Release Interface Loopback Pseudo - Interface 1 / System Do Not Find File

Oct 31, 2011

I share a modem and router with my building, and connect to the internet using an ethernet cable which plus right into the wall in my apartment. When I hover over the network/internet icon it tells me that I have a local connection only and can't get online. No changes were made to my computer between it working and not working - I have not installed any new software and the modem+router have not been changed.

When I try ipconfig/release is says it can't perform the operation while the media is disconnected. It also tells me that "an error occurred while releasing interface Loopback Pseudo-Interface 1: The system cannot find the fie specified".

Cisco WAN :: 1841 - VPN Options With 3G HWIC Card

Aug 19, 2012

I've been given an 1841 with a 3G HWIC card installed to test with.  I need to set up some sort of VPN to our ASA, the problem is though these 3G cards get a random public IP, so what options do I have to create a VPN tunnel from this router to the ASA without the 1841 getting a static public IP?

Cisco WAN :: HWIC-2SHDSL Disconnection With ATM Interface

Jul 13, 2011

I have a scenario where multiple branches are connected to Head Office via DSL links. The branches are located in differenct exchanges, everyone once in a while ALL branches go down at the exact same time except 3 branches and those 3 branches don't have ATM interface on the router, rather they have external DSL modem, all other branches that face the disconnection (for couple of minutes) have either HWIC-1ADSL-M or HWIC-2SHDSL and the DSL line is directly plugged into the card. [code]
 
I tried so many solutions like adding "operating-mode auto" command under the subinterface, IOS upgrade, changed dynamic routing protocol from EIGRP to OSPF... Nothing worked, on the logs of the router it just shows "EIGRP neighbor down", at the time of the problem I can't ping any of the affected branches on their WAN ATM interface although it stays physically "up up".Could the problem be a missing command that I need to add under the subinterface? Something maybe related to clocking or timeout or..?Note that hte problem occurs randomly, every few days, sometimes every 10 days, and all branches with ATM interface go down at the exact same time.

We want to terminate new 10M link via Ethernet interface on Cisco 1841 router. We have free Gig port on the router. We also have HWIC-FE module inserted in the router. However, our implementation team said that Cisco 1841 doesn't support 10M link. It is not designed to cater to such high Bandwidth.

Cisco Switching/Routing :: 1841 - Router's LAN Facing Interface Becomes Up / Down Frequently

Nov 14, 2011

We have a 1841 Cisco router for one of our remote sites and we have the GRE over IPSec tunnel on it (with our datacenter router) for the connectivity. The LAN facing interface becomes UP/Down (status 'UP', Protocol 'Down'). When I login the router and 'shut' and then 'no shut' the interface, the interface becomes UP and everything starts to work. Traffic starts to flow across it. But after some time, some hours or sometimes some days, the interface is again back to up/down status. The router is connected to  a non-Cisco switch. I do see some CRC's increasing very slowly, but apart from that there seems nothing wrong with the interface in sho int fas0/0 command:
 
!
RTR01#sho int fas0/0
FastEthernet0/0 is up, line protocol is down
Hardware is Gt96k FE, address is 0026.cb91.ee48 (bia 0026.cb91.ee48)

Cisco WAN :: 2811 HWIC Switch Cannot Be Configured As A Network Interface

Apr 14, 2012

I currently have a Cisco 2621 powering a network at our  co-location facility... It's a simple setup and is working well. The colo  provides a redundant HSRP uplink, so I have their two uplinks going into  a Dell switch. From that Dell switch I have a uplink into  FastEthernet0/0 on the 2621, configured with my routing network, and  then FastEthernet0/1 gets an address from my block of routable IP. FastEthernet0/1 then plugs into another  Dell switch where I have all my servers connected. The servers get public routable IP addresses and use the address on FastEthernet0/1 as their default gateway.
 
It's time to upgrade off the 2621, so I aquired a Cisco 2811 which has two FE interfaces, as well as a modular HWIC-4ESW switch. My question is, can I get rid of the Dell Switch A in the setup above and just use the internal switch on the 2811 to accomplish the same thing? And I if I did this, would my two uplinks from the colo plug into ports 1 and 2 of that HWIC, and then port 3 would physically connect into FE 0/0? Or can I logically do that via configuration in the Cisco? I'm not sure how all this works and haven't received the new router yet, so I thought I'd get a head start and reach out to the experts.
 
My second question is unrelated, but each port on the HWIC switch cannot be configured as a network interface right? I'm pretty sure they can't as they aren't considered network interfaces but just thought I'd ask.

Cisco Firewall :: 1841 NAT Out One Interface But Not Other With IOS?

Feb 27, 2012

I am trying to figure out how to use a Cisco 1841 IOS router to take traffic from one interface and source NAT it out towards the Internet on one interface and at the same time NOT perform NAT when sending the traffic towards a different routed interface. 
 
