Dual networks, express and extreme problem with Intel iMac accessing both

I have two airport networks setup to two different ISP's. One is setup using two Airport Expresses with a printer hung off one. The other is setup with an Airport Extreme with two USB disks.
I have a G4 iBook 14" laptop and a MacPro 17" Intel laptop that see and can bee switched between both networks utilizing Internet Connect. They are running OS X 10.4.11.
The other system is an Intel iMac 20" (late 2006) running OS X 10.5.1. The only wireless network it sees is the Airport Extreme. This is frustrating because I want to be able to switch to the Express network to print and cannot get the iMac to recognize the network. Before upgrading to 10.5.1, I could, on occasion, see the other network, now I can not.
Has anyone experienced this and is there a way to fix it? I believe it is operating in 802.11n, but have no way to verify this.

I miss posted this in windows. I reposted this in the Airport Extreme.

HP Color LaserJet Problems with intel iMac

Can anyone give me advice on the following:-
When I try to print from my wife's new intel iMac 20" to our HP Color LaserJet 2550L, it doesn't work and print center gives me the following error message ... "The process "hppostprocessing" terminated unexpectedly on signal 5" .
The printer is connected directly to the iMac via USB. It's not on a network.
I ran the HP Color LaserJet installer from the original CD that came with the printer and when that didn't work I downloaded another (latest) Color LaserJet installer (dated 2004) from the HP website. Still getting the same error message from PrintCenter.
When I look at the HP installer log, it appears that the installer tried several times without success to install plugins into the PPD folder (HD->Library->Printers->PPD).
After trying installation and checking out my PPD folder (above) there is nothing in it.
This printer has been (still) working fine with our older 20inch iMac.
Any advice or suggestions would be appreciated.

Same happened with my photosnart. Here is part of the email from HP
Thank you for contacting HP Total Care.
I understand from your email that you are not able to print to your
photosmart 1218 printer from your new imac.
I believe you are correct when you mention the glitch between the new
Intel processor in the iMac.
I have checked the Apple website and noted the pre-installed printer
drivers that ship with this operating system, do NOT include drivers for
the Photosmart 1218 printer. There are Gimp print drivers available for
the Photosmart P1000 printer. They may work, but provide only basic
printer functionality. (see the Apple document listed below).
http://docs.info.apple.com/article.html?artnum=303057#hpdrivers
I understand that our engineers are investigating the driver issue with
the Intel-based Macs, however, I cannot provide you with an expected
date of resolution. Your printer was manufactured in 2000, and the most
recent drivers are from Aug 2005. These drivers were created before the
Intel based macs were available.

Gameplay problems with Intel iMac

I have an Intel iMac with 2GB RAM and the 256MB graphics card. Despite this equipment spec, in playing Medal of Honor Allied Assault, I often experience some lag/framerate problems - in the "Day of the Tiger" opening mission, the game runs so slooooooowly that I become a standing target. What's up with this?!? Is it a Rosetta issue? Seems to me that with the hardware I have, it should run flawlessly, Rosetta or no Rosetta.

Yeah, just tried lowering the game settings so far that it looks like it's being played on an old 386 PC...and the @$% thing *STILL* freezes up solid in the first 30 seconds of the initial "Day of the Tiger" mission. The lag problems in the earlier missions were annoying, but not serious enough to necessitate lowering the graphics to cartoon level, or to disrupt frame rates to the point where the game is literally unplayable. I've already submitted a 2-star review for MOHAA on the Apple Store, so hopefully my experience will inform others...
Any recommendations re a WW2 themed 1st person shooter that actually WORKS on our machines?!?

Serious Problem with intel iMac

I have an Intel iMac 17" Core 2 Duo 2Ghz, purchased in February of this year. I installed printer drivers for the Canon MP130, and it told me to restart, which I did. When I restated, the computer chimed and is stuck on a gray screen (not even the apple logo). It can be turned off by quickly pressing the power button, not even holding it. I have tried various boot up keys - single user mode, reset PRAM, but none work - I'm guessing the computer hasn't booted up far enough. I can get the restore disk, but I'd like to avoid that if possible. Is there anything I can do to rescue it?

