Windows 7: Cannot connect to internet

Cannot connect to internet

Recently I just installed the Win 7 32bit Home for my Coll at home, helped her with her Thomson Speed Touch modem which she never used before.

I connect the modem via LAN and it works flawlessly.

Until yesterday, she experience no connection from the internet at all. Window kept prompting that the TCP/IP is not found.
Light is still on for the modem but no connection.

Checked with ISP, and they assured that there's no problem at their end. What could be the reason to check?

Hi pboong,

- Check that you have the latest drivers for her network adapter. Get these from the manufacturers website not MS-update (to ensure that it's the latest).
- Ensure the IPaddress is dynamic (unless you need it static, if so let us know). Check all advanced properties of the network adapter to ensure that no static information remains. Also check that no proxy is used unless you know you are using one.
- Is the modem IPv6 compatible? If not you could try to disable IPv6
- From an elevated cmd prompt try an IPCONFIG /ALL and look for missign information, especially a missing default gateway. You may want to paste the results here. You can send the results direct to a text file like this.
IPCONFIG /ALL >> C:\mytestfile.txt

Let me know how you go and if you need further steps on anything, again let me know and I will break it down for you. Good Luck!

DSL Modems & Gateways - - Thomson ST536v6 (Internet zone)

This is the one.

I assured that the network adapter had been updated from Windows 7 when I first installed on the PC. Just happen that today her internet cannot be connected at all.

so on CMD, i will do IPCONFIG/ALL and look at the default gateway?

I told her to plug in her USB from the Modem to PC and it still does not get detected at all. I assume the device is out of order ;P

Hi guys,

It seem like changing the Lan Cable and modem router, the issue still occur. Guess that it might be network adapter is giving some problem.

What else can I do to help my friend now?

Told my friend to do a /ipconfig all and found out that only WIndows IP Config is shown and not Ethernet adapter Local Area Connection.

Does that means that her network adapter is giving any issue?

Windows IP Config is a standard heading, your adapters are found underneath. I've attached a screen print to help, your configuration my differ slightly.
The Pink section is the header. In my example, the yellow section is my wireless adapter, the blue section is my LAN adapter. The green area just shows some important things to check, i.e. check that the values next to them are not blank.

1. The modem itself should have a diagnostics page, where it will check and see why it has not connected. Find and run this.
2. Call your local ISP and ask them if they are receiving connection attempts from you. They can often tell you immediately what is wrong.

Thanks Tim Sitt.

However, according to my coll CMD. She only saw the top (your pink box) only. The blue box does not exit at all.
In device manager, Network Adapter did shown up. But there's just no IP found at all.

Contacted ISP as well and assured that the net is running well.

This is something she found:
There must be a problem with the driver for the Local Area Connections Adapter.
Windows couldn't automatically bind the IP protocol stack to the network adapter.

Will this help by resetting?

This is her Ethernet Adapter:
Atheros L1 Gigabit Ethernet 10/100/100Base-T Controller

Hi pboong,

If the LAN adapter doesn't exist at all, perhaps it is not installed or requires drivers.
Right click on the Computer icon (in the start menu)
Select MANAGE from the menu (computer management will open)
double click on device manager
Look for any devices with warning signs on them to show that the device has a problem
Look for any devices that are disabled (see pic)
Double click on the device for more information.

If this does't fix it, please screen print the device manager page and ask your friend to send us the ipconfig /all output. It is much easier to troubleshoot with this info.

The netsh reset may only help if the adapter is working.

PS: Have you seen any other Singaporeans here? I am moving to Singapore in March.

She did a search on Device Manager. No warning sign at all.

after doing the ipconfig/all, there no information apart from the Window IP.

Moving to Singapore? nice. I have no idea who is Singaporean here apart from me. HAHA. Welcome to Singapore. =)