Here the RemoteSite has connectivity back to the MainCampus, but there is no need to NAT traffic from the one site to the other.   They share the same umbrella of address space.   However, the RemoteSite needs to have its Internet-bound traffic NAT'ed out to the Public Internet via a third interface.  I know that I could just NAT everything out from the Remote Site and map the traffic back onto the same address space for intra-campus communication, but I'd rather avoid that and just NAT where I need to NAT it to the Internet.
 
I do have a caveat here:   in the event that either the MainCampus or the Public Internet interfaces go down, I would like to failover traffic from the downed link to other good link.  For example, I want to NAT all traffic (including "intra-campus" traffic) out via the Public Internet if the direct link to the MainCampus is down.  For the other example, if the Public Internet direct link is down, I would just send out all traffic without NAT towards the MainCampus.

Cisco WAN :: 1841 ISR Sub-interface With VLAN Tagged

Dec 7, 2010

I am trying to roll out a new internet router.  The problem I am faced with is the LEC only supports VLAN 1227 and greater, specifically they are assigning me VLAN 2528. I am able to create the sub-interface and setup dot1q encapsulation for VLAN 2528, but the vlan database does not have the ability to add VLAN 2528 to it so I am unable to get layer 2 up and going, thus preventing me from getting the implementation done.

Cisco WAN :: Input Errors On 1841 LAN Interface

Nov 4, 2011

I use an 1841 router as an internet facing firewall with a 10MB MetroE connection.  Lately users started reporting slow internet download speeds and web pages timing out.  Bandwidth reports do not show the link as being saturated so I looked at the interfaces on the 1841.   The interface connected to the provider shows OK as far as errors but the LAN side of the router shows steadily increasing input errors.  It doesn't show any other errors, no CRC, frame, runts, giants or overruns, just generic input errors.  What type of errors are those?  Nothing is being logged on the console.
 
I moved the connection to another switch ports and the errors continue.  I switched it down to 10MB and also changed the switch and the errors slow down but don't stop.  Interestingly, the switch side never shows any errors.  What can I do here?  I guess it can be a bad interface but that is such a rare thing that I am hesitant to replace the router.

Cisco WAN :: 1841 To Block Access To A Specific Interface

Feb 11, 2013

I have an 1841 between my firewall and the ISP.  Three interfaces - multilink to ISP, FA to my firewall, and FA to my inside network.  I use the inside interface for configs aand snmp access, etc.   Only my ISP-assigned fixed address block will get routed to the multilink by the ISP but I am nervous about the inside interface sitting on my LAN.   I know I can remove it, but if I keep it there, how can I set up an ACL so that all traffic from the multilink interface is denied to the inside interface?  I suppose another way to think about it that the inbound iface can only accept traffic from its own outside, not from the router.I think this is fairly simple but I don't want to knock down the traffic if I get it wrong.

Cisco WAN :: 1841 ADSL Interface Dropping Connection

Jul 2, 2012

We have an ADSL2+ line from a WIC in a 1841, everything has been fine for the last few years and then the last few months the connection going down. When checking the interfaces the ATM0/0/0 is up up and the same for the dialer interface we are using, they are both up/up, but this still needs a reload of the router to be functional again, shutting the interfaces does not bring the connection back up.
 
I am not an expert on ADSL lines, I have never really had a problem with anything previously. The router was running Netflow to a network monitor wondering if this or logging was causing an issue with entries in the buffer??
 
Here is an output of show dsl int, would change the firmware, it has been fine all this time before though we are running IOS 12.4(24)T1 advseck9-m, as far as I can seen from our ISP the config for ADSL is all correct. [Code]

Cisco Switching/Routing :: 1841 - Connecting Routers Via Serial Interface

Oct 22, 2012

While I managed to connect to each router individually, I decided it was time to connect the routers together via serial; as I don't have any serial cables and need to buy some, what serial cables I need, as well as to ask whether I have the right cards in my router(s) that will allow me to do so.
 
I bought 3 1841 routers, and all have a 1 port serial WAN Interface Card (WIC 1-T); one router has 2 of these, and one router has a WIC-1B-S/T .. My question is, can I connect the routers with a serial cable via WIC 1-T, or do I need a 2-T

Cannot Install The Drivers For TrendNet TEW-423PI Network Interface Card

Mar 20, 2012

I cannot install the drivers for my TrendNet TEW-423PI network interface card. I am running Windows 7 64-bit with an Intel i7 2700k and an Asus motherboard. I have tried installing with the card already in the computer - no luck. Card out of the computer install and then shut off and put in - no luck. The instructions that come with the card say that after you install the program that instantly runs from the CD provided you should shut off the computer and install the card and when you turn the computer back on the drivers will install automatically. It has failed to do so and although I pulled all possible drivers from TrendNet's site it still stubbornly refuses to even recognize that there are drivers for it to install.
