What may interfere with 802.11n?

Hello!
I've got a very strange problem with my MacBook.
I've just bought a new TC to replace my old 802.11g wireless access point.
Now, there is a very strange thing: 802.11n has a very good signal in all my house, except my room. In the corridor, the signal is excellent (100% or so), but when I walk 1 meter inside my room, the signal disappears almost completely (and it isn't possible to surf the Net).
What may cause this? It's very strange...
Also, my iPhone, which uses 802.11g, can connect in my room, and so was I able to do with my old router... So it seems only a problem of n-wireless...

and so? what shall I do?
I cannot disable n wirelessing so my MB always tries to connect using n...
then, in every other room it's working perfectly... for istance, at the moment I'm in the kitchen and I'm surfing wirelessly...

Data and Voice separation with 802.11n

Hi there
I'm interessting in some design guides. I would deploy data in 2.4 GHz band and the voice in 5 GHz band. But aren't there problems with the 802.11n deployment, I thought that this works better in 5 GHz.
What recommendations would you make and did you have some issues with this design?
Thanks in advance.
Dominic

Hi Dominic,
You can find all kinds of documentation on Cisco's 802.11n homepage: http://www.cisco.com/en/US/netsol/ns767/networking_solutions_package.html
To answer your questions, there is no "problem" with running 802.11n in the 2.4GHz space, but there are limitations. You cannot use channel-bonding, which is the primary source of the added bandwidth that 802.11n offers. If you want to see 150Mbps data rates, you'll need to deploy it in a 5GHz implementation.
Another advantage to running in 5GHz is that you can isolate your 802.11n traffic from your 802.11b/g traffic on the 2.4GHz radio. This will prevent slowdown that can occur when legacy clients coexist with 802.11n clients.
So yes, you're correct to say that it does work better in 5GHz. The nice thing is that most 802.11n chips in laptops support this band.
That said, it would be best if voice and data can both exist in the 5GHz space. You can accomplish this by creating different SSIDs for your voice and data networks. There is nothing wrong with deploying both in 5GHz.
Let me know if you have anymore questions. Thanks!

Cant load the airport express with 802.11n

today i just got my new airport express with draft n. but my router can't load the config anymore after i uploading my setting ( change to N with 5 GB ). i've tried all of methods that the manual included. I think i need to exchange the new one. i just bought it yesterday.

I am being prompted to update Firefox, but upon consulting the details, I find that it may interfere with my Windows XP. How can I stop the prompts?

I am still using (and will not be updating) Windows XP. The details of a Firefox update indicate that the new version (which I don't need) may interfere with XP. I want to have Firefox cease and desist prompting me for an update. How can I do this? I just keep selecting "Ask me later". Is there a more permanent fix?

Firefox 32.0.3 works fine on WinXP and contains many important security patches - in fact the "nightly" Firefox 35 pre-release tester version works fine, too.

Apple AirPort Express Base Station with 802.11n - MB321LL/A. How to set it up to my new iMac

Community:
How do you set up an
Apple AirPort Express Base Station with 802.11n - MB321LL/A how do you set up on Mac running on OS X 10.9.4?
Please advise
Fmsalazar

Apple did say it was important.
If the units do not show up in the airport utility then you must set it correctly to link-local.
Steps for OS X Lion or Mountain Lion
This can happen if IPv6 has been disabled. To enable IPv6 for your network interface:
Choose Apple menu () > System Preferences, and then click Network.
If a lock icon appears in the lower-left corner, click it and enter your admin name and password to unlock the pane.
Click your network service (Wi-Fi or Ethernet) in the list, and then click Advanced.
Click the TCP/IP tab.
Choose Link-local only from the Configure IPv6 pop-up menu.
Click OK.
Click Apply.
AirPort base station not seen or "An unexpected error occurred" appears in AirPort Utility 6.3
Apple rep says the same.
Re: Unexpected error when connecting Airport Express A1264 to Airport Utility 6.3.1
I am searching as I saw it in a thread today where a person had issues. (No contribution from me in the thread but found that was the issue).
It is kind of a fail safe.. since auto can end up with any setting.. and it will depend on the setting of ipv6 in the Airport Router if it works properly in the computer.. setting it to the correct value is one step in sorting out problems when people get in a mess.

