help me here I would truly appreciate it. Thanks guys.

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

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?

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
NAME: "chassis", DESCR: "1811W chassis"
PID: CISCO1811W-AG-A/K9, VID: V03, SN: FTX1123Z0W6
Merv
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
IIS-R0#sh inventory
NAME: "chassis", DESCR: "1811W chassis"
PID: CISCO1811W-AG-A/K9, VID: V03, SN: FTX1123Z0W6
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/collateral/routers/ps5853/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.
Cliff
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 ?
Merv
OBTW another option for your client might be just to pick up a used
1811W on ebay - use it for parts or backup
Merv
Please post "sh run int dot11radio0" from the other 1811W
Cliff
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.

Well one test that you might want to try is to reverse the station
roles and see if the problem follows.

Thats an interesting idea. It hasnt crashed in over a week. Maybe this
weekend I can go in and make those changes...
