Toshiba laptop to airport extreme cannot get connection

First time you should connect an Ethernet cable to the AirPort, and set it up with the software it came with. Then take a note of the wireless network's name (SSID) and the password (you might want to chance them to your personal preference though), security youre using (WEP, WPA, or WPA2)

You need to perform a soft reset of your router. There directions to do this from the Apple web site are:

1. Connect the AirPort Base Station or Time Capsule to power.
2. Press and hold the reset button with a pen or pencil for 1 full second, then release it. The light (LED) will begin flashing amber, indicating that the AirPort Base Station or Time Capsule is in soft reset mode.
3. From the AirPort menu bar item, choose the network created by the AirPort Base Station or Time Capsule (the network name does not change).
4. Open AirPort Utility in Applications > Utilities on a Mac using Mac OS X, and in Start > All Programs > AirPort on a computer using Windows.
5. Select the AirPort Base Station or Time Capsule and click Continue.
6. A window indicating that the device has been reset will appear.
7. Select "Restore the previous settings" and select OK.
8. Move through subsequent windows to make changes to your passwords or other settings as desired, clicking Continue after each one.
9. When you have moved through all of the selection windows you will be able to select Update. Click Update to install the new settings.
10. Click Continue to allow your AirPort Base Station or Time Capsule to restart.
11. Quit AirPort Utility.

If your network is being created by an Apple AirPort base station, use AirPort Utility to put the base station into "manual setup" mode, then pull down the "Base Station" menu and select "Equivalent Network Password". Try the value shown there.

Basically Time capsule is same as Airport extreme base station added with a hard drive to take wireless backup.Put same Network Name and password in both Time capsule and airport base station.Suppose your are making TC as a primary base station and Airport extreme as a secondary base station. Select WDS in both the base stations .In "Wireless Mode" select"Participate in WDS network" in both the base stations.Dont change rest of the options.Put TC Mac id to Extreme base station and extreme Mac ID to TC.now open the airport option in your laptop and check.you can see a single network name.Its DONE.Njoy using wireless

ip settings,, may be ur getting a bad ip or ur dhcp is not configured properly... reset tha router and reconfigure it

connect the airport extreme to the voyager using a network cable... factory reset the extreme and then connect to it using the airport utility... you should get a setup screen where you can switch the extreme to "bridge mode" .. everything else should happen automatically.. you will then have 2 wireless networks?

This depends... Reaching them wirelessly may be unreliable for a number of reasons, so, I'll proceed on the assumption that you are attempting to test in the simplest lowest-variable situation:
First, make sure that you have the latest Airport Utility for your Mac.
Connect your Mac to the Airport via a single Category 5 (or 5e or 6) cable. Factory-reset the Airpot and then wake up the Mac. If the utility still can't discover your airport, it's probably time for a trip to your local Genius bar as you most likely have a hardware problem.
Lather, rinse, repeat for each of the two airports.

Hi,
OK, do you have the latest version of Apple's Airport Utility: Version 5.4.1 (541.9) ?
If you don't, get it... it's got an excellent interface that will walk you through bridging two wireless routers together.
Once you get your hands on it, you will need to choose which airport will be the primary and which will be the secondary. Ideally, pick the one connected to the highest speed and most reliable internet access.
Connect to the secondary airport and configure it as bridge to the primary, the Airport Utility will walk you through it step by step.

Open up your airport utility software.
Connect to the base station.
Under the main menus look for network equivalent password.
