Changing Wireless Channel on CISCO Router

How do I change the wireless channel on a CISCO 1811W (MPC8500) router? Currently it is channel 10 and I prefer to change it to channel 1 to reduce interference with microwave oven. I have already replaced the standard antenna with 7dBi high gain antenna.
Out of 12 wireless clients about 3 are being dropped whenever microwave oven is turned on. These clients have Linksys WMP54G Wireless G PCI adapters. Other client computers are notebooks with builtin wireless adapters and desktops with Belkin, TRENDnet, or Motorola Wireless PCI or USB adapters.
All computers are within about 60'-80' radius from the CISCO wireless router and are about 20' away from the microwave oven. Any suggestions?
Thanks.

I tried in SDM and could not find a way to change radio channel.
How do I invoke command line interface (CLI)? I found the following from Cisco Wireless ISR and HWIC Access Point Configuration Guide.
Configuring Radio Channel Settings
Step 1          configure terminal                     - enter global configuration mode
Step 2          interface dot11radio 0                   - enter interface configuration mode for the radio interface. The 2.4 GHz radio is radio 0, and 5 GHz is 1.
Step 3           channel frequency | least-congested - set the default channel for the wireless radio - Channel 1 2412 MHz, Ch 2 2417, Ch 3 2422, etc.
                                                                      - To search for the least-congested channel on startup, enter least-congested
Step 4          end                                        - return to privileged EXEC mode
Step 5          copy running-config startup-config          -(optional) save your entries in the configuration file.
I need help to enter into the privileged EXEC mode. Once I type https://10.10.10.1 (router IP) I get a login screen (Level_15 or view access). Once I enter User Id and Password I get Cisco Router and Security Device Manager (SDM) that has Home, Configure, and Monitor tabs.
Configure - Interfaces & Connections - Edit Interfaces & Connections - DOT11Radio0 shows status as Up; but does not allow me to change anything. Neither channel nor frequency is displayed.
So I not sure how to use SDM to change the default channel.
I will appreciate any help in this regard.

How to change the channel on your router.

> this is for 10.7.4
Open Airport tuility on your comtpuer
where to find it > : Applications folder > utilities > airport utility
Clicked the apple router > click the edit button
Clicke the wirless tab at the top and choose wirless options at the bottom
Clicke dthe sutomatic beside 2.4 GHZ and change it to the channel you want it.
Channels 3/4/5/7/8/9 are usually pretty open.
If you not sure what channels are on what network you can review the other networks and your own in system proflier for your comptuer.
once you choose the channel click save and then update at the bottom right.

I am sorry
when you type in 192.168.1.1 in the address bar of the IE..It will Be Prompting you for a Username and Passwd.Try Only The Passwd As admin. . .
If You changed the passwd of the router the first time when you were trying to set the router with the cd and in case if you have changed the password at that time then type in that password in the passwd field. . .
Then After you login into the Linksys Setup Page,
Goto Wireless and try changing the Channel Of The Router. . .
ThankYou

Changing channel on my router

I have a E1000 cysco Linksys router and I would like to change the channel, not sure how. I have a wireless headset for gaming and play online games, when I plug in the headset, I get booted off the internet. I'm looking to change the channel so the router and the headset aren't competing for the same bandwidth. The headset I'm using is the Ear Force X41 and I play Xbox live. The headphones i bought are wireless, my router is wireless.
How do I change the channel?

Welcome to the Cisco Home Community.
To change the channel of your router, Type 192.168.1.1 on your browsers address bar and log in. (Default credentials is to leave username blank and type admin as the password.)
Then click here.

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.

WRT54GL: setup suddenly won't let me change the wireless channel anymore

I have a Linksys WRT54GL version 1.1. The firmware is 4.30.11 (European version).
In the Basic Wireless Settings I can't change the Wireless Channel. It remains at channel 1, and I simply can't alter it.
This is strange, because in earlier firmware versions, I was able to change the channel without any problems at all. I would like to continue to use this firmware version. How can I solve this problem?
Thanks in advance, Pjotr.

