Lots of problems with Airport Network???
Hi,
My experience with the Airport Extreme wireless network has not been positive at all. I don't know about other brands of wireless networks - maybe they are all like this? Maybe it is a wireless thing. The problems range from base stations just dropping out and going "orange" for no apparent reason, randomly - they will work for weeks at a time, they just drop out - to extremely slow local area network access, with relatively little or no other network traffic going on - remote desktop in particular sometimes slows to an absolute crawl and it's very frustrating, then I have to traverse to the other end of the building to access the machine I'm working on directly just to get that work done. I'm not a WIFI expert, but I've tried reassigning the base stations to other channels, tried the interference option, and a few other things. I just find it's very unreliable, coverage is very poor in this building, and no matter what I do it seems to have the same below average result. I like Apple a lot, but these systems and their lacklustre "we help you set up one WDS system and that's it further support costs $xx.xx " telephone support was disappointing. I was surprised to be honest, most of my other dealings with apple support and hardware has been good or excellent.
Anyone know what I can do? They all have the latest firmware / software updates, and I have 3 stations, one main hooked up to broadband, and two remotes.
M.
I can not help you other then to say I have experienced some of what you have. I live with it because I love it and to solve my issue all I have to do is unplug the base unit and re-plug it in. It works, sorry if this is not satisfy or works for you. I have same issue with cable TV, with internet and with IVOP but I live I use and it works.

Lots of problems with AirPort Express
I've got a lot of problems switching to an Apple Time Capsule and AirPort Express, so I posted them all here.
First of all, I got a new time capsule and airport express. When I first plugged in the time capsule and tested it, it loaded my home page instantly. So I tried clicking on tabs on apple,s website, all loaded in less than a second. I thought they were cached pages, so I loaded pages I never went to and they all loaded in less then a second. Then I exited safari, and the next time i used it it was back to normal speed, 5-10 seconds a page. Not exactly a problem but just wondering if any ideas on how to get that speed back.
Secondly, I set up my airport express. I planned on using it mainly for airtunes, but set it up to also extend my network. First time using it, AirTunes played, started crackling, then stopped. Now i get the error -15000 message.
Thirdly, the next day my computer wont load the internet when on one side of the house when hooked up to my TC network. I get 3 or 4 bars, yet the internet wont work. I tried checking AirPort Utility, and found my computer no longer locates my AirPort express... yet the light was green. So I reset it. Now all it does is blink yellow and STILL doesnt get picked up.
Thanks,
Ben YorkeWelcome to the discussions!
+"Not exactly a problem but just wondering if any ideas on how to get that speed back. "+ I don't have a good answer on this one.
+"Now i get the error -15000 message."+ This usually indicates that you need to update the firmware for the Express or that there is a security/firewall issue. See the attached Apple document:
http://support.apple.com/kb/TS2278
+"Now all it does is blink yellow and STILL doesnt get picked up."+
The firmware or security check above may fix this issue. If not,
the Express should be reset by holding in the reset button until the amber light blinks quickly. Open AirPort Utility and reconfigure the device. -
PLEASE HELP ME, Problems with airport/network set up all of a sudden.
Ok here goes. Saturday Aug. 19 I was on the internet, everythings fine. Then all of a sudden my airport drops/disconnects. I went into assistant, internet connect, preferences and so on. My computer tells me in Network Diagnostics that the airport is green, airport settings is green, network setting is green, isp is green, but internet and server are red. Ive messed around with it to no prevail, in fact I believe I think I have made it worse. Now only the airport is green. I have know idea. My roommate also has an Apple and his wireless/airport is fine, nothings changed. As I have "messed" with it, I have come across a section where it tells me my internet set up/preferences or something has been changed by another application, if that makes any sense. This is not so much a problem as it is a hassel. Now I must sit at the coffee table to get on the internet.
Is there a way to start over or is this a serious problem needing an Apple store tec? Can someone walk me through what I need to do to fix this, as I have no idea what Im doing.
If there is any more information needed... Please ask.No the password isn't your apple id password.
You encrypted your backup with a password, if you don't remember the password, then i'm sorry you won't be able to use it. -
Telephone interference with Airport network
I have read in several places both here and elsewhere that there is potential for interference by a 2.4 GHz cordless phone with my Airport network. Is it fair to assume that a 5.8 GHz cordless phone system would be okay? I am currently having no problems with Airport networking, and would like to keep it that way as I upgrade my old phone system.
Thanks in advance for any advice.That potential exists for any 802.11b or g wireless network as both use the same frequency spectrum. If you find a phone that uses a different spectrum, you should not have any problems. For example I have an old 900Mhz phone that does not interfere.
Good luck. -
Time Machine and "might be a problem with your network"
Hi! My Power Mac is from 2008, and I'm in the middle of replacing my hard drive. Here's a summary of what I've gone through, including various trouble shooting...
OK, the hard drive dies (all of which I wrote about in an earlier thread and, I think, not very relevant for this thread). While waiting to buy my replacement, I created an external bootable drive, hooked up via FW800. I created a new User Account, and then I used the Migration Assistant to bring in all the user settings, files, etc, from my Time Machine. It took many hours and and during the stage when it was transferring files, it gave me the prompt: "There might be a problem with your network. The other Mac is not responding. Make sure that all of your network devices are connected and turned on. Also, make sure that your Ethernet cables are still connected properly to your computer and to the network, or if using AirPort, that the base station is in range and turned on." After clicking "Continue" got me nowhere, I clicked Cancel, and it was a very incomplete migration [no apps, no files]. I didn't sweat this since this external drive is a temporary solution anyway.
Tonight I came home with the new internal drive, installed it, installed Leopard, and began the Setup Assistant. I got the same prompt as last night. NOTE: This time with Setup Assistant; last night was with Migration Assistant.
I notice from reviewing the boards that this Time Machine glitch seemed to happen a few years ago, in Leopard, and maybe hasn't happened since. But I haven't read a thread with a solution. (Maybe I missed it?)
A few things come to mind:
1. Could there be an issue with the fact that the computer is only 10.5 and many of the files/apps may have been installed when I was running 10.5.8? I'm just tossing that out there. For instance, what if I set up an initial User account, then updated the software to 10.5 and THEN used Migration Assistant to bring in the older account?
2. Soon, since I'm reinstalling Leopard, I'll get the prompt to use Setup Assistant, and this time I'll just select account settings and apps. I'll bring in the files manually, later. Since the progress window seems to get hung up during the file-transferring stage, maybe I'll have better luck if I skip that.
If anyone has any suggestions, man, I'd be way grateful!
Thanks!"try trashing the timemachine.plist in your original user's Library>Preferences."
I didn't even get to that step. Here's what happened.
I went back to my original Admin account (the one I restored via Setup Assistant, from my Time Machine backup), and ran Migration Assistant again. I selected Applications only and when it gave me a prompt about the account name already existing. So, I created a new account name (TEMP 1, I called it).
All of my applications were restored.
Next, I tried it with all the files and folders. It didn't give me the duplicate name prompt this time. It copied all my flles and folders over.
Was it perfect? Well, a lot of the apps need some fresh registration and some upgrading, but I suppose that's to be expected. Or is it?
While I feel like this problem is in my rear-view mirror, I'm still interested in your suggestons for a Time Machine altenative.
Thanks again for your advice! -

