I can now connect to the internet and feel inept, as I did not realize what the problem was, and how simple it was to fix. Thank you very much for your help, Alain, this has been a learning experience, and I am all the more knowledgeable because of it.

Hi Alain, Sorry for the delay in between my responses. It is just hard to find time to wetup the router and troubleshoot it all the time! At the moment, I only have my laptop connected to the 871W, and I intend to connect through VLAN 1. As you can see in the Network Topology diagram that I threw together, there will be additional hosts, and a switch connected to the 871W, once the router is finally configured correctly. My laptop is currently connected via ethernet, but I have tested the wireless on the router by connecting via my wireless card. Of course, I still had no internet connectivity. Network Topology: Here is the ip nat translation output following a successful ping of 8.8.8.8: Here is the show ip interface brief: Here is the ipconfig from my laptop: Here is the arp -a from my laptop: Here is show adjadency FastEthernet 4(WAN port) from the 871W: Here is show hosts all from the 871W: I have not yet setup a type of routing for the 871W, so I would think that that would be the problem? At the moment, I reading about how to to setup static routing. Dynamic routing and default routing are next. However, I would just like to get this router up and running properly, so yhat I can practice commands, configuring ut, upgrading IOS's, etc, as I learn how to do those things. Let me know if any more information is needed. Thanks again for your help, Alain.

Thank you cadet alain. Could you explain what the purpose of these commands are, and what they do, exactly? I would appreciate it! Edit: I entered the commands that you specified, yet I am still unable to connect to the Internet, and am not sure what could be preventing this. Where should I be looking for the problem, and what information would be helpful to post to attempt to resolve this issue?

Okay, following the configuration of network address translation on my Cisco 871W, I am still unable to connect to the internet. Furthermore, I did not see any entries under "show ip nat translations" following the configuration of NAT. I was able to ping 8.8.8.8 from the router though. On top of this, I was also wondering how am to know what I should configure the DNS Server ip address to, or is this unnecessary on the router, as the cable modem takes care of it? Thank you all for sticking with me an helping me out!

Thank you to both of you, Giuseppe Larosa and cadet alain! NAT configuration was next on my list, but I thought that I would be able to access the internet before configuring it, so it appeared to me as if something else was wrong. Now, it makes complete sense that NAT is needed so the PC can access the internet under the "guise" of the router's IP address, per say. I do recall reading that loopback (127.0.0.1) was just for hosts, not Cisco devices. I've just been taking in so much inforation lately, that it is hard to retain it all! I will make the changes to my configuration that you have posted, Giuseppe. However, first I want to make sure that I understand all of them, instead of just typing them in and not understanding why my router is now functioning as intended. On top of this, I also need to find a window of time to commandeer the internet and properly configure my router! Thnaks again, and I will post back once I make these changes.

I am new to Cisco and am studying for my CCENT certification. At the moment, I am attempting to correctly configure a Cisco 871W lab router. Since I have undertaken this task, I have run into nothing but problems. First off it was finding that the previous owner had left a password on it, having to purchase a new USB to DB9 adapter to pass the "break" sequence to the router, and then resetting the router in ROM Monitor mode. Now, I cannot seem to configure the router correctly, and am quite stumped. My ISP is Charter (cable internet), and the home network that I am using consists of a Motorola SBV5122 Digital Voice Modem, Motorola SB6120 Cable modem, and, ideally, should also include my Cisco 871W router. When I connect my router to the SB6120 Cable modem, the router receives an IP address via DHCP and the WAN indicator light turns on. I have a VLAN configured on the 4 switchports of the router, and it is setep to act as a DHCP server. However, when I connect my PC to rhe router via Cat5e Crossover cable, I cannot access the internet. The router gives the PC an IP address, yet all attempts to ping the PC from the router fail. Somehow, I can connect to the router via SSH though. Furthermore, I can ping the 127.0.0.1 loopback address from my PC, but cannot do so from the router. All in all, I am very confused, and would appreciate any help/insight on my situation. All that I would like to do is learn how to correctly configure this router to function as intended in my network situation, however, this is proving to be seemingly unsurmountable! I have attached the config of my router along with both outputs and commands relating to my predicament.

Alright, the StarTech USB to DB9 Serial cable came today! I installed the drivers, connected it to the router, booted up, entered the break sequence, and was allowed into ROM Monitor mode. I then typed "reset", and all appears to be good! No I can get going with configuring this router! Thank you to all who helped, especially you, James.

Yes, sadly. I really do hope that a proper adapter allows me to enter the break sequence to access Rom Monitor mode. Otherwise, I will try to send the router back. Thanks again for your help, James.

Okay, I'm back, and I tried using Cisco as the password, as well as no password whatsoever. I forgot to order a proper USB 2.0 to DB9 console cable while at the hotel on Thursday night, but I did order one last night. In the end, I went with the StarTech one that I linked to previously. Here it is again: http://www.startech.com/Cards-Adapters/Serial-Cards-Adapters/1-Port-USB-to-Serial-RS232-Adapter-Cable-with-COM-Retention~ICUSB2321F

Alright, that's awesome, your suggestion worked, pompey! Now we may be able to get somewhere. I was able to enter the username of "cisco", as prompted, but when I entered the supposed password of "cisco", nothing occurred after 4-5 minutes of watching Tera Term. What's our next step?

Yes, my home network is setup with DHCP. In review it probably was the default gateway that I tried to Telnet to. How am I to Telnet to the router if I do not know its IP address? I will try SSH 1 and 2, and try to ping the IP once I am informed of how to find what it is. Sadly, I do not have access to a PC with a legacy Serial port. I am 18, and do not work a traditional job. I am merely trying to get my CCENT, and then my CCNA, as I am going for a degree in MIS, and would like to get into Netwrok Consulting.

I just tried to Telnet to the router via Tera Term, but the connection would just time out, and would not connect to the router.

I did try no flow control along with both hardware and Xon/Xoff. The results were the same. In leui of your suggestions, pompey, I am looking at getting this StarTech USB 2.0 to Serial adapter. http://www.startech.com/Cards-Adapters/Serial-Cards-Adapters/1-Port-USB-to-Serial-RS232-Adapter-Cable-with-COM-Retention~ICUSB2321F What are your thoughts on it, and is there a better version that you would go with, yourself? I will also try to Telnet to the router through my DHCP enabled desktop.

It is aid to support the Cisco break sequence. Any thoughts on it? http://www.amazon.com/Keyspan-USA-19HS-Hi-Speed-supports-Sequence/dp/B0000VYJRY Does anybody have recommendations on console cables for me, to ensure that I have a proper connection to my Cisco devices that supports all Cisco commands?
