5800 automatically looking for Wireless networks p...

my 5800 keeps popping up annoying notifications of "wireless network found" whenever i'm in an area that has a wireless network.
i dont want this.
i have DISABLED wireless scanning.
in settings, "show WLAN availability" is set to "NEVER"
and yet i keep getting these annoying notifications like every 5 minutes! sometimes the problem totally stops on its own. at other times the notifications keep popping up like crazy despite cancelling them repeatedly.

Check settings of apps that need a connection like e-mail, Facebook, etc....

The password for wireless network was changed. Airport keeps trying to sign in automatically with old password and won't let me put in new password. Any ideas?

You really should change both the wireless network name and password to avoid potential conflicts with the old and new settings.
Suggest you give that a try.

Stuck interrupt when scanning for wireless networks (Athero chipset)

I'm working on getting wireless running on my Thinkpad T40 with an Atheros AR5211 a/b adapter. The ath5k module loads automatically, and the dmesg output seems to indicate that it is properly detecting the card:
% dmesg|grep ath
[ 4.767272] ath5k 0000:02:02.0: registered as 'phy0'
[ 5.042780] ath: EEPROM regdomain: 0x61
[ 5.042787] ath: EEPROM indicates we should expect a direct regpair map
[ 5.042793] ath: Country alpha2 being used: 00
[ 5.042796] ath: Regpair used: 0x61
[ 5.478542] ath5k: phy0: Atheros AR5211 chip found (MAC: 0x42, PHY: 0x30)

[ 5.478553] ath5k: phy0: RF2111 2GHz radio found (0x23)
I brought the interface up using ip:
% ip link show wlan0
4: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether [redacted] brd ff:ff:ff:ff:ff:ff
The trouble comes when I try to scan for wireless networks. I run "sudo iw dev wlan0 scan". At this point, the system becomes very sluggish, and the load average began to monotonically increase. The scan never completes; I left it for 15-20 minutes and cut it off when the load passed 3.5. The load average did not go down after iw was killed. Checking in top, the CPU was pretty evenly split between a kworker process and ksoftirqd, even with the scan terminated.
I've searched around, and while there are all manner of problems reported with getting various wireless configurations to work, no one seems to get tripped up at the scanning phase like this. Does anyone know of diagnostics I could try (or perhaps other scan tools?) to narrow down what is actually causing the CPU to get hammered?

I got a chance to play around with this a bit more, trying wireless_tools this time:
% sudo iwlist wlan0 scan
wlan0 Failed to read scan data : Resource temporarily unavailable
As before, the load average then continues to increase until the system becomes unusable. This would lead me to believe that I have a driver or kernel issue, since that would be the commonality between the two tools.
The other interesting output is this:
% dmesg|tail
[ 280.973316] ath5k: phy0: too many interrupts, giving up for now
[ 280.989985] ath5k: phy0: too many interrupts, giving up for now

[ 281.034543] ath5k: phy0: too many interrupts, giving up for now
[ 281.049984] ath5k: phy0: too many interrupts, giving up for now
[ 281.064543] ath5k: phy0: too many interrupts, giving up for now
[ 281.079983] ath5k: phy0: too many interrupts, giving up for now
[ 281.094544] ath5k: phy0: too many interrupts, giving up for now
[ 281.109122] ath5k: phy0: too many interrupts, giving up for now
Looking at longer tails, this message repeats many many times, interspersed with:
net_ratelimit: 321 callbacks suppressed
With various values for 321. Some interrupt getting stuck would make sense for why the load average blows up, but I really don't know how to fix that ...
I verified on the ath5k site (http://wireless.kernel.org/en/users/Dri … rted_Chips) that my chip is supported:
% lspci
02:02.0 Ethernet controller: Qualcomm Atheros AR5211 Wireless Network Adapter [AR5001X 802.11ab] (rev 01)
Any tips for what might cause a stuck interrupt like that?

Why is my mac mini server apparently looking for wireless while I hold option at startup?

