Imac Windows 7 802.11n problem

I have an imac 27 late 2011. I have windows 7 running on it. Also i have ASUS router that supports 802.11n up to 150Mps. When i'm trying to set up my router to "n" mode, my imac refuses to connect, saying "couldn't connect to network". In a meantime other devices work flawlessly with the network. So i have to put my router back to "b/g" mode to allow my Imac to use internet, which is very sad bc i have 100Mps internet connection.

Hi,
the usual way of choosing which operating system to boot is to hold down the 'alt/option'-key during boot to get to the Startup Manager.
To boot from your OSX installation DVD you can also use that key or alternatively the 'C'-key.
Once booted from the DVD choose your language and then from 'Utilities' in the Top Menu run Disk Utility to see what is really on your harddisk.
There is the possibility that during the Windows 7 installation you somehow deleted your OSX form the harddisk.

WRT120N 802.11n problems

Hello!
I just bought a new WRT120N Router. It worked perfectly wired and wirelessly.
But my old laptop burned, and the new one came with a Atheros AR5B93 Wireless Network Adapter, which is Draft-N compatible.
The laptop connects to the router fine, but using only the G type. When I set the router to use only 802.11n, i get a message from Windows, like: "Windows was unable to connect to the network."
Please help me solve this problem, because the N configuration is much faster than the old G.
Thanks,
edydotmail
Solved!
Go to Solution.

How you come to know that the computer is connecting with G type....?
Try to adjust the settings on the router..Open the linksys setup page,Change the Channel Width to 40MHz only,Wide Channel to 9 and Standard Channel to 11-2.462GHz and click on save settings...Under the Advanced Wireless Setting,Change the N Transmission Rate to 7-65 Mbps,disable the Frame Burst..Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"... Now,check...

Airport Express 802.11n problem

I have an Airport Express 802.11n.
I use it to send iTunes from my mac on my stereo system in the adjacent room, via my wireless network. I don't use it all that often. It has worked fine over the two or so years I've had it
A couple of weeks ago I had a new BT Home Hub 5 installed, this may be just a coincidence but I tried to use my Airport Express 802.11n yesterday with no luck. All I get is an amber flashing light. I've plugged the Airport Express 802 into the mains right next to my imac but that has not helped. My Airport Utility doesn't find or show my Airport Express.
What do I do? Can anyone help?
Hopefully
Rob

Here's an update:-
By re-setting my Airport Express 802 and updating the firmware, I can now get it to work when connected with an ethernet cable and changing my settings from DHCP to Bridge.
However, I still can't get it to work wirelessly.
Is this a known problem with the BT Home Hub 5 and BT Infinity?

IMac 24'' & 802.11N

Hi,
I've bought an iMac 24'' in June (White on), I would like to know if it has 802.11n compatible card in it ?
Thanks

Yes, the 24" iMacs have a "Core 2 Duo" processor.

Basic Intel iMac with 802.11n - no mobile devices or broadband. What do I need in Australia. mrcos

Saturday 7 January 2012
I am writing to ask for some advice regarding the best course of action to take with regard to my current computer situated in Sydney Australia.
I have been a Netspace customer for many years with an old iMac until I purchased a new iMac in the latter part of 2011. All this time I have been a dial-up participant with no broadband, gaming or little or no downloading. This account will expire late next month.
My main usage has been in the areas of email together with internet access mainly to my financial interests. I am still using dial-up after purchasing an exterior V92 modem which can only operate in 32 bit mode rather than the 64 bit mode for which the new iMac normally operates.
The advice I need now is with regard to the best method I should now adopt in order to take advantage of the facilities I now have available and whether or not I need more hardware and/or software, to utilise such things as wireless using 802.11n.
Should I stay with Netspace or switch to another server such as Telstra who already have my home telephone and Foxtel accounts.
I intend to make similar enquiries to Telstra, Netspace and other suppliers.
Unfortunately, I am an old dinosaur and am enquiring because I have not been bothering to keep track of what is available until my latest computer purchase posed a number of questions as well as my own ability to take it all in.
I have no mobile devices and do not require any nor am I particularly looking for broadband.
Yours faithfully,
malfromsydney

Hi Peter Ducklow-

IMac Windows 7 Bootcamp Problem

Hi,
I tried installing Windows 7 on my new 27" iMac using Bootcamp. When I installed, however, the installation did not complete successfully. This is because after the initial setup, Windows can't seem to continue and doesn't get onto the "Setting up for first usage" screen - I just get a black screen, and the iMac reboots after several minutes.
When I reboot, it goes straight into this setup so I cannot enter Mac OS X.
The Windows 7 installation CD is also stuck inside of the iMac, which can't seem to be removed. No shortcuts or anything seem to be working because it never starts loading Mac OS X - It starts with a white screen and then tries booting to the Windows 7 CD without the Apple logo. I can't boot into anything because I can't remove the disk.
Has anyone got any ideas? This isn't a nice situation.
Thanks,
Jake.

I have read that my Intel Core 2 Duo 24" iMac has 802.11n wi-fi support built in but that it will cost me $1.99 (£1.01) to download the software which will enable me to step up from 802.11g.
Where can I find this software in order to download it?