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-
Charles offers good advice-you need a router.

Connections dropped, DNS and server timeouts from new Lenovo with 802.11n

New Airport Extreme, works great with Windows XP machine ethernetted into it, and also with a MacBook with wireless-N.
But my brand new Lenovo T60P with wireless-N is flakey with the Airport. It connects fine with a 100% signal, using the WPA2-PSK / AES setting on the Lenovo (WPA2 Personal security in 802.11n b/g compatibility mode on the Airport). Most of the time it works quite well.
But very frequently (every five minutes?) one of two things will happen: with the signal still registering fine in the taskbar (and in the laptop's wireless "status" utility), it will become unable to locate any website, including google.com, etc., and refreshes of currently-displayed websites yield server timeouts. The browser (firefox) gives a DNS timeout message. The second thing is just your basic dropped wireless connection. It will reconnect by itself after a while.
Any advice is hugely appreciated. It ***** to "upgrade" to headaches! (Ha! the forum software doesn't like a synonym for "vaccuums". Apologies to the nuns at Apple for my potty mouth.)

What you experienced is not a surprise as 802.11n is not a standard yet and each manufacturer has developed it own "pre-n" version. Right now Apple (base station) will work with Apple (notebooks), Dlink (routers) will work with Dlink (PCMCIA cards), etc.
Lenovo is no different. You can expect 80-90% compatibility, but not 100%. To expect cross-vendor 100% compatibility, you will likely have to wait until 802.11n is "approved" and then the firmware is updated on all devices.

What may interfere in updating my apple tv?

my apple tv support just expired and i cannot get it to update. what may i do to trouble shut it?

Welcome to the Apple Community.
If you are using ethernet, try the update with wifi.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router.
Reset the Apple TV (Settings > General > Reset > Reset all settings)
Restore the Apple TV (Settings > General > Reset > Restore)

Will older macs ever work with 802.11n

Just wondering if the requirements for 11n is just a matter of buying a new network card or does the hardware also have to support it as well. I ask only because I have a G4 & G5 on my existing airport network. Have a MacBook Pro also on network. I would like all of them to be at the same speed if possible.
multiple macs Mac OS X (10.4.8)

retouch4food, Welcome to the discussion area!
As you undoubtedly know from reading the "Help & Terms of Use" for this area, we are all Mac users like yourself. Therefore we have no special knowledge of future Apple plans or products. Also the discussion of future plans and products is forbidden in this discussion area.
But... based on past history... it is very doubtful that you will see any type of 802.11n upgrade for existing non-802.11n Macs. 802.11n depends on multiple antennas to perform it's magic and it would be very difficult to change built-in antennas in the existing Macs.
With all that said... if you want to give your non-802.11n capable Mac 802.11n access, the best solution will probably be an Ethernet 802.11n adapter.

PC laptop card to work with 802.11n?

I'm thinking of getting the new Extreme for my wife's Late 2006 Macbook Pro, but her sister is often on the same network with her PC laptop, an Acer Aspire 5100-5022 on which the current card is only g/b. Anyone know @ how much for an upgraded card for that, and any specific recommendations?
Thanks

I will give it a try for a second time with the installation method they suggest at Amazon. It works ok with Airport but it has a lot of issues with speed. I was with a technician at Linksys and after going through all my settings, they asked me to try with another computer. I am in the process to buy a new laptop and try it there to see where the problem lies. (he he he)
I will post an update when I try the new installation.
By the way the older adapters 802.11N can reach the 300 Mbps if the router is set in the 5Gzh/40Mhz radio band.
Many thanks for your comment and the link.

