| | 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? |

| | 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.

| | 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.

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.