It is avable to download for £1.25 from here http://store.apple.com/Apple/WebObjects/ukstore.woa/61114042/wo/Xl7rAaWLyyhW2MQh 7OxuC6m56TZ/1.0.21.1.0.8.25.7.11.1.3

How can I get my AE to work in 802.11n mode with my dlink router?

Hi all,
I have a dlink 655 wireless n router that I use for my network and a recent AE with 802.11n capability that I use to connect iTunes to my home stereo.
I have a mix of computers at home and only my imac has 802.11n capability. I work alone in the day so to speed things up, I change the wireless setting on my dlink router to 802.11n only mode. Normally, it is in a mixed mode of 802.11g/n for the other non n computers on the network.
My imac connects fine when in 802.11n only mode but the AE looses connection. As it is 802.11n capable, I was wondering why this happens?
I tried checking Airport Utility for a 802.11n only mode or something similar, but didn't find anything. Will the AE only work in 802.11n mode when on the 5ghz frequency? if so, that would explain why it doesn't connect with the dlink 2.4ghz router in n mode.
Any ideas?? Thanks!

Hi. Thanks for the reply. It turns out that the router was not going into n mode because of the security I set on it. I finally figured this out and the AE did connect in n mode after all.
Well at least it's working now but I feel a little bad for posting when it was my fault!!
Cheers!

Enabler won't enable 802.11n

I am installing an Airport Extreme and upgrading 2 iMacs to 802.11n.
The first iMac went great - it shows that it is n-enabled.
The second iMac, newer and it is Core 2 Duo, won't n enable. I did all of the updates - I'm on 10.4.8 - and there are no error messages.
This is driving me nuts - what can I do.

I am determining that the n has not been enabled by launching Network Utility - Info - Network Interface (en1) shows 802.11 a/b/g. The other iMac is showing 802.11 a/b/g/n.
I ran the installer (the CD that came in the package. It shows that it is installing the Airport Extreme Update 2007-001 (I've also downloaded this separately and installed it alone).
The enabler will allow the 802.11n of the wireless network card to be usable. I need the range and hopefully speed boost that the 802.11n is supposed to deliver.
Anybody else have any ideas????
Thanks,
Mitch

Apple Airport 802-11n connection problems with Windows 7

I'm basically a MAC user, but my son is trying to get his Windows 7 Toshiba laptop to connect to my Apple 802-11n wifi. It will see the wifi, but when clicked on my network the connection fails before I get to input the password. Yet neighborhood 802-11n connections get to the password screen. The lap[top is a Toshibe satellite L755-S5107 running Windows 7.
I'm not very savvy on PCs, so I don't know where to look for versions of his software et al.
Anyone familiar with such problems?

Toshiba may be doing something different than other manufacturers, so your best bet might be a Toshiba support site.

Another source that may of some help is the Windows troubleshooting guide for WiFi connections:

Not sure how much more help that we can provide on an Apple support site for Apple wireless routers.

Very slow 802.11n. 20" iMac, Vista, Broadcom, Belkin N1

I've been trying to get some drivers working with Windows Vista. I'll post the results I've been having and maybe someone can assist.
I have a 20" brand new iMac with Leopard running bootcamp windows vista ultimate. When I connect to a Belkin Pre-N wireless router I get 802.11g wireless speeds(expected) of about 36mb/s (it's a good distance away, 2 bars).
I have another wireless router Belkin N1 wireless and I get differing wireless speeds/connectivity depending on what drivers I use. I have 5 full bars and an "excellent" connection rating for it.
I understand that the specifications for 802.11n that both belkin and apple use are based on draft specifications and may not be compatible.
The drivers on the leopard disk are marked as 4.80.75.0. I can connect using those and use the internet. But at very, very slow speeds (27.0 mb/s Broadband tests show .5% of normal speeds for my provider, a wired connection will get 105.8% of normal speeds for my provider.)
I got some other drivers that were posted by other users at the following location
(http://www.versiontracker.com/php/dlpage.php?id=115683&db=win&pid=149836&kind=&l nk=ftp%3A%2F%2Fftp.support.acer-euro.com%2Fnotebook%2Ftravelmate_2480%2Fvista%2F Drivers%2F802.11b%2BgBroadcom+Wireless+Lan+Driver4.102.15.61.zip)
Those drivers are marked as 4.102.15.61. It will connect 1 out of 7 tries at 270mb/s but will disconnect after a few seconds.
There are some other drivers posted by another user at the following location:
http://discussions.apple.com/thread.jspa?threadID=1309942&tstart=0
These are marked as 4.150.31.0. Same issue as the ones on the leopard disk. I get connectivity, but at very slow speeds.
I believe I have the most up to date firmware for my router but will check that and post on the message board some results. Another option that I have is to completely disable the 802.11n protocol on the router and just use 802.11g.
Does anyone know any other drivers out there that I could try? I will post findings. Again this is only a problem while trying to connect to a Belkin N1 wireless router. I get much better speeds/connection using a Belkin Pre-N router.

