Airport signal drop after Microsoft applications launch

Ok here is the deal. I've recently noticed over the past several weeks that I would lose my Airport signal whenever I launch either Microsoft Entourage or Messanger.
It is truly bizarre. I have a Macbook Pro and I also have a Dell PC laptop and Dell PC desktop that all connect to the base station wirelessly.
Everything works fine until I try to launch one of those applications. I have to restart the base station to get the signal back. It is driving me mad.
Any ideas?

I had one AE base unit, where network connection would disapear every other day. The light would still be green on the AE, but the signal from the AE could not be picked up nor seen by the computer. Only turning the AE off and back on, would make it appear and work again. I Changed the AE unit, and I dont have the problem any more. I didnt change any settings at all.
So in my case, it was the AE base unit that was malfunctioning.
I have also seen similar problems with a different cause: That the wifi network card in the computer wasnt connected properly. ..
I dont think its a software problem
good luck

Weak Airport signal strength after MacBook upgrade to OS 10.5

Today, I finally upgraded my 13-inch 2.16 GHz Core 2 Duo MacBook (2 gig RAM, 160 gig HD) to OS 10.5 from OS 10.4.11. After using install and archive to install the new system, I noticed the Airport signal was down to three bars from the usual four. After completing all the system updates to bring it up to 10.5.8, its still receiving only three bars. We're using a 2Wire wireless DSL modem for Internet service. I was getting the full four bars before the system upgrade, and my wife's 14" G4 iBook is still getting four bars.
What's going on here? Is there an available fix for this? Or am I doomed to going back to OS 10.4.11?

Those bars are only an approximation of Wi-Fi signal strength. In Mac OS X 10.5 if you pull down the AirPort menu bar item while holding down an option key you'll see a value "RSSI", which is the actual signal strength. If you were using an AirPort base station, you could use AirPort Utility to see actual signal and noise levels.
In Mac OS X 10.4 I don't think that option key trick works, but you should be able to use the AirPort command-line utility, as describe in the electronic book "Take Control of Your 802.11n AirPort Network" (http://www.takecontrolbooks.com/airport-n):
- Launch Terminal
- Type this command:
cd /System/Library/PrivateFrameworks/\
Apple80211.framework/Versions/Current/Resources/
- Type this command:
./airport -s
You'll see the "RSSI" value in one of the columns. If you compare the "RSSI" values for both OS versions, you may find the "RSSI" values more similar than the AirPort menu bar arcs suggest.
I have no financial connection to Take Control Books.

Airport signal drops randomly

I use Airport Express to connect to wireless Internet. Recently I've had this problem where the signal just randomly drops every few hours - if not every hour. Airport Express is showing a green light.
When I re-start my computer then it still won't show the signal bar at the top. So I basically have to turn-off the computer and unplug the Airport Express to get it work.
I don't have this problem when I use wireless at other places.
Any advice on this problem?

I think my problem is fixed. You see I was using my airport express as a booster to my linksys, which worked for over a year until recent OS X update.
The Fix:
Instead of just setting up my express to join an "existing wireless network" , which was my original set up....I opted to use the option "Creat a wireless network" and I gave it another name, and under WDS tap I enabled it as a remote base station and under the "main airport ID" I selected my linksys router. Using the airport express this way, now I have two network names, the name of my main linksys router, and the name of my air express. Of course you get a better signal from one versus the other one depending how close you are. You also need to manually switch to the one with stronger signal, but at least both of them work through out the house, and my airport express has not dropped of for 3 days now. It works. Not sure why, but I am glad it works. If you are using your airport express a signal booster or as a remote base, and you are having your signal drops off, try to set it up this way, and see if it works for you.
I hope apple can shed some light to this issue, and I hope this works out for you

Nokia E6 - Signal Drop after every call

Hi,
I have started to face this problem for the last 8-10 days.
After every call is completed there is a signal drop for about 30-40 seconds. It drops to zero & then comes back to full strength again.
I have updated the phone software to the latest version and still have the same problem.
There is no problem if I use my sim card in any other phone.
Thanks for your solutions in advance.
Cheers
KD
Solved!
Go to Solution.

Hey,
Thanks a ton...working for me so far for the last 3 calls...
If only you had replied earlier ...it would have saved me from going to the Nokia Service Center, who told me to change my SIM card...which I did as well with no solution. LOL
I wonder where the nokia moderators are ..not even one reply for almost 3 days now..
anyways ..thanks a ton buddy
Cheers

Airport Signal Dropping

When I boot up I have full strength, then when I go to a web page the page loads and then the signal will drop. I reset airport and get full strength. I go to another page and the signal drops again and I reset and get full strength. I do this several times and the signal finally stays at full strength.
Is changing channels something that might fix this?
Thanks

You should probably check out the other threads here on wireless performance issues with the Macbook. This has been a big problem for many people.

