IMac 27": Windows 7 cannot connect to wireless internet

I just installed Windows 7 on my iMac (new model 2011) on another partition, so I now have both OS X and Windows 7, and I cannot connect to my Wireless Network in Windows 7, but I can in OS X.
I've tried basically everything and looked in millions of threads to find a sollution - but I can't. I'm using my laptop now (Windows XP) and it's connecting fine.
I've tried:
- Resetting the router
- Changing the security type from WPA2/TKIP to none
- Updating the driver (In Windows it says it's and Atheros AR938x Wireless Lan Card)
- Update all Windows
What can I do?
Gear:
Router: Netgear CG 2000
iMac 27 (New model 2011 or what it's called. It a year old)
I've read several times that Windows 7 has problems with connection, but the threads are like 2 years old, so someone must have come up with a sollution?
Christian

I've done that.
I've installed Windows 7 with Bootcamp and everything is installed correctly if I look in "Device Manager". There are no problems - except that I cannot join the wireless network.
If I plug a cable in it works fine.

Mac Mini cannot connect to wireless internet

I recently got wireless internet. Before, the Mini worked fine connected by cable. It has never been connected to a wireless before. The wireless router works correctly, my $250 PC connected to it instantly. There is a yellow light on Airport and it automatically populates an IP address, whatever that means. I haven't installed any new software since it worked with a cable, no funky setup or third party anything- it's just a mac mini plugged into a TV I watch Netflix on and that's all. My ISP said it's a problem with the computer, the Mac free support could not fix it. I really don't want to pay for an extended warranty or phone support on something basic that this computer should just automatically do. I haven't tried typing in a manual IP address- I don't know what that address would be. If all else fails, I will just run a cable to it again.

Followup- I just met a computer technician who fixes problems like these for a living. He was in my home and took a thorough look at my setup. He said, due to this computer's design, it will never be able to read the signal that my netgear wireless is putting out- they are not compatible. So this would require a different modem at the very least. He said a Mac laptop would probably work fine, but not the Mini- wireless connectivity is an afterthought of the design in these according to him, whereas it is integral in PC design. But Apple Support does not want to admit this so they say it is a problem with the network.

Cannot connect to Wireless Internet.

Hi guys,
About a year go I turned off 'AirPort' on my Apple Mac Pro machiner and now am trying to re-connect but unsuccessfully.
The 'AirPort' sign is nowhere to be seen. I went to Netwrok Setup Assistant to select the method to connect to Internet but the - 'I use AirPort to connect to the Internet wirelessly' as well as the option of, ' I use a telephone modem to dial my ISP.' are dead and have no connectivity. When I move the cursor on them they're completely unresponsive.
I am trying to simply get my apple mac pro connected to a wireless Internet via AirPort.
This is a Mac OS x Version 10.6.8
Thank you in advance for your time and advice,
Stephen

Hi Grant,
Thank for your time and advice.
I did so but nothing is happening.
I am attaching a screen shot after I unlock, entered name and password.
Cheers,
Stephen

Cannot connect to wireless internet - WLAN card not installed - Satellite Pro M10

Hi, i have just been given a second hand toshiba satellite pro M10 and i have just rebuilt it and put windows xp home edition on it. What i would like to be able to do is to connect to my families wireless network so that i can get rid of all the cables on the floor. My laptop seems to think that there is no wireless card installed though. Now i had the same problem with the cable lan, but i went onto tosibas website and downloaded a patch and updated the driver in device manager. I am not able to do this with the wireless as there are no drivers to download for it and there is apparently no device for it in device manager. Could somebody please help me and tell me what to do and how i can download a patch or fix the problem. Thanks, Andrew Reid

As you can see there are 4 different wireless drivers. (Atheros, Toshiba, Cisco, Intel)
Look what wireless card you have and install the right driver.

I have a Power PC G4 which is running on OSX 10.5.8, it has the AirPort utility but cannot connect to the internet as my iMac can, I think I might need an AirPort Card? Is that the case or do I need something different to connect to a wireless modem?

I have a Power PC G4 which is running on OSX 10.5.8, it has the AirPort utility but cannot connect to the internet as my iMac can, I think I might need an AirPort Card? Is that the case or do I need something different to connect to a wireless modem?

