As your article states, there is absolutely NOTHING that I can set on my modem. Success rate is 100 percent (5/5), round-trip min/avg/max = 36/36/37 ms Router4#undebug all All possible debugging has been turned off Router4#show log Syslog logging: enabled (0 messages dropped, 0 flushes, 0 Success rate is 0 percent (0/5) Let us have a closer look at what has happened: Router1#debug ip packet IP packet debugging is on Warning:Using the debug ip packet command on clear cdp counters Delete the Cisco Discovery Protocol table of information about neighbors.

This time, since the port is not valid, Router4 sends back to Router1 an ICMP message with type=3, a Destination Unreachable Message, and code=3 meaning port unreachable. At least I can stop scratching my head over this one.Thanks for the help @wilsontp and @thetechguru.

Don't be alarmed by the odd "Jan 01 1970" date-on most devices, the log function activates faster than the time-sync function, so the default hardware date is used during things like If you have a big house and have the router on one side, you might not be able to access the network from the other side of the house. He currently teaches networking, routing and security classes, while working in the field performing security audits and infrastructure design for medium to large companies.

If you look for a section with a label approximating "wireless security" you should find what you're looking for. But as a general rule, consider the following values when debating whether or not your physical lines and the connection to the provider are a problem. With Cisco Discovery Protocol, network management applications can learn the device type and the Simple Network Management Protocol (SNMP) agent address of neighboring devices. Ethernet Switch Contact Support NETGEAR Premium Support GearHead Support for Home Users GearHead Support is a technical support service for NETGEAR devices and all other connected devices in your home.

I think the assumption is that you have more wired devices than ports on your router's switch. Wired Router Note: The LEDs onNETGEAR routersdiffer depending on the model. It isn't just a weak signal that can cause a problem, but overly strong signals, too. http://www.howtogeek.com/99001/htg-explains-routers-and-switches/ You will use the show running-config command in the simulation labs.

Do not use unless told to do so by your service provider.

and of course, we all know that as olng as it is the same on both ends, it works fine.

July 25, 2014 Greg Hanson Good article and useful for http://www.cisco.com/E-Learning/bulk/public/tac/cim/cib/using_cisco_ios_software/07_basic_commands_tasks.htm You're basically looking for the word "wireless" and "setup" and/or "settings" in some combination. Modem Router Switch Diagram NAT is what translates the outside IP addresses to your local network so you can interact with people as far as the wide internet can take you. Network Switch Finally (and perhaps most importantly), knowing how to use the diagnostic page makes you an informed consumer.

This can be useful to have a rough idea of the delay on the link. Some old wireless devices won't support WPA, in which case you'll have use the less secure WEP instead. Understanding Home Networking Through Network Diagrams Rather than start off with a glossary of networking terms—and in the process slam you with a technical terms with no easy point of reference—let’s Sample output from the show version command follows: System Image Version and ROM Version This information indicates the running version of the Cisco IOS Software.

Other potential causes include noisy lines and incorrect data conversion. You can use port forwarding, however, to open up certain ports for certain machines on the network. Refer to Cisco Technical Tips Conventions for information on conventions used in this document. What Happens If My Smart Thermostat Stops Working?

i do have one issue with the article, and that is incorrect grammar. What Is A Router Success rate is 0 percent (0/5) This time, the source address is 20.0.0.1, and it is not working! No USB device is connected, or the Safely Remove Hardware button was pressed and you can remove the attached USB device.

Please use your shift key at least once per sentence.

Firewall: Routers act as basic firewalls in a variety of ways including automatically rejecting incoming data that is not part of an ongoing exchange between a computer within your network and Routers have 2 or 3 MAC's; they have a separate MAC for the LAN port, the WAN port, and the WiFi port. Sending 5, 100-byte ICMP Echos to 100.0.0.5, timeout is 2 seconds: Jan 20 17:04:05.167: IP: s=100.0.0.4 (local), d=100.0.0.5 (Ethernet0), len 100, sending Jan 20 17:04:05.171: IP: s=100.0.0.4 (local), d=100.0.0.5 (Ethernet0), len What Is A Modem For example, if one computer has a web server and another has an FTP server, you could open up ports for both of those services so people could access them from

At least I can stop scratching my head over this one.Thanks for the help @wilsontp and @thetechguru.

July 25, 2014 Keith Norton While describing switches the article states: "Unplug the devices M Could not fragment. ? The default value of this timeout is two seconds on Cisco routers. A powered-on device is connected to the Ethernet port.

Right now return time is 2 ms when pinging either the router or the modem, so there's currently no delay between them, and I can also verify the modem is responding. Trap Logging This field gives the minimum level of severity required for a log message to be sent to a syslog server.

If a bad connection, splitters on the coaxial lines, or even old television amplifiers are dropping the signal below or pushing the signal above the operating range, then you may experience Cisco Discovery Protocol can also be used to obtain the network address of the interface of an attached device. What to Look For Once you have access to the diagnostic panel, there are some basic things you want to look at: the modem status, signal strength, and the activity log. That is curious.

If you're going to correct an author , be sure to use that shift key to capitalize the beginnings of sentences, and spell your words correctly.

it is a common mistake, but one does not expect to find it being made by a writer, even a technical writer.
