No connectivity, sending packets but not receiving them

Do you have a third party firewall?  It could be clocking your DHCP requests.  Try turning off the firewall until it finishes booting.  See if that helps.  Also sometimes it helps to disconnect from the router, unplug the router from the wall power, count to 10 then plug it back up, wait 30 seconds then connect the PC.

 

Start, Run, cmd.exe, OK to bring up a black cmd screen.  Type with an Enter after each line:

 

ipconfig /all

 

(Examine the output for the IP address and mask that it is using on the network connection that you use to get to the Internet.  You may have one for the wired RJ45 connection and one for wireless.  If you are talking to the usual small router it will have assigned you an IP address that starts with 192.168.x.y.  Usually the mask will be 255.255.255.0 and the Default Gateway and DNS will be that of the router usually 192.168.x.1 (x is usually 0 or 1 depending on the router maker).  If you see 169.x.y.z as your address then DHCP has failed and Windows has made up an address for you.)

 

(If you see 169.x.y.z then try the following: )

 

ipconfig /release

ipconfig /renew

ipconfig /all

 

(If DHCP is not working it will tell you and then assign you a 169 address again.  IF it is working this may fix the problem.)

 

(I also see a lot of problems with the DNS not working on the routers.  To check the DNS: )

 

nslookup dell.com

 

(Do you get an answer of:

Name:    dell.com
Addresses:  143.166.83.38, 143.166.224.244

or does it time out?)

 

(If it times out then close the cmd window and do the following)

 

Close all programs.  Click Start, open the Control Panel. If it says "Pick a category" up the top, click the "Switch to Classic view" link in the top-left of the window. Click Network Connections.
Right-click on the icon that represents how you connect to the Internet and select Properties. On the General tab, click the Internet Protocol (TCP/IP) component (you'll find it in the list in the top half of the window) and click the Properties button.

On the new window that opens,  in the bottom half of this window, select the Use the following DNS server addresses: option, then enter the  DNS resolver servers in to the boxes below:

Preferred DNS Server: 143.166.83.13

Alternate DNS Server: 143.166.224.3

Click OK.

 

Try it now.

Hi Ron,

Thanks for the advice. 

3rd party firewall?  Sorry, I dont know.  Im just in my home, cable out of the wall into the router, from there one into the Panasonic that inet works on, and one cable to my eternally fitful Dell that the net wont work on.

 

Here is what it gives me each time Ive ipcong/all 'd. 

Host Name . . . . . . . . . . . . : DELL

       Primary Dns Suffix  . . . . . . . :

       Node Type . . . . . . . . . . . . : Unknown

       IP Routing Enabled. . . . . . . . : Yes

       WINS Proxy Enabled. . . . . . . . : Yes

 

thernet adapter Local Area Connection:

 

       Connection-specific DNS Suffix  . :

       Description . . . . . . . . . . . : Broadcom 440x 10/100 Integrated Con

oller

       Physical Address. . . . . . . . . : 00-11-43-60-EF-4C

       Dhcp Enabled. . . . . . . . . . . : Yes

       Autoconfiguration Enabled . . . . : Yes

       Autoconfiguration IP Address. . . : 169.254.180.142

       Subnet Mask . . . . . . . . . . . : 255.255.0.0

       Default Gateway . . . . . . . . . :

 

So since it gave me 169.x.y.z, I followed along;

ipconfig/release

ipconfig/renew (which it couldnt complete)

ipconfigall (turned out same numbers as above)

 

Proceed to nslookup dell.com 

Is this a command prompt?  I tried but nothing came out, could not connect. 

 

I then went to the last paragraph you wrote; I typed in the DNS numbers your provided.  Unfortunately it didnt help.  Was I to keep "obtain IP address automatically" checked? 

 

Thanks, hope theres a Plan B somewhere.

169 means DHCP is not working.  Plan B is to manually assign the IP address, mask, and gateway.

 

Unfortunately I don't know what kind of router you are using.  You can usually manually assign 192.168.x.10, Mask: 255.255.255.0, Default Gateway: 192.168.x.1  where x is either 0 or 1 and it will work with most routers.  IF you check with your router it should tell you what IP address it uses or you can just try each and see if one will let you ping the gateway.

 

From a cmd prompt:

 

ping 192.168.0.1

(or if you set x to 1 then)

ping 192.168.1.1

 

If you get replies then you have assigned the correct ip address.  You can leave the DNS set to the Dell DNS.

 

A third party firewall would be something like Zone Alarm, Comodo, or one of the Antiviruses that include a firewall.

 

What is the Panasonic that inet works on and what is inet?  If the Panasonic is a PC then ask it what IP address it is using and that should tell you what x is and you can also doublecheck that the gateway is what I think it is. 

