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

Airport signal becomes very weak while windows partition internet is fast.

I just recently bought a macbook about a month ago. A couple days later I ran boot camp and boot windows vista on the macbook. What I've noticed throughout the past few weeks is that internet explorer on the windows partition is much faster and it can receive a better connection throughout my house. There are virtually no problems with the signal. When I switch back to the mac operating system the internet connection signal is only about halfway, or like two bars. The speed has also greatly decreased. I've tried everything when it comes to changing the DNS serves and it doesn't work.
Help would be greatly appreciated!

This has seemed to be a problem with some MBPs but I also have friends that sometimes complain of the same problems on powerbooks.
Sometimes you have to remember that it's website dependent - when you're having the problem, if you haven't already, try opening up another website in another tab to see if there's any improvement.
You could also try Firefox, as many people rave that it's faster then safari.
Unfortunately that's all I can offer you on this subject, but i'm interested in seeing the responses!

My font totally changed after the last Firefox update. It is a little smaller, less bold and very much less clear. Please tell me how to fix this.

The default font used on websites like Facebook, Craigslist, Google etc. has now become much worse since the last update. It is much less clear, it almost looks choppy and transparent. As if part of the letters are missing. Less bold and just a tad smaller as well. I would like to go back to the way the font used to look like, the way it does in Internet Explorer and Chrome.

hi miked91, this is probably caused by microsoft update kb3013455 which can cause font rendering issues on vista:
<blockquote>After you install security update 3013455, you may notice some text quality degradation in certain scenarios. The problem only occurs on systems that are running Windows Vista SP2 or Windows Server 2003 SP2. Microsoft is researching this problem and will post more information in this article when the information becomes available. </blockquote>
<sup>reference: https://support.microsoft.com/kb/3013455</sup>
one option may be to [http://windows.microsoft.com/en-us/windows/remove-update#1TC=windows-vista roll-back this particular update] for now until there is a fix by microsoft or you could also look if there is a [[Upgrade your graphics drivers to use hardware acceleration and WebGL|graphics driver update]] available on the website of the vendor (intel/amd/nvidia) which might also resolve this problem in some cases.

Why are my legira hfm36 files so much bigger after import to iMovie?

Hello
When i import files from my camcord legira hfm36 the files become much lagrer after import... :-/
What is wrong, i use 32gb sdhc card in cam and When i import it All it Will take 270 gb space??? Why...
Palle

AVCHD which is likely the format you are shooting in create a .mts or .m2ts file that is highly, highly compressed as it is saved onto the camera. When it is decompressed and imported into iMovie it can expand up to between 40+ and at a max 75 Gbytes for each hour of video shot. So there's no free lunch when you shoot High Definition video on the typical AVCHD video cam, the space available you have to expand those video clips is going to evaporate very quickly. So consider purchasing an external USB hard drive as quickly as possible.

IPad2 Issues after iOS 8.1 update

iPad2 64g wifi + cellular -   very slow and non-responsive since iOS 8.1 update. nonstandard Apps seem to be working fine.. it’s the standard item like photos and safari that don't respond.
photos - (which I use daily to show clients examples) will freeze and kick me out back to the home page when trying to do anything from open a photo for viewing to trying to delete a photo. Edit.. forget it.   better off using an alternate app to edit a photo as it locks up and crashes every time.   I really need to be able to view the photos on my iPad2
safari -   good luck using any hyper link…. It doesn’t respond.   Even at Apple’s website.   Sometimes it crashes but most of the time it just ignores me like I haven’t touched the screen
Overall - the touch screen is glitchy since the iOS 8.1 update. It was slow after the iOS 8.0 update but has become almost unusable after the 8.1 update.
I cannot afford to purchase a new iPad. And I really need to find a way to make this one work.
I did read about how to restore to an older iOS version.   The only problems are all of my laptop is Windows based and the instructions assumed you had a Mac.   I did a backup to iTunes prior to the 8.0 update but I have also done backups since.   So I am not sure I have a “clean” iOS 7 backup.
Any ideas would be appreciated   Thank you in advance for your help

For the touch issues in Safari, does scrolling or zooming the page before you try to tap a link make it work again? I've read a few posts that this may be a workaround for that issue.