Did you try running the hardware test from the OSX install CD? If all else fails you might try backing up your important data and doing an erase and install of OSX.

HT1515 Do the Airport Express and Extreme work with PoE switches? I.e. can they 'receive' power from PoE switches?

Hi,
I've just bought an Airport Extreme and an Express, running 5Ghz/2,4Ghz and it works well.... However, to be able to place the devices more optimally I'm wondering whether they support power over ethernet (PoE)?
Thanks in advance for your help!
Kr, Rudy

The AirPorts do not support PoE.

Dual Boot Linux and Windows problem with HDDRecovery

Hello
I`m using dual OS Windows Vista and Linux open SUSE distribution on Toshiba Satellite A350-10z, everything is working great except Windows Recovery. I have Linux (boot:dev/sda6) and Windows Vista (boot:dev/sda2). Windows has 2 partitions, Disk C and D, on Disc D i have HDDRecovery folder. After F8 i using the repair option and waiting, then the massage is displayed "The installed program cannot start. Click OK to turn off the computer".
Before i installed Linux the Recovery worked fine. Is there a chance of using the HDDRecovery from Windows Disk D or i have to boot from Recovery DVD?

In my opinion Linux has muddled up the partitions or MBR and possibly this is the reason why the HDD recover does not work seems the Recover DVD is your option ion order to set the notebook back to factory settings.
By the way: I didnt install the Linux on my notebook but I use Linux using the Knoppix Live CD

Performance and instability trouble with intel iMac after 10.4.8

Hi all,
I have a 20" intel (Core Duo) iMac. Everything was super fast and nice since I bought it last February.
I recently "software updated" to 10.4.8 and since then it seems slower, groggy, and Safari crashes regularly.
Is this a known issue or is it just me? Is there anyway to uninstall 10.4.8? Or, can anyone recommend a utility to help diagnose the problem?
boxlight

Hi boxlight,
No, you are not the first to mention the issues you are now experiencing with the 10.4.8 update...
Here's what I would try: http://www.apple.com/support/downloads/macosx1048comboupdateintel.html - you can run the Combo Update and see if that "fixes" any issues. There have been posts re: using the Combo Update which ended up fixing some software glitches...
You can also go here: http://www.thexlab.com/faqs/maintscripts.html#Anchor-Manually-49575 - I use the Terminal method to run the Maintenance Scripts and my Mac runs better than new...
Good luck, Rick

Having a huge DoS problem with Intel IMac. Help!!!

I am suffering from a hugely debilitating DoS attack that seizes control of hardware devices, installs bogus versions of files and executables, prohibits the installation of more sophisticated firewall and antivirus software by spinning down the DVD drive until the install program croaks. This is as malevolent a hack as I have ever seen,,, Erasing the disk from the 6.7 Install DVD leaves read-only files on the root, and the sudo command from terminal has been either moved or deleted so I cannot modify the files via chmod, chflags or rms commands...sigh I have tried to use TechTool, Drive Genius and various other disk management utilities, but they are ineffective at deleting this read-only volume. Additionally, when I tried to use my external firewire drive containing my Time Machine Backups, the backups had all been deleted - I assure you not by me!!! bummer..... HELP!!!!

Try starting your iMac with the original DVD that came with your computer (you can still use the terminal), The best thing to do is format your drive and reinstall, but I see you don't have a current Time Machine backup. Use disk utility on your Time Machine drive to try and repair it, also repair your permissions, http://support.apple.com/kb/HT1782

Problems with Airport Express and Extreme

I have tried to set up Airport Express and Extreme. Both proceeded normally in the Air Port Utility until the final stages. Then it said it couldn't find the devices. When I tried again (many times), I couldn't even start the process, even though it did that the first time for both. I'm stumped.