Not a browser thing; I tried Firefox, Epiphany and Konqueror. I found the solution, however!
Apparently a small bug in the firmware, but it can be circumvented. Changing wireless channels becomes impossible when in the Advanced Wireless Settings, SecureEasySetup is disabled.
So all you have to do to change wireless channels, is to enable SecureEasySetup. You have to keep it enabled, however: disabling it after a successful channel change, reverts the wireless channel to number 1 again and keeps it locked again.
For the time being (until Linksys fixes this bug), I will have to be satisfied with channel 1. Because I dislike the one-button-security thing SES, and I prefer to define my own security manually. Also I fear an accidental button-pressing.... :-)
Thanks anyway for your assistance.
Greetz, Pjotr.

I changed the channel on my Belkin Wireless router now my ipod touch 1G can't find my wifi network?

A few hours ago I changed the channel on my Belkin Wireless router for the 1st time. It was either on auto, or channel 6 before, i'm not sure, but I changed it to 11, and now my ipod touch 1G can't find my wifi network. I tried changing it to 6, but nothing, and I also can't go back to auto. Can someone please help. I've already searched for the network, and it says "Cant find network". I've also restarted my router. I also added the MAC address, still nothing. Other than those things, I havent touched anything else. My ipod could connect before just find. My Wifi is not disabled, and it's not on private. I can connect with other wifi's fine. And I can connect to other networks with my ipod, I also held down the button on top, and the home button for 10 seconds to restart and nothing. I also reset my network settings. Please help!

Find the documentation for your router and look up "Reset to Factory Defaults." This process will put the router back to the way it was when you bought it.

How do I identify the ports to open on my cisco router from Rogers to allow access through my apple tv - I am not using wireless!

I only have spotty access at best through m Apple TV to itunes, netflix and utube. I am Rogers subscriber (feel my pain) and am now using their CISCO DCP3825 router. Apple TV purchased this past Christmas. I am not using wireless. No issues prior to replacing my old router and Rogers modem to go to DCP3825.
Apple TV is up to date - updated by connecting to my Macbook Pro.
Rogers tech support was of no help - suggested I open some ports - where do I go for the list(s)?
Any help would be much approeciated.

Cisco Valet M10 Wireless channel selection question

hello
Not sure if anyone knows or not, but I'm wondering how the option under the router wireless confirguration page, channel selection operates?
My Valet m10 (firmware: 2.0.03) offers an option to either manually set the wireless channel or have it set to 'Automatic' and I was wondering that when the option is set to 'Auto' how often does the router change channels.
Does it change only after being restarted?
Or does it change periodically all on it's own?
thanks
Solved!
Go to Solution.

How auto channel is supposed to work is that the router does a wireless survey and figures out which channel is best at the current time to lower signal interference between channels.
On some routers this feature doesn't work well and setting the channel manually is best.
Please remember to Kudo those that help you.

Can I run a cat5 cable to a 4 port hub from a cisco router then connect one of the hub's output ports to an airport express to 'extend' my wireless range?

Can I run a cat5 cable to a 4 port hub from a cisco router then connect one of the hub's output ports to an airport express to 'extend' my wireless range?
Flow would be
Cable modem---->cisco e2000 wifi router (This is broadcasting wifi but not strong enough)---->4 port hub ---->airport express (to extend the wifi in another part of house)
thanks!

Yes, you can do this as you stated. In essence you will want to configure both routers for roaming network. Please check out the following Apple Support article that describes this type of network. Although this article uses two or more AirPorts, it can be done with just about any manufacturer's router.

I have a Cisco router and purchased a 1st generation airport, would like to find outbid I could connect the AirPort Extreme wireless with a USB wireless, so I can connect to be able to put the airport in another room to beagle to have it close to stereo

Wireless non-cisco router with aironet 1242 repeater.

Hello everyone. I'm a newbie here. I just started learning about cisco devices. Sorry if my question seems stupid.
I have a problem. A friend gave me an AP aironet 1242 and he wants to use it as a repeater for his wireless non cisco router.
Is this possible? And if it is how can i do it with simple steps.
Thanks in advance!

