Cisco WAN :: 1941w AP Can't Ping 2nd Router / Host But Interface Reachable

Feb 2, 2013

From the router I can ping the 2nd router, all its host and all of the 1941w interfaces.
From the 1941w AP i cannot reach the 2nd router or any of its host, but I can reach the interface that is connected to the 2nd router but only one side of it.
Attached are both my router and ap configs. At the moment I am just trying to reach the 2nd router and its host so I can update the AP IOS image but cannot reach the tftp server.

Cisco WAN :: Devices Connected To 1941w Router Cannot Ping

Sep 18, 2011

I have a copper over ethernet connected to an adtran 908e connected to an ASA 5505 with a port connected to the router on the Gigabitethernet 0/0
I can ping to internal and external ip addresses but when a device is connected through the wireless signal then the device cannot ping anything; what could be stopping the device from pinging any ip addresses internal and external?
I posted my current config for the router and ap:

Cisco Wireless :: AP1262N Repeater SSH Web Configuration Interface Not Reachable After Alignment

Jan 14, 2013

we have a couple of AP1262N-E-K9 APs with firmware version 12.4(25d)JA1 operating in autonmous mode. One AP is setup as repeater while all others are in root mode.

The repeater has setup one parent MAC address so it associates every time to the same parent root AP. Given this setting, I am logging into the repeater via SSH and start the antenna-alignment scan: "dot11 dot11Radio 0 antenna-alignment timeout 4"
During this scan, the repeater disconnects from its parent to perform the scan so no output is visible at the SSH console. After the scan is finished, the repeater re-associates to its parent and some output appears on the SSH console.

8 of 10 times this procedure works fine: the scan is finished and I can continue entering commands on the SSH console. However, in some cases the repeater is not reachable any more for about 7 minutes. I.e. pings to the repeater's IP address are unsuccessful and the SSH connection hangs until it is automatically disconnected after a timeout. Also, the web configuration interface is not reachable. After about 7 minutes everything works fine.

Cisco Switching/Routing :: Can Ping From R1 To R3 SVI4 Gateway But Cannot Ping Host

Dec 12, 2011

I set this up and I can ping all the gateways but never the hosts.  I was hoping I could make these links between 6500's a mix of L2 and L3.  Check it out.  They are connected in a linear fashion R1--->R2--->R3.  I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4.  I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration.  I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface

Mar 31, 2012

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

Cisco WAN :: 2801 Ping To Router LAN Interface

Feb 7, 2012

I have one problem doing a ping to a router lan interface, I have 3 routers (2801) connected between each other (separated 1 mile each), the link is established trough microwave signals (connected to the 2801 fast ethernet interfaces), every router has a connection to a LAN. One of them is located at headquarters.Last thursday I replace one of the router with a cisco 2901, i configure the router with the same configuration that was on the 2801, i power up the router and the 2 link were up without problems.One day after the noc called me to tell me that after i replace the router they can't ping the router IP lan interface on the new 2901 (before the replacement the ping was sucessful). I called one user the lan connected to that 2901, and they can do a ping to the router's LAN IP address.

I can ping the 2901 IP wan interfaces, I can ping the LAN users ip address, but i cannot ping the router LAN IP address, from my desktop, and neither the 2 routers 2801 connected to the 2901.I show the configuration on the 2901, I couldn't change it because i didn't have time to do that, but i'll change the configuration to use ipsec tunnels.The configuration as you can see, has a crypto map, but the acl used by the crypto map, only permits the interfaces ip address, so i think that doesn't work, so the traffic doesn't get encrypted, but i don't know if that is the problem why i can't do a ping to the lan interface.

Can't Ping / Connect Ipv6 Host On Windows 7 Vs XP

What I think it involves is having ipv6 installed on each. I tried to duplicate the setup of both the XP and a W7 computer, installing the gogo6 tunnel. But apparently it's not setup on this computer because the ping result is the same as on the third computer which hasn't had ipv6 installed. s not setup on this computer because the ping result is the same as on the third computer which hasn

Ping Could Not Find Host / DNS And Key-port / Server Not Found

Apr 30, 2011

recently I had some malware on my Windows XP Professional (version 2002), so I followed a guide at Bleeping Computer [URL] to get rid of it. Problem is, for some reason, after I finished, I could no longer access the internet!When I try, FIrefox gives me their "could not connect" message: "Server not found. Firefox can't find the server at [site]." Check the address for typing errors such as instead of [URL]"When I try to log into MSN, the troubleshoot says I have a problem with my DNS and Key Ports.I'm not good with computers so I Google'd and found some ping-ing instructions. When I tried to ping [site], I get: "Ping request could not find host [site]. check the name and try again." This happens regardless of the site I use.Lastly, I tried "ping" from a troubleshooting site. It gives me: "Pinging with 32 bytes of data:
