Cannot connect 802.11n on MBP 2.66 Intel i7

The router is a TP-WDR4300 with dual band 2.4G & 5.0G. None of them can be connected to "N". If I switch the network to "N" only it will say "Connection time-out".
Tried to search over different forum but still no clue. But I found something very confusing which is the information about the Network Utility(802.11 a/b/g/n) is different from the System Information (802.11 a/b/g).
Anyone having the same issue? My other mobile device like iPad & Galaxy SIII can connect to the 5.0G "N" network which is way faster than the MBP...
Please help!! thanks in advance!

Try turning off the Bedroom AP. If you are connected to two AP's then the speed defaults to the slowest.

802.11n only MBP connects new MP not

When I set the Airport Extreme Base Station to 802.11n only (5GHz) then my MacBookPro (2009) does connect wirelessly, as do the other Airports in the chain. But my brandnew MacPro (mid 2010) does not. Is it possible this one works on 2.4 GHz only and does not recognize the 5 GHz band?
I read something about some Airports being dual band. How can I find out if mine fall in that category?

Something strange seems to happen here. First time I changed to 5 GHz the other AX's in the chain reconnected. But the MacPro did not, even when trying to reconnect with network Name and Password. Then, changing the network from a closed network (Name has to be known) to one that can be seen, suddenly the MacPro did connect to the Airport network. Is there an issue with networks in closed status? (Wireless>>Wireless Network Options>>Create a closed network).

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.

IPhones will not connect 802.11n

I am new to the airport family so my appologies if my problem has been solved (I didn't find anything searching) or if its obvious and simple.
I currently have an airport extreme broadcasting a 802.11a/n - 802.11b/g wpa2 network. I also have a wired express creating the same network to extend it (thanks for the help with that, Bob).
First, i noticed that my MBPs were connecting to the N network but only 2.4ghz, so I set it to broadcast a separate 5GHz network name. after that, the MBPs were connecting to the 5ghz network without a problem.
So, when I check the clients on my network, I notice the iphones ( 4 and 4s) in the house are only connecting on 802.11b/g not a/n. This happens even if the iphones are only a few feet from the router.
Why are the iphones not connecting on the n network? Is this a setting issue or simply part of the technology I am misunderstanding?
Thanks.

sorry. I didn't mean to disable SSID broadcast; my experience with doing that is it has never mixed well with my macs. SSID broadcast is enabled.
I was referring to when you enabled the setting on the wireless tab in the "wireless network options" dialog box that will enable broadcasting a second SSID for a 5ghz only network (along with your regular SSID broadcast). For example, the two broadcast SSIDs would be;
     phil178821 (which is set to 5ghz n and 2.4ghz b/g/n)
     and
     phil178821 5Ghz (which is 5ghz N only)
What I was trying to described before is if I am sitting close to my router (15ft) and I am broadcasting just one SSID (my normal 802.11n - 802.11b/g/n), my MBP will connect to the 5ghz 802.11n. If I moved up three floors in the house, my MBP will change connection to 802.11b/g/n. With that, my understanding is that it is now connected via 802.11n 2.4ghz. Because it defaulted to the 2.4ghz frequency, I figured I was out of range of the 5ghz network. However, if I go into my AE settings and enable broadcast of a second SSID for a 5ghz N network (as described above), my MBP will pick it up at full strength and connect to it.
So I guess my question is. Why will the MBP opt for 2.4ghz when I broadcast one SSID, if I know 5ghz is still in range since the MBP will connect to it if I enable it with a second SSID in the AE options (recall, the MBP will chose the 5Ghz frequency closer to the AE, e ven when only one SSID is broadcasted)?
hopefully I am explaining this well enough. Thanks for your help.

A "stock" way to get 802.11n on MBP Core Duo?

