Greatly reduced reception

Problem:
I'm experiencing greatly reduced reception/range with my PowerBook wireless connections. More than 15 feet away from my base station can cause dropped or intermittent connections or complete loss of signal. Any line of sight interference - a wall, a window, a chair, my leg - will cause signal problems.
Notes:
*This computer, base station and Airport card used to have fantastic range and reception on this and all other wireless networks.
*I now have awful range on all wireless networks.
*All other computers have great reception on my network.
*The problem seemed to come on gradually, rather than all at once.
I've tried:
*Checking/re-seating the Airport card and connections to the computer.
*Checking antenna connection to the card.
*Inspected antenna wire and checked continuity.
*Swapping in other Airport cards known to work well.
*Zapped PRAM over the course of the problem.
None of the above helps.
Any ideas? What else in the computer affects reception besides the Airport card and the antenna?
This is a PowerBook G4 Titanium, running 10.4.10.
Thank you

It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing you from getting a good clean signal.
I suggest you perform a simple site survey, using utilities like KisMAC, MacStumbler, iStumbler, or IPNetMonitorX to determine potential areas of interference...and then, try to either eliminate or significantly reduce them.

Wifi range greatly reduced after ios 7 update

Ipad 3
Everything was running great. I even got reception out in the hack yard. After the ios 7 update, the wifi drops when I get farther than 10 feet from the router.
I tried rebooting the router and resetting network preferences and also a complete wipe and default install. Nothing has worked.

Try a Restart.
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
Resetting your settings
You can also try resetting all settings. Settings>General>Reset>Reset All Settings. You will have to enter all of your device settings again.... All of the settings in the settings app will have to be re-entered. You won't lose any data, but it takes time to enter all of the settings again.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears. Apple recommends this only if you are unable to restart it.
Or if this doesn't work and nobody else on the blog doesn't have a better idea you can contact Apple.

Greatly reduced action performance in CS5

The bug issue text below wouldn't fit in the bug report form even though it's less than 2000 characters (another bug, perhaps?)
******BUG******
Concise problem statement: reduced performance in Action processing in CS5 compared to CS3
Steps to reproduce bug:
1. Create an image file, 8000 by 9880 pixels 16-bit RGB color.
2. The background can be any image, though I was using a scan of a test target with colored patches for scanner calibration.
3. Create a layer "final target" on top of the background. Set contents to transparent.
4. Create a selection 295 pixels on a side with rectangular marquee tool. Position this selection in the upper left corner.
5. Save the selection to an alpha channel "Grid Box."
6. Run an action with the following steps.
a. Load the selection "Grid Box."
b. Select the layer "final target"
c. Expand the selection 2 pixels.
d. Fill the selection with the foreground color.
e. Set the foreground color to white.
f. Select the background layer.
g. Move the selection 295 pixels to the right.
h. Save the new selection as "Grid Box", replacing the channel.
The use of this action:
Use the eyedropper tool to select a color from the center of the selected square, then use the magic wand tool to subtract from the selection using the color in the center of the square in contiguous mode with tolerance set to 8. Then run the action, and repeat the above process in the next selected square. In the scan I am preparing, there is a grid of colored squares surrounded by a large black border. The final result needs the black border eliminated so that the colored squares completely butt up against each other spaced 295 pixels apart.
So by running the action, the color in the center of each box is copied to fill the rest of the square selected area that's black, leaving the center portion intact. The copied colors go on the "final target" layer so the background layer is not disturbed.
If you need a copy of the action and/or the image file, contact me by email.
Results: In CS5 the action is unusable due to the long run time.
Expected results: In CS3 it works perfectly.

My theory initially was that you had given Photoshop just enough RAM to work efficiently with your CS3 setup, but perhaps because of differences in your Photoshop RAM setting or perhaps because Photoshop CS5 has more code in memory, it's starving for RAM under the same test, and goes to its scratch file for relief.
I created a test image and tried your action with a stopwatch.
Photoshop CS5 x64 on Windows 7 x64 (i.e., with plenty of RAM) takes 1.8 seconds to run through your action.
Photoshop CS5 32 bit consistently takes 6.8 seconds to go through the same steps. Notably it stalls on the Expand and Select layer "Background" steps for a few seconds each, where it blazed right through them in the 64 bit version.
In my case I have given Photoshop CS5 2897 MB to work with (89%). This number is larger on a 64 bit system than what you can set because Photoshop 32 bit can use up to a 3 GB address space.
I'll do tests next with earlier versions of Photoshop.