I have a 24" Core 2 Duo iMac (2.4 GHz, 4 GB RAM) running Leopard and an Apple Airport Extreme base station, and am having the same problem with slow wireless speed under Vista Ultimate edition with Boot Camp. All Vista software updates as of March 11, 2008 have been applied.
I've reinstalled the driver from the Leopard disk (no effect) and updated the driver directly in Windows, using the one that Windows detects automatically (no effect). Under OS X, I get close to optimal bandwidth over the 802.11n connection to my cable modem. The Airport Extreme is set to use 5 GHz only and does not use the 802.11g-compatibility mode.
When I use a wired connection to my gigabit Ethernet switch, everything is fine.

AirPort Extreme (802.11n) & Epson CX3100 Printer Problem

I recently purchased the new AirPort Extreme 802.11n and tried hooking up my Epson Stylus CX3100 to it. It detects the printer but it only prints the first few lines then stops. I check the status window of the printer and I see no error message whatsoever. I have to turn off the printer to force the paper out. The printer prints fine when connected directly to the iMac.
I was using the Gimp printer driver found in my iMac. Since that didin't work, I tried installing the new Intel drivers from Epson. But when I try adding it to me AEBS using the official driver, I get an Error: -9672 message.
I've already updated my AEBS's firmware to 7.1 before I tested the printer, so I'm not sure if it's a firmware issue.
Any help would be greatly appreciated.

Your iMac isn't receiving an IP address at all - the 169.254.x.x is "self-assigned" and indicates it is not receiving the IP address from any router. That won't work.
I'm not sure what you intend to do with the Express so leave it unplugged for now. Use Airport Utility, select your Airport Extreme, click "manual setup", then click the Base Station tab. Note the name of the wireless network it's creating.
Then click the Wireless tab. Make sure the Wireless Mode set to "create a wireless network". Next, consider using no Wireless Security at all, until you've sorted out your problems.
Next, click the Airport pane, then click the Internet pane, then click the Internet connection tab. Next to "Connection Sharing" select "share a public IP address".
Click the TCP/IP tab. Configure IPv4 "using DHCP".
Click Update and let it restart.
Make sure your iMac is connected to the wireless network created by your Extreme. It should then get an IP address of 10.0.1.1 and you should be able to connect.
If this works then we can configure your Express to do whatever you want it to do. If it doesn't work write back and we'll try to figure out what's wrong.

Can anyone recommend a good 802.11n card/usb adaptor for a Windows PC?

I'm about to buy a new iMac and an Airport Extreme Base Station, and I would like my wife's Windows XP PC to be able to take advantage of 802.11n, as the base station will be in the living room and our office room (where the new iMac and the PC live) gets a terrible reception with 802.11g (thick interior walls being the main problem).
I've had a look online at various USB/PCI products, but can any of you recommend one that works particularly well with the Airport Extreme?
Perhaps the Airport Express would be the best solution, as my wife's PC has an ethernet card, plus we also have a USB printer in the office that we'd like to share over the whole house?

I would agree with that, go SATA if you're an island. That's what the majority of my system is set up with.
However, I also have a DSR-11 connected via firewire, and I get firewire drives shipped to me by clients, so I need an additional firewire bus. I bought the cheapest fw400 card I could find, and haven't had any issues yet. I think I spent $35 at CompUSA.
Are there issues that would make me want to buy a better card?

Broadcom 802.11n Network Adapter not working on Windows 7 64bit

As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium. I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve. This however just cropped up after two months of successful use. Yesterday it started failing to connect to the internet, telling me that no wireless connections are available. I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360. I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared. When I reboot my laptop, all I get is a notification that no networks appear in range. If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time. I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that

Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
already connected to a wireless network on startup.
I.a. Disable Device sleep on disconnect
Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
well.
Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
2. Double-click on Network adapters.
3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
4. Click on the Advanced tab.
5. Select Device sleep on disconnect.
6. Set the Value to Disabled.
7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

Windows 8 and Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC

Hi!
I hava a Toshiba L650 - 107 PSKI JE and I am having a problem with the my wireless network adapter on windows 8.
My network adapter is Realtek RTL8191SE Wireless LAN 802.11n PCI-E NIC and works fine on windows 7. Two days ago I formatted my hard drive and install windows 8. The problem is that for much drivers I keep installing, The wireless keep turned off. There's no way I can move the slide from off to on.
I already tried a lot of drivers from toshiba and from realtek but doesn't work.
I went to see the Network Connections (Control Panel > Network and Internet > Network Connections) and the Ethernet is fine, I connect a cable and it is fine, but wi-fi says "Not connected".
How do I solve this problem?

Satellite L650-107 (PSK1JE-00P003EP)
Downloads here.
A computer from Portugal? (Specifications attached.)
This driver should work on Windows 8.
Realtek Wireless LAN Driver
But your problems may be more fundamental. Prior to loading Toshiba-specific programs, you probably need to install something like this.
Toshiba System Driver - Windows 8 beta
And for the function keys to work, you'll need still another Toshiba utility.