Is there anyway to get something to upgrade my Core Duo MBP to 802.11n without using an external card or anything like that. I can handle working on the software side of things but not the hardware. Is there anyone that i can send it to to have them to the upgrade for me? Thanks a lot.

what about a third party company, would any of them
do it?
Hi, I'm an old Navy retired electronics technician and have been working on Macs since 1986 and am in the same boat as you. I have a 15" MBP that I have already taken apart once to install a larger Hard Drive and Williams procedure doesn't look all that more difficult. I have the card on order from Powermax and I expect to install it by the end of this week. If it works out for me and testing shows it works consistantly and if you are willing to trust me with your "baby" for the time it takes to install it and ship it back I would be glad to do the same for your machine for a small fee. If you are interested, contact me at my email [email protected]

Slow wireless connection 802.11n AEBS and Intel Core 2 Duo MacBook Pro

I have three Macs all currently connected wirelessly to the new 802.11n AEBS.
Mac #1 - PowerMac G5
Mac #2 - 17" MacBook Pro Intel Core Duo
Mac #3 - 15" MacBook Pro Intel Core 2 Duo
The wireless connection speed (when using the web browser) is fine for both Mac #1 and Mac #2 but noticable slower for Mac #3. All three Macs are sitting right next to each other. All three Mac are getting an excellent signal. All three Macs are running the same version of the OS. All three Macs have identical network setting (as far as I can tell).
When connecting Mac #3 to the AEBS via an ethernet cable, performance is good. I've also tried configuring the channel manually in the AEBS to channel #1 but this did not help (seemed to help others in a different thread). Additionally, I ran the 802.11n enabler and performance was bad both before and after its installation.
Any idea why the Intel Core 2 Duo MacBook Pro would be performing differently?

Ok eveyone. I did some digging and was able to get the network speed back with my Core2Duo machine. I put the Airport Extreme into Bridged mode and connected the Ethernet cable to one of the LAN ports, not the WAN port. After that everything works great. for more information check out this lengthy thread...

Apparently the new base stations have a few issues that need to be worked out so I'd consider this a workaround. There should be no reason to have to do this. Good luck.

Advanced-N 6200 in T510 will not connect 802.11n

I have just received my T510 with the 6200 wireless adaptor. This adaptor will not connect using wireless-n, only wireless-g. I am running Windows 7, 64 bit. Other devices that I have are connecting using wireless-n to the same router.
The driver is the latest (13.3.0.24) and 802.11n mode is shown as "Enabled". There does not seem to be a choice for wireless-n in the "Wireless Mode" selection list.
Is it possible to get this to work with wireless-n? If so, any help would be appreciated.

This is a well known problem with 802.1n kit, that unfortunately many of the WiFi kit vendors are genrally reluctant to warn users about.
The Intel 6300 WiFi card is fully 802.11n compliant, so it is not the issue. Basically that means it should (and will) only connect in 802.11n in the 5GHz band WiFi band on its default settings.
It will also generally connect in a "Super-G" like mode (about 130Mbps raw link speed) in the 2.4Ghz band to a router than offers 802.11n connectivity solely on the 2.4GHz WiFi band, but this is not a fully specified mode of operation.
From draft 2 of the 802.11n spec onwards, the use of 40Mhz bonded chanels in the 2.4GHz WiFi band has been strongly discouraged, as it is generally anti-social in areas with a lot of 2.4GHz WiFi networks operating concurrently.
Your other devices may be operating on the now long out of date initial 802.11n spec, which permitted 40Mhz bonded channel operation in the 2.4Ghz WifI band.... before wide-spread practical field use indicated how disasterous it was for many existing 802.11b and 802.11g WiFi users.
Essentially, you need to get a dual band router that supports 802.11n operation in the 5GHz Wi Fi band (which by the way is actually around 5.8GHz).
Cheers,