Itouch is slow and range greatly reduced

I just purchased a airport extreme and set it up. My iMac is runing fast via wifi and the printer is working as advertised. My problem is my itouch connects about 50% of the time and when it does, it is very slow and the range is basically reduced to the room the airport is in.
I used to have a dynex g router and my iMac ran slow but my itouch was very fast and I could go anywhere in the house and outside the immediate house. Any help for getting my itouch to work with the airport extreme is appreciated.

Sorry, I probably should have said what I have already tried:
I've tried this solution several times which hasn't helped. Thanks for the suggestions though.
I have also reset the network/ipad settings, soft reset the ipad, moved my router, and toggled wifi on and off, but no luck.
It's annoying as it was working no problem until after the update, the first few days were fine.

TS1398 My I pad is 14 motnhs old and previously worked fine on my home wireless network. All other devices work fine, but now, my I pads capability (range) is greatly reduced. Is there anything to check on the ipad for WIFI antenna strength?

My Ipad is 14 months old and previoulsy worked fine on my home wi fi network. Recently the range is diminished but all other devices (ipods, ps) are working just fine. Is there anything to check functionality of the wi fi antenna? Has anyone has similar problems? Unfortunately, the warranty expired 2 months ago.

Images open in PS4 greatly reduced in viewer

If I open PS4 and open a previously saved file, the window opens with a tiny speck in the middle. Titlebar confirms that the image is .054% of size. When I use the zoom tool, 8 or 10 clicks brings it back to the correct magnification. If I left click and choose "fit on screen", the window returns to the postage stamp sized window with the tiny speck. I have obviously changed something in the settings but it is beyond me to figure out what it was.
Does anyone have some advice on how to correct this problem?
g@46

I haven’t encountered that problem yet, but as with all unexplainable Photoshop-problems You might try trashing the prefs (after making sure all customized settings like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences You’ve changed) by pressing command-alt-shift on starting the program.

Mplayer cache option greatly reduces performance

Hi. I needed a larger cache because I have some videos stored on another samba server and it's laggy.
I set options: cache=20000, cache-min=10 , and that helped to play those videos smoothly, but that caused all 1280x720 mp4 files stored on my local drive to lag and A/V desync with mplayer message:
**** Your system is too SLOW to play this! ****
I tried cache values from 1000 to 80000, and they lag in any case. But without the option "cache" these videos play well.
Now I commented "cache" in config.
[default]
#cache=65536
#cache-min=10
ao=alsa
softvol=yes
subcp=enca:ru:cp1251
af=pan=2:1:0:0:1:1:0:0:1:0.5:0.5:1:1
ass=yes

you can use different config for your local usage.

Since upgrading to firefox 4, pages open up at a greatly reduced size, and i have zoom in with ctl+ about 10 times, which is then remembered, so the next time it opens at the right size.

i just upgraded to firefox 4 grudgingly, as i had this same issue when i upgraded to ff3, which i ultimately dumped, and went back to an older version. pages open very very small and i have to zoom in, to fill the page, and make it readable. once i have done that, those proportions are somehow remembered, and from that point on, they will open up at a large size.
how can i get ALL pages to open up to a standard. predetermined size?
on a related note, the toolbars are also very small. can i make them larger somehow?

That is a problem with the Flash plugin.
You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Internet speed has greatly reduced ... what can I do

I have a MacBook Air. In the past 6 weeks, access to the internet has slowed. It is not the location, as the speed to load pages or the inability to load entire pages is a problem. I am having problems more then 80% of the time. Have never encountered problems like this before. Any suggestions.

Given that there are very few mind readers or remote viewers in the user help community it probably would be useful for you to provide a bit more information

Nokia 6500 update- now reception has been reduced.

Hi,
as above really. Used the updater, great hope it fixes the phone freezing bug..
But, now coverage and service has been greatly reduced, it used to work fine in my house, now I cannot get a signal.
Whats changed?
thanks

two and a half months on and the answer is no - this has not been resolved yet.
we are on 3.
At home we have constant problem with "no network coverage" on our new 6500 slider. put the sim card in a 4 year old 6680 and we get 4 bars. same in various places in and around where we live, there is a place in croyon where it does seem to work though.
3 acknowledge its a known issue (I have seen mails going back to April about it) and that they are working with Nokia to try and resolve it. However if you dont make a fuss about it within the 14 day cool off period they wont do a thing about fixing it or replacing it with an equivalent model