A lot of problems with my iPod(songs delet/stop at will)
I started my i pd up this morning and none of my podcast or music would play. After a while I just let my ipod sit and turned it on but it stopped after pleying about a minute. I reset the iPod and now everything is deleted. i am getting so fed up with this thing. I've had to reformat and reset it like twice in the last 3 weeks.

I've called up already and did a soft and hard reset. I am unable to send it in for repairs and they couldn't fix it at the store. I am very upset and either want a fix or I want to be able to trade it in for a new phone.
Hi Jaredk
3 and 5 are related, 1 and 2 may be part of that as well. The camera has terrible lag and all in all isn't that impressive but that's being addressed. I haven't had or heard any issues with the sound cutting out.
Have you tried going to Settings > Wireless & networks > Mobile networks > Network Mode and select CDMA Only to see if that fixes any of the issues you're seeing? Specifically the reboots and heat.
For the reboots I would recommend un-installing most of your apps and then slowly add them back until you notice the reboots start up. -
Problems with Airport setup after buying Version 7 models, (older ones will not upgrade)
Problems with Airport setup after buying Version 7 models, (older ones will not upgrade)
I re set up my Airport network , having had 4 expresses for years doing a good job. I bought another and an express, but then a time capsule after my external drive died. .Problems with Airport setup after buying Version 7 models, (older ones will not upgrade)
I moved house and have fibre network so 38mb/s - they all look ok on the utility, but its not till I saw the App version that they are not compatible as mac will not upgrade the version 6 ones, leaving me with 2 disjointed networks and 7 appliances, 4 of the old , 3 of the new.
my new house is expansive so i wanted the extended range and airplay in each room.
This is not told to customers, and utility doesnt show any issues.
I do not seem to get any range from either network now, - and I'm quite experienced with airport (6 yrs of setting up & using & extending)
Any advice ?