Welcome!
Only one variant of the PowerMac G4 could use the faster Airport Extreme Card. The rest used the original Airport card that is pretty slow.
To get fast wireless without buying more than one thing, consider this:
http://eshop.macsales.com/item/Edimax/EW7722IN/
It goes in an available PCI slot
There are USB solutions also. However, all PowerMac G4 towers had only slower USB 1.1 ports, so any USB wireless adaptor can only run at about wireless 'B" speeds (slow) unless you also install a PCI USB 2.0 adaptor card. Doing that would allow a USB wireless adaptor to run at its maximum rated speed. These items working together would accomplish that:
USB wireless "dongle:"
Newer Technology MAXPower 802.11n/g/b USB Adapter + Plug and play direct or with extension cradle
USB PCI adaptor:
http://eshop.macsales.com/Search/Search.cfm?Ntk=Primary&Ns=P_Popularity%7c1&Ne=5 000&N=7069&Ntt=USB+PCI
Each approach has its advantages. The PCI wireless card is a one-piece solution that takes up no desk space. The USB2 card+USB2 Dongle gives you more fast ports for transferring date from other external USB devices (primarily cameras and external hard drives) at hugely faster rates than can the original ports. I have a USB 2 PCI card in my G4 tower strictly for transferring images from my digital SLR camera in a timely manner.

I cannot connect to the internet. I think I have my settings all out of whack now and need to get them back to the way they were when it was working. (I know my wireless router is working because my Dell has no problem connecting to the internet.)

I cannot connect to the internet on my iMac through my wireless router. I think I screwed up the settings and need to reset them. I know the router is working because I can access the internet on my Dell laptop which is located right next to my Mac.

On your iMac try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
In the windows on the left side: Select login for Keychains and "All Items" for Category.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

How to restart base station from airport utility? I used to be able to do it remotely
I currently use a Mac Pro 10.8.4 and have a time machine for wireless 6.3 (630.34). Sometimes I cannot connect to the internet and use network preferences to diagnose the issue. This results in being told to restart the wireless. The airport utility includes the drop down option of restarting but is not clickable so I can't choose it.
With my prior macbook and same time capsule, etc if i had problems connecting to the internet I would run network diagnostics to help out. This included clicking on the airport utility ---> base station --> restart. This worked most of the time.
Bottom line, is there something I am missing in not being able to restart the wi-fi remotely? ]
Thanks in advance

You are likely forgetting a step.
Open AirPort Utility
Click on the Time Capsule icon
Click Edit in the small window that appears
Now click the Base Station menu.....top of the screen....not the Base Station "tab" in the center of the screen
Click Restart

NB200 Can connect to wireless networks, but cannot connect to the internet

I have been able to connect my Win XP netbook to my secure wireless network at home, other people's networks and public networks like the library and McDonalds. This week I'm away from home and discovered that while I can still connect to a number of different wireless networks, I cannot connect to the internet using Internet Explorer.
I've had this problem once before and fixed it by reinstalling Windows XP and all my other software. I have no idea why it has happened again. I'm hoping for a less drastic solution to the problem..?

Hi Nakia,
> I cannot connect to the internet using Internet Explorer.
Have you tested other browsers like Mozilla Firefox and does this work?
As MasterG wrote try to renew the IP address using the commend line.
Last week I had a similar problem and I could solve it by updating the WLAN driver. Just remove the driver, restart the notebook and install the newest one. :)

My PC can connect to the airport extreme but with encryption it cannot connect to the internet my iMac has no issues, any help.

My PC can connect to the new airport extreme I just purchased but with encryption it cannot connect to the internet my iMac has no issues. If I open the airport exteme up and provide no security everything is fine which leads me to believe it is something with the encryption between the two devices. Not sure what step I'm missing here this shouldn't be this difficult.

Sorry, I should have been more clear. I am asking if the DNS IP addresses, not the IP addresses assigned by the DHCP service, are the same. DNS is like the Internet's version of the Yellow Pages. Your ISP typically will provide them to you or you can elect to use those provided by another source, like OpenDNS.
DNS is the service that translates a website's URL to its actual IP address so that you can access it. I am just trying to rule out that the PC is not configured properly with the correct DNS IP information.
The other thing to check is if the PC is configured to use a Proxy service. By default, it would not be.
Finally, what is the make & model of the PC. More importantly, if the PC is using either a PCI or USB wireless adapter, what is its make & model?

