Cisco Wireless :: 1941w Configuration On NAT Network?

Feb 20, 2013

can assist with a Cisco 1941w configuration problem.I have just installed a 1941W onto our network.  It handles the routing of our block of IPs onto the internet through our ISP using 2 x ADSL2+ interfaces.  his all works.  For the sake of privacy, lets say that our block is 100.101.102.128/25.I am now trying to get the 1941Ws Wireless AP working.I have set up the management VLAN on a private range (192.168.1.0/24), the AP on 192.168.1.2 and can now access the AP interface on 192,168.1.2 from anywhere on our LAN.This tells me that the cisco is routing everything to and from the AP on the management network (192.168.1.0/24).
 
I have set up VLAN 2 on the AP, configured it to use WPA, set the key, created an SSID and assigned it to VLAN 2.  I am having some trouble assigning both 2.4 and 5GHz radios to the SSD.  For some reason after setting up everything using the express setup I could not save Beacon Mode unless I disabled Radio1-802.11N5GHz and now I cannot re-enable because the web interface claims that this interface is not enabled for the VLAN... but that's another question.When I try to access the AP, I am authenticated but never get an IP address.  My best guess is that DHCP on the router is not responding perhaps because VLAN 2 is not routing to the main network.
 
The VLan2 interface on the router side is definitely enabled and set to 192.168.2.1.  I have set up a DHCP pool on 192.168.2.1 that is assigned to Vlan2 (I did manually because CCP claimed there was an overlapping region.. even though there wasn't).  I can ping 192.168.2.1 (or any other internal address) from the AP.  VLAN 1 and VLAN 2 are set up the same way (no ACLs, both in in-zone, both with NAT off)So... why isn't the router giving the wireless client an IP address?  Is there a way to simplify the AP so that VLAN 2 routes directly onto my main IP range?
 
As an aside... between CCP not wanting to add a DHCP range (claiming an overlapping region but manual entry worked), the AP web interface's complete lack of responsiveness (it's horribly slow) and the AP interfaces inability to provide a useful error message... this has been THE most frustrating thing I have ever had to configure..  With the rest of he industry making everything easier to use, Cisco seems to be moving in exactly the opposite direction.

Cisco Wireless :: 1941W Basic Configuration Required

Apr 22, 2012

I am replacing a cisco linksys router with a 1941w.
 
I have the 0/0 accepting a DHCP from the ISP then I have 0/1 going to a switch and hosting a dhcp server.
 
Where I have an issue is:
 
A) Finding a way to turn on the wireless and make it use the same DHCP as wired and setting up a user name/wep password
 
B) Turning on the GUI that is supposed to be embedded on this.
 
C) Finding a way to make the DNS point to the default gateway so that I don't have to set the address everytime we move the box.
 
Here is my current configuration, and with it I can get onto the wired network and get to the internet.
 
Current configuration : 4712 bytes

Cisco Switching/Routing :: MGF Configuration 1941W

Dec 27, 2012

I'm currently trying to get up to speed on a 1941W ISR. I belive i have most of the configuration correct based on reading the documents on this site. However, i'm noticing that my lan to lan network performance is very slow. Peaking out about 3mbs. I was reading some documentation that suggested MGF (MultiGigabit Fabric) might resolve this problem.
 
I have a basic setup in my test environment trying to emulate a branch deployment. 1941W connected to a access switch (3400).
 
- I'm getting slow perfomance (thoughput) between the vlans 66,30,10. Will MGF fix this problem? How do i configure it?

Cisco WAN :: 1941W - AP Module Looses Configuration At Reload

Jan 2, 2013

Something strange is happening to my Cisco 1941W. Every time I reboot the router i loose the running configuration of the service-module (Access Point module). The weird thing is that the router's configuration remain the same. I made sure i save the configuration by issuing the wr command on the service module console but still happens. My router's current IOS version is 15.0(1)M1 and my AP's is 12.4(21a)JA1.
 
I also did another test by making sure the startup-configuration was identical to the running configuration and when I reload the router still happens.

Cisco Wireless :: 1941w Can't Access Embedded AP

Jun 5, 2013

Setting up a new 1941w router. Already have another one offsite that's working great. Based the new configuration on the one I have working and can route traffic, etc. My problem with this new one is that I cannot get into the embedded AP to configure. My configuration follows this question. I have checked status of the interfaces and everything is up except VLAN2. I've used the command no shutdown within the VLAN2 interface, but the operational status is still reading down. The admin status is reading up. All other interfaces are up and up. [code]

Cisco Wireless :: Configure 1941w Router AP

Mar 2, 2012

Our boss decides to purchase 1941w Router & he asked me to do the necessary configuration. my knowledge in CISCO router is a CCNA level & i've never configured an embedded AP or ADSL line on a router before.
 
the topology is as the following: as for the wired Network, we have one LAN (192.168.1.0/24) connected to GE0/0 (192.168.1.254/24) on router & has the ability to access the internet which is ADSL configured as ATM0/0/0
 
As for the wireless network ( now here is the problem) what i want is the following:

I want the wireless network to share the same network with the wired which means 192.168.1.0/24 i want to use WPA encryption how to configure the AP?!
 
this is a true challenge for me. After a lot of searching, most of the sample configuration over there is about creating two VLANS!!! & two DHCP Pool.