Big problem with Airport Extreme and Vivax Provider in Brazil
Hello guys.
I live in Brazil and I bought my Airport Extreme in a recent trip to USA.
For some years I was a client of Telefonica and had an ADSL link, I had a D'Link G604T to do both the modem and router operation in the same box. I was happy with my connection of 1Mbps.
In a recent promotion of Vivax I switched to a cable connection to have both TV and Internet at the same operator, my link now has 3Mbps.
With this pack I also received free one RCA cable modem model DCM425B, it was installed fine in one computer only. Everything was fine my connection was faster the old one.
So I went to install the Airport Extreme to make things even better.
After I installed I went to see the web status of my modem, all parts were looking fine, but the modem could not see the computer. Bad sign.
I talked to Vivax support people and apparently it was a problem with their network setup and they manage to make it right. My model now sees my computer.
After that problem was solved I could not make AE to work with the modem, it had the green light and the setup looked fine, but I could not open any site. I tried to turn off my modem and AE, waited some minutes and turned on first my modem and after it was up I turned on AE. All lights looked fine but again no connection to any site.
I called again the Vivax support center and they tried to help me but the don't know AE and they could not help me with all the details but said there was 2 10.x.x.x coming from my side. So I tried to use in bridge mode. I also selected the 192.x.x.x range instead of 10.x.x.x as default.
After many setups and turn off and on again my connection is working but I have a big problem with wireless. If I turn it on I loose my connection, it seems that AE sends 2 equal ethernet address to Vivax and their network don't like it cutting me off.
So my connection setup is like this:
RCA Cable modem model DCM425B at 3Mbps using a 200.x.x.x ip
Airport Extreme connected to a Mac and a Windows PC by wire using the 192.x.x.x range ip
Wireless is off
Bridge mode is on
This the only way I could make it work.After a firmware update it worked fine.

I move back and forth from school to home, and I've never had a problem with my card before. I recently restored my compuer back to its factory settings, and it was running great with my Airport Express. I came home after moving, and my computer won't read the WPA hooked up in my house. It says I am connected, but won't let me access the internet. I'm not sure why. We tried rebooting the connection, I've looked on my computer, used system preferences and everything. I did notice when I tried to use the Network Setup Assistant, it said the password I used to connect was wrong, but when my computer uses the airport icon at the corner of the screen, it accepts the password. Any ideas on how to fix this?
iBook G4 Mac OS X (10.3.9)An additional distressing note -- I went back to aforementioned building with the 10.4.5 Powerbook last night. Did a cold boot...and the Airport Express picked up the correct network DHCP info immediately. Roamed between a couple of WAPs, surfed a couple of sites, then sat down and tried to duplicate this feat...by re-booting at least 6 more times. Nada. I once again got factory default IP addresses on each attempted reboot. I changed nothing from the network settings I'd tried last week with this machine nor were any changes made to the network or WAPs. DHCP didn't work last week on several attempts (and reboots), worked ONCE yesterday on the first boot, then nothing again on the subsequent reboots.
Again, I'm stressing that there don't "seem" to be problems with the network or WAPs because Windows clients consistently obtain DHCP and authenticate without issue.
Does anyone have any ideas? -

I need advise and help with this problem .
First , I have been with Mac for many years ( 14 to be exact ) I do have some knowledge and understanding of Apple product .
At the present time I'm having lots of problems with the router so I was looking in to some info , and come across one web site regarding : port forwarding , IP addresses .
In my frustration , amongst lots of open web pages tutorials and other useless information , I come across innocent looking link and software to installed called Genieo , which suppose to help with any router .
Software ask for permission to install , and about 30 % in , my instinct was telling me , there is something not right . I stop installation . Delete everything , look for any
trace in Spotlight , Library . Nothing could be find .
Now , every time I open Safari , Firefox or Chrome , it will open in my home page , but when I start looking for something in steed of Google page , there is
''search.genieo.com'' page acting like a Google . I try again to get raid of this but I can not find solution .
With more research , again using genieo.com search eng. there is lots of articles and warnings . From that I learn do not use uninstall software , because doing this will install more things where it come from.
I do have AppleCare support but its to late to phone them , so maybe there some people with knowledge , how to get this of my computer
Any help is welcome , English is my learned language , you may notice this , so I'm not that quick with the respondGenieo definitely doesn't help with your router. It's just adware, and has no benefit to you at all. They scammed you so that they could display their ads on your computer.
To remove it, see:

Do not use the Genieo uninstaller! -
I ended up letting my itunes match subscription go because I was having a lot of problems with it. I was getting a lot of music where it would play the censored version instead of explicit like I have. After attempting numerous times to fix I gave up and let match expire. I had updated my library by downloading a number of AAC versions from itunes and then manually deleted all of them and added the proper files back by re-ripping my CD's again. I also added a bunch of new music and because I use a rating system, re organized all my music and rated some stuff with new ratings and higher star ratings.
About 3 months passed and I decided to give match another try. After getting it, I found it odd that my database was put there in virtually no time. Not only that, a significant amount of music I deleted (but was in the old match subscription) showed up. I knew it was broken at that point, but today, I was listening to music and items which I know have been updated and changed, have also reverted back to old settings. Is there a way to fix this?
Also, I'm REALLY annoyed with match again. After all my work, I STILL have censored music as my match music. It is really annoying to have different music on my computer than what is in the cloud (not to mention the music which will not upload to the cloud and just constantly says "waiting"!!)Yeah, and it didn't work.
I had problems when I updated to iOS 5 (lost all my apps - a few of my friends had the same problem) and when there was an update to iOS 4 (camera wouldn't work). The iOS 5 issue was sorted by backup (but I lost the app data) but for the iOS 4 issue I had to return my iPod to get a new one. -
Lots of problems with newer MacBook Pro
I bought my first Mac about a year and a half ago. Unfortunately I've had lots of problems with it. I need to get it repaired, but I'm not sure what's wrong. I live in Thailand so I want to have some idea of what's going on before taking it to a shop (so they don't try to price gouge me).
The first problem happened about 9 months after i bought it. The computer would become incredibly slow. Sometimes it would take 15 minutes to boot up and sometimes it wouldn't boot up at all. But sometimes it was fine. If it did boot up, sometimes when I'd go into a folder in Finder, nothing would show up. The spinning loader graphic would just spin at the bottom of the Finder window. I ran a disk check and it said it found multiple errors that could not be fixed. I erased the hard drive and reinstalled Lion and everything seemed fine. Since I live in Thailand and I need my computer for work, I didn't want to ship it off to Apple to be fixed. It seemed fine after formatting the hard drive, so I figured it was fixed.
About 3 months later the problem came back, but much worse. I couldn't boot up or anything. I took it to a small Mac repair shop because at this point the 1 year warranty had expired. Of course inside the shop it booted up fine and I had to explain to the guy that for 5 days I haven't even been able to turn it on. Finally after restarting 4 times it began slowing down and he could see what I was experiencing. He said he could try replacing the hard drive, but couldn't guarantee it would fix it. I needed my computer badly at this point so I said let's try. I came back a couple days later and he had transferred everything to the new hard drive and installed it. Everything seemed to be working fine.
That worked, although sometimes (rarely) something weird would happen, like the computer would just shut down for no reason. But, the DVD drive stopped working. It loads a disc OK, but it can't read it and won't burn a DVD. One time it wouldn't eject my DVD for about 30 minutes. I was trying everything I could find on Google. Finally it spit it out.
Now, about 6 months later, I was watching a movie and about 10 small colored boxes popped up on the screen. They went away after a few seconds, so I closed my movie and went to shut down my computer. The entire screen then filled with horizontal rainbow colored static. It stayed for about 30 seconds, then the screen turned grey. I could hear and feel the fans blowing at full speed.
And then for about a full day it went away, until earlier today. As I was backing up all my files I played a quick part of a movie. The same squares popped up on the screen so I immediately closed the movie and they went away.
I finished backing up and then erased the hard disk. I started installing Mountain Lion, and it stopped at about 75%. I canceled the installer and restarted. After a few seconds the screen turned solid blue with white staticky lines. And now that happens every time I turn on the computer after about 30 seconds. There's no operating system because before I can even get to the installer before the screen goes.
Sorry for the huge amount of info. I just don't have enough experience with Macs to know what's going on. My current issue resembles a video card problem, the issues before resemble a hard drive and DVD drive issue. Replacing the hard drive fixed it temporarily. Could a problem with the logic board cause all of these issues?
Thanks for any help with this.A few things to note...
If you had contacted Apple about each of the issues that you reported here, they would have kept a log of the problems that would help them determine whether to continue support after the warranty expires.
You might consider asking about "Flat Rate Repair Pricing." See the discussion thread here and note that some users report that the flat rate repair pricing is only available in the U.S. and Japan.