Premiere Pro CC and After Effects CC work slowly together - much worse than CS6

Premiere Pro CS6 and After Effects CS6 worked together really well. I could have both programs open and make a change in After Effects, then go back to Premiere Pro and see the changes pretty quickly. Since upgrading both to CC, I can't jump back and forth and see the changes quickly. I literally have to hit Enter and render the After Effect clip after every freakin' time I make a change to it in order to see it without any pauses or jumpiness in the playback. CS6 worked great. I can't express my disappointment in the Creative Cloud "upgrade". So many things are SO MUCH WORSE!!! Adobe you have to fix this stuff.

The speed of the connection is dependent on your hardware and the type of comp you have in AE.
I haven't noticed any significant performance difference between the two versions (I've also been heavily using dynamic link since CS6 ).
Some comps will play fine in Premiere, some comps will need rendering. I generally render the clip in Premiere, as opposed to AE.
If the same comp from CS6 is behaving significantly worse in CC, then you might be on to something, but it is most likely a bug isolated to your hardware config and not a general CC issue.

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 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

Trouble connecting to Airport after installing latest security update

Hi, I have just spent an hour with a level 2 SBC DSL tech and they could not resolve my problem. The problem is this: After installing the latest security update released on March 13 for OS 10.3.9, I can no longer securely connect to my airport. It may have something to do with the keychain because this has happened several times before, most recently after the previous security update about 2 weeks ago. Usually after much playing around, I get a window asking for permission for my new network settings to access the keychain. Once I say yes, all works fine. This time, I am not getting that prompt. Even though I have a full signal showing I am connected to the base, it will not pick up and IP address. Finally, the SBC tech had me disable the wireless key on the desktop pc that is the primary computer on the system and immediately my connections works. If I enable the wireless security key, I lose the connection. As I am completely open to hackers with the wireless security disabled, this is a big problem. PLEASE, PLEASE, PLEASE can anybody help me?! Thank you so much for your help!

Hi, my first post here!
I too experienced this problem this evening, after applying the latest security update to Panther. I had verified that the wireless base station was working correctly and that it's WEP key hadn't become corrupted. There were no error messages after re-starting the Mac, just no IP number via airport.
The keychain utility would hang if any attempt was made to alter the password for WEP, and the airport utility hung too. I used Disc Utility to verify permissions, which found dozens of errors - haven't done any maintenance for months - and fixed them.
On re-starting, Airport was 'OFF' so turned it on, was asked to allow access to keychain, and all is working again.
Thank you to those of you who posted the suggestion about permissions, you certainly saved my evening!

Airport & Bluetooth problems after 10.4.7 update

(Note: I posted this in the Tiger forums and after no response, thought I'd try here.)
Greetings,
After updating to 10.4.7, my iMac G5 20" iSight exhibits occasional loss of signal strength in the Airport and poor or lost Bluetooth connections with the wireless keyboard and mouse.
The Airport and Bluetooth problems happen together at the same time. I can see the Airport signal strength drop and seconds later the mouse starts becoming slow and I usually lose connectivity with my keyboard. After about 10 minutes, signal strength returns on both.
The system is well isolated from interference, the cordless phone is a 5 ghz unit, and all cellphones have been removed from the room, but the symptoms continue. The wireless G router is only 3 meters away in the same room.
I reapplied the combo 10.4.7 updater, repaired permissions, cleaned caches using Applejack, zapped the PRAM and reset the SMU but the problem still happens.
Any suggestions? It is driving me crazy.
Thanks in advance for any help.

I'll add a "here, here". I have a 20" iMac G5 (1.8 GHZ). Since applying 10.4.7 I have had Bluetooth disappear twice. Disappear as in: keyboard and mouse no longer function and the bluetooth icon in the menu bar disappears. Power cycle works to recover the system. A far from elegant workaround.

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.

