Cisco 2600 series router and cable modems

Hi everyone, I am just about to get started preparing for my CCNA... I am looking to pick up some used Cisco 2600 series routers to set up a home lab. I am wondering if it is possible to connect a cable modem directly to a 2600 series router? If so, do I need a certain type of WIC? I want to go from my cable modem, to a router, to my switch. Thanks in advance!

Hi,
Yes you can, using the Ethernet port on the cable modem, you can connect the cable modem to the router 2600, and the 2600 comes with builtin ethernet or fastethernet (according to your platform).

Hook together chromebook,printer,router and cable modem

how do i hook up with cables to just the charter internet,and hp 3052a printer using a belkin 750 router and using hp chromebook 14 to type messages with?need to know what cables to hookup to printer,router and charter modem to get them all in sync.

Hello bozza,
Welcome to the HP Support forums. I understand that you would like to learn how to setup your Deskjet 3052A printer so you can print from your Chromebook.
The cables we need before starting is to have everything powered on. You also need to have an ethernet cable running from your modem to your router. And that will be all the cables we need.
Your Chromebook requires any printer to be set up with HP ‘s ePrint feature or Google Cloud print. Your Deskjet can do both but we first need to connect the printer to your wireless network. I have included a link to a post by Jon-W that has the steps on how to do this. Please start where he says “There is another alternative …”
Now that the printer is connected to your wireless network, let’s get the printer’s ePrint feature set up. Please follow the steps in Getting the Printer Claim Code. Once you have your web services information sheet please follow the instructions on Setting Up a Custom Email Address for ePrint.
Now that the printer has a customized ePrint email address please follow the steps in Using Google Cloud Print with your HP Printer to get the printer set up with Google Cloud Print. I have also included the Print a Page document from Google for additional reference.
You should be able to print from your Chromebook to your Deskjet 3052A printer.

Configuring Solaris 8 Sparc w/router and cable modem

I recently purchased a Sun Ultra 10 with Solaris 7
pre-installed. I decided to immediately upgrade to
Solaris 8. The operating system has installed properly
so far.
However, I'm at the point now where I am entering
information to allow Solaris to connect to my network
and thus the Internet, and the combinations I have tried
don't work.
I use a cable modem service with a Netgear RT314
four-port router. It functions in a standard way - the
cable modem is 192.168.0.1 and shows up on my
WinXP PC (in ipconfig /all) as the DNS server and
gateway server. On the PC, for "Connection-specific
DNS suffix", I see nc.rr.com (my ISP).
Solaris 8 wants to know my domain name, as well as
my DNS server. I don't know what domain name to give
it. I have tried nc.rr.com, but when I enter that plus
192.168.0.1 as the DNS server, I end up receiving this
message: ""Unable to find an entry for dchppc3 with the
specified DNS configuration."
I have been afraid to move beyond this point, although
it's possible that it will work properly and just isn't
receiving the confirmation it expects.
Any suggestions would be welcome, either in this forum
or emailed to me. My address is [email protected]
Thanks.

I decided to plow ahead with the installation. It works
properly within my local network - I can ping dchp
addresses and view Web files from my local server
using 192.168.0.3 (that machine's dchp address).
However, it can't get to the Internet. So my problem
now is that I can see the router, but can't see the
Internet services that the router provides to the other
computers on my network. Presumably, I need to
alter my DNS settings ... however, on my PCs, I seem
to simply use the router (192.168.0.1) as the DNS, and
it properly passes the request along to my cable modem
provider. Why would this work for the PCs but not for
Solaris 8? Thanks -

Accessing home mac fromwork through a router and cable modem

Hi - i'm really struggling with this - spent hours looking around net finding out how to set this up and as far as i can tell i've got it all set right - however it refuses to work.
I want to be able to access files on my home mac from work. Various ways of doing this i have read is SSH (or SFTP - Remote login) FTP Access or personal file sharing - tried them all can't get any to work so problem somewhere.
Have an NTL cable modem wired to a Netgear RP614 router which has Ip address A.A.A.A on its WAN port. It has B.B.B.1 on its LAN port. I have an airport base station acting only as a wireless access point (ie DHCP is turned off) router is allocating IP addresses - my ibook has B.B.B.3 - but have reserved this address for my iBook, ie it is as good as fixed as the router always gives my iBook this IP (using MAC address). Have port forwarded all necessary ports on the router, 22, 20, 21, 548 to B.B.B.3. Apple firewall is switched off - what am i doing wrong? I have also set the router to link to a DynDNS service to update its WAN IP everytime to my domain name i have set up.
If i try to FTP with transmit or fetch it doesnt work, if i try SFTP with fetch or transmit it doesn't work, and filesharing via connect to server doesn't work.
What am i dong wrong? How come everyone else can get this working but i can't?
cheers!!!