(typically they just ship your computer to Singapore instead of working on it "in-house" from what I read).
Actually, I had great experiences with two different macs sent to the repair depot. One computer had narcolepsy on day one. Apple sent me a box, I packed up the PB and dropped it off at UPS. Apple fixed and returned to my house two days later. The second MBP had a known video card problem. I took it to an Apple Store Genius who ran a specifc test and deduct that it was the known defective video card. The store was out of parts and ordering would take a week. Knowing my past experience with the Repair Depot, I ask for that option. The genius took my MBP and shipped it to the depot that night. Three days later, I received the fixed MBP and on the work order, their tests showed failed fans that they also replaced. Three or four weeks later, the Apple Store called to tell me they got the video card in stock.
Gather up your grit, perseverance, and persistence before contacting Apple. Try bypassing phone support by contacting them via their online support system with the link I provided in the previous post. (I remember using the online support system and was able to choose to have them call me. At the time, I had AppleCare so i'm not certain with out-of-warranty.) Another option is to seek an authorized Apple service provider.
Good Luck! -
Guys,
I really am having a lot of problems with a program. I got the program to compile but it looks absolutely nothing like it is supposed to look. I have a deadline for tomorrow and sent my teacher an email but the chances of him getting back to me by tomorrow night for a weekend is pretty much slim to none.

g. a Clear button
h. a Panel to hold the 3 TextFields, 3 Labels, and the 2 Buttons
3. Create a constructor method to:
a. construct each of the components declared above and initializes the start, stop, and step variables to zero (when constructing the TextArea components, use the following parameters: null, 3, 5, 3)
b. set the Frame layout to BorderLayout
c. write a for loop to loop the array and set each of the 16 TextArea components in that array so they cannot be edited. In the same loop, set each of the TextArea components text to be 1 more than the index number. Also in this same loop, set the background of each of the TextArea components to white.
d. set the Panel for the TextArea components to GridLayout with 4 rows, 4 columns, and both gaps set to 10
e. set the Panel for the TextFields, Labels, and button to GridLayout with 3 rows, 3 columns, and both gaps set to 5
f. add the components to their respective Panels
g. make the buttons clickable
h. place the Panels in the Frame� put one in the NORTH and one in the CENTER
i. Enter the addWindowListener() method described in the chapter� this is the method that overrides the click of the X so it terminates the application
4. In your actionPerformed() method:
a. convert the data in your TextFields to int and store them in the variables declared above
b. write a loop that goes through the array setting every background color to blue
c. write another loop that�s based on the user inputs. Each time the loop is executed, change the background color to yellow (so� start your loop at the user�s specified starting condition. You�ll stop at the user�s specified stopping value. You�ll change the fields to yellow every time you increment your loop based on the step value. REMEMBER: Your displayed values are 1 off from your index numbers!!)
5. Write a main() method that creates an instance of the Checkerboard Frame.
a. set the bounds for the frame to 50, 100, 300, 400
b. set the title bar caption to Checkerboard Array
c. use the setVisible() method to display the application Frame during execution
6. After you get all of this complete, include error handling to make sure:
a. the values entered in the TextFields are valid integers
b. the start value is greater than or equal to 1 and less than or equal to 16
c. the stop value is greater than or equal to 1 and less than or equal to 16
d. the step value is greater than or equal to 1 and less than or equal to 16
e. the start condition is less than the stop condition
f. when an error occurs, give an error message in a dialog box that is specific to their error, remove the text from the invalid field, and put the cursor in that field so the user has a chance to re-enter� this can be accomplished by using multiple try/catch statements
g. only change the colors if the numbers are valid
7. Create a clear button as seen in the example below. This button should:
a. clear out all 3 TextFields
b. change the background color of all TextArea array elements to white
c. put the cursor in the start field
8. Document!!
I know you guys are probably busy with your own stuff but any help and I would certainly appreciate itgot the yellow boxes to come up but just one box.....so is there something wrong with my yellow set background because I am not seeing any more errors
