Cable Internet Not Accessible through Router 7

[RexxSysProg]

I just put in cable Internet access. The installer hooked it up directly to the PC and it worked fine. Now I put a router in between the modem and the PC and the PC doesn't see the modem. If I disconnet it from the router and put it back directly into the PC the PC sees it. The PC does see a laptop that is also connected to the Router so I know the PC's access to the router is OK.

What am I doing wrong and/or what do I need to do to get it to be seen with the router? I am using Zone Alarm as a firewall but I want the router firewall too.

(Before I connected the router, I saw "Internet" in "Map Network Drive". But after I hooked up the Router it's now gone, even though I've disconnected the router. I don't know whether that is significant)

What make and model is your router?
How is the IP for your PC configured? Should be set for DHCP
Are you receiving an IP address from your router?
Is the router's WAN port connected to the modem?

Does the router have l.e.d.s which illuminate when devices are connected to it?
Does the relevant port light up when the cable modem is plugged in?
Some devices may require a crossover cable, i.e. between modem and router.

If the cable modem has DHCP enabled, i.e. it's allocating your PC an IP Address when plugged in directly, make sure the router (if applicable) isn't also trying to issue IPs.

Some cable providers will only let a single device (i.e. your PC) connect to their network and once that device's ID is registered they won't let you connect anything else. Others (like mine) allow any device, but every time you connect a new one you have to wait for up to an hour for their servers to authorise it.

I advise hooking up your router as you did before then waiting an hour or so to see whether it suddenly starts working.

If it doesn't, all is not lost because most routers allow you to change their ID to 'clone' your PC's ID. This ID is known as the MAC Address. Have a look in your router's manual or browse its config pages to see how to do this on your router. This page tells you more about MAC addresses and how to find your PC's MAC address, which you'd then enter into the router's 'clone address' page.

I would also mention that you should follow the directions included with your router. You also need to find the routers IP address and see if you can ping it from your pc.

I would also shut down Zone Alarm, as it may be blocking something that should not be blocked.

Who makes your router????? If you have a linksys router, there are tools you can download that will help you set up your router. They work fairly well anfd are FREE! Go to

http://www.linksys.com.

Then click on support. Then Technical Support and you should find the tools there.

Make sure you shut down all items in this order (PC then router then cable modem). Wait 10 minutes and start them in the reverse order (cable modem then router then PC) and see if that does the trick.

I've seen a lot of time that the cable modem won't give the router an IP address if you have just unplugged the modem from the PC.

Thank you all for your help and suggestions. This is a used router (Netgear) so I don't have a manual for it. I've tried turning off ZoneAlarm but it didn't make a difference. I will try both turning off the devices in the order suggested and turning them back on after 10 mins and connecting the router to the modem for an hour and seeing what happens.

The router shows the pc and laptop connection indicator illuminated but not the one for the modem. And yes, the modem has DHCP enabled.

I will try pinging the router again but as the PC can see the laptop through the router the PC is clearly getting out to it.

I will read the page recommended about the MAC adress because I am quite unsure of how to make changes to the router's MAC (will that affect the PC/laptop connection which is working?)

Again, thank you all for your help. I will try your suggestions and append here whether it is successful.

Would it help if I copied the results from ipconfig/all here with the modem connected directly to the PC and then when it is connected through the router?

 

[RexxSysProg]

One thing I wrote before was a mistake. When the modem is connected to the router the number for that connection is illuminated on the router - i.e. all three connections show they are connected on the router.

Router should display lights on (usually green) for connected, WLAN with the LAN light flickering showing activity. It should also display (usually orange) a light for each PC connected to the router in the LAN section. Try pinging 127.0.0.1 and post the results.

'Would it help if I copied the results from ipconfig/all here with the modem connected directly to the PC and then when it is connected through the router?" Yes

Go into Device Manager & see if there are any conflicts there. You may have to go to the maker of the router & download latest drivers for it. The ethernet cable may be bad or the router itself since it's a used one.

Hope this helps!

The router should be serving out DHCP, not the modem. And an ipconfig /all when connected to the router may help us to see if the router is indeed serving out addresses.

 

[RexxSysProg]

I tried shutting PC/Router/modem, leaving off for 15 mins and turning back on in reverse order. Did not help. Shutting down and coming up and leaving on for an hour also did not help. When I reconnected the modem directly to the PC I had to turn the modem off for a bit and turn it back on before the PC saw it.

I'll have to try to figure out how to get the IPCONFIG results here. I saved the results and COPY'd them but PASTE doesn't work here.

The lights on the router do indeed flicker for all three connections. No orange lights on this router.

I will try the ping and check the device manager tomorrow.

Thanks to all of you for your continuing help.

How do I get paste to work here so that I can paste the ipconfig o/p here?

 

[Freestone]

The model number of the router and cable modem make/model may be of use too.

Copy and paste of graphics doesn't work here, but paste of text does, at least for me.

 

[Nelviticus]

By default I don't think you can highlight & copy text from a DOS window with the mouse. If you can't, click the icon in the top left of the DOS window, select 'Properties' then tick 'QuickEdit Mode' and click OK. You should then be able to drag-select the text and hit 'enter' to copy it to the clipboard.

You can't copy paste from a command prompt, but you can redirect the output to a text file. Do this:

ipconfig /all >c:\ipconfig.txt

The resulting text file needs a bit of reformatting, but at least you can copy and paste.

 

[Nelviticus]

You can't copy paste from a command prompt

Yes you can, see the post above!

[SirBlack]

As Nelviticus said, yes you can copy & paste. Once you've highlited the text you want to copy, you can also click on CTRL C & paste it into Notepad or directly to your thread.

Only the green WAN light should flicker. The WLAN & Connected light should be a steady green. There should be an area displaying the ports available on your LAN. My router is a 4 port network switch so the front LED display panel shows under LAN 1 2 3 4. Whichever port you connected your ethernet cable to should display a steady orange light. The flickering green WAN light is simply demonstrating the activity going on.

XP and 2000 command prompt copy and paste is possible. Thank you, Nelviticus, for your method - that is a new one for me! Alternatively, though more tedious, click the icon in the top left of the DOS window, select Edit -> Mark, highlight desired text, then hit Enter or Edit -> Copy

 

[RexxSysProg]

The methods of copying the IPCONFIG results and putting them here are all good and work. Thank you - I learned a lot from that.

I was in the middle of posting the results here when a friend called. He dug up a copy of the manual for the used router I have. The manual says to use only one specific port for cable modems. I had moved the cable modem around to a couple of the ports but I must have not tried that particular one after the first couple of ports still failed.

So I connected it to that one port and it is working. I don't understand why that one port is unique or what is different about it. But that's what it said and now it does work.

I want to thank you all for jumping in and helping; thank you for your advice and suggestions. I am giving each of you a "Star Thank You" in appreciation. And I did learn things on the way from your advice so I gained from this. Thanks again for your help and your time.