My IPhone 3G reception fixed, a new problem - AT&T *real* data speeds

I've read quite a few topics on this forum regarding the poor IPhone 3G reception, and unfortunately 99% of them are emotions, making it very laborious to distill useful info out of them.
Therefore I'd like to post my personal experience so far with IPhone 3g, listing more facts, than emotions. *I hope this will help some of you, and also hope that others will follow a more structured approach to reporting IPhone 3g problems*.
*IPhone 3G Model MB046LL, 2.0.1 firmware*
I got my IPhone 3g black 16gb version in NJ on August 2nd, model MB046LL. I work in IT, and I was overall very impressed with all of its features. However, the device had 2 major problems - 3g reception was highly unstable, and the actual 3g data speeds were far lower than advertised, 200kb on average for download and 30kb on average for upload.
I called AT&T, they said I was in the zone with "the best 3g coverage". I went to an AT&T store, and had my SIM card swapped from #3022 to a newer one, #4022. Swapping the SIM card drastically improved both 3g reception and the data speeds.
Unfortunately, I noticed that my IPhone 3g was picking up not as many bars of 3g as other Iphone 3g sitting next to me. The actual dbm numbers for 3g were also smaller. I would continue having dropped calls. I also noticed that my battery would fully recharge very fast (within 1.3 hours), and would fully discharge much faster than it was advertised. The GPS was acting weird, and the voice quality would sometimes be horrible even with 5 bars of 3g. There were more anomalies with that phone, e.g. download speed of 20-30kb with 5 bars of 3g, among other things. I would diligently take screenshots of every anomaly I saw, and store them on the phone. Restoring the phone to its factory state did not help.
After some time, I concluded there was still something wrong my IPhone, scheduled a Genius Bar appointment, and had it replaced with a brand new IPhone 3g. Having numerous screenshots of different problems minimized the explanations to a minimum.
*IPhone 3G Model MB048LL, 2.0.1 firmware*
I had a chance to compare the new model with the previous one I had - the build felt a bit different. The screen on this new model has a slightly better contrast, too (compared default factory settings).
*The new model, however, has GREAT 3g reception*. Where with the previous model I had 2-3 bars of 3g, I now have 5 bars. The dbm numbers are also somewhat improved. I had a couple of small issues with apps, etc., but I figured them out - found which apps were crashing the system, and deleted them, cleaned up the old backups and the crash diagnostic crash reports from the previous model, etc. Finally all other problems I was having with the previous model are now gone, too, except the quirkiness of the GPS, but I suspect it's the new firmware, and not much I can do about it. I have yet to see a dropped call on this new model.
However this new model identified a new problem, something that I'd suspected for some time: it appears that the problems people are having could indeed be the combination of IPhone hardware/software and AT&T network.
I noticed the data speeds vary significantly throughout the day, even when you sit at the same desk. I noticed the speed drops significantly approximately during lunch time to ~90-300kb for download, would be ok during the day (~200-350kb for download), and would be AWESOME after 10pm - ~0.9 - 1.4Mbs.
One can make a conclusion here that AT&T simply does not have enough network capacity to handle the peak data load, when many people connect on the network. It could be that IPhone's software does not manage very well under such conditions, but I'd would place more blame on AT&T in this case, considering how exceptionally well IPhone performs during other times.
I'd like to point out that although both Apple and AT&T reps were genuinely trying to be helpful, I could clearly see that not one person I talked to on both sides did not have a clear solution how to resolve the problems I was having. Basically, I had to figure out what the problem could be, and use the resources available to try to solve it - be that replacing the phone, restoring from backups, monitoring the crash logs for problematic apps, etc.

I would constructively suggest that you edit your post pretty quickly if you want to avoid a highly deserved, verbal battering from every unemotional, highly rational and intelligent poster on this forum who might take offence to your demeaning attitude. I think to assume that because people who have posted on here have posted at all because they are emotional basket-cases, or in some way out of control of their emotions merely because they have aired their disappointment/disgust/anger with their sub-functioning iPhones is pretty insulting and undeserved. Whatever YOU have written here, or have experienced elsewhere, still only has the value of 1 (ONE). It is a poll of 1. It is an opinion of 1. No more valid than that, no more authority than that.

How do you reduce file size of a PDF if Save As doesnt work?

I have been trying to reduce the size of a PDF, using the Save As > Optimized PDF method.
I have also tried Save As > Reduced Size PDF.
This is on a file made up of 20 pages of full page Jpegs. (These were generated by the script in Photoshop that generates Jpeg files from Layer Comps within the document.)
If I use Reduced Size PDF, I get a greatly reduced file size but the image quality suffers greatly. (Lots of artifacts and blurryness)
There are no options to choose the level of compression I want.
If I use Optimized PDF method, I cant seem to reduce the file size no matter what I set the Jpeg compression to.
Is there some way to cut the size of the file down but not lose so much image quality?
Any suggestions?