Right i tried my iBook connected directly to the cable modem and everything works then! Although one thing i did notice is that in the sharing windows in preferences at the bottom where it tells you how to connect to that particular service it didn't report the Ip address it reported a name - something like bcu-cu-cust36-bag-ntl.com - however when i looked this up it did resolve as the IP address reported by my network preferences.
So i'm not quite sure whats going wrong here - i'm gogin to try taking my airport base station out of the equation and hard wire my laptop to the router and see what joy there....

How to bridge a linksys cisco E1200 series router?

I have recently purchased a linksys cisco E1200 series router and would like to know how to bridge the connection to my xbox

The connection between your access point, router, or cable modem and the Internet is broken.

At random points throughout my laptop usage, I randomly disconnect from the internet and receive these 2 messages:
1. The connection between your access point, router, or cable modem and the Internet is broken.
2. The default gateway is not available.
It fixes the issue for a short period of time, but constantly happens. This is really starting to annoy me. I have no problems on any other internet, and other people i live with are connected with no issues to the internet. I have tried a number of solutions
online that has "worked" for others to no success such as resetting the router, fooling around with command prompt, and changing the performance settings to not drop internet when low on power. Does anyone have a solution for my technical problems?
I am running Windows 8.1 on a Lenovo ideapad that is less than a year old. I will be honest I am not a very knowledgeable person when it comes to computers, so please use simplified explanations.

Setup 1941 router with cable modem and 2 vlan?

hello everyone,
i need a little help setting up my new 1941 router with cable modem using 2 vlns.
this is what i have:
1- 1941 router configured as g0/0 wan port facing isp configured as (dhcp). g0/1 is lan facing the switch (192.168.1.1)
dhcp pool (192.168.1.x)
2- sg300-28pp switch.
3- wap371 AP/ 11pcs..
now everything is working perfect except sometimes we have more than 250 to 300 people trying to connect to the wifi, the router will have no enough ip addresses.
i heard that i can setup 2 vlans to solve this problem? and is there any setup that i have to do on switch and Access points?
please i will appreciate any little help
Regards

hello Andre Neethling i added network 192.168.0.0 255.255.254.0 to dhcp pool config and it seems that it is working but i am concern that i am going to have problem in the future so please take a look at the running config and let me know if i have everything done right. also we want to order static ip address from the provider for our security camera system and we will not longer receive dhcp ip from them and my router setup is to receive it as dhcp on g0/0 so what i should do about changing the settings on g0/0?
i appreciate your help

Question about setting up rdp using a cisco 800 series router

HI there,
I am currently in school for networking. One co-op placement I went too handed me a cisco 800 series router to practice my routing skills on. I am trying to setup RDP so I can access my server from outside my internal network. I ran this following acl command to do it.
ip nat inside source static tcp server IP address port# cable modem IP port # extendable.
My question here is, my cable modem will occasionally hand out a different IP since it has DCHP. I cannot turn DHCP off in my cable modem. So is there a way I can set this up to use a dynamic IP from my modem so I alwasy have access to it or every time my modem changes the IP address do I have to go in and modify this acl?

Configure DDNS ( Dynamic DNS ) on the router. For this you need to register with a DDNS provider. Go to
http://www.no-ip.com/ . they provide free reliable service.
With DDNS, Once your router gets a DHCP address from your ISP , it will dynamically update the DNS name record. For example if you register you routers name as, "myrouter.no-ip.org", from there onwards whatever the IP your router gets, you can refer to that by this name.
So do as what Paolo said regarding using interface instead of ip, and register with the DDNS and you are good to go..
Hope this helps

What I notice in the original post is this error
ARP: address resolution for 10.0.0.2 timed out.
which says that the router is looking for the 10.0.0.2 server but not getting response to its arp request. Can the original poster clarify for us how the device that has the image file is connected to the router that has the problem? Also what kind of device is 10.0.0.2? Is it a PC running TFTP server software or is it something else?

Upgraded to Maverick. Now cannot connect to wifi. All my other devices will connect. Have rest wireless hot spot switch and cable modem. Other devices still connect but MacPro does not. MacPro wireless is self assigning an IP address blocking access.

Upgraded to Maverick. Now cannot connect to wifi. All my other devices will connect. Have rest wireless hot spot switch and cable modem. Other devices still connect but MacPro does not. MacPro wireless is self assigning an IP address blocking access. It will connect if I connect to my iPhone hot spot via wifi. Any ideas?

If you follow this video you'll see how to delete your WiFi AP from the OS, this will allow you to select it again which I feel will correct your problem.