Your Apple TV is connected to your wi fi network but cannot connect to the internet. Airplay logo not available on ipad3, iPod touch3g and showing intermittently in iTunes on windows laptop. Switched ISP a few days ago. Entered pass key info on all.

I switched ISP a few days ago and had problems with airplay since. After restarting and reinstalling and updating, re entering pass keys for new wi fi on everything, Apple TV shows: Your Apple TV is connected to your wi fi network but cannot connect to the Internet. Ipad3 and iPod touch 3G have no airplay icon or get one briefly then it disappears again. Same with itunes on windows laptop.
Can anyone help?
Bob

Welcome to the Apple Community.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

I cannot connect to the Internet after installation of Windows Vista Ultimate edition.

I cannot connect to the Internet after installation of Windows Vista Ultimate edition. For some odd reason, it seems my ethernet has not yet been installed to my operating system and I do not know how to do that even with the internet, I have the LAN cable hooked up to my computer but I do not know exactly what to do about it. Is there some sort of driver I need to install, or what? How do I do that without the internet?
This operating system is on a separate partition to my other operating system that is connected to internet already (Windows Vista Premium) that I do not wish to use anymore because of it's corruption. I tell you this because you may know a way of finding the driver files on my previous operating system that I may be able to transfer to the other.

My iMac is able to use my wireless internet from my airport extreme, however, no other devices(iphone, ipod) will connect. The network shows up, but the indicator just spins without ever joining.

I have tried resetting my airport extreme, creating a new network, etc nothing seems to work.

I have a feeling you may be stuck in bridge mode there...
Factory reset the Extreme (so we don't second guess later), and re-set up the extreme using iOS5 on your iPhone.
Set up your Wi-Fi network with your iPad, iPhone, iPod touch, or Mac.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Just received my T530 and cannot connect to the internet

I just recieved my T530 laptop on Friday, 8/26. Right out of the box, I am unable to connect and sustain any internet connection. I have my other PC tried on two different wireless routers and it works fine. It is not the routers that is the issue.
My computer says I am connected to the internet but I cannot browse. I have enabled the Intel connection under properties. The drivers are all up to date. I have restored the system to factory settings because a Lenovo tech support rep said the Windows update was messing new laptops up.
All of this and I still cannot connect to the internet. I am a wits end. What do I have to do to get this working? Also, how do I return the laptop for a refund?
Thanks!

ladiel,
Typically support will ship a box overnight to you for you to send the system in, and in most cases repairs at the depot are 1-2 days and then it will be shipped back to you overnight.
If you wish to return, you will need to call sales, and let them know you had a defective system and provide the service case number (where you called support to verify your trouble)
I appreciate your time urgency on this.

My iMac won't stay connected to the internet, even though all other computers in my house stay connected

My iMac won't stay connected to the internet, even though all other computers in my house stay connected, and its connection is set up the same way my fiance's macbook is (his macbook is about three years older than my iMac). Every time my computer goes into sleep mode and I come back (even if it's mere seconds after giving the black screen) I have no internet connection. I discovered a workaround for it some time ago, but now that is working less and less, and now my computer randomly disconnects WHILE I'm actively using the internet. Just a few minutes ago, the connection refused to come back until I restarted my computer, even though once again all other computers in the house were connected. The workaround I discovered before and which doesn't work as reliably now, is to click opne Airport at the top right of the screen, click "Open Network Preferences," then click "Assist me," then click "Diagnostics," and wait for everything to turn green again, signalling a connection.

Let's check the quality of your connection since signal strength alone does not insure a good connection. The "bars" that you see at the top of the iMac screen are there pretty much for show.
Hold down the option key on the iMac while you click on the Apple icon at the upper left corner of your screen and select System Profiler
Look down the list of items at the left of the window until you find the setting for Network, then click on AirPort.
In the window to the right, look for any listings of your wireless network name. You may possibly see two listings for the wireless network name.
We need for you to list the information that you see for Signal / Noise. These will be negative numbers. Post back with your findings and we will continue.
In the meantime, please move any cordless phones that you have or any other electronic devices that are near the iMac as far away as possible from the iMac.
If the iMac is located in a corner or an enclosed area, give it as much room as possible since the wireless antenna is on the back of the iMac and it needs to be able to "see" the room.
Anything that you can do to minimize the number of obstructions like walls or furniture etc between the iMac and the wireless router will help the cause as well.
