I still believe that the best thing to do is to open a case with TAC about this problem. But if you do not want to open a case for some reason then upgrading the IOS would be a reasonable thing to do and would probably resolve the problem. I have been running 12.3(11)T8 on 1841s with reasonably good success.

Trying to print from my iMac to a Cannon MG5320 will not print. Started having problem when new Wifi router??? was installed Cisco. Keep getting A Communication Error

Problems printing form iMac to Cannon MG 5320. Just had new Cisco router installed and problem started. Keep getting communication error

To address this problem, I suggest that you do a complete reinstall and setup of the printer as if it were brand new. It is preferable to do this from the original CDs that came with the printer. I think the printer has to set up again to connect to the new router.
The Canon web site has for this printer a "mini-master setup" file you can download that has the same setup program that came on the CDs.

Problems connecting to a Open Network via Wi-fi on Cisco Router

Hi everyone, I know I'm new here but I'm in need of your help, so if you can assist please do so as I cannot live without wi-fi and might have to go back to my nokia again if I can't sort this out.
Vodafone finally released the Iphone on their network in Ireland today and I've picked a 3gs up straight away.
At work I have a wi-fi network with a CISCO router (I have no access to the router as only IT do and they won't change anything to satisfy me and my Iphone anyways). This network has no encryption whatsoever and its free to join, you don't need any password or anything. My nokia at the start couldn't connect as it said that the network needed a pre shared key, this isn't true and in the end it was just change a setting to no auth required for it to log into the network and work perfectly.
Today I got to work and the Iphone can't connect to the network, just says it can't join the network. I cannot find anything about authentication on the settings of the phone nor can I work around this at all. I've had a Ipod touch for (the 2nd gen) for over 2 years and I gave up trying to set it up at work because I just couldn't find what was wrong with it, I ended up almost not using it other than when traveling or on the gym.
So first question is there any way I can access the authentication settings for wi-fi connections on the Iphone? Maybe its just a little change that is needed like the nokia.
Has anyone experienced this problem on a open network that they cannot join?
Any other sugestions? Anything really?
Thank you very much for your time guys, I would really really appreciate your help on this.
Regards,
Rod
PS: I've also tried to install the Iphone configuration utility however I don't know how to access the profiles on the phone, anyone can help with this so I can try the profile I've created?
I don't think it is going to work because the options available on the configuration utility are basicly the same available on the Iphone itself.
Anyone has any sugestion on how to solve this problem??? Thanks very much.

I am getting an un expected error message when updating the setting to "extend network". Is there an obvious setting I may be missing? Cisco router being used.

I am getting an un expected error message when updating the setting to "extend network". Is there an obvious setting I may be missing? Cisco router being used.

If you are trying to "extend" using wireless only, you may not be aware that Apple designed the "extend" feature as a proprietary setting to only work with other Apple routers.
It is extremely unlikely that this will work with a Cisco router.
If your plans call for connecting the AirPort Express to the Cisco router using a wired Ethernet connection, it should be possible to configure the Express that way.

If I understand your question correctly; no, there are no IPs configured by default.

WLAN - Probleme bei Cisco Router WRVS4400N-EU

Hallo,
ich habe bei einem Kunden 2 Cisco Router WRVS 4400N-EU. Dort gibt es Probleme mit dem WLAN. Wenn ich eine Verschlüsselung einrichte, setzt der Router nach ein bis zwei Wochen das WLAN auf Werkseinstellungen (Standard SSID und Unverschlüsselt) zurück, andere Einstellungen sind nicht betroffen und nach einem Neustart des Geräts lässt sich das Gerät wieder konfigurieren.

Leider nicht.
Unser Kunde hat die HW gegen ein anderes Model ausgetauscht!

Problem installing hp 8600 plus to laptop after installing wireless on desktop via cisco router!

After installing the printer successfully on my desktop wireless through the cisco router I attempted to add my laptop a hp G60-635DX notebook. After installing the printer I got a message that a driver cannot be found! I called cisco and they offered online help for a $ 69.00 contract for 1 year! Looking for cheaper alternative!!!