To set up the 802.11n AirPort Extreme Base Station (AEBSn) as a bridge, either connect to the AEBSn's wireless network or temporarily connect your computer directly (using an Ethernet cable) to one of the LAN port of the AEBSn, and then, using the AirPort Utility, make these settings:
AirPort Utility > Select the AEBSn > Manual Setup > Internet > Internet Connection tab
Connection Sharing: Off (Bridge Mode)
Click Update to apply the new settings
AirPort Express Base Station (AX) - iTunes Setup
Either connect to the AX's wireless network or connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, make the following changes:
AirPort Utility > Select the AX > Manual Setup > AirPort > Wireless
Wireless Mode: Join a wireless network
Network Name: <existing AEBSn's wireless network>
Wireless Security: <select the encryption type of the existing wireless network>
Wireless Password: <enter the existing wireless network password>
Verify Password: <re-enter the existing wireless network password>
AirPort Utility > Select the AX > Manual Setup >Music
Enable AirPlay (checked)
iTunes Speaker Name: <enter desired speaker name>
iTunes Speaker Password: (optional)
Verify Password: (optional)
Click Update to write the new settings to the AX

Airport Admin loses Express and Extreme, no iTunes, no Network Printer

Ever since I have upgraded to Tiger, I’ve experienced a strange, random Airport Extreme/Express problem which I have not been able to solve. I can sometimes replicate the problem but never consistently.
Laptop Configuration: 15” Powerbook G4 running Mac OS Tiger 10.4.3 with most current patches. System is stable and manifests no problems.
Airport Network Configuration: Network is closed with 128bit WEP encryption. No other laptops attached to the network besides my Powerbook.
Base Station: Airport Express attached to DSL modem with “Distribute IP Addresses” checkbox enabled, running firmware v6.2, stereo speakers plugged into audio jack. Network access is restricted by MAC address; RADIUS not in use, default IP address scheme is used.
Remote Base Station: Airport Extreme running firmware v5.6. The Extreme hosts a HP 1012 LaserJet printer plugged into the USB port and an IP phone plugged into the LAN port.
The Express and Extreme are within 15 feet of each other and enjoy a clear, strong 802.11b/g wireless signal on Channel 1 with a multicast setting of 11, interface robustness enabled and transmit power set to 100%.
Symptoms: iTunes loses its remote speakers setting; I cannot print to the network printer attached via USB to Airport Extreme; Airport Extreme and Express do not appear in Airport Admin Utility….yet I can access the network via the Powerbook, I have full internet access and IP phone can make calls. I just can’t print to the network printer or use AirTunes.
Troubleshooting: I can restore all functionality if I perform a hard reset of the Airport Express Base Station then re-import my saved Airport Express base station configuration settings. I typically look at the Airport Admin Utility to determine if functionality has been restored. If both the Airport Express and Extreme appear in the Admin utility, all is well. If they are not there, sometimes a laptop reboot will restore them, other times they will not appear when the Admin Utility is opened or when I rescan. If a rescan fails, I can access the Express and Extreme by typing in the IP address and password. Then each will show up in the Admin Utility and I can make changes and restart the devices. Even with a device restart, they will not automatically appear in the Admin Utility.
I first thought the problem was associated with the laptop going to sleep but this is not the case. Sometimes when I reset the Base Station, re-import the configs and reboot the laptop, I am able to automatically see the Express and Extreme in the Airport Admin Utility. Other times I can’t. Sometimes my settings will last a few days and I’ll enjoy full functionality then they will disappear. Other times they will disappear immediately, even with a reboot and a reset of the Express and Extreme.
If I use a 3rd party utility called Cocktail and reboot, I can restore functionality. Cocktail will delete all user, system and kernel caches, delete all log files, rerun disk permissions, and run the daily, weekly and monthly Apple Kron maintenance scripts. If I reboot after running Cocktail, my Airport Extreme and Express appear in the Admin Utility. Thus, I think the problem may be associated with a Airport Extreme cache file becoming corrupted or deleted upon reboot…….but I am not positive.
If there are any Airport experts out there, let me know what you think. I love Apple, I love my Mac and my little Airport Network…….but this is ******’ me off! Thus my plea for advanced geekery review and assistance.
Talk to me!

