Vista - Wireless connection works, cable connection does not!

05-15-2009

I am having the worst problems connecting using a cable connection, which I
need because as I am in Europe at the moment, many sites or private homes are
not equipped with wireless. Now, when I connect with cable, everything seems
to be working fine, the Toshiba connectivity doctor tells me I am connected,
the diagnose program assures me that the problem has been resolved etc. etc.
and yet whenever I try to connect (IE, Mozilla, Google, I have tried them
all), I get an error screen. I have tried everything I could think of,
checking my settings etc. Nothing works.
Let me emphasize that:
1) wireless connection works fine
2) it is a problem with my computer, not the host, since I have encountered
the same problem everywhere (libraries with password protected access,
private homes without password protected access etc.).
Can anyone help?

1. What does the error screen say? Please quote exactly without
paraphrasing.

2. Is the wired network adapter enabled? Look in Device Manager.

3. What antivirus/security program(s) do you have installed? I've seen cases
where McAfee (for instance) firewalls the wired and wireless connections
separately and you need to configure them accordingly.

4. The First Question Of Troubleshooting: If the problem is new, what
changed between the time things worked and the time they didn't?

Thanks for your response.

1. What does the error screen say? Please quote exactly without
paraphrasing.

I have been getting several, like "This computer has limited or no
connectivity.
Cannot communicate with primary DNS server (134.157.0.129)" or "Windows
failed to find the well-known host "www.microsoft.com" using DNS. The server
may be down."

2. Is the wired network adapter enabled? Look in Device Manager.

I did, thank you for the suggestion. Both the Atheros wireless adapter and
the Realtek RTL8101 are working properly. I noticed yellow exclamation marks
next to Microsoft 6to4 adapter and ISATAP adater no. 3. When I clicked on the
link I found a message indicating "This device is not working properly
because Windows cannot load the drivers required for this device. (Code 31)
Click 'Check for solutions' to send data about this device to Microsoft and
to see if there is a solution available." I did in both cases.

3. What antivirus/security program(s) do you have installed? I've seen cases
where McAfee (for instance) firewalls the wired and wireless connections
separately and you need to configure them accordingly.

I got rid of McAfee, which came with my Toshiba, about a year ago, having
noticed hat it kept causing freezes and other problems. Now I have Symantec,
to which I can connect (when I can connect) as a member of the Vassar College
community. I haven't noticed any particular problems.

4. The First Question Of Troubleshooting: If the problem is new, what
changed between the time things worked and the time they didn't?

This I can't answer because I cannot remember when or how the problem
started. As I said, generally I do not need a wired connection because in the
US most places are wireless now, but Europe is way behind and a wired
connection is needed in most places.

Thanks for continuing to advise if you can.

Hi Lyautey,

Open cmd prompt and type:
ipconfig /all

If everything is OK, you should get a valid IP address for your wired
network connection from a local DHCP service.

If DHCP service is not available, your IP address will look like:
169.254.y.z (where y and z = 1 - 254)
This range of addresses is known as APIPA and allows you to communicate only
on the local network, but not on the Internet.
If you get that address, you should ask the person who is in charge of that
wired network for help .

Another thing. When you use wired connection, make sure that wireless
connection is turned off.

Is that ip address assigned manually,or its getting from dhcp server? You can find this by typing ipconfig /all in command prompt.

disable the wireless adapter while connecting through wired. The gateway of your wireless adapter may interrupt your wired connection.

keep us informed

OK, it sounds like you are getting an IP address (or possibly not, I can't
tell unless you run ipconfig - see below) but you definitely have a problem
with DNS.

First do this:

Start Orb>Search box>type: cmd
When cmd appears in Results above, right-click and choose "run as
administrator". This will get you an elevated command prompt. At the
command prompt type:

ipconfig /all [enter]

See what IP address is assigned to the ethernet (wired) adapter. See what
DNS servers are listed. Post back with that information.

In the meantime: Is this computer a member of a domain? It sounds like you
have the wired adapter set to get DNS from 134.157.0.129. This was possibly
set up because of the college network. You need to set the wired adapter to
get its IP and DNS automatically. While you're at it, disable IPv6 too.
This Microsoft Knowledge Base article tells you how to do these things:

This is nothing to worry about and unconnected to your problem. Let's
address the IP/DNS issues.

