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.

we have approx. 70 Cisco 1941W routers deployed in our company. I used to be able to console into the internet wireless AP by issuing the below command:
service-module wlan-ap0 session
However lately this hasn't been working and AP just simply refuses connection. Here is what I have for Status. I have tried reseting the Service Module to no avail.
Router#service-module wlan-ap0 status
Service Module is Cisco wlan-ap0
Service Module supports session via TTY line 67
Service Module is failed
Service Module reset on error is disabled
Service Module heartbeat-reset is enabled
Service Module is in fail open
Service Module status is not available

Suffered a big outage on the network, the fix was to reload the module 3 on the 6509 switch, we had these errors on the log %CONST_DIAG-SW1_SP-3-HM_PORT_TEST_FAIL: Switch 1 Module 3 TestUnusedPortLoopback Port(s)[24,46] failed. System operation continues.in the end, we reloaded the card and it was all ok. is there anything I can do to check the card / or any deeper logs? would that error cause the card to crash?

We have some 1242 LAPs in a two 5508 controller setup working fine. All LAP are configured to obtain address from DHCP. After first join we usually change some configs like HOSTNAME, AP GROUP, PRIMARY AND SECONDARY WLC. After a software restart or a complete power off/power on the LAPs joins the primary controller and all configuration still there. We now add a 1142 LAP and is does not retain the configuration after a power off/power on cycle, but after a software restart there is no problem. The only way to retain the config is setting the AP with a static IP address.
We use WLC 7.0.116 and we see no errors in the LAP console.

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.

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?

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

I have two ACE-4710 in active/standby mode, running code A3(2.2). Four contexts are configured. Both devices were functional without problem, until I reload the standby unit. After reload, the standby unit completely lost its configuration with exception of the FT vlan and the FT peer configuration in the Admin context... Both units recognized each-other and I can still ping the primary unit on the FT vlan, but nothing else. Contexts are lost and interfaces are shutdown! Nothing changed at the software level, both devices run exactly the same image and the same licences are installed (it worked well before the reload).
So, I decided to reconfigure the basics on the standby unit in order to trigger a config sync from the primary. And here arrives the problem : I reconfigure the FT vlan, the FT peer, I check the peer state and everything is OK.
Then, I try to ping the primary unit from the standby unit with success :
switch/Admin# ping 192.168.16.1
Pinging 192.168.16.1 with timeout = 2, count = 5, size = 100 ....
Response from 192.168.16.1 : seq 1 time 0.000 ms

I've a 3945 with SM-ES3G-24-P module installed and tried to configure some routing but it doesn't work .
1. L3 interface on the switch modules (with ip address configured)
2. OPSF on the router with connected interface redistribute (which includes the switch module L3 interfaces)
I don't see any of the switch module L3 interfaces routes in the router, not even the connected interface.

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.

My company has acquired a Catalyst 6513 with a FWSM module installed on it. I have been reading lot of documentation on [URL], but still have some problems configuring the FWSM:
The 6513 has 10 SVIs configured, each of them with an IP address. These 10 SVIs are binded to 10 VLANs which I need to secure. These SVIs are used for routing all the Inter-VLAN traffic inside the switch. The documentation says it is recommended to use just one SVIs for connecting the switch to the FWSM, although you can use more than one using the command "firewall multiple-vlan-interfaces". I don't want to use this command because it seems a pretty more difficult configuration, since you have to use policy routing after using this command (or that is, at least, what documentation says).
When I try to "send" to the FWSM more than one VLAN that are configured as SVIs on the switch I get this error message:
"No more than one svi is allowed, command rejected."
If I delete the IP address of those SVIs, then I can to "send" those SVIs to the switch with no problem at all. But I need the SVIs to have IP address configured, since they are needed for routing Inter-V LAN traffic.
So, the question is: how can I route all the inter-VLAN traffic using just one SVI on the switch? Should I use the FWSM for inter-VLAN traffic routing?