 

Which router do you have?

 

Ron

My router info, describing it as best that I can.

CentreCOM FS708XL  10BASE-T/100BASE TX

Fast Ethernet Switch

 

In the PORTS/LED Mode area;

Auto Nego - Set to ON

The toggle switch between 100M and FDX is set to 100M

Speed is set to Duplex.  All 8 ports set at 100M

The main port (8) has the cable from my modem. (lit up)

Port 1 goes to the Panasonic Computer.  Its lights are lit up.

Port 3 goes to the Dell Computer.  Its lights are lit up.

 

I ipconfig/all'd to the Panasonic Laptop that the internet works on. 

IP Routing Enabled NO

WINS Proxy Enabled NO

Ethernet Local Area - Intel 8255x-based PCI Ethernet Adapter 10/100

DHCP Enabled YES

Autoconfiguration Enabled YES

IP 219.168.46.13

Subnet Mask 255.255.254.0

Def Gateway  219.168.47.254

DHCP Server 219.168.47.251

DNS Server 218.176.253.65

                    218.176.253.97

Look at this post and see if it helps.

OK.  I see the problem.  You don't really have a router.  It's just a switch that I suppose is just connected to a dsl or cable modem (unless it's also a modem too.  Hard to find anything on it but the address the good PC is showing is a valid IP address so their definitely no router.).  To run two PCs off a cable or dsl connection at the same time you need a real router.  Linksys or netgear or even ehome.  The cable/dsl modem only has one IP address to give out and the first PC that asks will get it and the next one will get nothing.

 

To make your sick PC work, disconnect the working one, then make sure your sick PC is set to obtain the IP and DNS addresses automatically then disconnect from the switch. Now turn off power on the cable or dsl modem.  Count to 10 and turn it back on.  Wait a minute for it to boot back up then plug in the sick PC to the switch.

 

Run the ipconfig /all command and see if it got an address like the good PC had this time.

PS--> without powering down/up the modem, I can take out and replug in the Panasonic and it will connect to the internet (that is how I can get on this site).

 

I put my Internet Setup CD (YahooBB) into the Dell PC, when it said 'limited or no ....".  I tried to set it up with 'easy setup', it got an IP sent back OK with a Ping test saying 169.254.180.142.  But the DNS Test said Address Error!  a couple of times.

 

How can I make my Dell get this DNS properly ?  Im ready to A) reinstall windows XP and hope something helps or B) trade the PC for a pack of baseball cards.

 

Thoughts?

Thanks.

If thats the case, then Ill just as soon abaondon the panasonic as I *need* the Dell (sick pc) to work. 

 

I unplugged from the Panasonic.  Turned off the modem, waited, plugged into the Sick PC and turned on.  It tried to aquire the IP yet again, and came back with the same answer, 'limited or no connectivity'. 

 

I have it set to obtain both IP and DNS automatically..  now its down to no router, just a straight cable coming out of the modem and into my Dell.  How can I make this connect to the Net??

You can try setting the IP address/mask/defaultgateway/dns address manually to be the same as the Panasonic.  Then cycle power on the modem (also press the reset button on the modem if it has one).  See if that works (with the panasonic not connected). 

 

If that doesn't work it may be that the ISP needs to reset the MAC address for your installation on their router and you would have to talk to them.  Sometimes the MAC address will time out after about 4 hours so leaving the Panasonic disconnected over night may allow the sick PC to work.

 

One last thing to try is to run winsockxpfix.exe from:

This should correct any problems with the tcp stack.

UPDATE:  I called Dell in Canada, from Asia at LD rates, but it had to get fixed (I had tried your suggestions and thank you for them).  What ended up working was going into device manager, and uninstalling the Broadcom.  Then proceeded to restart, let windows detect and reinstall the Broadcom controller, and then plugging the LAN cable back in...  the first time it was set to "obtain" etc automatically, and it worked!

 

But I cannot just move the cable from laptop to laptop and connect each.  I have to unplug, wait, power down the modem, fire it back up, wait, then plug the cable into the desired laptop and cross my fingers.  The dell has been finicky still, and Ive reinstalled the Broadcom 5 times so far.  The last time I had to manually input the IP and DNS from what I had read earlier and it worked. 

I had this same thing happen trying to communicate with a Dell Desktop through a Netlink wireless router.  I was also using Belkin wireless network card.  Thru alot of experimentation, the same this would happen using a network cable with the internal network card between the computer and router.  I used a different computer and the wireless connection worked.  Could there be a loose connection or defective hardware component in the Dell workstation?

 

Thanks for the help.