Airport Extreme 802.11n upgrade options for early Intel Core Duo iMac

I have an iMac from mid 2006. I recently purchased a Timecapsule - partly for the wireless back ups, and partly to upgrade my wireless network to 802.11n. There is a software upgrade from Apple that upgrades older 802.11 a/b/g Airport cards in the iMac to 'n' standard. Here is the link:
http://store.apple.com/uk/product/D4141ZM/A?fnode=MTY1NDA0Mg&mco=MjIzMDkzNA
The page states that the upgrade is compatible "If you have a Mac with an Intel Core 2 Duo processor (except the 17-inch, 1.83GHz iMac)". What it doesn't tell you is that if you have an early version of the iMac (pre-Sept 2006) that shipped with the Intel Core Duo Processor (note - not the Core 2 Duo) then the upgrade will not work. I have also tried to install Airport Extreme updates (2007002 and 2008004) and these report that the hardware is not compatible. Doing some searching around these forums and others, the issue with the original Core Duo iMacs not being upgradeable to 802.11n is out there - shame Apple weren't more explicit.
I have seen that there are various USB based 802.11n adapters available. Whilst searching on this topic, I also came across a site offering various Mac upgrades, including an upgrade to the Airport card to upgrade wireless capability from 802.11g to 802.11n. It looks like a straight replacement for the internal card - link here:
http://www.macupgrades.co.uk/store/productinfo.php?productsid=461
The company offering this is in the UK, but the product appears to be from a Sonnet, a US company. Does anyone out there have experience of installing this product (or having it installed) and can you comment on how it performs? Is it a seamless replacement for the original Airport card?

What it doesn't tell you is that if you have an early version of the iMac (pre-Sept 2006) that shipped with the Intel Core Duo Processor (note - not the Core 2 Duo) then the upgrade will not work.
If it says you need to have a Core "2" Duo processor, then it seems to me they are telling you very clearly that it will not work with the earlier Core (no "2") Duo iMacs.
The "late 2006" iMacs with Core 2 Duo (except for that one education model they mentioned) have wireless networking hardware that is 802.11n capable. When they were initially sold, Apple chose to NOT enable the "n" capability for some reason; maybe because the standard was still in flux and not enough testing had been done with the driver. Later, they enabled the "n" capability with a firmware update. But that was only possible because the wireless hardware was already capable of doing "n."
Earlier iMacs do not have this hardware so there is no way to enable it with a firmware or software update. 802.11g is plenty fast enough for Internet access (you won't notice a difference with "n"). If you are using Time Machine over wireless, it may take a while longer to do that initial backup (you could connected it by Ethernet cable when it is doing that initial backup), but subsequent backups are incremental, so the "g" versus "n" speed difference will not be as critical. Since your iMac is Core Duo (32-bit) and the future of Mac OS X is 64-bit, especially after Snow Leopard's release, it may be best to save your money and keep your iMac intact (not opened).

Cannot connect from Mac Pro late 2013 to Macbook Pro

Cannot connect from Mac Pro late 2013 to Macbook Pro . I have tried via ethernet and wifi. I can connect from the MBP to the Mac Pro but not vice versa. I have tried to connect to other MBP's on the same network with no luck. I try and connect as a registered user, as I usually do, with no luck. When I enter the Username and then Password the box vibrates as if the details are incorrect, they are not however.
Thanks in advance
Jeff

It is 'just not working' again.
To answer you question. Other sharing services work. I can connect as a guest. I can share screens. I cannot air drop.
I cannot connect either way now i.e. from Mac Pro to MBP and vice versa.
I cannot connect to my wife MBP either. My wife cannot connect to my Mac Pro.
It neither works with wifi or ethernet cable.
I can connect to my Time Capsule directly and Time Machine backups are working.
The passwords are 100% correct.
The Mac Pro is a late 2013. Does anyone else have a similar problem? I have never suffered this one before. Seriously effecting my workflow
Thanks

MBA 1 and 802.11n

I have an MBA rev 1 and just bought an iMac 3.02GHz. Both sit within 10 feet of each other and less than that of the Apple airport. I've just upgraded my internet connection to a 4Mb line and both are connected wirelessly. However the MBA rev 1 is pulling about 75kbps max whereas I'm getting 380kbps off my iMac (download speed).
Why is this? Is my MBA not connecting 802.11n and only b or g or can anyone suggest another problem?
Really appreciate any help - warranty is tuning out in less than 2 weeks..
Thanks!

