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.

ASK THE EXPERTS - Update on 802.11n with Fred Niehaus

Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to get an update on 802.11n with Cisco expert Fred Niehaus. Fred is a Technical Marketing Engineer for the Wireless Networking Business Unit at Cisco, where he is responsible for developing and marketing enterprise wireless solutions using Cisco Aironet and Airespace wireless LAN products. In addition to his participation in major deployments, Fred has served as technical editor for several Cisco Press books including the "Cisco 802.11 Wireless Networking Reference Guide" and "The Business Case for Enterprise-Class Wireless LANs." Prior to joining Cisco with the acquisition of Aironet, Fred was a support engineer for Telxon Corporation, supporting some of the very first wireless implementations for major corporate customers. Fred has been in the data communications and networking industry for more than 20 years and holds a Radio Amateur (Ham) License "N8CPI."

Fred might not be able to answer each question due to the volume expected during this event. Remember that you can continue the conversation on the Other Mobility Subjects discussion forum shortly after the event. This event lasts through March 25, 2011. Visit this forum often to view responses to your questions and the questions of other community members.

So there are two parts of this question, the latter part I cannot address as it is a future question. Cisco does not comment on products that have not been released or on the strategy of next generation products.
That said, Cisco was first to market with an 802.11n Access Point and well (we didn't all go on vacation after we did that)
So let's talk a little about spatial streams in general and how it relates to what customers are doing today.
The Cisco 1040, 1140, 1250, 1260 and 3500 Series Access Points are all two spatial streams (2SS).
As of the time of this writing, a critical mass of 3SS and 4SS compatible clients have yet to be deployed, and the vast majority of WiFi clients that will be deployed over the next 18 months will be 1SS and 2SS clients.
The higher SS clients are likely only show up in some higher end notebooks -- Why? well it is a given that smartphones and tablets are likely to continue to be 1SS and in some rare cases 2SS.
This is because additional radios used in this technology consume battery life, add to the physical size of the device and increase the cost. Also many devices leverage the same single antenna for cellular as well as WiFi. Therefore, it is my opinion that 3SS Access Points provide little if any performance benefit for smartphones or tablets in the enterprise today, and any real throughput gain is likely to occur with high end notebooks in close proximity to the Access Point and those are rolling out very slowly and we are monitoring this.
Now we get to my favorite part of this.. I get to ask myself a question and then answer it..
So Fred are you saying that there is no value in 3SS and 4SS?
Of course not, 3SS performs similar to 2SS beyond a short distance, and with any multi-SS product RF interference must be addressed to capture the performance benefits of higher SS Access Points. Actual throughput in any WiFi environment is highly dependent on the presence of interferers and obstacles.
Without the ability to mitigate the impact of interference, 3SS solutions will "downshift" to 2SS of 1SS and lose all the performance benefits anyway IMHO.
I don't want to sound like a commercial, but you really do need Cisco cleanair technology in the AP and Cisco innovations deliver more and will go beyond the simple 3SS aspects of the 802.11n standard.
IMHO it's more about CleanAir, good RF system design, and what we put into the AP with regard to performance "in the environment" and not what is on some spec sheet today.

802.11n with Bootcamp and Windows xp

My 13 inch Macbook connects to my airport network at 802.11n 5GHz dual bandwidth using OSX but only 802.11g works when using bootcamp and windows. My 802.11n network shows-up on windows as an available network and I can type in my network password but it won't make the connection. Is 802.11n automatically active with bootcamp? I am able to connect at 802.11n speeds to my network using my work's Window laptop and a Linksys 802.11n usb card so I know it works.

Airport Extreme 802.11n with Nortel VPN client

Hello,
Has anyone had any experience using the Airport Extreme 802.11n) with a PC (sorry, I have both a PC and a Mac)running the Nortel VPN client?
The new router works perfectly with the Mac but I also need to use the VPN on the PC for certain functions in my work. On my previous router (Dlink DIR625), I had to set a dedicated virtual tunnel to port 9550 to solve this issue. I think this might still be true for the Airport Extreme but I don't see how to do it. Any help would be appreciated. Thanks.

I had the same problem and an apple apple care tech walked me through it yeterday.
Call them, they were great.

