Wireless 802.11n on macbook with Leoopard

I m using Macbook core 2 duo, 2.0ghz and 1G Ram, with installed Leopard, i do have a problem on installing the 802.11n enabler that i purchase in apple through online, previously as i was using Tiger, no problem when installing it , but after changed to Mac OS X Leopard, the setup did say that it is not compatible with smth... so any brilliant idea from u all ?? thx for helping me yea...

Leopard has the enabler built-in.
Now, whether Leopard works reliably in 802.11n mode is another matter that is being discussed in dozens of threads on this board.

Problems connecting on Wireless 802.11n with my T61 with Intel Wireless AGN

Hi, I live in Thailand and have a similar problem as others with my Intel Wireless AGN connection as others. I have a D-Link Model DSL-2740B Rangebooster N ADSL2/2+ Modem Router. It is supposed to support 802.11n draft wireless connections of up to a maximum of 270 MBPS versus 54 MBPS for 802-11G wireless. Of course, I don't expect it to reach the maximum transfer speed, particularly here in Thaiand, however I would expect it to produce results better than the 54 MBPS rate for 802-11G. I first tried it on my ThinkPad T61 which incorporates Intel® Wireless WiFi Link 4965AGN. When connected, it shows a speed of 54MBPS (802-11G) instead of higher wireless 802-11n speeds. I've upgraded my router to the latest firmware and have tried different configurations with no improvement in performance. One think I have noted is that when I make an on-line configuration change to my router configuration then select "apply", immediately my ThinkPad rate changes to 150 MBPS momentarily then my connection is lost (to be expected as the router changes are being implemented), followed by reconnection of wireless signal only to return at 54 MBPS again. I also have an older ThinkPad model without built-in wireless capability so I purchased a Belkin wireless 802.11n USB adapter to connect to my router. Again, the maximum connection is at 54 MBPS. When I repeat configuration changes to my router as I did above, my ThinkPad connection momentarily changes to only 1 MBPS instead of 150 MBPS as in my other T61 ThinkPad then reverts back to 54 MBPS once the configuration changes have been completed. Has anyone successfully used wireless 802.11n successfully at the higher transfer rates (above 54 MBPS)? Is it possible that my TOT Goldcyber connection speed is artificially limited? I notice that my rated speed for my desktop computer connected to my same D-Link DSL-2740B only indicates a rated speed of 100 MBPS. I use Vista Home Premium 64-bit on my destop, Vista Home Premium 32-bit on my ThinkPad T61, but us Windows XP Professional on my older ThinkPad. I feel that my problem is either with my ADSL carrier (TOT) or compatibility with my D-Link DSL-2740B Modem Router and my ThinkPad T61 internal wireless card and/or Belkin wireless n USB adapter. IT-City is letting me swap out the Belkin USB for the D-Link Rangebooster n DWA-140 USB adapter next week when they restock. The only other think that I can think of is that wireless n just doesn't work in Thailand and that maybe I should just stick with wireless G and go with a higher powered wireless USB model such as the business rated EmGenius EUB 362 EXT. Has anyone used this model and had good success with it; I've heard that it is a long range model and has the capability of reaching 108 MBPS through some sort of magic? Looking forward to reading your replies and possible solution.

Hi!
Intel Wi-Fi cards support full 802.11n speed of 300 Mb/s working at 5 GHz range only. Your D-Link DSL-2740B works only in 2.4 GHz range. So to get 300 Mb/s you have to get another wi-fi router that supports 802.11n in both 2.4 and 5 GHz, for instance Lynksys WRT610N or Apple Airport Extreme or whatever.

Range Extender not working on Wireless 802.11n

I've started a new topic to ensure this gets the correct attention. For the back story see this forum topic. http://community.linksys.com/t5/Range-Expanders/Can-t-find-Range-Extender-after-installing-firmware-...
Long story short the RE1000 Range Extender is not working (connecting, extending) on Wireless 802.11n after the firmware upgrade. As a result the device is not useful because the devices that attempt to connect to it are NOT expecting the wireless level to change and thus just get stuck in limbo land.
My wifi network (as of writing this) SSID is called "SeriesOfTubez" and is broadcasting on b/g/n. However as you can see by the wireless network survey (from the router) all other devices connect on "n" but the RE1000 is only connecting/broadcasting on "b/g" (not "n")
Is there a setting somewhere to force it to use "n" or does Cisco/Linksys need to fix the firmware again to get it right? or do I need to take the unit back to the store and buy another brand that properly supports 802.11n?

