XP Pro won't receive from cable modem

[James156]

I built a new A7N8X PC, identical to my main PC. I am trying to set up a home network connected through a router to the internet via a cable modem. So the new PC is also connected to my cable modem service through a router, like my main PC is. It initially worked, (for the interntet only) then it stopped working, and my son tried the "repair" function unsuccessfully. I tried running the network wizard on both PCs in order to set them up as a local LAN communicating with each other, and to the internet via a hub (actually router). It didn't work. The new PC still can't receive any data from the internet, and "network places" (on either computer) does not show the other PC as being present. I ran the network setup wizard from the Windows XP setup /boot disk, BTW on both PCs.
I believe the reason that the new PC does not work on the internet is that when I click PROPERTIES/SUPPORT on the network connection icon, it says IP address is "automatic by private address". I think that if it showed "assigned by DHCP" it would work on the internet. And it is not on the same address as the main PC which works OK for the internet. The network name is the default MSHOME on both.
I can see from the router lights and the taskbar "popup" that I have a good ethernet conn. to the router from the new PC. It's the software setup that is wrong. I want to just delete the network connection on the new PC entirely and start over, but when I right-click on it, the option to delete it is grayed out! I cannot figure out how to change it to "assigned by DHCP" as the main PC is setup. Any help greatly appreciated.

Run the network setup wizard again, choose "other" - then "this computer is connected directly to the Internet".

what brand of router are u using?

[James156]

its a D-Link DI 704P Residential gateway. Like I said, initially we had an internet connection to the new PC THROUGH THE ROUTER. Then the network conn. was changed....not sure what he did, and then there was no working connection. But we tried bypassing the router....we plugged the cable modem directly into the new PC, and then it worked! (But of course then the main PC had no conn.) If we could just get both working again on thew internet through the router (and I have had two PCs running fine on the internet through this router at the same time before!), that would be fine...we could work on getting the local LAN going later on.

[James156]

I read somewhere that you cannot delete TCP/IP protocol. So I guess this is why DELETE cannot be selected on the right-click menu when I select the network connection icon? All you can do is change its properties or repair?

[kodmaster]

can you please ping 192.168.0.1

to ping you click on your start button|click run|type "ping *.*.*.*" replacing stars with the number and removing quotes

if that turns out to be successful go to internet explorer and type 192.168.0.1 type admin for username and whatever password you have set (default is blank) then click on wan and where it says primary and secondary dns input them from the information from your service provider. Next at the top click status and see if you have an ip address in the wan section if you get a whole bunch of zero's go to the sidebar and click log and copy and paste the log here and we'll go over that.

if not post back here with what happened.

[James156]

After resetting the router (DUH!), guess what....the new PC now is working on the internet. But now the main PC is NOT. The new PC has switched to ASSIGNED BY DHCP and has a adddress of 192.168.0.140. THe main PC which no longer works on the internet still has a good physical connection, but it does not receive any data now. So I pinged that computer, and a dos box opened up, and it pinged the address you gave three times successfully: "reply from 192.168.0.1 bytes=32 time =1ms TTL=64" I got the same results on the new PC also, BTW.
When I try to run the repair utility under network connections/SUPPORT, it always fails, it says it was unable to get new IP address.
I think that the 192.168.0.140 address is hard-coded into the router and that is its an unchanging physical address, is it not? So why can't the main PC pick up the correct router address now?

[glc]

192.168.0.1 is the IP address of the *router*. 192.168.0.140 is a good IP, that has been assigned to the PC by DHCP. What IP address does the main PC have now? DHCP should assign that too, between 192.168.0.2 and 192.168.0.254. Set the TCP/IP on the main computer to obtain everything automatically by DHCP and it should work.

On the main pc.

Go to your network connections and right click on your connection. Go to status and then click on the support tab under that tab it will have a box post what is beside each of the little things such as

ex. (these are mine)

Address type: Assigned by DHCP
IP Address: 192.168.2.101
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1

(i've got 2 instead of 0 because I had to change my router's address because of ICS)

If your thing doesn't have Assigned by DHCP as the first one right click on your connection go to properties. there is a list scroll down it until you get to TCPInternet protocol and highlight it and click properties make sure that the first circle and the third circle you see is filled in don't worry about making sure that the numbers are 0's.

This is probably confusing to you so i made a video that you can view at:

post back on how it went
I still got a few more ideas
or add me on msn at (pm me for e-mail(don't want to give it out to everyone)) and we can try remote assistance if you like

[James156]

The new PC, which IS working on the internet through the router shows this:

assigned by DHCP

192.168.0.140

255.255.255.0

192.168.0.140


The main pc, which still doesn't work though the router any more, shows this:

assigned by DHCP

24.155.24.173

255.255.252.0

24.155.27.254

The above settings for the main PC are what works when I have the main PC connected directly to the cable modem, not going through the router. Direct through the cable modem the internet works fine. SO it is just a matter of getting the conn. IP address changed to the same as the new PC, I believe. When I click "repair"...for some unstated reason it cannot repair the connection. (doesn't even say unable to obtain an IP address now). I just need to know how to manually change the connection to the correct numbers.
Then when they are both working through the router, I can tackle the next part of the problem, getting the two PCs to communicate with each other, because I am constantly having to transfer files by means of DVD-RW. Thanks!