Numerous problems with Airport Express 802.11n with DSL and extending WLAN

Hi all,
I have the following hardware:
802.11b/g Airport Express with firmware 6.3
802.11n Airport Express with firmware 7.3.2
MacBook Pro
iBook G4
Mac Pro PowerMac 2x450 G4
Up until now I had been using the old Airport Express as the base station connecting to my PPPoE DSL line, and it worked fine. I wanted to extend the range of this network, and got another newer Airport Express, the 802.11n model.
First I tried to use the 802.11n to connect to the Internet and the old one to extend the network. Turns out the old one can't be used to extend a network, which is bad enough, but the 802.11n one refuses to connect via DSL for more than a couple minutes, then drops the Internet connection.
So I tried downgrading the firmware to 7.3.0 and 7.3.1, but it didn't help. Did a hard reset, factory default reset, soft reset, nothing worked.
Next I tried swapping the two, putting the old Express back on the DSL line and the new one as the bridge to extend the network (using WPA2). But the 802.11n complains that it can't access the network and flashes amber.
Again, tried upgrading to 7.3.2, downgrading to 7.3.1 and 7.3.0, hard reset, soft reset. Nothing works.
Any ideas?
Cheers,
Fairfax71

I don't see any option in the Airport Admin Utility for the old Express for creating a WDS network, only to participate in one...?
That is the option you want to choose.
You could use the newer AirPort Utility to configure the older AX.
Sorry, forgot to ask something else: The 802.11n Express is able to join the WLAN created by the 802.11b/g Express as a client, but not extend it, is that what you're saying?
No. If you join the network the AX is simply acting as another wireless client and is not extending the network. The "extend" option is not available since the older AX is not 802.11n capable. You must use WDS.
Use AirPort Utiity and follow these steps for both AX's. To set up the main AX:
Click the AirPort status menu in the menu bar and choose the wireless network created by the base station you want to set up as the main base station.
Open AirPort Utility (located in the Utilities folder in the Applications folder on a Mac, or in Start > All Programs > AirPort on a Windows computer). Select the main base station, and choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary. If the base station is using the default password of public, you will not be prompted for a password.
Click the Wireless button, and then choose “Participate in a WDS network” from the Wireless Mode pop-up menu.
Click WDS and then choose “WDS main” from the WDS Mode pop-up menu.
Select the “Allow wireless clients” checkbox if you want client computers to connect to this base station.
Click the Add button and enter the MAC address of the base stations you want to connect to this base station. If there is a base station listed that you’d like to remove from the list, select the base station and click the Delete (–) button.
Click Update to send the new settings to the base stations in the WDS. By default, the “Allow wireless clients” checkbox is selected. If you deselect the checkbox, and later want to change the settings on the base station, you must connect to the base station’s LAN port with an Ethernet cable. You will not be able to connect to the base station wirelessly.
To set up the second AX to connect to the main AX:
Open AirPort Utility. Select the AX, and choose Manual Setup from the Base Station menu. Enter the base station password, if necessary. If the base station is using the default password of public, you will not be prompted for a password.
Enter the same network password as the main base station, if necessary.
Click the AirPort button, and then click Wireless. Choose “Participate in a WDS network” from the Wireless Mode pop-up menu, and choose the same channel as the main base station from the Channel pop-up menu.
Click WDS and choose “WDS remote” from the pop-up menu.
Enter the MAC address of the main base station in the WDS Main field. The MAC address is also referred to as the AirPort ID and is printed on the label on the bottom of the base station.
Click Update to transfer the settings to the base station.

Cannot Connect Airport Express 802.11n to WEP 64 Bit Wireless Network

I am currently use a Netgear MR814 who's only built in security is WEP 64bit.
I am attempting to connect my Airport Express 802.11n to it and I see the WEP 40 bit option and use that and it puts in my password for the wireless as 0xPASSWORD.
However it is unable to connect to the network. I scoured these forums and attempted the "$" escape character and the "" option by none of these work.
Is there a way for me to configure my AE to be able to connect to my (older) wiresless router?

I found information indicating that this airport express must be set up by airport utility 5.6.1, but that version is not supported by Lion.
AirPort Utility 5.6.1 is not supported by Lion....it was designed for Snow Leopard.
You need the correct version of AirPort Utility 5.6 for Mac OS X Lion
Give the correct version a try and then please report on your results.

Using Airport Extreme (802.11n) with Netgear Wireless Modem Router

I have a quick question, can I use the Airport Extreme in a wireless modem router?(http://www.netgear.co.uk/wirelessadslrouterdg834g.php)
By plugging the Airport into the Netgear router would I be able to by pass and run a network this way. I have a 802.11n enabled MacBook and Apple TV, the Netgear is the weakest link!!!
Many thanks.

neptune2000's post was implying that you connect the AirPort Extreme base station (AEBS) to the Netgear.
The AEBS does NOT contain a modem. Therefore you will need a modem, either the Netgear or another.

Connecting Nintendo Wii - 802.11n AEBS - Broadband Router aint worken?