Ipad 2 signal dropping after visit to genius bar??

How is that possible. I was concerned about the bleeding that I never addressed and now my wifi signal drops. I've tried to restore, turn off wifi, change to airplane mode and

Tap Settings > General > Reset > Reset Network Settings
Then restart your iPad> Hold the On/Off Sleep/Wake button down until the red slider appears. Slide your finger across the slider to turn off iPhone. To turn iPhone back on, press and hold the On/Off Sleep/Wake button until the Apple logo appears.
BTW, Airplane Mode disables Wi-Fi > iOS: Understanding airplane mode
If nothing above helped try here > Apple - Support - iPad - Wi-Fi

5.0.1 constant signal drop after every 2 minutes

As soon as I updated the software in 4s to 5.0.1 the neverending trouble started. There are constant signal drop resulting communication lost and despite the signal bar showing full strength. can any one help, Have already triesd the SIM PIN option can any one help? would really appreciate it

mAN?
with that type of config. you have? you should not have any problems.
especially with the intervideo program 'cause it captures in mpg and it is a very loose coding (better said no coding at all)
try turning the ht off through bios
or try this prog.

did you try recording on both (4) of your hdd's?

Signal drop after installing OS 4.0.1 - Apple 3GS 16GB

Hi,
I have installed OS 4.0.1 yesterday and immediatly noticed drop in signal strength.Signal strength came to half after installing it.
Any one else experiencing the same problem and any solution?
I know I can go back to old version rather than that any solution?
Thank you

Incorrect... it changed the equation for the display. the math was changed which is now affecting the actual connection.
No, it didn't.
the places i had full signal now only has half. the places i had a one bar now has none. this is all since the 4.1 update.
That sounds about right, as the update changes this.
so a software update does have the ability to affect things like signal if everything is based off the previous equation. you follow what im saying.
Again, no. The update does not change the actual signal your phone gets. It can't, as this is dependent on the cell tower's output power and how much of that is coupled into the antenna. That yields a certain signal strength number, expressed in dBm, which the phone then maps to a visualization in bars. This is done because most people have no idea what -100 dBm means, much less how much worse that is than -51dBm (which is all you'll ever get). A nice graph showing bar is pretty understandable, though, so phones use that.
How the raw numbers (dBm) map to bars is different per phone. You can not compare a Nokia phone to an iPhone, or an iPhone to a blackberry, or a blackberry to an HTC phone, etc. using just 'bars'. You need the raw numbers.
The 4.0.1 update changed how the different numbers map to bars. Nothing else changed, apart from some Exchange-related bug.
Here's a picture showing what happens. Keep in mind the actual signal strength (the line in the middle) does not change.

Airport signal drops

When playing music via iMac or iPad using my airport express through the hifi the signal repeatedly drops either for a second or two or more recently for hours. Any ideas?

Do you currently have the 802.11n AirPort Express Base Station (AXn) configured to "join" the wireless network provided by the BT HomeHub router? That is, within the AirPort Utility, does Wireless Mode = Join a wireless network?
Is the AXn in the same room, different room/floor from the HomeHub? Approximately how many feet apart are they? When the drop-outs occur, where is the iTunes host (iMac or iPad) located ... near the HomeHub, the AXn, or somewhere else?

Lost Airport signal drops connection over whole network!

Hi-
I have a G5 1.5 GHz tower (I think that's the right speed), running OS 10.4 and connecting to our cable line via Airport Extreme to our router. We also have a PC that is hardwired to the router. I was having trouble for a while with my connection dropping if the computer went to sleep, but that seems to have been fixed. In its place, though, is a worse problem- almost daily, I lose my signal, and it will knock our entire connection offline so that we have to unplug the whole setup in order to reconnect. It seems like this happens with high-traffic or graphic-intensive sites.
Do you think switching the channel will help in this case, or is there something else I should try? Please let me know if you need more information.
Thanks!

tcano, Welcome to the discussion area!
Changing the channel is free, quick, easy, painless, etc. so it is certainly something to try.

Sftdcc.exe does not timeout after closure of application launched via GP in kiosk mode.

We are configuring a group policy to launch an application upon login to the Remote Desktop Server.
The following group policy object is configured;
User Configuration\Policies\Administrative Templates\Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment
By default, Remote Desktop Services sessions provide access to the full Windows desktop, unless otherwise specified with this setting, by the server administrator, or by the user
in configuring the client connection. Enabling this setting overrides the "Start Program" settings set by the server administrator or user. The Start menu and Windows Desktop are not displayed, and when the user exits the program the session is automatically
logged off.

The application launches successfully.
Upon exiting the application the App-V client shuts the application down successfully but the RDS session does not log the user out or end the RDS session. The sftdcc.exe process
does not timeout.
Using Task Manager to end the sftdcc.exe process initiates the logout process.