Great to hear that, Steve. Keep your eyes open and observe your connection. Don't worry, Linksys Support is available 24/7. I've had a number of great support experiences from them even at ungodly hours!

Airport Extreme 802.11n connectivity issues with Windows Vista

I recently purchased the 802.11n airport exterme base station and set it up using my MacBook Pro laptop. During the configuration process I set the security to be WEP enabled since there are other computers on my network, one of which has only an 802.11b wifi card, that can only accept WEP security protocol. The set up worked great and I was surfing on the internet with my Mac in no time.
When I go to connect to the 802.11n extreme base station with my Windows Vista desktop PC, I cannot get any type of connection. I re-entered the Network SSID to match that on the AE base station and re-entered the WEP enabled password.
Is there a compatibility issue between the Airport Extreme Base Station and Windows Vista? I realize that the base station works on XP based PCs but not sure why it could not work on a Vista machine. Any help anyone can offer would be greatly appreciated.
MacBook Pro Mac OS X (10.4.6) 1.83Ghz Intel Core Duo

Upon further review I determined the flaw with my earlier attempts to set up the airport exterme base station with my winodws vista desktop pc. I realized that I should not use a WEP key but rather a WPA key since the wireless adpater connected to my desktop is a wireless G enabled adapter that can handles WPA and WPA2 security.
Therefore, no issues with Vista and the airport extreme base station. Works great.

Wireless 802.11N

I just read about the Wireless N technology, truely amzing stuff. Just a question, if the technology has been around for so long, why does apple not use it in their laptops?

Did some research into this topic. Turns out some, if not all of the MacBook Pro's with the Core 2 Duo processor have a new Airport card manufactured by D-Link that supports 802.11n. I set my router to just use 802.11n but the MacBook did not connect, I later find out that Mac OS X doesn't have a driver that supports 802.11n.
Maybe Leopard will introduce this new wireless standard.

802.11n for MacBook Pro Core Duo's no problem!

From a post on xlr8yourmac.com:
" So I was really ****** about only having G because of being an early adopter. So I started looking what could I do about it. Browsing the net, I found out that the new core2duo machines actually use a broadcom chip (Actually as mentioned here previously, the Core2Duo MacBook/MacBook Pros use the Atheros AR5008 Chip, although the Mac Pro uses a Broadcom chip (not sure on chip version no.) - the Apple 802.11n enabler supports both. See notes on Mac 802.11n page here.-Mike) and this chip is the same one in Dell Wireless 1500 adapters. (Dell notebook mini card)
I bought one of those Dell 1500 cards on ebay, (I searched google and found the Dell 1500 card for as low as $52.xx, although an ebay auction had over 100 of them at $90 "Buy it Now" price.-Mike) and using the great guides on ifixit, change the card on my machine.
(He didn't mention which CoreDuo Mac he had (Macbook? Macbook Pro? iMac? Mini?) but I'm assuming a Macbook or Macbook Pro since iFixit's guides don' t cover the intel-based Mini or iMac.-Mike)
On boot, the card is recognized (and even more stable than the older one). The enabler didn't want to work (wouldn't install I assume he means) on my system though. So I opened it in pacifist, (available here-Mike) and moved the file to the System folder, and magic! I have draft-N in my macbook coreduo
Hope you can publish this and it helps someone.
-Julian"

Just out of interest, where's the third attenna?
802.11n might work on the chip, but you won't get 11n
performance without the third attenna.

Ok, here is the scoop, I installed the AirPort Card from a Mac Pro and it works fine. I do have an issue with my Verizon DSL router Westell 327W. It does not like the new card. So I can not connect to it. On the other hand the AirPort Express and the new Mac Pro card in the MacBook Pro love each other. The range is unbeliveable! I am reluctant to update to the 802.11n enabler right now since reading all the problems with it in the other discussions.
I am going to disable the wireless feature in the Verizon router and hard wire a connection to the AirPort Express and see how that works...
So MacBook Pro (Core Duo) first generation can be updated to take advantage of 802.11n.