Hey guys, Ive just bought a new Nintendo Wii which is working a charm, but i cant seam to be able to get it to connect to my wireless network, (my new iPod Touch is also having the same problems (works fine on all networks other than home).
Essentially I've got my broadband modem plugged into a router upstairs and my AirPort Extreme (802.11n) plugged into the aforementioned router upstairs (for some reason AirPort Extreme wouldn't recognize plugging the broadband router straight in rather than through another router) so my setup is:
Broadband Modem -> Wired Router -> AirPort Wireless -> Wii
I think the fact that i have my internet connection coming from another router (whose settings i cant change cause I've forgotten the routers password) and then plugged into my AirPort is whats causing all my troubles??? So ideally if anyones got any suggestions why my AirPort wont accept direct connection from my broadband router i think that might do the trick but making my current setup work for the Wii would be cool.
This is really causing me allot of troubles with heaps of devices so any help is welcome!
Thanks in advance!

Hello kungfuelmosan. Welcome to the Apple Discussions!
I suggest that you try connecting the 802.11n AirPort Extreme Base Station (AEBSn) directly to the broadband modem again, but this time make sure to allow enough time for a complete power recycle of the network components when doing so as follows ...
Try the following, in order, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AEBSn, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Unable to connect to AE 802.11n through airport utility -despite resetting

Hi all,
I do realize that there are a number of threads adressing what seems to be my problem, but none of the solutions have worked for me.
I have a 2 year old AE 802.11n that has given me flawless wireless network for a long time now. I have for some time been unable to connect to it and change settings through the Airport utility, for example I was unable to update to the 7.4.1 firmware, so I am (was) running 7.3.2.
Today I wanted to setup a external hard drive connected to the aiport, so I needed the Airport utiltiy. After numerous tries, including a direct connection through an ethernet cable, I was still unable to connect. I was getting the infamous 'Make sure your Apple wireless device is plugged in and in range of your computer or connected via Ethernet and try again. (-6728)' error message, despite being able to detect the base fine.
It seemed that resetting the airport had helped a lot of other people, but Alas!! I used soft reset, hard reset and factory reset (presseing the reset button while plugging in the power), and still no luck. The only change is that now my network is no longer working (not surprising), and the base name has changed to factory default. What puzzles me is that Aiport utility states that the base is running the 7.3.2 firmware, while I am certain that it came with version 5.something as factory default. I have just left it without power for a few hours, and still the same.
So, how do I connect to my beloved AE again?
Thanks!
Oh, and I have the same problem on my 3 year old iMac and my brand new MacBook Pro....
Nikolaj 'getting desperate' HTP

I found a workaround:
I removed my new (5.4.1) version of Airport utility, and re installed 5.3.2 (downloaded here: http://www.apple.com/downloads/macosx/apple/application_updates/airportutility53 2forleopard.html)
I could then access the Base, setup my AirDisk, update the firmware, and AFTER the firmware update, reinstall Airport utility 5.4.1. It seems that everything is working now.

Airport Extreme 802.11n (with gigabit ports) locks up when using 802.11g

About a minute after I connect my 802.11g IBM X60 laptop to the wireless network, the AirPort Extreme with 7.2.1 firmware locks up. The light stays green, but all machines (including an 802.11n MacBook) loose wireless connectivity. It's extremely annoying and makes the base station unusable. I have to physically disconnect it from the wall and plug it back in for it to work again.
Has anyone found a fix for this?
It works fine when a single 802.11n Macbook is connected.

Changing it to 5Mhz didn't help. I unplugged my external HD from the router. Want to try to figure out what made it start locking up because it didn't do it when I got it two weeks ago, just started yesterday.
But I might be going to a mall where an apple store is, might just have them swap it out. It's hard to prove this type of thing, unless it's a known problem and they take your word for it.

Having problems connecting to wireless network when extended

Hi. I recently switched over to a mac and love it!! However I recently purchased a Time Capsule and a Airport Extreme to extend the network and am having problems. My macbook continues to log onto the guest network and not the main wireless network. When I try to switch to the main network it asks me for the WPA password and then it tries to connect but then states connection timeout. When I remove the guest network from my list of networks it will not allow me to connect to the internet at all through the main wireless network unless I power down the airport extreme that is extending the network. One final note, I have no problems at all if I keep the airport extreme shut down and do not extend the network. It seems it is not the time capsule but the airport extreme. One other additional note, my windows machines are having no problem connecting to the main wireless network with the network extended!!