Part of the problem here is that the files that are produced when I run the script to output files from layer comps are very big.
If I "save for web" for each layer comp, I wind up with way smaller Jpegs. Thus a much smaller PDF.
So the question is: Can you make the script, Layer Comps to Files, create smaller more optimized Jpegs? (Like you get when you save for web)

AIRPORT EXRESS with airtunes - MAC MINI RECEPTION

HI MAC BOFFS,
I have just managed to configure a an airport express with airtunes, and managed to get it on the network, but music keeps dropping from the remote speakers. When i get sound it is excellent quality but only for a few seconds.
I have noticed that my reception bar on the top rights does fluctuate and at best is half (and has always) but for internet purposes it never bothered me.
The appartment is stud walls and i have put the router on ch 1 if this helps.:(
Is there anything i should do?
thank you.
i sot

1) The Mac Mini doesn't have great wireless reception. Try experimenting with the Mac mini in the same room to make sure that it is indeed the reception causing your headache. If it is, there are some Mac Mini wireless reception hacks on the 'net.
2) Are you in an apartment? It is possible that there are many wireless networks around from your neighbors and if they are unencrypted your Mac / AE may be hopping between different networks.

Worse 3G reception after 2.0.2

I applied the update, did a hard reboot of the phone, and headed out for the night. In places I was getting great 3G reception before the latest update, I am now hardly getting service. This is truly crazy. In my NYC apartment I had always got 3 -5 bars and now I am barely getting 3G. And, no, this is not a question of just the number of bars. Before the update I could make calls with very few drops in my apt and now I am getting "called failed" more times than not.

Same here in Jersey City. 2.0.2 broke our two iPhones!
Reliable 3G data is non-existent now.
The iPhone 3G, if you dare to turn on 3G, is superfast data for five minutes and then it just slowly degrades into non-responsiveness.
You can get it back by turning 3G off and then on again -- but who wants to do that every 20 minutes?
2.0.2 forced us to turn off 3G on both phones for good and I am at a loss for words (and data!) now.
What a mess.

Dramatically reduce the amt of space used by OSX

I have a late 09' Mac Mini that's recently been upgraded from 2GB to 8GB of DDR3 1066Mhz RAM.
Plus, it's had it's 2.5" 5400RPM 160GB HDD replaced by a 240GB SSD...
With SSD's, it's typically a good idea to have at least 10% of the total capacity allocated as free space (how much depends on the SSD)
I just upgraded from SL (with all the latest updates applied) to Mavericks, & I noticed that the latter is using far more space.*
On SL 7.1GB was used & on Mavericks 11.6GB is now used, & I haven't even applied all the latest updates to Mavericks yet!**
Looking for tips on how to greatly reduce the space used, without greatly reducing the capability/functionality/utility of the OS.
Thank-you.
*both were clean OSX installs, only native/stock apps, no 3rd-party ones yet
**actually, it looks like it's auto-updated to the latest build of OSX, I just used the update tool & the only update left was for iBooks

Tony T1 wrote:
My guess is that the space increased was due to the sleep image increase when you added 6G of RAM.
You can have the mini only use RAM for sleep.
The downside is that if you loose power while sleeping, then the sleep image will be gone. Updside is 8G of diskspace reclaimed.
In Terminal, run:
    pmset -g
Look for hibernatemode
     If it's hibernatemode=3, then "The system will store a copy of memory to persistent storage (the disk)"
     If it's hibernatemode=0, then "The system will not back memory up to persistent storage"
If hibernatemode=3, look for the sleepimage with:
     ls -l /var/vm/sleepimage
To reclaim disk space:
In Terminal:
     sudo pmset hibernatemode 0
Then you have to remove the sleepimage with:
     sudo rm -i /var/vm/sleepimage
For more infor, see: man pmset
Okay finally had a chance to check this, nope it's set to: hibernatemode 0
Also did a ls -l /var/vm/sleepimage & got: "No so such file or directory"
I also did a ls -al in /var/vm & saw 2x swapfiles which seem to be taking a considerable amount of space.
These generally shouldn't be touched, right?
After reading that article you linked to & others it linked to, + some other reading before them, I'm 100% sure I don't want hibernatemode 1.
Resume/Autosave/Versions etc, + the FS's natural journaling abiities are more than enough for a desktop like the Mini.
So back to my original question, what else can be done to reduce space used?
I've done lots of research/reading since, but I'm still not 100% happy with the reductions.
I've come a long way though, largely by using symlinks to redirect data heavy dirs in my home dir, haven't touched ~/Library & am reluctant to for various reasons.
