Hi. A lot of people have this problem - but I have noticed that the other threads all have some characteristic different than my problem, or they get too advanced and I don't understand, or frankly I just need someone to look at MY information and see if they can't help ME out.

When I try to connect through the ethernet cable to a router (model: Motorola SB512), I get "limited or no connectivity." It cannot repair the connection because it for whatever reason cannot renew the IP address. The computer is BRAND NEW and my old computer did fine, as does another computer, but my new computer (and my friend's computer) do this limited or no connectivity business.

Before we start making fun of the dumb girl, things I have tried:
1. Power cycling router/computer
2. Verifying that cable and ethernet work at other locations
3. Renewing IP Address (doesn't work)
4. Resetting winsock
5. Talking to Microsoft (completely not helpful)
6. Talking to Motorola (blaming Microsoft)

If someone could help me with this...I could not even begin to explain how much it would mean to me. I really appreciate any assistance.

its look like the network interface doesn't obtain an ip address from DHCP server, even it was enable on it (yes) on dos command.

the ip address also start from 169.254.*.*, can you please try to ping you loopback ipaddress 127.0.0.1 to make sure your NIC is working fine.If its replying, please disable and enable again NIC adapter in device manager.

good luck..

pls check ur ip and g/w...

Aha, so I am not familiar with how to do this or what all of it means (this is all new to me). Could you go into some more detail here?

 

[komakala]

The address 169.254.*.* is a private address that Windows uses when it is unable to find an address. A loopback address is an address that actually references your own network card. We can use this to verify that your network card is actually working correctly.

To ping your loopback address go to your command prompt (Start > Run > cmd > ok)

type in "ping 127.0.0.1" or "ping localhost" (that is your loopback address)

If you get a message stating Reply from 127.0.0.1 ..... then your loopback is working correctly. But if you get a message that says Address cannot be reached then it seems that there could be a problem with your network card.


To disable your network adapter get to your network connections screen
Start > Control Panel > Network Connections

Right click on your network adapter and click disable. Wait a few seconds after the icon turns gray then click Enable.

 

[johnwill]

Actually, the loopback won't test the output drivers of the NIC, which are the most failure-prone part of the card. The only way to be sure the NIC isn't bad is substitution of the NIC. Well, there is another way, connect the NIC to a known good router/switch/modem connection and see if it works there.

One point here. You say two computers have the same issue, which seems to point to a problem with the device you're connecting it to.

Are you SURE the cable is good? Can you connect ANY computer to that cable/router combination and get a good connection?

I will try the ping/etc when I get back home later. As for the cable, the cable works the same as my roommate's ethernet cable - as in, every computer that won't connect through my cable also doesn't connect through hers, and the same is true for computers that will connect. It does seem like there could be a problem with the router but I still don't understand why it works for some people and not others. Motorola was NO help - any of you guys have ideas on how to figure out if the router is the major problem?

I keep hearing about issues with this involving SP2. No one seems to have a solution, based on all the forums I've been on.

Based on the fact that it occurs on multiple computers, including a brand new one, I am sort of disinclined to think it's a problem with the network card, but I will definitely try testing that out later when I get home.

 

[Techie-Dude]

Just reading over what information that you have provided from within this thread, im more inclined to say its not a problem with your nic card or your cat5 cabling. Im thinking that there may be an issue with your router DHCP functions. Have you tried to set the IP statically to see if that maybe corrected the issue? This would also help us trouble shoot to see if it is the DHCP function failing on your router..

Ahahaha that is way over my head. Can you explain how I do that to the IP address?

I am a graphic designer but definitely not a techie.

Thanks, friend.

 

[Techie-Dude]

Absolutely ill be glad to help out Keep in mind everything that i post will be based off my configuration here at home and you will need to adjust yours ip addresses etc accordingly.

Lets start by right clicking on your network connection icon in your system tray and selecting the option "Open Network Connections". Once the Network Connections window pulls up we want to right click on your network connection and select properties. You will then get the "Local Area Connection Properties" window to display. Under "this connections uses the following items" we want to select "Internet Protocol (TCP/IP)" and then select the properties button located just below it.

Now. you should be within the Internet Protocol Properties menu. On this page you will see two options the first being "Obtain IP address Automatically" and the other being "Use The Following Address" We want to select use the following address. Now this is the fun part Your page should look simular to this:

IP Address: 192.168.1.102 (Just a demo ip that you can set depending on your router ip scheme)

Subnet Mask: 255.255.255.0 ( This should auto-populate for you, if it doesnt just go ahead and fill this info in.