Connect the main PC to the ROUTER and tell us what the IP's are, please.

[kodmaster]

OK... what does your connection say on your main PC when it is going through the router? I'm gonna assume you didn't tell me because you couldn't access it.

Disconnect the NEW PC from the router (I think it is acting as a DHCP server) but so is the router. So were going to disconnect it.

Put a paper clip in the back of the router where it says reset and hold it for one or 2 seconds (while the router is on).

Connect the main PC to the router and see if it will connect. IT should find that DHCP server because your other PC was acting as one. Which you don't want it to.

Next start-up the main PC still not connected to the router. Disable your network connection and connect the network cable to the new PC.

Do the second part of this tutoialI posted below (the second time it right clicks on the network connection)

That should fix that computer's Network Connection after you enable the connection again. If that doesn't work post back or PM me.

[James156]

Sorry perhaps I didn't make it clear...the settings shown for the main PC ARE what it shows when connected to the router. When I disconnect main PC from the router and connect straight to the cable modem so that I have a working internet connect, it shows the *same* thing. The IP address needs to be different when connected to the router, but it is not. I am guessing that is why it doesn't work through the router. Jim

[James156]

Will try your procedure soon, kodmaster, aand post reluts soon. Thanks.

[glc]

Is the cable modem plugged into the WAN/Internet port on the router, and are both PC's plugged into numbered switch ports? Have you tried another hard reset on the router?

[kodmaster]

Ok... What is happening is that yopu aren't turning off the computer after you restart the router second I want you to make sure that you automatically get an IP address from a server and that the router has DHCP server set-up. Second after this is done make sure that you turn off your main computer before connecting to the router. The router thinks that you are a WAN ip because that is currently what is assigned. Also I forgot to mention in my last post make sure you have any software that you have installed that acts as a server on both computers ex. FTP server, VNC, DNS, etc. Even downloading programs such as Bit comet and Lime wire. Oh and from my other previous post when It says the main PC still dis.......it shouold be new pc

[James156]

My son recently put Bitcomet on the main PC. Are you saying anything that acts as a server can keep it on a WAN IP address? I think they have multi-player games also installed that act as a server, as they can be the host for a game.

[glc]

Sounds to me like you need to do a hard reset on the router back to factory defaults and reconfigure it from scratch.

Step 1 Power the unit off by unplugging its power adapter.

Step 2 Insert a paper clip in to the reset pinhole. Press and hold the reset button with light pressure.



Step 3 Power the device back on by plugging it in. Continue to hold the reset button.

Step 4 Watch the lights on the front of the router. The M1 & M2 should come on solid. When the M1 & M2 begin to blink slowly, release the reset button.

The unit will reboot itself and should be at factory defaults. If the M1 light is not blinking about once per second, unplug the power on the router and plug it back in.

If the M1 & M2 continue to blink rapidly, you held the reset button for too long. Power the device off and repeat the reset procedure.

The default IP address is 192.168.0.1. The default username for our routers is admin. The password is blank. If your router asks only for a password, use admin (lower-case).

[kodmaster]

Bitcomet is causing it (it actually is happening 2 me 2) for some reason bitcomet can't work with a router. It's causing me to loose my dhcp on this computer that i'm on not mine. Tell him to uninstall it and shutdown everything and start stuff in this order:

Modem
Router
Main PC
New PC

I think that D-link for some reason removes DHCP if it's to much bandwidth (160kb/s on mine or more) I'm going to look into it and email d-link and if I get an answer i'll let u know till then try Azureus(it's not as pretty looking but It works,,, it think.

[kodmaster]

OK I think I fixed my router thingy... in the preferences | advanced |connection section you want to uncheck the first 4 boxes
also when you first start the preferences you want to change the port to a number between 50001-64999 and change it to that. make sure u remember the number. then go to your router config and forward that port on both tcp and udp

here's a tutorial for the settings that u should have
http://www.p2pforums.com/viewtopic.php?t=22421
and port forwarding
http://www.portforward.com/routers.htm here you would click on your router and on the bottom of your router will be your revision, then after u click on your router you will need to click on bitcomet

[kodmaster]

for some reason I can't edit my post so I have to tri post...weird. I was reviewing my answer becaue I was wondering if you replied and I seen that I didn't tell you that you have to uncheck the first.....that's in bitcomet no on the router. also you don't need to do the static ip like it shows you you can use your router to do it it is under the dhcp tab when you first enter your router config. Let me know how this gos