There are two registry keys you can set for this problem to disappear:
HKEY_LOCAL_MACHINE\Software\Softricity\SoftGrid Client\CurrentVersion\Configuration\
Value Name: DCCSeamlessTimeout
Type: REG_DWORD
String: 0
I have tried adding the DCCSeamlessTimeout to the HKLM\Software\Wow6432Node\Microsoft\Softgrid\4.5\Client\Configuration
but this does not have any effect.

Updates on this issue.
if you are running window server 2008 R2 install this hot fix:
KB2815716-v2-x64
then add this registry values:
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\SysProcs" /v sftdcc.exe /t REG_DWORD /d 0
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\SysProcs" /v splwow64.exe /t REG_DWORD /d 0
then reboot, and that will fix it.
if you are running 2012 r2, then only add the registry values and reboot.

When iBook G4 wakes up, it drops Airport signal temporarily

My wife and I both have iBook G4s and we share the same Airport Extreme network. We have the most current software updates. When her iBook wakes up after being asleep, it temporarily drops the Airport signal. The signal reappears within a few seconds, but it takes 10-15 seconds to actually be able to access a website. Until then it comes up as "unavailable," which suggests the computer is logging into the network every time it wakes up, and that's the delay.
My laptop doesn't have this problem. It keeps the signal when it falls asleep. What might be causing this problem with hers?

Thanks for the link. When I started working through the process, I remembered that I had changed the "by default join" setting from "Automatic" to "Preferred Networks" a while back. I was having trouble with my laptop joining networks I didn't want it to. So I did some research and shifted to "Preferred Networks" and removed the networks I was unintentionally joining. My guess is it is this change, and not the 10.4.11 upgrade that caused my issue.
When I realized this, I didn't finish the steps on the link. I just changed back to "Automatic" and that seems to have taken care of it. If I find I'm having trouble with the Automatic setting, I'll try removing my encrypted network and then adding it back in, as suggested in the article.
Thanks so much.

Application Launch Failures after Update: shared library error

Soon after installing the latest Security and Operating System Updates, I discovered that I could no longer run Microsoft Office. I get the following error message when attempting to open any of the components: Application Launch Failure The application "Word" could not be launched because of a shared library error: "3<Microsoft Word><CarbonLib><CFMPriv_CommonPanels>" I have tried reinstalling the updates but it hasn't helped. I can't reinstall Office because the same error message comes up when I try to open the Microsoft installer. Can anyone help? I'm stuck. Thanks.

Again, thanks.
It's somewhat confusing. The folder /System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/CommonPanels. framework
contains 3 items, a gray screen marked Common Panels with a small arrow pointing to the lower left edge, a folder marked Versions (which holds folders marked A and Current), a folder marked Current (which has a small arrow pointing to the lower left edge and holds a gray screen marked Common Panels and a folder marked Resources) and a folder marked A (which also contains a gray screen marked Common Panels and a folder marked Resources. When I click the gray screen marked Common Panels, I get a message that there is no default application specified to open the document "CommonPanels".
I'm not sure what all that means. Are there too many Common Panel screens? Does the small arrow have any significance? I've also discovered that, in addition to not being able to run Office, I can't install any new applications (same CarbonLib error message). If you think I need to archive and install the System, I can try to do so.

Airport signal becomes MUCH worse after 10.4.7 update?

Airport signal in 10.4.7 is 50% of what it was in 10.4.6. It also now cuts in and out. What changed?
And how can one go back to the good signals and stable reception under 10.4.6?
Mac OS X (10.4.7)

Yes, I'm noticing the same. It first hits 4 bars,
but then goes down to 2 after a minute or so. Then
it drops in and out consistently.
Am trying to find a solution before I kick something.
I switched my settings on internet to 802.11b, and now I have great connection on all my computers...b ... not g/b or g.It has been steady for a month now. Cheers

Application launch failed. Ensure that the device screen is unlocked - after the phone update

I have the following error "
Error 1 Application launch failed. Ensure that the device screen is unlocked and device is developer unlocked. For details on developer unlock, visit http://go.microsoft.com/fwlink/?LinkId=195284. 0 0
I'm pretty sure it happened after the last update. I was able to use my phone as a dev one before
and my account shows it as a registered device.
The OS version is 7.10.8107.79.
The steps that I tired
-Registered again my phone with the registration tool
-Check the issue with Zune auto-launcher (zune isn't syncing and the phone is connected)
-Close and start everything again
Other possible issues
- Do I have to have sdk 7.1 to deploy?
- Do I have to wait 24h for registration?

You should be using SDK 7.1 anyway, so install that.
After the update, the phone may have locked itself. This may not be reflected in your AppHub account though. Using the Developer Registration Tool, register the device, unregister it, then register it again.