Default Gateway: 192.168.1.1 ( This should be the ip of your router on your network, this of course varies depending on manufacturer of your router.

Ok now in order to get your DNS entries that will be needed for the DNS portion of the page you will more than likely need to contact your ISP. They will advise you on which dns servers to place in the listing.

Once you have entered all the information on this page dns ip address included go ahead and select OK on both dialogue pages. And then attempt to connect to the internet. I know im not the best "HowTO" writer in the world and if your a visual learner you may want to take a peak at http://www.hotcomm.com/FAQ/FAQ_staticIPXP.asp which has a visual diagram of what i described above.

Hope this helps you out with your issue

Reset the router to factory defaults by holding the reset button down for 15 seconds with power on.

• Turn off everything, the modem, router, computer.
• Connect the modem to the router's WAN/Internet port.
• Connect the computer to one of the router's LAN/Network ports.
• Turn on the modem, wait for a steady connect light.
• Turn on the router, wait for two minutes.
• Boot the computer.

When the computer is completely booted, let's see this.

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Ok - I did all that, using the numbers from my ISP and from the router manufacturer, and it stopped giving me "limited or no connectivity." Now it says, Local Area Connection Connected, Shared" and says it is connected but I am still not getting any internet. I did the whole power cycling/rebooting/reconnect/renew IP stuff. Here is this (I don't know if it will actually help, ha):

Let's turn DHCP on, don't know why it's disabled.

Select Start > Settings > Network Connections.

• Double-click the Connection icon of the connection you wish to modify to open the Local Area Connection Status window.
• Click the Properties button to open the Local Area Connection Properties window.
• Click to highlight Internet Protocol (TCP/IP).
• Click the Properties button to open the Internet Protocol (TCP/IP) Properties window.
• TCP/IP Properties window, IP Address tab
• Select Obtain an IP address automatically.
• Select Obtain DNS server address automatically.
• Click OK to return to the Local Area Connection Properties window.
• Click OK to return to the Network Connections window.

 

[mevandiver]

Ok, so when I have it set how TechieDude says, manually entering IP and DNS, it says that it is "connected, shared" but I still don't seem to be receiving a signal.

When I do it with the automatically selecting things (to enable DHCP) it goes back to Limited or No Connectivity. Either way, I don't get any internet.

The following is the IPCONFIG entry for this computer that DOES work using the LAN and the router.

[Techie-Dude]

Sorry for the late response, couldnt find this thread for the life of me, can you tell me when you do as i stated above by assigning the ip address automatically are you able to ping any ip or website? Enter the following command at command prompt for me

ping google.com

If you get a reply from googles servers this generall indicated a dns cache issue on this particular local machine, to clear your dns cache simply type the following command via command prompt as well.

ipconfig /flushdns

Once you have entered this command try to surf the net..

EDIT: Also make sure you have the following dns entries added when you set the ip statically:

68.105.29.11
68.105.28.12

No luck. I did all of the above, and it shows the connection as "connected, shared" now but still no browsing, and it could not ping google or an IP. Also, now DHCP is disabled...that seems to be the only difference between that computer and this one which works.

Argh!

 

[johnwill]

If DHCP doesn't work, configuring manually will probably not work either.

Of course, since you ignored my other suggestions, I'm not sure if I can be of any help here anyway.

Ha, I haven't been ignoring your suggestions, I promise. I did power cycle the way you said and it didn't help, and I have done it with DHCP enabled and with it manually configured. I am not sure what else do to :sigh: - the router works fine with many other computers and the computer works fine with all other routers and on wireless networks. So, naturally, all the manufacturers have nothing to offer.

 

[WarDwarf1980]

This might be worth a try. Get the connection back to where it says "connected , shared"

The go to control panel.
Go to administrative tools.
Go into services.
look for "IPSEC Services"
Double click it.
change startup type to disabled.
Click ok.
Close services screen.
Close control panel.

the try to ping www.google.com again.

Let us know if it says "destination host unavailable" or "unkown host" or what not.

If you cant ping it still then do everything again but change the startup type to "automatic"

Hope it works for you.

 

[WarDwarf1980]

You might need to restart as well...sorry. Forgot