Thanks for the quick response Scott. I 've read this quide before i post.
The problem is that i can't connect with serial to the ap. So i can't use commands.
I can connect with ethernet and see the ap interface. When i go and make the radio0 work as a repeater it shows interface down. What i want is simple steps of how to configure it from the interface.
Sorry again.

EA4500 - How do I change the email account the router is associated with in Cisco Connect Cloud?

I have an EA4500 runnign the latest firmware that supports the Cisco Connerct Cloud and I need to change the email account the router is associated with. How do I do this? (Online Help does not explain.)

jrosenbl wrote:
We plan to deploy over 350 of these routers across the country. In our situation, it would not make sense to associate all these routers with one email account or even, at the other extreme, a separate email account for each router. In addition, you have created a management nightmare for us if we pursue this option, because anytime we need to make a change to the email account associated with the router, we would need to re-configure it manually. We need to manage these routers separately and outside of the Cisco Connect Cloud option. I understand that I can downgrade the firmware to the prior release, but this is a temporary fix (eventually security vulnerabilities will be discovered that will force a firmware upgrade - in fact, you have already had one) and I would like to request an option to manage the router outside of the Cisco Connect Cloud email associations. Will this be possible in the near future? Otherwise, we will need to consider another vendor for this project.
Hopefully this should be possible in the future.
I believe that I can make it

Hi. Does anyone know how to extend the airport express and extreme with Cisco Router DPC3925. I have upgrade my wireless to 50Mbps. Thank you

Hi,
Can someone help.
I have a Cisco router DPC3925 provided by the ISP and I cannot extend my wireless with Airport Express.
Also I intend to extend it with Airport Extreme.
Please help.
Thank you.

Sorry, but your post is not clear. The topic of this thread is how to extend an AirPort Express or AirPort Extreme with a Cisco router.
This would mean that the main router was an AirPort device and the Cisco would be extending the existing network provided by the AirPort.
Is that really what you want to do?
If not, then it sounds like your Cisco ISP provided wireless router is your "main" router and you will be using the Time Capsule to extend the network.
Please start another post to tell us exactly.......
What device will be the main router providing your Internet connection and wireless network
What device will extend the network
What operating system that you have on your Mac or PC

WRT54G Wireless G--Pressed Cisco Logo by Mistake

I've had my WRT54G working perfectly with my home network, now I was dusting off my computer and by mistake pressed the Cisco Systems button on the router. It started to flash bright white and then stopped. I haven't reconfigured my router in awhile so do I have to start remembering how to reset my passwords etc. I called Linksys and they wanted to sell me an extended warranty in order to help me deal with a possible reset where the router might be looking for a new firmware after pressing this button. So far the router and my settings are fine.

If you press the Cisco Logo on the Router, this will change the Wireless Settings on your Router.... It will create a New Wireless Network Name and a New Security Key....If you want to change the settings on your Router follow the setps bellow..
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...(If you have changed the Router password you can use that password to login to the Router setup page).
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Wireless channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select TKIP...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be more that 8 characters...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

Wrt54g laptop wireless modem connected to router but will not access in any browsers.

I started a friends laptop at my house put in the security key and it connected to my network with excellent strength. When I opened IE or Safari it said unable to access page not connected to the internet.
I went into the properties of the wireless modem and checked to see if it matched my wireless laptop. It was slightly different with not all the same options. I changed something and now I can not get it to connect at all.
I hooked the friends laptop to my lan line and it works perfectly of course, so I know it has to be in the settings.
Any answers to the first problem of browsers not connecting, And anyway you can help me get the friends laptop settings back to where they were?
Thanks

Connect a computer to the Router, Open the Setuppage by 192.168.1.1 , password "admin"
Click on the Wireless tab on the Setup page- Here Wireless Network mode
should be mixed- Provide any non linksys network name ....
Name (SSID) box- Set wireless channel to 11- And wireless SSID
broadcast should be Enabled and then click on "Save Settings" >>
Now Click on the Sub tab under wireless > "Wireless Security" Change the
Wireless security mode to "WEP"...and put a 10 digit key in key1 and keep a note of the key and click save settings ...
Then on your laptop try to connect to the netwok with the key.