Does the Asaro run DHCP? If so, turn off all access points except the one running DHCP and connect the printer. Then you can turn on the other APs.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.
I am employed by HP

Problems with my 1760 cisco router

Is possible to conect to Internet a 1760 Cisco router without VIC/WIC cards? My Cisco router don't have this cards and I am not able to understand his role in my network! (school network). Thank you.

Depends on your internet connection. If you use DSL/Cable Modem, you usually get an ethernet hand off. If you have T class connection, you'll have/need a WIC-1T or WIC-1T-DSU.

How do I setup Airport Express to extend my CISCO router's wifi range?

Hi,
I am using CISCO EA4500 router for internet connection via wifi. I have Airport Express with me, which I want to use as extender of the wifi network. I setup the Airport Express as "Extend the wireless network", provided same base station name (CISCO), network name (JKS) and passwords.
However, I am not able to get it to work. Its gives me error saying network: unknown.
I have just 1 BHK flat, and even then the range is not enough to reach from my DR to BR. I tried using Airport Express as the base station as well. But the problem is again the range.
Help me please.
Jayesh

Can I do it other way around? I mean setup Airport as Base station and use Cisco to extend the wireless network?
I doubt that the Cisco router would be able to to wirelessly extend the AirPort network, since Apple uses proprietary settings that are designed to work with other Apple routers.
Also, when I am trying to use just Airport, I am not able to connect multiple devices at the same time
Sorry, but I don't know whether you have the AirPort connected to the Cisco router using an Ethernet cable....or.....whether you are saying that you have the AirPort connected directly to your modem using an Ethernet cable.
If the AirPort is connected directly to your modem.....what is the make and model number of this device?
Since you know that the Cisco router is working OK when you have it connected to your modem, things would be much simpler if you connect the AirPort to the Cisco router using an Ethernet cable. Can you do this?

Encapsulation dot1q is not working?, 2600 Cisco router

     I am trying to config a 2620 Cisco router to perform subintreface (F0/0.1) for Vlan Trunk Protocol, however when I try to configure the encapsulation dot1q, I continue to receive error massage with ^ symbol below the 'c' See below, the platform version is a 12.3(26) which should be acceptable to perform an (encapsulation dot1q). The Ethernet is a fast-Ethernet 10/100 port. I also try the ISL, I receive the same massage.
Can anyone suggest what could be the problem!!
Thank you all!!!!!

It's possible your feature set it not good enough to run trunking.
Trunking apparently requires a minimum of the IP PLUS feature set according to this document
http://www.cisco.com/en/US/tech/tk389/tk815/technologies_configuration_example09186a00800949fd.shtml
table 2 shows a minimum IOS of 12.0(1)T and IPPLUS/IPPLUS on the 2620 - so your IOS revision is OK, but maybe your feature set is not.
You can figure which feature set you have by going here
http://tools.cisco.com/ITDIT/CFN/Dispatch?act=rlsSelect&task=search&searchby=image
and entering your image name (assuming it's not been stuffed with) which you can find by doing "show flash" or "dir"
If you don;t have the right feature set, then you're out of luck unless you can upgrade/change the IOS image the router is booting with.
Cheers.

Trouble connecting Cisco router with cable modem for Internet purposes

So I am requesting help from the Cisco community on this issue as the cable company states there equipment is working fine. At all my facilities I have a guest Internet service setup through a local Internet provide to provide Internet services to the residents and guests. I have the cable modem usually a Motorola SBG6580 or a SMC 8014 (both provided by cable company) connected to my router on a FE or GE interface. I am using static IPs and using the cable modem just as a modem (bridge mode). Over the past several months these connections have just stopped working. I have not made any drastic changes to my router configs; however, the cable company has updated the firmware on these modems. I am wondering if that could affected how the modem and router talk. I was told by the cable company that the modem sees the Cisco router but that the port is inactive. My router shows the port is active and traffic passing. Does anyone have any ideas that could point where the problem lies? I will post a basic config to one that currently does not work. I am using a VRF to route a certain group out, using NAT. Please let me know if I need to post additional info. Any help would be greatly appreciated.