First time working with 802.11n, not working properly?

Hello,
This is the first time I use 802.11n in my network there is only one AP1141 but the clients don't connect at 802.11n rates, instead they connect at data rates as low as 11 Mbps. At the begining they connect at 144 Mbps but immidiatly it decreases to 11 or 12.
Many of our wireless clients in the company are Intel(R) WiFi Link 5100 AGN.
Any comments?
AIR-AP1141N-A-K9
AIR-WLC2106-K9
6.0.182.0
Let me know if more info needed?
Thanks

Hi George,
So you suggest to keep only WPA2/AES?
Regarding the coverage area keep in mind this is a really small 4 floor building with an AP floor floor, I installed only one AP1141 in my floor and kept the AP1131 in the other 3 floors, I might reduce the power to half since I don't need them working at full power unless I need coverage in the stairs in order to enforce roaming to IPPhones. Also, I don't want to bond channels on 2.4 because I read that as a recomendation in a Cisco's document (anyways I did not find how to do it in 2.4, wuld be a nice tip if you tell me how just in case) so 144 Mbps would be great as long as it works properly. I did not experienced these rate hoping until I enabled this AP1141.
And yes most of the clients that reported issues are Intel (engineering team, haven't checked the rest yet).
Regards!

Do my Airport Express just buy are with 802.11n?

I using imac 2.4 GHz model 2008 which understand that it build in with airport extream 802.11n standard, isn't it?
Also just buy Airport express but doubt that this AX is on which 802.11n or not?
Because it shown only 802.11 a/b/g.
And since I found software for airport 802.11n available for 1.99 US$, Do I need to install this software to be able to run 802.11n?
Thank in advance.

No, special software isn't needed. You have AirPort Utility already installed on your iMac and it is located under Applications/Utilities. Run AirPort Utility and go to Wireless and make sure you have an 802.11n mode selected (whether it is 802.11n only or 802.11n with b/g compatibility enabled).

Major Problems with 802.11n Upgrade:-(

Since I installed the new 802.11n update, my upload speed is virtually unusable: it stays at or below 10-11k.
I am connecting a Mac Book C2D to a D-Link 655, and everything worked great until I applied the update.
I've reinstalled several times, to no avail. Any ideas?
How do I uninstall the 802.11n Update?

this is why they call the N specification a "draft."
it's beta. uncompleted. devices from different manufacturers cannot be guaranteed to work at all until everyone's using the final spec.
i would NOT RECOMMEND following the advice on macfixit.com to replace parts of your airport driver with older versions. instability will result in a system with mixed software versions when apple's software updates are installed.
at the very least... when 10.4.9 is released, USE THE COMBO UPDATER, not the delta. it will write over the version discrepancy you created, allowing you to "re-apply" your hack if you're still experiencing trouble.

Range with 802.11n patch

I've heard that the 802.11n will increase the range of standard g/b networks, not that much, but a good amount. Is this true?? Is it worth upgrading with the patch if you only have regular wireless??
Thanks

Absolute rubbish, the patch will not affect b/g in anyway whatsoever.

Wireless Connectivity Issue with 802.11n.

We have a 5508 Controller and sixteen 1142 APs.
Several of our laptops were experiencing connectivity issues over Wireless. Older laptops that do not support 11n are not having any problems.
I disabled 802.11n for both 'a' and 'b/g' in the Controller. Now the newer laptops connect with no issues.
They would in fact connect to the APs while 11n was available, just no Internet Access - (cannot ping DG, etc). Disabling/Enabling the laptop WL adapter would allow brief access (sometimes), but they'd quickly lose Internet Access once again.
Our WLANs are configured for WPA2/AES.
This looks like a 802.11n configuration issue at either the Controller or the Laptops (or both). Both are using the Default settings for 801.11n.
Any recommendations for correcting this? Are there best practice guidelines for configuring 802.11n?
Thanks.