Your computer is set to get an address from a DCHP server at 82.224.27.254.
A Whois lookup for that IP address produces this:

netnum: 82.224.26.0 - 82.224.27.255
netname: FR-PROXAD-ADSL
descr: Proxad / Free SAS
descr: Static pool (Freebox)
descr: menilmontant-5 (th2)
descr: NCC#2003105812
country: FR

(For more see: http://whois.domaintools.com/82.224.27.254)

So I assume since you said that you are in Europe that you are in France and
this is the ISP you're using. However, the DNS server is located at the
Universite Pierre et Marie Curie:

inetnum: 134.157.0.0 - 134.157.255.255
netname: FR-UPMC-NET
descr: Universite Pierre et Marie Curie
descr: Centre de Calcul Recherche
descr: 4 Place Jussieu, 75252 Paris CEDEX 05, France
country: FR

(For more see: http://whois.domaintools.com/134.157.0.129)

You are properly getting a public IP address from the ISP but failing on
DNS. Make sure your computer is set to get DNS automatically as described
in my last post to you (and disable IPv6 while you're there). Then flush
your DNS cache by:

Start Orb>Search box>type: cmd
When cmd appears in Results above, right-click it and choose "Run as
administrator". This will give you an elevated command prompt. At the
command prompt type:

ipconfig /flushdns [enter]

Exit the command prompt and try to connect to the Internet. Report back.

Lyautey n/a posts	Wireless connection works, cable connection does not! I am having the worst problems connecting using a cable connection, which I need because as I am in Europe at the moment, many sites or private homes are not equipped with wireless. Now, when I connect with cable, everything seems to be working fine, the Toshiba connectivity doctor tells me I am connected, the diagnose program assures me that the problem has been resolved etc. etc. and yet whenever I try to connect (IE, Mozilla, Google, I have tried them all), I get an error screen. I have tried everything I could think of, checking my settings etc. Nothing works. Let me emphasize that: 1) wireless connection works fine 2) it is a problem with my computer, not the host, since I have encountered the same problem everywhere (libraries with password protected access, private homes without password protected access etc.). Can anyone help?

Lyautey n/a posts	Re: Wireless connection works, cable connection does not! Thanks for your response. 1. What does the error screen say? Please quote exactly without paraphrasing. I have been getting several, like "This computer has limited or no connectivity. Cannot communicate with primary DNS server (134.157.0.129)" or "Windows failed to find the well-known host "www.microsoft.com" using DNS. The server may be down." 2. Is the wired network adapter enabled? Look in Device Manager. I did, thank you for the suggestion. Both the Atheros wireless adapter and the Realtek RTL8101 are working properly. I noticed yellow exclamation marks next to Microsoft 6to4 adapter and ISATAP adater no. 3. When I clicked on the link I found a message indicating "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available." I did in both cases. 3. What antivirus/security program(s) do you have installed? I've seen cases where McAfee (for instance) firewalls the wired and wireless connections separately and you need to configure them accordingly. I got rid of McAfee, which came with my Toshiba, about a year ago, having noticed hat it kept causing freezes and other problems. Now I have Symantec, to which I can connect (when I can connect) as a member of the Vassar College community. I haven't noticed any particular problems. 4. The First Question Of Troubleshooting: If the problem is new, what changed between the time things worked and the time they didn't? This I can't answer because I cannot remember when or how the problem started. As I said, generally I do not need a wired connection because in the US most places are wireless now, but Europe is way behind and a wired connection is needed in most places. Thanks for continuing to advise if you can.

Dusko Savatovic n/a posts	Re: Wireless connection works, cable connection does not! Hi Lyautey, Open cmd prompt and type: ipconfig /all If everything is OK, you should get a valid IP address for your wired network connection from a local DHCP service. If DHCP service is not available, your IP address will look like: 169.254.y.z (where y and z = 1 - 254) This range of addresses is known as APIPA and allows you to communicate only on the local network, but not on the Internet. If you get that address, you should ask the person who is in charge of that wired network for help . Another thing. When you use wired connection, make sure that wireless connection is turned off.

You can find this by typing ipconfig /all in command prompt. disable the wireless adapter while connecting through wired. The gateway of your wireless adapter may interrupt your wired connection. keep us informed

The > server may be down." OK, it sounds like you are getting an IP address (or possibly not, I can't tell unless you run ipconfig - see below) but you definitely have a problem with DNS. First do this: Start Orb>Search box>type: cmd When cmd appears in Results above, right-click and choose "run as administrator". This will get you an elevated command prompt. At the command prompt type: ipconfig /all [enter] See what IP address is assigned to the ethernet (wired) adapter. See what DNS servers are listed. Post back with that information. In the meantime: Is this computer a member of a domain? It sounds like you have the wired adapter set to get DNS from 134.157.0.129. This was possibly set up because of the college network. You need to set the wired adapter to get its IP and DNS automatically. While you're at it, disable IPv6 too. This Microsoft Knowledge Base article tells you how to do these things: http://windowshelp.microsoft.com/Win...b11e21033.mspx Quote: > I noticed yellow exclamation > marks next to Microsoft 6to4 adapter and ISATAP adater no. 3.
