Wireless N (802.11n) support removed from iOS 8.3?

Using an iPhone 6 plus here. My internet router is configured for two frequencies, 2.4Ghz and 5Ghz
After the ota update, my phone is no longer able to connect to the 5Ghz frequency.
Below are the wireless mode settings for each frequency (note : the settings below were working fine with iOS 8.2 and earlier)
When changing the mode to 802.11a for the 5ghz channel, I am able to connect. Did Apple disable wireless N mode on their devices?

My router (D-Link 825) works just fine with my iPads and my MacBook Pro both on the 5 GHz 802.11 band. Of course, if the router is working properly, there is nothing that one device can do to "kick other devices off." It is, after all, the router's job to manage communications between multiple devices.
So don't expect a fix from Apple. if your router doesn't work properly to manage communication between your iPad and other devices, get another router. Even wireless-N routers are pretty cheap these days. Also, many routers can be re-flashed with open source firmware freely available on the web.
I did encounter one odd problem when I first set up my iPad2, in that I was initially getting "unable to connect" alerts from the iPad2 when I tried to join my 5 GHz 802.11n network. I thought that maybe the iPad2 couldn't handle 5 GHz, so I turned on 2.4 GHz on the router and was then able to connect. But then I switched back to 5 GHz only mode, and the iPad2 re-connected just fine.

Can't connect to Time Capsule + no 802.11n support

I just got my new 13" MacBook (late 2008). Originally, I thought I couldn't connect to my wireless N router which happens to be Apple Time Machine. According to network utility program, my MacBook only supports a/b/g - this is not right! Now, I discover that in addition to the N problem I can't even connect to my Time Capsule wirelessly! Good thing I have 2 separate wireless routers (linksys).
My other Macs (white MacBook and 20" iMac) have no problem connecting to Time Capsule over 802.11n. Both machine indicates 802.11n support under network utility program.
Compound this problem with stuck 'a' key on my keyboard.
I really, don't get this problem. I spent an hour with Apple tech with no avail. I am thinking about returning this new MacBook.

I have the exact same problem you have described. Unable to find a solution. Odd because I have a 2007 MacBook Pro and it works fine wirelessly. Wireless-N on the MacBook works fine and it can connect to other wireless networks, just not it's home one.
If anybody is interested, here's a dump from the console log when airport attempts to connect. Our wireless station doesn't broadcast.

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.

How fast can Broadcom 802.11n support for maximum?

hey everybody,i got U160 yesterday that the WLAN adapter is Broadcom 802.11n but i just got a connection speed of 65Mbps but i can get 150 Mbps with my G230 with intel 5100 bgn ,connecting to the same N-Router,so i am wondering how fast can Broadcom 802.11n support for maximum.......

if readycomm installed, remove it.
check your firewall is active and using high performance.
by the way, which model of broadcom are you using?

No 802.11n support in macbook pro leopard install

I upgraded my MacBook Pro to Leopard last week (and then updated to 1.5.1 yesterday)
Other users here have claimed that they see 802.11n support in the Network utility (choosing en1 as the Network Interface). However, I do not. I only see a/b/g.
I also went ahead and purchased the 802.11n enabler (for $2.16). I got an error message that the software is incompatible with my hardware. My guess is that the enabler is probably incompatible with Leopard - although the Apple Store says nothing about this.
Why did others get 802.11n installed automatically via their Leopard upgrade but in my case it did not?
How do I upgrade my MacBook Pro (10.5.1) to 802.11n?
Thanks,
Bill

I just realized that I don't have the right mbpro for 802.11n as I don't have core 2 duo.
***** to be me I guess.
I'll look for an after market solution to upgrade to 802.11n.
Thanks.

Extreme 802.11n support for POE 802.3af?

Can anyone confirm if the new (current) generation Airport Extreme 802.11n supports PoE installation? There was a special -- also called education -- version of the previous generation Extreme based station for POE installation.
thanks.
* Nevermind, found previous posts!

jheiliger, Welcome to the discussion area!
The new square 802.11b/g/n AirPort Extreme base station (AEBS) apparently does NOT support POE (Power over Ethernet).

Why doesn't the AEBS 802.11n support NTFS?

I am wondering why users need to go through hoops to make the $200 AEBS 802.11n recognize NTFS formatted disks. Is it really that complicated for Apple engineers to add this support? Is there any way to reach Apple tech and request this? Or is asking for NTFS support utterly ludicrous and fundamentally not feasible. If it is futile to hope for Apple to add support for NTFS to the AEBS 802.11n, then how does one go about returning - who to contact to return and get the money refunded.

Was "Wi-fi Cellular" removed from iOS 6?

I read a lot about an iOS creature that would use cellular data if a wi-fi connection degraded (or the device had a strong wi-fi connection but lost Internet access, etc.). The setting was supposed to be found under Settings -> General -> Cellular. Tonight, however, after upgrading my iPhone 4S to iOS 6, that setting is nowhere to be found. Was it removed from the iOS 6.0 release?

I was looking for the same thing and can't seem to find it either...