No answers but FYI (anyone reading this) have since had the MBA looked at and there is no apparent problem with the wi-fi. Further testing reveals so many inconsistencies when comparing against my iMac. I did note though that in removing the MBA from one of those plastic clip on cases, did seem to positively affect the speed.

Airport Extreme 802.11n Enabler wont install

hi,
i just bought the Airport Extreme 802.11n Enabler for my MacBook Intel Core Duo. when i opened the disk image and tried to install, i got an alert saying my computer does not meet the hardware requirements - even though it is a MacBook Intel Core Duo.
i followed all instructions on the Apple Store page before purchasing, including checking my Network Utility to verify whether i needed the software. currently i only have the 802.11 a/b/g adapter. see:
http://store.apple.com/1-800-MY-APPLE/WebObjects/canadastore.woa/wa/RSLID?mco=B4 8E8262&nplm=D4141ZM%2FA
any suggestions? my MacBook is a week 25 model.
thanks,
gimiwan

Your computer needs to be a Core 2 Duo-based Mac for the enabler to install, as the necessary hardware isn't present on an older processor or a 1.83GHz 17-inch iMac. If your computer supports the enabler, install this software and try installing the enabler again.

So by the virtue of my MacBook being compliant with the 802.11d standard I am open to these issues? And from the way you are explaining it it sounds like Apple is ahead of the curve with implementing 802.11d compliance?
They're not ahead of the curve +per se+, but as an example many Windows XP machines are behind the curve if you will.
Would it be legal to write an app or driver that you can set ignore certain problem country codes when you want it to? Because something like this would help my issue also rather than playing lotto each time I turn my MacBook on or wake it from sleep, hoping it will see my wireless network first.
Unfortunately, I'm not a lawyer and not in Australia so I couldn't begin to guess at what is legal and what's not in this arena.
However, there is no interface to the driver to be able to manually set a country code, so the point may be moot.
I don't know what kisMAC can and cannot display, but the country code is broadcast within the 802.11 beacon frame and/or probe response frame if the frame's dot11MultiDomainCapabilityEnabled option is true, so you may want to try looking at its output of beacon frames.
Three octets make up the country code - the two character country code and a third octet which is one of:
    * An ASCII space character (0x20) if the regulations under which the 802.11 station is operating encompass all environments in the country.
    * An ASCII ‘O’ character (0x4F) if the regulations under which the 802.11 station is operating are for an outdoor environment only.
    * An ASCII ‘I’ character (0x49) if the regulations under which the 802.11 station is operating are for an indoor environment only.
The way the 802.11d standard specifies this all works is:
9.9.1 Operation upon entering a regulatory domain
A STA that is enabled for operation across regulatory domains shall default to passive scanning when it has lost connectivity with its ESS. Passive scanning is performed using only the receive capabilities of the station and is, thus, compatible with regulatory requirements. The timeout for determining the loss of connectivity is system dependent and beyond the scope of this standard.
When a STA enters a regulatory domain, it shall passively scan to learn at least one valid channel, i.e., a channel upon which it detects IEEE Std 802.11 frames. The Beacon frame contains information on the country code, the maximum allowable transmit power, and the channels to be used for the regulatory domain. Optionally, the Beacon frame may also include, on a periodic basis, the regulatory information that would be returned in a Probe Response frame. Once the STA has acquired the information so that it is able to meet the transmit requirements of the regulatory domain, it shall transmit a Probe Request to an AP to gain the additional regulatory domain information contained in the Probe Response frame, unless the information was previously received in a Beacon fame. The STA then has sufficient information available to configure its PHY for operation in the regulatory domain.

Note that this spec dates to 2001, so it's hardly something "new," just something that wasn't necessarily widely supported.