Welcome to the discussions!
A few thoughts:
If you have not already done so, it will makes things easier to troubleshoot if you assign separate names to your "main" and "guest" network. By default, they are the same name and it sometimes is difficult to know what network you are actually connected to.
Open AirPort Utility, click Manual Setup
Click the Wireless tab below the row of icons
Look for an "options" button. This should allow you to assign a separate name for the "guest" network.
The "main" network can be extended, but the "guest" network cannot be extended. Your other computers may be connecting to the "guest" network unless they are newer devices capable of connecting at 802.11n only 5 GHz.
It's easy to make a mistake when setting up the "extend" feature. Please check the following settings for your TC and AirPort AX or AEBS (You posted in the Airport Express forum, but talk about having an AirPort Extreme in your post).
You will use AirPort Utility - Manual Setup as above to check your settings as follows:
_On the Time Capsule:_
Click the Wireless tab below the row of icons
Wireless Mode should be "Create a wireless network"
Make sure there is a check mark next to "Allow this network to be extended"
_On the AX or AEBS:_
Click the Wireless tab below the row of icons
Wireless Mode should be set to "Extend a wireless network"
Make sure there is a check mark next to "Allow wireless clients"
The Security and Password settings must match the settings of the TC exactly
You should now be able to identify whether your computers are connecting to the "main" or "guest" network. If your computers are connecting to the "guest" network, they are connecting directly to the Time Capsule regardless of their location in relation to your device that is extending the network.
Using your Mac, if you hold down the "option" key while you click on the fan shaped airport icon at the top of the screen, you will be able to see whether you are connected to the "main" network (802.11n 5 GHz) or the "guest" network" (802.11 2.4 GHz).
The BSSID will display the AirPort ID of the device that you are connected to. By noting the ID of your Time Capsule and AX or AEBS, you will know which device you are actually connected to on the network. As you move closer to the "extending" device, your computer should automatically switch to the device with the strongest signal.
Please post back on your findings.

Connecting AirPort Extreme 802.11n directly to my Verizon FiOS service

I want to connect my new AirPort Extreme 802.11n directly to my Verizon FiOS service. The ActionTec wireless router supplied by Verizon died, and I bought an AirPort Extreme as a replacement. When I configured the AirPort extreme, it would not connect to the internet. I have read some posts here that indicate I plug my AirPort Extreme into the ActionTec and I am OK, however the ActionTec is dead.
Are there settings for the AirPort Extreme that are unique for going straight to the internet? What am I missing? My FiOS connection is an Ethernet connection- not coax.
Here is the interesting thing- I have an old AirPort Extreme (the round cone shaped model) that I plugged into the Verizon FiOS Ethernet connection. Everything works fine- I have a wireless connection to the internet. I didn't set anything. So my assumption is that I can make the new AirPort Extreme work with the Verizon FiOS.
Any help will be greatly appreciated, as I do not know if I have the strength to go through the Verizon help desk.

Good news! My problem was solved by calling Verizon FiOS support. The service tech said an AEBS can connect straight to the FiOS Ethernet connection. He broke the "lease" on my connection, had me connect the cable from the wall to my WAN slot, and then he "leased" my network connection to my AEBS. Works like butter now.
He said that the Verizon FiOS network "leases" the network connections every 24 hours or so, and had I left my AEBS connected to the network, it would have pushed the new setting down to the AEBS.
Thanks for all of the input.

USB 2 HD connected to AirMac 802.11n station

Since I got my AirMac 802.11n base station I had my external HD connected to it and felt it was sort of slow that way.
Today, when I had to copy like 20,000 files over I was getting frustrated and unmounted it wirelessly and connected it directly to the USB 2 port on my MBP.
As suspected, the direct connect transfer speed is approximately 1 jillion times as fast.
So unless you have multiple computers and absolutely need to mount your HD wirelessly I strongly recommend directly connecting it.
doug

This is quite normal. Since you're using a wireless interface, you'll probably get 1/5 the speed as a direct connection with USB.
My setup with a USB disk gets about 80-130mbs wirelessly vs. 350-380 through a direct USB connection.
For bulk file operations, video conversions and backups, I connect directly to the USB. If I'm watching videos or editing files wirelessly through an Airport Disk, it's always on the Airport Extreme.
I guess what I'm saying is that you're right and that what you're seeing is normal.
Best of luck!

TC connects to PC (802.11n) DHCP IP assigned but no DNS lookups

Replaced my Linksys with a Time Capsule. Our iMac works fine. Our MBP works fine.
Just recently our room mates PC is not resolving domain names. Her 802.11n USB wireless connection had been working fine. But now when she connects she is assigned an address via DHCP and her DNS is registered as the TC ( as is ours in Mac land). But her PC is unable to resolve any DNS names.
I hard coded the DNS server of our ISP in her windows configuration and this work-around is working for her. But I would like to understand what went awry.
Ideas?
Warren

One thing I forgot to add. The TC assigns it's own address (10.0.1.1) to Mac's and PC's alike. But in the case of the PC is in unable to resolve domain names...