Let me know if you need anything else. I need to figure this out and I just don't get it because the other site wasn't working a few days ago and all of a sudden it is working again but others are still not.

PXE boot via Cisco router

We have a need to netboot a PC with Linux via a Cisco router (I.E. PXEboot).
We have copied the PXE linux.cfg files to the Cisco router's flash, (Cisco 2821, IOS Advanced Security 15-1.2-T1).
We have setup the router as a TFTP server with defaulted path as tftp-server flash:tftpboot
From the pc's CMOS, we selected PXE boot.
With "debug ip packet detail", we can see the DHCP request from the PC.
We cannot however, get the router to download the Linux files to the PC.
Manually we tried:
c:\ tftp 10.0.0.1 get default - no go.
ANYONE have an idea????
Thanks
Frank

Hi Ash,
Thanks for the assistance.
The laptop is directly connected to the Cisco 2821 routers g0/0 interface.
The router is configured to be a DHCP server with the Cisco 2821 router IP address on g0/0 set in the DHCP configuration to be the default router. The router’s IP address is excluded from DHCP. (10.0.0.30)
If the laptop’s bios is set to PXE boot, it seems to receive an IP address from the router I.E. 10.0.0.1– verified by statically assigning another pc IP address 10.0.0.1– the 2nd pc receives an error of IP address conflict. Then set the second pc to obtain its’ IP address via DHCP, and while running debug ip packet detail on the router, I see the router running through the DHCP assignment process and finally assigns the 2nd pc 10.0.0.2.
So needless to say, I believe the DHCP setup is functioning correctly.
The problem we have at this point is nailing down the TFTP-server function running on the Cisco 2821 router.
We were able to create the directory tree on the Cisco 2821 routers flash and then copy the correct files into each directory within flash.
Using WinXP DOS prompt, tftp does not seem to function.
With debug ip packet detail running on the router and Wireshark running on the PC, we run from a DOS window c:\tftp 10.0.0.1 GET \default. No matter how we specify the path, end result is an error of some kind.
We watch debug and wireshark display the communications of the PC and router talking, but cannot seem to get the requested file.
Perhaps WinXP tftp server is flawed.
If we load TFTP32 and attempt to send and/or receive a file from flash, works fine.
The router tftp config is as:
tftp-server flash:/tftpboot/dsl/pxeboot.cfg
The actual files name is "default" and is found on the Cisco 2821 flash:/tftpboot/dsl/pxeboot.cfg directory.
No ACLs on the Cisco router and the router is pretty much right out of the box.
Firewall is disabled on both PCs.
Ping to/from the PC/router works fine.
Thanks again
Frank

IDS shunning - IDS can't blocking via Cisco Router

Hello all.
I've configured IDS to shun with cisco router. I think all of setting fine, but IDS can't configure acl on the router via telnet.
Here is the output from ids using sh statistics networkAccess.
if you see the output, the state is Inactive.
Could you please let me know why the state is falling down inactive..
regards,
John.
IDS# sh statistics networkAccess
Current Configuration
AllowSensorShun = false

AclSupport = uses Named ACLs

This means the sensor had a problem either connecting to or reconfiguring the router.
What to do:
Configure network access to Disable Shunning and apply the changed config.
Now configure network access to Enable Shunning again and apply the changd config.
This will cause the network access controller to disconnect from the router and try to connect again.
Check the network access statistic and see if it is still inactive.
If it is then execute "show events past 00:10:00 to see all events in the past 10 minutes. Find the status event where you applied the change to Enable Shunning again, and start looking at the later events. Search for error or status events that might show what errors the network access controller was running in to.
Typical causes: Wrong username or password. Sensor is not able to telnet to the router because either the router is not reachable from the sensor IP, or the router does not have telnet enabled, or the router's access list prevents the sensor from connecting.
Other things you can check:
Create a service account on the sensor.
Login through the service account.
From the service account try to telnet to the router using the same username and password configured in the network access controller configuration on the sensor.
And see if you can get into the router.
You might also try running a sniffer between the router and sensor and monitor the connection. You can look for any error message coming back from the router, or at least see where in the connection the sensor is stopping.