I have a single rule configured for any device that matches tacacs to use the identity source of Active Directory,
If authentication failed: Reject
If user not found: Reject
If process failed: Drop
The ACS can not access Active Directory, when I debug TACACS authentication on any 65k or 2921 device I get "Received Authen status error".

My new RVS4000 (2.0.2.7) connects the WAN via PPoE with dynamic IP which is held at DynDNS and normally I see the RVS4000 via a router-to-router-VPN. That works fine so far, but every "some" days the router looses WAN connection (and with ist VPN). When this happens, last DynDNS-update is hours ago, so it didn`t reconnect. Looking on the routers site, the LAN is fully functional for clients that have got their DHCP-Information. New clients don`t get DHCP-Info (IP-address, DNS), both do not have internet access. The router`s WAN-summary shows, that it thinks to be "CONNECTED" but with empty WAN-IP and DNS entries. Klicking "DISCONNECT" and then "CONNECT" again solves the problem so far. The loss of connection is not the periodic break from the IPC, which is correctly identified and reconnected as configured. I wanted to trace the problem with the log, but there is also a bug. It stops logging at some time completely - neither email-log nor local log, so I never happend to be lucky to hit the point of loss of connection. Also the local log provides a first and next pages, but the next pages are always empty - not really useful.

I have a server (Windows Server 2003) that randomly looses connection with the default gateway and anything on the outside. When this happens, the server cant ping the gateway (A Juniper SSG5 firewall/router) and the gateway cant ping the server. But the server still can ping anything else on the network and everything inside the network works fine with it. The most reliable remedy is to reboot the router. Rebooting the server or resetting the network card sometimes works. I have tried both onboard network cards and a separate PCI network card on the server. There are no router log entries that correspond to the problem. This server is used as a Terminal Server for a remote office and as a file server.

I recently started having trouble with my VPN clients loosing connection.I can create the conenction, work with it for a while, and then loose connectivity.Timing seems to be dependent on the activity over the connection.More activity, the conenction stops working sooner.
The cleint doesn't disconnect, I just can't access anything from the client.Disconnecting and reconnecting the client fixes the problem, temporarily depending on how much data I'm transferring.This works 90% of the time.The other 10% if I wait 30-45 minutes, and try again.. It works...with the same results...
It was originally isolated to a Win 2003 server that I was using as the client.It is now happening on my Win XP client as well.I'm using the AnyConnect client ver. 2.5.2014 with the VPN service on the UC520.Which I beleive, is similar to the ASA 5500 series VPN device.I am running ver 8.1.0 on the UC 520, and I can't remember if this started after upgrading to the new software.

I have copied my computer's time in the router time setup under Time in the "tools" section of the router setup. After a few days of the router being up without a hard restart, it has lost 10 minutes somehow. I went to the logs and cleared them out and then looked at the entry showing that the log was cleared and looked at my computer clock and the time stamp of the log entry, and it was 10 minutes slower than my computer clock that I had originally set it from. I have a clock plugged in by the computer, and my computer always matches the clock that it plugged in, so I know it isn't my computer loosing time. What is going on here? Why does the router loose the correct time after it has been up and not unplugged or rebooted at all? I know that the router will loose the time if you unplug it, but this isn't the case here.

Newly purchased DSC-930L connected to DIR-625. Firmware is 1.0 for DCS-930L and A1-1.09 for DIR-625.Camera works fine when connected with cable. Wireless enabled, fixed IP address.Unplug cable and camera still works fine for a while: can access the view page and view picture that does change. F5 refreshes page no problems. After a while (about 5 minutes) web page no longer reachable by browser. Reconnect cable and works fine, unplug and repeat the cycle same thing happens.Also tried: unplug ethernet cable, unplug power cable, wait 10 seconds, connect power cable, try to browse to camera - cannot reach camera.