Besides the Lion recovery partition on my Mac Mini, I have 2 partitions: One with Lion and one with Snow Leopard Server that I often boot from in order to test some things. However, it takes FOREVER at the gray screen while I hold option, until the various startup disks appear.
There is a spinning wheel next to a popup menu button, and the wireless symbol. The Mac Mini is apparently looking for wireless for some specified time, then finally gives up and says, "Ok, here are your disk partitions." This is very annoying, and I would like to know what it is, and how to turn it off. My Mini is plugged into Ethernet.
Thanks,

Are there any Mount points setup or listed in Login Items?
Might try a variation of this from older OSes...
This command adds a delay, in this case 45 seconds, before displaying the Login Window.
defaults write /Library/Preferences/com.apple.loginwindow StartupDelay -int 45
If the Login Window UI detects that the network servers are available when it starts, it will skip the delay, also if network servers become available before the delay expires, the Login Window UI cancels the delay and displays.

Bummer..my phone quit scanning for wireless networks

in Baja on vacation and my phone suddenly stopped scanning for wireless networks. Got any ideas? My partners iphone works fine. I reset my wireless networks in the settings window. I tried manually entering the network name and pass code. I removed and replaced my sim card. I'm hesitant to synch, backup and reset my phones settings since I definitely don't want to compromise it further. Been there done that.

Here is a solution that might help. I too had the unhappy message of " could not scan for wireless networks". Thinking it was a wifi hardware problem or software problem made me give up until an idea hit me. Maybe it was an app. that was giving me problems. So I deleted an app. I had , which was Devicescape Easy Wifi, and did a reset network setting. This solved my problem. So look at your app. list and delete any wifi app. and see if that works.

IPad could not scan for wireless networks

My iPad 2 was bought in April 2011. And just a few hours ago it suddenly disconnected from my home WIFI.
I tried to reconnect it, but it either kept scanning the network or kept prompting the warning message "iPad could not scan for wireless networks".
My Macbook Pro, iPhone and another iPad 3 were all working fine with my two different WIFI points at home yet only my iPad 2 couldn't scan both WIFI at all.
I have tried to:
1. Reboot IOS (turn it off and on)
2. Take out sim card
3. Reset Network Settings
4 Reset All Settings
5. Restore iPad from iTune
I've called Apple, obviously they had no clues about this problem and they just adviced me to send in my iPad 2 for 1-to-1 change.
This seems to be a common unsolved issue for apple users. Has anyone solved this before?
Now I'm worrying will my iPad 3 get the same issue in future. it makes me quite frustrated

[SOLVED] Scan for wireless networks at boot

Lately I've been making extensive use of public wifi hotspots (libraries FTW), as mobile broadband is simply too unreliable to give me a persistent (and cheap) connection.
Is it possible to use some combination of netcfg and wifi-select (or similar tools) to scan for wireless networks at boot?
I've already got entries in rc.conf for my mobile dongle and automatically detecting ethernet connections, but it's pointless adding entries for whichever wireless profiles I might use as searching for these and discovering they don't exist just needlessly slows the boot process, whereas running something similar to wifi-select at boot (with a timeout so an unattended boot won't wait for me to make a selection) would avoid this.
* Obviously I could just wait until the system has booted and then bring up the interface I wanted manually, but generally I only reboot my system after updates, and I only download updates at a wifi hotspot, so I was hoping to automate something here.

Iphone 4S Message - "Could not scan for Wireless Networks"

For the last couple of days I have been getting a message, "Could not scan for wireless networks" when I try to connect to WiFi. WiFi connection is sporadic and intermitent at best when I do mange to connect. My phone is set to automatically recognize and connect to familiar networks. All other devices in the area currently have no issue recognizing and connecting to my home WiFi network. I have reset, turned on and off phone. Thanks for anyones suggestions. I have a feeling a trip dowtown to visit Apple is in the cards?

Hello there, MattBrear.
The following Knowledge Base article provides some in-depth steps to try in resolving your wi-fi connectivity issues:

If the first set of steps don't help, try the "Unable to locate..." steps, which involve resetting network settings.

NAC Out-of-Band Deployment for wireless networks

I am evaluating the NAC appliance for my wired and wireless users. I have read that the only way to deply NAC for wireless is in-band mode but it looks like the following link says that it is possible to deply NAC for wireless networks in-band or out-of-band mode:
"NAC Appliance can be deployed for WLANs as an in-band deployment for full-time endpoint scanning or out-of-band within a central site for periodic scanning to confirm posture compliance. The NAC Appliance server performs authentication, posture assessment, and remediation. The server securely controls authenticated and unauthenticated user traffic by managing traffic policies based on protocol/port or subnet, providing bandwidth policy management based on shared, or per-user bandwidth, or using time-based sessions and heartbeat controls. (Figure 1)"
http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps6521/prod_brochure0900aecd80355b2f_ps6128_Products_Brochure.html
Does anyone know if it is possible to use NAC out-of-band deployment for wireless networks? If you can point me to some documentation it will be appreciated.
Regards

Thanks Robert.
In my case I am planning to deploy a central NAC appliance at the main office to control some branch offices and local wired users at the main office. The NAC appliance will operate in out-of-band mode. But for wireless users at the main office I will need an aditional NAC appliance operating in in-band mode, is this correct?

