Not Able to Connect to Internet.. Pls Help

Hi
I have just purchased a brand new HPdv5-1002AU notebook, but something weird is going on. I am not able to connect to Internet. I use a DSL connection with a modem provided by my ISP. When I connect the Ethernet cable to my notebook, there is no light on the NIC card as well as it shows that the network cable is unplugged. Also at the same time even my DSL modem doesnt show any LAN light. But if I will connect the same cable back to my desktop instead of Notebook, everything starts working fine.

So I was not sure whether the NIC card is bad or anything else, so I connected the same Ethernet cable between my Notebook and Desktop and they started working fine in networking.

I am a bit confused bcoz this shows that the NIC card is working and the modem and cable are also working.

I have tried to disable/enable network adapter, update the drivers after completely uninstalling the drivers. I have tried running Safe Mode with Networking, I have tried to stop the Firewall. I have contacted HP as well even they were a bit confused and told me to take the notebook to the service center.

I am stuck now and don't have perfect resolution for this. Any sort of help would be highly appreciated.

Thanx in Advance

 

I unfortunately don't have the answer.
But I had a similar problem and this just reminded me of it.
I had an hp zv5000 and a compaq presario sr1711nx.
When I hooked them up together with ethernet cables nothing would happen no light or anything. I fiddled with it for a whole day but never got any response.
Even though both of these computers would have a connection with other computers and networks they wouldn't connect to each other

I look forward to seeing an answer here

 

Open your network connections right click on your connection go to properties and make sure that you have just the Internet Protocol (TCP/IP) checked. Past that I am clueless.

 

Hi I have tried this as well but even this option doesn't work. Till now I have not been able to figure out the exact cause and the resolution.

 

With reading all that you've said you've done in ur original post I can't think of anything else you could do. If you have the latest drivers....;idk, sounds like the NIC is malfunctioning or something...might need replacing.

 

Check your event logs to see if there are any warnings or errors that were logged that relate to the wireless/wired cards.

 

Unplug your modem from your isp. turn off your laptop. Connect the cat5 cable.

Plug in the modem. Wait until all of your ready lights are lit and solid. Turn on your laptop. Surf.

 

If your desktop works and your NB does not when direct connect Your ISP is using MAC Filtering. What you will need is to setup a router and clone your desktop MAC address into the router. Then both pc's will work at the same time, and you will have wireless for your NB.

If you only going to use your new NB contact your ISP and have them reset the MAC address to your NB.

 

That is not necessarily true. It would certainly work to improve the ease of use of the situation, but it is just as likely the modem isn't forwarding dhcp requests once an address has already been assigned to a node.

Turning off the modem and restarting as I noted will check this. Mac filtering implies the ip address is assigned to only one mac address and others are blocked, but very few ISPs still do that as they got tired of people changing their machines out regularly. Often this means rebooting the modem solves the issue.

Now, whether he wants to mess with that all the time is another matter. In that case, a cheap router that handles DHCP requests locally with private ip addresses as you suggested is a far better solution

 

I have tried this as well. But even this doesn't work. Now even I think that might be ISP has binded my MAC of Desktop to the modem. I will call my ISP tomorrow because I think its not an issue with Notebook.

Also I noted that when I connect my NB directly to my desktop, I had to turn the firewall off. So I thought might be Symantec is the culprit. I downloaded the Nortan Removal Tool and removed Nortan completely from my NB, but the issue is still there.

Another thing which is really weird is that when I turn the NB on, the NIC card light comes up and stays on till the time Windows Logo doesnt come up. As soon as the Windows Logo comes up, the NIC card light turns.

Yes I am planning to buy a new Wireless router as well (might be next week) but untill then, I need some sort of Internet Connectivity on my NB. Internet is my lifeline.

Thanx and if anyone else has any sort of resolution for this... pls let me know... i really need someone's help.

Thanx to all who have replied back to this thread.

 

You know, I did not notice you were in India earlier. It is much more likely that they are mac filtering in other parts of the world then the U.S.

MAC addresses are burnt into your network device, however you can trick windows into using a different MAC address.

On good machine, START > RUN (or if VISTA, type it in search box above start orb)
type
CMD
<enter>

in the command line box, type
ipconfig /all
<enter>

Look for
Physical Address. . . . . . . . . : XX-XX-XX-XX-XX-XX

Write these numbers down.

Go to your laptop. Since it is new, I am assuming VISTA

START ORB, right click NETWORK, choose PROPERTIES, click MANAGE NEWORK CONNECTIONS

Right click your LOCAL AREA CONNECTION
Choose PROPERTIES

Click the CONFIGURE button

Go to the ADVANCED tab

In the PROPERTY box, scroll down to NETWORK ADDRESS and select it.

Click the RADIO button next to VALUE, and click in the box and type down the number you wrote down without the hypens, like
XXXXXXXXXXXX

Click OK and keep clicking the OKs until everything disappears. Turn off your computer. Hook it up to the cable/dsl modem and start your pc.

That work?

If it does,remember to undo the MAC address when your router arrives or your two computers will have a hard time communicationing on the network (the router won't know which computer to forward packets to)

 

This wouldn't cause a lack of the LAN light on the modem, or the connection "Local Area Network" being good in the laptop, but...

This is DSL right? What modem is that (make / model) ?

There is often the issue in DSL service as to wether you are using the modem/router from the ISP as a "bridge" or as a "router".

As a bridge - you would dial the DSL connection from Dial-Up Networking in Windows as a "PPPoe" (typically) type of connection - providing the username and password. The IP Address from the ISP would be held within Windows itself.