How do I achieve 802.11n (5 GHz) with new TC?

I'm mainly using my new TC to stream 720p .mkv files to my PS3 using "PS3 Media Server" application. Everything is working perfectly at the moment i.e. I can stream a .mkv file (after some QT modifications) which is 6000 kbits/s and there's no sign of jerkiness.
When I open AirPort Utility and go to "Advanced" and then click on "Logs and Statistics" and then select "Wireless Clients". In the "Type" section it just says 802.11n only (2.4 GHz). Now I presume something is auto selecting this as the speed?
My Time Capsule is the dual band one and it only lets me select ranges. The fastest I can select is "802.11n (5 GHz) - 802.11n only (2.4 GHz)". I know I have to "Alt" click to bring up the extra options. I cannot just choose 802.11n (5 GHz). Is this because my IMac is to old – 2.8 GHz Intel Core 2 Duo? Does this IMac only operate at 802.11n (2.4 GHz).
I'd like to be able to look (in Advanced > Logs and Statistics > Wireless Clients > Type and see the speed is 802.11n (5 GHz). I'd like to try and stream something with a higher bit rate and feel that it will work better at 5 GHz? Is this possible with my current set up?

My Time Capsule is the dual band one and it only lets me select ranges. The fastest I can select is "802.11n (5 GHz) - 802.11n only (2.4 GHz)". I know I have to "Alt" click to bring up the extra options. I cannot just choose 802.11n (5 GHz).
That is correct as you will only have options to choose modes for BOTH radios. To the left of the hyphen is the 5 GHz radio; to the right is the 2.4 GHz radio.
Is this because my IMac is to old – 2.8 GHz Intel Core 2 Duo? Does this IMac only operate at 802.11n (2.4 GHz).
No, the earliest iMac with the 2.8 GHz Intel Core 2 Extreme processor was equipped with a built-in AirPort Extreme card capable of 802.11n on both radios.
Did you enable "Use wide channels" for the 5 GHz radio? (ref: AirPort Utility > Manual Setup > AirPort > Wireless > Wireless Options > Use wide channels)

Broadcom Wireless 802.11n low Mbs speed

Hello All,
I just picked up a refurbished G500 and overall I'm pretty happy with it...with one major exception. The #1 criteria when I was laptop shopping was that it provided 802.11n support (my old laptop was just 'g').
Anyway, long story short, I am not experiencing any connectivity issues however I'm lucky if I connect at anything above 55 Mb/s. I switched over to my 802.11g router and my connection speed dropped down to 5 mb/s... so there is obviously an issue.
All suggestions are welcome, but let me rule out the typical initial responses:
* I have a Dell laptop that connects to my 802.11n router at 150Mbs so I know the router is fine
* I have tried the generic Windows Broadcom Driver
* I have tried the Lenovo Broadcom Driver for Win 7
* I have tried the Lenovo Broadcom Driver for Win 8
* I have tried the Lenovo Broadcom Driver for Win 8.1
Also note that I'm in I.T. but wireless isn't my strong point. When I first got the G500 before I did anything to it (so OEM image) the wireless connected low (Think the highest I saw it was 72 Mbs at one point).
I have since wiped that laptop and installed my own copy of Win 8 Pro (and then Win 8.1 Pro Update) and still getting the same speed.
So I feel like I have pretty much ruled out any OS issues (since I've been on 3 at this point). Drivers are always a possibility but I've tried everyone out there. And of course Hardware would be my last thought although it works.. just not that fast.
I'm also wondering:
* Is this card (Broadcom vendor Device ID 4727) even able to connect at that speed.
* Is the G500 wired with the required antenna's to get even 150 Mbs. From my understanding you must have 2 in and 1 out to get 150 but I could be wrong.
Oh, and as a last resort, would just replacing the stock WLAN with a better aftermarket be an option?

I have same problem with you when first use Broadcom 11n wireless card (only got constant 39Mbps). But I've fixed by changed wireless channel in wireless router to less intensity channel (1 or 2...) and set Broadcom driver option "Bandwidth Capability" to "11b/g:20/40Mhz". After that I can get wireless speed from 135 Mbps to 150Mbps.