Cisco Wireless :: Embedded AP In 1941W Router?

Cisco WAN :: Does 1941 (not 1941W) Have Wireless Controller

Aug 25, 2011

I currently have:

- 1941 (not wireless) router
- 1140 Access Point
 
It looks like I got the controller-based AP instead of the standalone.  My question is, does the 1941 (not 1941W) have a wireless controller?  If not, is there a controller module that I can add to my router?  Or should I return the AP I have for the standalone version (or the 1941 for the 1941W)?

Cisco Wireless :: Setting Up Embedded Access Point In 1941w ISR

Jun 20, 2010

I've done quite a bit of work with Cisco kit before (it isn't my speciality, however) and am currently working on setting up the embedded Access Point in a Cisco 1941w ISR.
 
The primary router is working fine, but I'm getting no where with the embedded Access Point. The whole IOS within an IOS just doesn't compute for me.
Our requirements are really simple.
 
We have a 10.0.0.0/24 internal network. We want users to be able to access this via the 1941w Wireless Access Point, in the same way that wired users access this via the Ethernet port.
 
The manual re. setting up the AP gives an example where IP addresses are applied to the AP, which doesn't make sense to me, as we simple want the AP to sit on the same VLAN as the ethernet port.
 
How the AP is supposed to interface with the primary router? Also, we want to use a WPA secret key to authenticate to AP. Is this possible? The Cisco docs seem to suggest that WPA is only possible through some 3rd party server.

Cisco :: 1941W Built-in AP Goes Down?

Dec 26, 2012

how to debug why sometimes the dot11radio0 / 1 go down?  Sometimes, the lights on the router indicating the radio status go out.  Usually, a reload of the ap will bring them back up...Maybe hardware is starting to fail?  Just unsure on how to debug to find out why it turns off sometimes.

Cisco Router 1941W - WAN Keeps Disconnecting Randomly?

Oct 23, 2012

We are using Cisco router (1941W model) and our the WAN interface keeps going down randomly (sometimes happened twice within 1 hour, sometimes worked fine for 2-3 days before getting disconnected). After getting disconnected, if we unplug the cable that connects our router to the fiber terminal and then plug in back, everything works fine immediately.

We had asked our Internet Provider to come 3 times to check the network line, renew the fiber terminal and do some investigations, they said there should be no issue on their side. If it's true then there must be something wrong with the router.

We also enabled ip accounting on the router and saw very low rate of small packets coming to WAN interface.

During the downtime, LAN interface still worked fine.

Cisco Switching/Routing :: Where To Get AP Software For 1941w

Mar 23, 2013

I own a 1941w that is covered by a service contract and I'm entitled to download software for it. But unfortunately I don't see any option to download AP software for it. I need an upgrade for the internal AP to connect it to a virtual WLC.Apparently I need ap801-rcvk9w8-tar.152-2.JB.tar to get this done.I can find it under the 800w series, but I don't own a service contract for that so I can't download anything.

Wireless Network Connection Does Not Have Valid IP Configuration?

I am having a similar problem as others with the "wireless network connection does not have valid IP configuration" explanation. I have a Dlink DIR-655 wireless router and everything was working fine for a very long time, but yesterday the wireless stopped working. After trying a couple of things and having the same problem I reset the router and now I cannot get the wireless to work. When I run the Windows 7 network troubleshooter it comes up with the "wireless network connection does not have valid IP configuration" explanation, but I cannot figure out how to remedy this problem. I foolishly did not save the previous router configuration before resetting the router[CODE]

Wireless Network Connection With Invalid IP Configuration

Sep 1, 2012

Sometimes the router has too many devices connected to it and the other people living with me don't understand this so they keep their iPhones, iPads, laptops, et cetera connected via WiFi even though I tell them to turn off the WiFi setting when they're not using it. So it kicks me off constantly, not sure why, but I don't mind too much. Basically when I'm "connected" but not really connected I remotely reset the router so I don't have to walk upstairs all the time.

I've reset it without troubles before. But did it tonight and now it's completely screwed up. I run a windows diagnostics test and it comes up with: "Wireless network connection doesn't have a valid IP configuration."