TS1398 this didn't help me at all. out of the clear clue my iPad can't even scan for wireless networks. even when I type in my home wireless network name. my phone can connect to it but for whatever reason my iPad won't. nothing I've tried works. I'm ****

believe me I've tried EVERTHING and my iPad still 'can't scan for wireless networks'. it happened all of a sudden and is really really frustrating. I really don't want to have to drive 40 minutes to the nearest 'genius bar'. I'm about ready to break this thing over my knee. I've even tried the frig trick. it worked for about 30 seconds. and then? nothing. any non sarcastic suggestions?

Looking for Mac network professional to setup our small business network.

I've installed OS X Server on an iMac within our office to act as a file server and also allow us to access files using a VPN. Probably should have purchased a Mac Mini Server and will likely go that route in the end.
I'm computer savy, but little networks experience and just can't get this working correctly. If we had more time to dedicate to this and with help from this forum, I'm sure we could get it up and running. The goal is to get a simple network going that will allow us to access files, etc in the field and at our home offices with the ability to grow as our business expands.
At this time I'd really like to have someone just handle the setup of the network so we can get functionality asap. I've done some searches and looked for a network professional in our area with experience in Mac networking within a business environment, but haven't had much luck.
If anyone point me in a direction of someone that can help get this going I'd be forever greatful:)

I'm not a rocket scientist but I do have a working mail server and website using a mini mac and os x server (Mavericks).
It all begins with your DNS and I recommend you do use a mac mini with OS X Server as it's designed for that very purpose. You absolutely must get your DNS situation working first. There's a guy in this forum named Mr. Hoffman who is particularly useful (there are others) in this area. He has a website with lots of helpful advice and, in particular, this: http://labs.hoffmanlabs.com/node/1436.
However, before you embark on that journey, this is what you'll basically need to do:
You're going to need a public (external/public facing) DNS and a private (internal) DNS. Your private DNS (served by your os x server) needs to live behind some kind of hardware firewall/router to prevent the great unwashed and curious from venturing into places they probably shouldn't be venturing. It's port(s) should never be exposed to the outside world.
Get a static IP from your ISP and register a domain name.
Let your domain registrar provide the external DNS.
You'll want to set up an internal DNS using OS X Server in the 10.0.0.0/16 subnet (it doesn't seem to let you use 10.0.0.0/8 and it really hates 192.168.0.0/24).
The server itself will need to be "self-aware" by setting it's System Preferences > Network Preferences > DNS Server to 127.0.0.1.
Of course, once you get the DNS working you'll want to turn on File Sharing and then (and only then) Open Directory. THen you can begin adding other services such as web, mail, vpn, etc...
I'm sure there is lots more that I've missed but this should do for now. Good luck.

My experience with steaming with Apple products is done from iTunes, my music and video files from iTunes on my iMac or video from Apple Store. I sync photos and music from iTunes with iPhone, iPod Touch and AppleTV.
I have a 2TB external disk that has my iTunes library on it. All my music, TV and movies. It is hosted on my iMac
I do not know if mkv video can be played on the iPad, maybe there is an app that can do it. According to the iPad specifications the video files have to be "Video formats supported: H.264 video up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4 and .mov file formats; MPEG-4 video up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4 and .mov file formats; Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second, audio in ulaw, PCM stereo audio in .avi file format"

OS X keeps looking for missing network drive

Hi there,
I notice, I am not the first to ask the question, but is has not yet been answered and I'm a bit puzzled. I am using OS X 10.7 by now and ever since OS 10.6 I have noticed that - sometimes - finder seems to be looking for a network drive (a former time capsule) that is no longer mounted and available. Every once in a while I get the message that the drive "name" cannot be found.
Where can I check to get rid of any references to that old drive? It must be mapped somehwere, alas, I don't know where.
It is not in the startup items, I've checked there and there is no file sharing activated.
Thanks in advance, Alex.