I have a DIR-655 Rev B1, FW 2.01 (I will probably upgrade the FW tonight to the latest.)
I have at least 20 items that connect wirelessly to this router (2 PCs, 2 Laptops, 2 Tivo Box, 3 Game Consoles, 3 Cell Phones, 2 Tablets, 2 TVs, Printer, AP Gateway, and some other projects) It's been a solid connection to everything for the past couple of years.
I bought a new Dell Inspiron 15r SE laptop (uses the Intel Centrion Wireless-N 2230 Wifi Solution.) After anywhere from 2 - 10 mins of browsing/watching a video/downloading files the access out to the internet simply stops.
At this point I'm still connected wirelessly to the router, and if I go to the router address I still have access and can login and see the router settings. I check and there's plenty of time left on the lease (days.) Still not getting internet access. Eventually my Laptop will disconnect and reconnect (or I do it manually.) I've performed hard resets of the router, I've had my laptop Forget the network and then reconnect, etc. Nothing has resolved it.
I thought it may be my laptop, but I've taken it to Starbuck, Work, Neighbors WiFi, etc and I don't have any problems staying connected on their networks.
I've had Dell on the line, we connected hardwired, and there solution was to force forget and reconnect to the router, which worked for the 10min he was on the line with me, but then failed soon after, and back in the same connectivity hell

Region : UnitedStates
Model : TL-WR1043ND
Hardware Version : V1
Firmware Version : 3.13.12 Build 120405 Rel.33996n
ISP : AT&T
Every 5 to 7 days my router loses connection with WAN (ISP modem) but connection over LAN is fine. It seems that 1043ND tries to connect to DSL modem from AT&T by username and password (that does not exists) instead of doing Dynamic IP. I understand that AT&T modem is of type of PPPoE but there is not a password or user id and connection must be dynamic. Page 192.168.0.1/logininfo of modem complains that I was trying to login with incorrect user id password. Every time I have to
1- connect the modem directly to my computer so the modem resets.
2- I have to reset 1043ND to factory default, reboot, and connect cables back how they were, Then go to WAN page do a release and renew to get connected to WAN again.

i have a WUSBF54G that will connect to my router just fine. Right when the device is first plugged in there aren't any problems. I can ping my router, I can ping google.com. The browsers all work correctly, etc. But after a while, maybe 30 minutes (it varies) I lose the connection to the internet. I can still ping the router. I can ping other devices on my network. But I cannot ping any websites by DNS name or by IP address and any browser I use won't display any websites. I have other wired and wireless connections on this network that don't have any problems. I even unplugged this adapter and plugged it into a different computer and had similar results. The device is relatively new (maybe a month old, but only used a few times within that month, and the use that it did get is mostly from trying to troubleshoot this issue.) Both computers I have installed the device on are running Windows 7 Ultimate. Both computers have the latest drivers installed from this site:
[URL]
I have a netopia 3000 router and I have checked to see if the problem could be caused by this router but there is nothing out of the ordinary there. All of my troubleshooting has been using the Win 7 "network and sharing center" to connect. I couldn't get the linksys connection tool to work and actually, I noticed after reading this forum that the linksys wifi connection tool doesn't work with win 7 after all so I don't think using the built in win 7 wifi tools would cause the issue. Also, just to clarify, in an attempt to resolve the issue I have tried dynamically assigning an IP address for this connection and also a static IP address. Either method seemed to yield no results. It is a frustrating problem to say the least. I don't want to believe that the adaptor is faulty. As I said it is relatively new. Also, as I mentioned, when I first plug it in it will work correctly for about the first half hour or so before it will stop reaching the internet. I then have to physically unplug the device and plug it back in in order to correct the issue. I was thinking of creating some kind of script that will automatically disable the adapter every 30 minutes and then enable the adapter. I ran into another issue here though. If I disable the adaptor (either from device manager or from "Network Connections) the device will change status from "Not Connected" to "Disabled." So far so good. But then, when I go to enable the adaptor again the adaptor disappears from the list. It's as if it isn't plugged in any more. The only way to get it back is to physically unplug the device and physically plug it back in. How to "Enable" the device without it disappearing from the network adapter list.