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...
http://discussions.apple.com/thread.jspa?messageID=3989864&#3989864
and this site mentioned...
http://www.macintouch.com/reviews/airportn/#performance
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.

802.11n support ... 2.4 or 5 GHz?

Which printers have support for 802.11n on the 5 GHz band, rather than the (more common, but prone to interference) 2.4GHz band?
This question was solved.

No HP printers support 5GHz that I know of.

How to keep photos in folders when removing from iOS?

I usually use Preview on Mac to import photos and delete them from the iPad. I've started putting photos in folders but this organization is not maintained on import. Is there a way to maintain this when importing? Or even better: is there a way to leave certain folders on the iPad and import/delete the rest?
Of the photos that have been imported, is the folder data maintained somewhere so I can reorganize them? Maybe I need to find a better method of importing & deleting.

iPhoto, Image Capture, Aperture...but I have never heard of using Preview to import photos to the Mac.
Folders/albums that you create in the Photos App on the iPad are for local organization on the device itself and will not import to your Mac. These folders/albums do not contain copies of the photos, but merely use pointers to the photos to make the pictures appear in these local albums. If you create new albums in the photos app and try to remove the photos from the camera roll, they will be removed from the folders as well.

[SOLVED] ssh-agent support removed from kde-agent

Hi all,
Since its upgrade yesterday, kde-agent does not support ssh-agent anymore (see here). I consequently can't store unlocked SSH keys anymore, because ssh-add from a konsole can't connect to ssh-agent.
The update note above mentions that the SSH agent is not needed by KDE since years. What's the recommended way to start it now ?
Thanks a lot !
Aurélien.

I have been using ssh-agent with KDE on a daily basis for years and AFAIK, there is no better or more convenient way of keeping your private keys available. So in my opinion, the removal of ssh-agent, a tiny daemon that doesn't do any harm yet serves its purpose very well, was a bad idea.
I found a solution that does not run multiple ssh-agent daemons, even if KDE crashes. The solution is based on the fact that ssh-agent can be used as a wrapper around a session startup script or program. Unfortunately, my solution is very intrusive and will disappear on each KDE update. It works as follows:
# cd /usr/bin
# mv startkde startkde-inner
# cat > startkde <<- HERE
#!/bin/sh
exec /usr/bin/ssh-agent /usr/bin/startkde-inner
HERE
# chmod +x startkde
Now the ssh-agent will be started on each KDE session and there will always be only one ssh-agent per KDE session. Comments in the startkde script suggest starting ssh-agent later in the process and then killing it on logout. However, such a solution is inherently unreliable, because it will not kill your ssh-agent when the X-server or KDE crashes. The same problem applies to starting ssh-agent from profile scripts. The wrapper method resolves the issue in a quite reasonable way.

AirPlay Supported Directly from iOS to AirPort Express?

Does AirPlay support audio streaming directly from an iOS device (iPhone 4 specifically) to AirPort Express-powered speakers?

Yes it does. My speakers on my desk are hooked up to an Airport Express so that I can get up & move my laptop around & the music can stay pumping out of the same speakers.
This is supported in iOS 4.2. It's great. It even turns down the music when a call comes in, because you're technically listening to your iPod. Nice Touch.
I wonder if I'll ever even boot up my computer again!
There are new Text Message Sounds too!
& the volume bar in the multitasking bar (2 slides to the left [as seen on iPad screenshots]) is a great feature too!
Loving this update so far.
(after the initial scare of calendar items & music missing - but they were fine after another sync).

WAP4410N and WRT610N Cant Bridge Wirelessly in 802.11N

I have two buildings across the street from each other and purchased the WAP4410N on advice of a tech support rep at Cisco who stated I would be able to bridge the two locations with the WAP4410N and my current router WRT610N in N mode however todate 8 month later I've gotten no success in bridging in N but I've been successful in G, but the connection is spotty (not to mention VERY SLOW) as it's just out on the verge of being out of range. for the four tech's who've opened cases they agree this is possible but have been unable to get this to work in their lab or onsite here and close the case after they give up since there is at least A bridge irregardless of how poor of a job it's doing.
Has anyone been able to bridge in N mode? If so any advice as to the specific settings you have been able to use to connect? If not, or you can verify why not, what additional changes I will need to make.
and yes I am aware that running a line would be a better option, but it would be $3k to have the pipe just across the street let alone the burial quality cat5 costs

A reasonable solution would be not use the wrt610n and get a wrvs4400n version 2. Your connecting up a consumer product up to a small business product and in the past i have seen issues with stable and reliable connections. The wap4410n and the Wrvs4400n have what is called WDS that they can use to make the bridge connect up and be more stable for you. It would be a less expensive option than burying a line.

Was Greek Autocorrect removed from iOS 8?!

Hi everybody,
I just updated my iPhone 5 to iOS 8 and noticed that the autocorrect for greek seems to be gone!
I have the option to enable "correction" but for English only.

Found it! It was not removed... Just wasn't enabled... Sorry about that...