Airport Extreme 802.11n and WDS with 802.11g express

I have an 802.11n Airport Extreme that I have been using with my AppleTV. I have it set to allow for 802.11b/g, since I have an old Powerbook Titanium that cannot be upgraded.
I recently decided to add my Airport Express 802.11g to the mix to act as a bridge for a remote, wired computer. I did this by enabling WDS on the Extreme/Express.
My question is this: by enabling WDS on the extreme, will the AppleTV still be able to connect at 802.11n speeds, or does it get pulled back to 11g? Is there any way to verify/check this on either the Extreme or the AppleTV?
Thanks,
keith

You can check the connection speed of each wireless client attached to a base station using Airport Utility. Launch Airport Utility, click on the Airport button in the toolbar. On the Summary tab you'll see an item called Wireless clients. It shows you how many wireless client devices are connected to that base station.
Click on the words Wireless Clients and you'll get a graph and a list. The graph shows the signal strength of each client. The list shows the client's wireless MAC, the signal and noise levels and the rate at which each device is communicating. On my Extreme-n base stations, I regularly see rates from 1 to 130 and everything inbetween. It looks like each device runs at it's best rate based on signal strength and error rate.
Assuming you know the MAC of your Apple TV (it's on the serial number label) you can see what wireless data rate it's getting this way.
The thing I've noticed is that my Extreme-g base stations seem to connect to clients at higher average rates than my Extreme-n units. In other words, on the g units I'll see more clients at 54 (the max) or 48 and on the n units just a couple will connect at 130 or 54 but most are at lower rates like 27 or 11 (even 2 or 1), even when they are in the same room as the base station.
I find that very odd and would like to understand it. Anybody have any ideas?

Compatible Gigabit Wireless 802.11n Routers?

Hi,
Is anyone aware which currently available routers with gigabit ports & 802.11n are proven to work with .n enabled MacBook Pros?
I realise that depending on where you are in the world, not too many are even on the market as yet but I've read about a few, namely the Linksys WRVS4400 and the D-LINK DIR655 which are available but I can't find out if they will actually work with the MacBooks. Linksys are also bringing out what look like 2 great routers in the near future (WRT350N & WRT330N) but again, who's to say if they will actually work with non-Linksys kit.
Any experiences appreciated.
Cheers

Z61p wireless 802.11n

Hello,
maybe someone knows is it possible to upgrade my thinkpad with wireless card which support 802.11n?
If it is, where could I look for more info or maybe someone even knows wireless card part code?

AFAIK, Z61p was never offered with a "n" card.
Now, you can get around that with a modded BIOS. However, I haven't seen one for your machine type anywhere.
Good luck.

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.

Wireless 802.11n card for iMac G5

I am running a 802.11n wireless network (linksys) with WPA Personal security. Is there any USB or internal adapter to allow a wireless connection to my home network. I have a iMac G5 Power mac 8.2 and the airport card worked fine with the g class network? Apple's official stance is that they do not provide or support any external or 3rd party device to assist. They suggest I drop back dwon to a g network. So much for cutting edge...

rottencore, Welcome to the discussion area!
There is no internal solution. For an external USB solution, look at Quickertek.

Is wireless 802.11n better than Draft-n?

I have altered my network following new supply of optical-fibre connection and have found a speed slowdown which may be due to one old Airport Express in the network which is rated as 'Draft-n'. Will it be worth upgrading this unit to a new on rated as 802.11n?

Will it be worth upgrading this unit to a new on rated as 802.11n?
Not really, if this is all that you are looking at, since the standards adopted were essentially the same as "Draft-n".
However, the dual band capability of the new Express will allow you to use both the 2.4 GHz and 5 GHz bands simultaneously. If you are using dual band AirPort routers elsewhere on your network, the new Express version will provide the same simultaneous dual band wireless performance.

Is the 802.11n download compatable with my Mac Book Pro?

I have a Mac Book Pro with a core duo processor. I was wondering if I could purchas the $2.00 download and make my computer 802.11n compatable. I dont know if I need to get anything new, say a different airport card, or if I can just download the "new" software.

You'd need a new Airport card or ExpressCard for 802.11n. But if you just want it for Internet, don't bother, only for local file transfer, e.g. Time Capsule.