If the Airport Admin Utility cannot automatically "see" your Base Station, you have a big clue as to the cause of your problems. On a private LAN, it should never be necessary to select "Other" and manually type in the Base Station's IP address.
The most likely cause for the Airport Admin Utility not being able to automatically "see" an Airport Base Station - is a firewall on the Mac that is blocking it. Any of the following are possible:
- you have installed non-Apple firewall software on the Mac
- you have installed so-called "internet protection" software on the Mac
- you have installed "internet monitoring" software on the Mac (like "Little Snitch")
- you have installed VPN client software on the Mac - and many of these applications install their own firewall
All this stuff needs to go, since it will cause all sorts of trouble with communication between a Base Station or Airport Express, and a Mac.
I'd also be very worried about what this "Cocktail" utility is really doing to your system.

Interference with my Express and Extreme?

I have an Airport Extreme purchased several years ago to connect two iMacs. We have updated each computer, one is a newer iMac and the other is a MacBookPro (06). We have had trouble getting a signal to reach both computers since we first bought the Extreme. I added an Express and it seemed to solve the problem.
The Extreme is located next to the desktop computer. My laptop (which is never further than 40 feet), randomly gets dropped offline. I have to go through choosing airport, my network, etc, each time I'm dropped and each time I boot up. I never had to do this before. The only change I made recently was password protecting my network. I have done software updates since the problem started and also have run firmware and software diagnostic tests which were fine.
I've been to the Genius Bar three times, I've spoken with Apple Tech support for over 3 hours total on this issue. The Extreme tested fine in the Apple Store, I purchased a new Express and the problem is worse. When I get connected it will sometimes work 20 minutes, an hour, or 5 minutes. When this happens I have to sit right next to the Extreme to pick up a signal.
We have single wall construction, no cordless phones and I can't think of any other interference. Sorry this is so long but I'm desperate! Thank you

Hmmm. That can make a difference, but I would think that should be exhibited as a performance hit as opposed to a reliability problem. Early AirPort Extremes took a hit with WEP (according to http://www.smallnetbuilder.com/content/view/30664/228/). After looking at iStumbler, there's an old (2004) but good article at http://www.smallnetbuilder.com/content/view/24311/98/ covering a/b/g nets; for instance, make sure your SSID is unique. Also, if running 802.11n, take a look at this article at http://www.smallnetbuilder.com/content/view/30664/228/ (esp. Fixes #4 and #5).
I found running 802.11n to be futile around here (well, it is Silicon Valley). [iStumbler] will give you a clue about things in your area, but I found that the local WiFi environment changed day-to-day as new nets came online, or folks changed the bands they're using and/or switched to using wide channels (channel bonding). I could never stabilize things for more than a day or two here, so ended up buying a new Extreme and running Radio Mode = 5 GHz only - the only one in the area (at the time). That helped lots.

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. any soln ?

I have bought a new airport express and using it with my macbook (iTunes 10.2.2). I have joined an existing wireless network for internet in my home and with that i am trying to play the music via itunes but there is audio dropouts every 60 secs or so. I am using a set of speakers from kenwood connected to the airport express. The operating system on my macbook is mac os X 10.5.8. i am sure it is not a problem of streaming music online because i have even tried playing music which are stored in my macbook.
Is there any problem with the setting in itunes or quicktime ? Kindly reply...... I am waiting for your valuable suggestion.
Thank you a lot in advance.

