Reply: What wireless card does your macbook have?

REINSTALL THE DRIVERS AND SOFTWARE FOR DLINK. TRY A DIFFERENT TYPE OF USB WLAN.

Thank you for contacting Fixya Support, I am glad to assist.

Depending on what type of Internet service you are using, your Intel iMac comes standard with an Airport Extreme wireless card built in. As a result, if you are unable to connect wirelessly to the Internet, you will need to try this:

- Click on the Apple menu icon, located in the upper left corner of your screen and select System Preferences from the drop down menu.

- Now locate Network from within System Preferences.
- In the side window, make sure you see Airport and check also to see that it is turned on. If it is, then check the left side window to see if the AirPort connection is active.

Keep in mind, your modem or connection router of course, has to be able to provide wireless connectivity, otherwise, if you do not, there will be no need to try connecting via your AirPort Extreme card.

If your network has been physically set as a wireless network, then just turning on the AirPort card in System Preferences>Network will start discovering all networks within its range, including your own network.

So whether you are using an Airport Extreme, Express or a 3rd party (non-Apple-branded) router, you should be able to connect wirelessly.

If you are still unable to connect with these basic steps, here are a few articles you will need to review from Apple Support informational database:
Requirements for wireless Internet access with AirPort
Airport & Bluetooth interference (for connectivity issues)

So here are some basic steps and resources you can try.

If you have more questions please feel free to post a comment.

I hope this information helps.

The antennas in the Macbook Pros have had an issue with reception due to the aluminum housing of the laptop but, should still receive decent reception just not as much as a plastic Macbook or plastic PC laptop. It could be possible that the antenna's cables have become disconnected from the Airport Extreme card inside your Macbook Pro, that the card itself is faulty or damaged or that the Antennas themselves have been damaged in some way. As always make sure you have the latest updates and have installed any driver updates from Apple regarding your Airport Extreme card. Here's an article that may help eliminate any wireless interference that may be affecting your signal strength. Apple - Wireless Interference hope this helps, if so don't forget to comment, vote, etc. Thank you.

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

Not sure what you have tried yet, so I'll suggest the first thing to try ...
The cable modem will have an ethernet jack on it for "LAN" - you will need an ethernet cable ... plug the cable into this jack .. and the other end of the cable into the airport extreme .. and then power up the airport extreme .. if the airport extreme is new, it will set itself up automatically .. if not new, it might still set itself up automatically - look for a green light on the extreme ... if you have a green light you should be in good shape
Of course your computers have to be in range, say within about 100 feet of the extreme to pick up its wireless signal.
In the MacBook, make sure Airport is turned on - in System Preferences under Network.
Your MacBook should figure things out all by itself and you should be able to connect to the Internet.
On the PC, you'll need a wireless card if you don't already have one ...

You should be able to use the internet simultaneously and each computer should be able to share files if you want to try that (file sharing is turned off by default on the Mac, not sure about the PC)

Good luck!

You need to make sure the wireless card of the Dell is set to the same settings of the Airport. Also, try to ping the Dell under the ipconfig command. If you still have no connection, then you have a problem with the wireless card.

did you try going to printer properties? i think you will most likly find your answer there.

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?

Dear,

Kindly find the AirPort Extreme driver at this location.

Regards,

Have a good day.

At this point you are much better off installing a USB wireless antennae than spending money on an Airport card, cracking open the iMac, and installing it.

USB wireless adapters are cheap, plentiful, and have more capabilities than the generation of Airport cards that were made for G5 iMacs.
