Hi. I am using a Sony Vaio VGN-FZ455E laptop with Vista and a Linksys WRT310N router. However, when I try to connect wirelessly to the Internet, it only shows "Local Only" instead of Local and Internet. Last night, the connection was fine, but it will not connect anymore. Three other laptops in my household will not connect either, as well as my Xbox 360. I've also tried a wired connection to connect to my directly to my modem, but that does not work either. However, I can connct to other wireless connections in my neighborhood.

I try to diagnose the problem, but I get a message saying, "Cannot communicate with Primary DNS Server(68.105.28.11)." There is the option to reset the network adapter, but it says, "Windows tried a repair but a problem still exists. Cannot communicate with Primary DNS Server(68.105.28.11)." It just keeps going in a loop.

I did IPCONFIG/ALL and this is what I get:

so you have an ethernet cable pluged into port 1 and a PC - correct ?

I would suggest you turn off the wireless secruity - so that
Wi-Fi Protected Setup LED - On
IS this light Bl;ue or amber

Internet
A flashing LED indicates network activity over the Internet port.

What the make and model of the modem - any lights on here and whats there status

I would switch modem and router and PCs off

turn on the modem - let it settle
turn on the router - let it settle
turn on PCs

I've also tried a wired connection to connect to my directly to my modem,
this is a concern, however, do you have the drivers for the modem loaded ?

Log into the router and make a note of all your settings. log in and pasword etc

it may be worth reseting the router

Yes, that is correct. There is an ethernet cable plugged into a PC. However the PC has not been used since it is currently broken at the moment.

Currently, the Wi-Fi Protected LED setup color is blue.
However, I tried turning off wireless security for the router, but I couldn't connect to it anymore on the main laptop that I use. There was a message saying that there were conflicting security settings that did not match for my laptop and router, but once I turned on the security on another laptop, I could connect again.

The modem is a Motorola SB5101 SURFBoard Cable Modem. The lights are:
Power - On
Receive - On
Send - On
Online - On
PC/Activity - On (Orange and flashing)
Stanby - Off

I tried switching the router, modem, and pc's off and switchin them on again, but that didn't work.

So should I just reset my router?

Also, sorry, but I did not understand what you meant when you asked if I had the drivers for the modem loaded.

No, I have not yet called my ISP.

However, a wired connection to my modem now works, but the problem still persists with the router. I still cannot connect to my router.

I tried to diagnose the problem, but now I get a different message:
"Security settings on this computer might be blocking the connection.
The following policy might need to b e adjusted to allow Windows to connect.
Policy provider: Windows Firewall
Filter name: Query filter"

I then turned off Windows Firewall and tried to diagnose the problem again, but I get this message:
"There may be a problem with your Domain Name Server (DNS) configuration.
Windows failed to find the well known host "www.microsoft.com" using DNS. The server may be down."

The following procedure should get you a connection with any broadband modem that is configured to use DHCP for the router connection, such as cable modems, and many DSL modems. If you require PPPoE configuration for the DSL modem, that will have to be configured to match the ISP requirements.

Note that the wireless encryption and channel selection will have to be done after the basic wired connection is established, the first step is to get wired connections working.

  • 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 (COMMAND for W98/WME) to open a command prompt:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous command output!

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 206.190.60.37

PING yahoo.com

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

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

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.