Macbook - Constant Poor Airport Signal

Hi guys,
I've had my macbook for about 5 years now, and in the last 3-4 months i've been having some annoying issues with my airport connectivity, i've finally decided to try and sort this out! The problem is that my macbook has become terrible at picking up airport signal... whereas other computers, ipads, xbox 360 and such can pick up the signal absolutely fine, I have to move very close to the hub to get any signal at all. Now for example I am sitting about 3-4 meters away from the hub and I am getting 1-2 bars! ***!!
Its not anything to do with the network as I have tried in several different locations and with the same results... no signal unless I have literally right next the the airport sender box thingy (hub). Could it be something to do with the software? Or perhaps the airport card is playing up? If so can I get a new card?
Any help would be greatly appreciated....
I guess a system spec would also be helpful so I have:
Processor: 2GHz Intel Core Duo
Memory: 2 GB 667MHz DDR2 SDRAM
Operating System: 10.4.11
Airport Card Info:
Card type: Airport Extreme (0x168C, 0x86)
Wireless Card Locale: Worldwide
Wireless Card Firmware Version: 1.4.4

Hi Dillweed
Here are some options that might help:
- Restarting the router
- Creating a new location (see below)
At 5 years old, it's possible your AirPort card is on its way out. If you can't afford to change it then you could try:
- Connecting with an Ethernet cable (always gives the best connections and faster speeds!)
- Buying a USB wireless dongle.
Bob
PS: Creating a new "Location":
System Preferences > Network
Select the AirPort from the left hand side
Click on the Locations combo box and select Edit Locations...
Click on + to add a new location, call it "Home" (or anything else you prefer)
Click on Advanced
Select the AirPort tab and enter your network name
Select TCP/IP tab.
Configure IPv4 Using DHCP
Now click on Renew DHCP Lease. After a few seconds you should get an IP address (probably 192.168.x.x)
Click on Proxies tab.
Select Auto Proxy Discovery and Use Passive FTP
Click on OK and Apply, etc.

Airport signal anomaly

when waking from sleep or startup
i get a week airport signal 4 or 5 bars
signal is restored to full strength only after selecting my network from the airport menu
the network is already selected but somehow clicking on it brings it up to standard.
thanks for the help

Probably the same bug affecting sustained connectivity. On mine too, toggling the Airport connection returns full signal, then after a while it either erodes or becomes erratic. I don't have a clue but it feels like a power management issue that could be fixed by software update just as soon as Apple release a solution. Meanwhile maybe submit a bug report:

My 2011 Macbook has become exceedingly slow after upgrading to Mountain Lion.

I have a 2011 Macbook which has become really slow after I upgraded to Mountain Lion in March. At first it wasn't that bad, but it's getting worse and my computer has begun to overheat even if I'm only using Google Chrome. I used to be able to keep multiple applications open at once and never closed many of them, but now if I want to get anything done I have to use the absolute minimum. My CPU has reached 86 degrees Celsius and temperatures slightly below this seem to be the average, even if I've only been on for ten minutes. It heats up VERY quickly. The fan has been operating at 2919 rpm, but it has said that for days and I don't know if this number should be changing? (I know that normal is about 2000 rpm, so I know it shouldn't be that high anyway.)
I'm currently working on cleaning out my harddrive of duplicate and unnecessary files and I plan on restoring to the default settings and backing everything up on an external harddrive... but are there other things I should be doing to speed my computer back up, like good programs to clean out my computer's temporary memory on a regular basis? The problem seems to have come on pretty fast though, so I don't know if there could be something else wrong with it and if I should take it into an Apple-approved repair place.
Also, I'm not one to illegally download/pirate things from sketchy websites, so I highly doubt a virus is the cause, especially given that Macs rarely get viruses.
Any suggestions of what to do and what programs/apps to install would be greatly appreciated! Thank you!

Cellular signal becomes false positive

Everything works fine, except after a while the cellular signal becomes a false positive. By this I mean the upper left corner continue to read "Verizon 4G LTE" with a few bars, but there's actually no signal. All apps that require the Internet doesn't work. It's an easy fix though — in Settings, the Cellular Data has to be turned off, then turned back on. And by "after a while" I mean when it falls into sleep mode after a FaceTime session, then awoken. Not sure exactly how long afterwards. Not sure if it's consistently after one nap or longer. Not sure if running other apps would do the same thing.
Question is:
Is this normal?
I can imagine the upside is that you don't waste data in a prepaid data plan like when background apps continue to run.
The dreadful downside, however, is that any incoming FaceTime call cannot get through.
If this is NOT normal, is it a common glitch/bug/quirk? And how to fix it?
iPad3, OS 6.0.1

You can't begin measuring velocity until it is positive unless you have already been measuring velocity.
The solution is to always do the measurement. Evaluate it with a >0. In the true condition, then do whatever it is you want to do.

Airport signal becomes MUCH worse after 10.4.7 update?