As a router - you would have configured the setup in the modem/router itself with your connection type and username/password. In which case the modem/router is always signed on. The IP Address from the ISP would be held within the modem/router

The modem/router runs DHCP SERVER built-in and should assign IP Addresses to any plugged in (you should be able to add a network switch-hub) computers or wireless (if it has it, or if you add a wireless AP.)

You may want to test your network cable to make sure it is REALLY good. Check that it has the same color scheme on both ends. Typically: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown. The so-called 568B wiring scheme. The opposite of that is 568A - where the orange ones become green.

If you have opposing schemes on the ends of the cable then it is a "cross-over" cable. The guy on here that couldn't connect 2 laptops should be using a cross-over cable. Most everyone else should not be.

If the laptop gets link lights (on the actual jack) and "UP" in Windows (even with "limited connectivity") from one networking device, then it should get the same from this DSL modem.

Let me know if this has been of any help. I'm subscribing to threads now, I just joined. But I certainly am no newby ;-)

 

Oh, good call we all missed. The modem being in bridge mode would certainly explain all of this.

 

* It's awful funny, see my other post as well, that connecting the notebook to the desktop by that cable that it networks fine. Usually that requires a cross-over cable. See my page:

/page-2.html#crossover on my web site (I'm not hard to find)

for why a workstation to a workstation should be a crossover cable.

But then again a lot of newer network jacks have auto MDI, MDI-X ports which auto-sense and switch to what they need to be electrically.

There are auto-negotiation protocols at work in ethernet ports to sense the capabilities of each partner. search for Ethernet in google and see the Wikipedia article. It's possible that for some reason that is failing. There used to be full and half-duplex auto-negotiation problems on some hardware, but it's rare these days. Sometimes you have to force the client to a certain setting to match the host or switch-hub/router.

 

Hi Thanx a lot guys for replying I will try all of these options

But today I I got the light on the NIC card by changing the Duplex settings from 100MBps Full Duplex to 10MBps Full Duplex... everything has started working but I am still confused why the NIC card and the modem have not been able to negotiate this automatically.

Now my desktop is still working on 100MBps Full Duplex but my Notebook is on 10MBps so i am a bit confused about this partiality by the modem

I think now it might be an issue with the drivers of the NIC card, so tomorrow I will connect to Internet and update the drivers asap and lets hope everything starts working fine.

I have contacted my ISP and they said that they have not binded any MAC address to the modem and they said that any computer should be able to use the connection.

I am sorry its a Router provided by my ISP. Earlier I had D-LINK router but that burnt out so this time they sent me a Chinese router which doesnt even mention the name of its manufacturer.... very strange. The only thing that is written on the modem is the model no: MT882. I have already told them to send me a D-LINK or a Netgear router. Also I am going to purchase a Wireless Router next weekend.

Please let me know the reason why I need to switch to 10MBPS rather than 100MBPS because this is the first time I have ever changed this setting on any computer.

 

I win again! I did say something about auto-negot. and duplex issues

I wonder if the modem is just 10MBPS Full Duplex capable, and the laptop is 100MBPS capable ... and just is not getting the message of that in auto-negotiation. A typical DSL modem LAN port (single port?) wouldn't need to be any faster than 10Mb/s because the Internet connection is never going to go that fast anyway.

What Duplex / Speed does something else get plugged into that modem?

 

Huawei Technologies SmartAX MT882 ADSL Router - this seems to be what you have. According to a manual that I found for it... it seems to have 10/100 Ethernet capabilities. The manual does mention the following...

2.3.4 Connecting Ethernet LAN to the MT882
MT882 may be connected to any 10/100Base-TX Ethernet port.
When connecting the MT882 to any Ethernet device that is capable
of operating at speeds higher than 10Mbps, be sure that the device
has auto-negotiation mode enabled for the connecting port.
Use a cross-over cable to connect the MT882 and the upstream
port of a switch or hub. Be sure that the cable connecting the LAN to
the MT882 does not exceed 100 meters.

* So again... double check that your network cable is good and not a cross-over. Also see if there is a way to check the status of auto-negotiation on the Ethernet Port on the laptop. (Note: I'm thinking that you've already done this... by the fact that you went and set it at 10mb/s Full Duplex.

(Don't feel sooo bad, I've had a server with a Intel ethernet card that's detected by my Dlink Switch as half-duplex 10mb/s... I messed around with it a bit awhile back, but then just pretty much left it that way. Other cards on other computers don't do that with my old Dlink 10/100 Switch.)

 

Anyway... since it only has 1 10/100 Ethernet port, why don't you get a wireless router or just a simple Ethernet Switch-hub and jack that into the MT882 and then jack the laptop into the Switch-hub? or even go wireless?

.....The nice thing about standards is that there are so many of them (and not everyone seems to follow them!)

 

That's gotta be one of the best lines I've heard in a long time!

 

Hi


Thanx a lot to all of you who replied to this thread.... this has even motivated me to add my replies to someone Else's thread so that I can help someone.

I finally got my Internet up and running on both Notebook and Desktop. But still couldn't really figure why it is not working on 100MBPS Full Duplex mode... but anyways at least its working.

Thanx once again

 

That's great. That's pretty much how we all started. Helping others is actually a great way to not only pay back for what you received, it is also a great learning tool. I have learned more about computers by reading about a problem and pondering how to solve it then I ever would have learned just waiting for only my own errors to show up

 

That's absolutely correct. If everyone in this world start resolving problems rather than creating new ones.... this world will be Heaven.