I am shocked to have found this same AX audio dropout problem starting TODAY, every few seconds the audio just drops for a couple seconds and then resumes: Latest software versions of everything. No iPad, iPhone or Touch. Internet hardwired to D-Link DES1105 (1000baseT Switch) hardwired to new 80211N AX, AX optical to stereo, AX Wi-Fi internet to basic 1st-gen MacBook operating at 80211G, and an older 'G' AX extender at the far end of the house, away from all this. The MacBook streaming iTunes is usually 12 feet from AX. I've used this setup for years of trouble-free AirTunes / Airplay until today. Today I also found 2 very reliable fixes and 1 way to force a dropout, but first, I read some posts and tried ALL following settings one-at-a-time and restored them ALL because NONE of them helped: Turned off IPV6. Streamed to multiple speakers 'Computer' and 'AX' (restored to just AX). Turned off 'Ask to Join new (WiFi) Networks'. Turned off Bluetooth (can't live without Magic Trackpad, so glad that wasn't it). Here's my discoveries: Lo and behold, each time I click the Airport icon in the Menu (you know it shows you've got 4 bars from AX) when the status switches to 'Looking for Networks' for a second it CAUSES the AX audio to drop out for a couple seconds (it never did that before today.) iTunes still playing, streaming, AX laser still lit, but the 'PCM' light on stereo and the sound GOES OUT EVERY time I click the Airport icon in the menubar, just like the regular, annoying dropouts. So, to reduce traffic I quit Safari (3 tabs, no streaming, just Gmail, Google, and Netflix browsing). Lo and behold, the dropouts stopped altogether. No other Web apps going (not iTunes Store, Genius, Ping, nothing), so I launched Chrome to the same 3 tabs and the dropouts HAVE NOT RETURNED. That's right, not only did simply QUITTING SAFARI cure it, and Chrome doesn't contribute to it, but I can demonstrate it just by forcing my Airport to re-scan. Works for me, written using Chrome. The other reliable fix is to hardwire MacBook to the Switch. This is obviously not ideal, but Airplay audio doesn't drop out over Ethernet. Also, in all my tests, it made no difference whether iTunes did the streaming, or Airfoil did.

I changed my Airport Extreme network name and password, now I can't access my Airport Express speakers. Help please.

I changed the network name and password associated with my Airport Extreme and now my system is not recognizing my Airport Express speakers.
Can someone help me get my speakers and sound system back online?
Thanks in advance for any assistance.

You will need to think in reverse here.
Change the network name and password back to where it was on the AirPort Extreme and get things working that way.
Then, change the name and password on one AirPort Express, then the second. Both Expresses will be blinking amber at this time. Power them off.
Now, change the name and password on the AirPort Extreme.
Power up both Expresses and they will now join the AirPort Extreme network correctly since you have programmed them with the new network name and password.

I have a tesco router and an external hard drive attached to it as a network drive (shared) for my macbook and MB-Air. Have no problems with my MB accessing it, but with MB-AIR it says - 'the version of the server you are trying to connect to is not supported. pls contact your system administrator to resolve the problem'. MB-Air uses maverick downloaded yesterday - upgrade from mountain lion. MB uses snow leopard still, as i am quite used to it and am thinking of upgrade if mavericks work fine on air. Also have parallel on snow leopard but it is no longer supported according to mac website - if i upgrade am i going to lose my parallel and will have to buy a new one!!!

Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think?

Success with iDefrag and DiskWarrior on my Intel iMac! (indirectly)

Had some very good success using iDefrag and DiskWarrior on my intel iMac, both of which do not run directly on the intel platform yet. As I had observed a gradual (modest) slow-down over the course of the past month since I got my iMac, I couldn't help but try to figure out a way to defrag and optimize the hard drive since I had over 125GB (including quite a few large media files, and a couple system updates, both of which tend to cause fragmentation). So, after doing two independent backups on separate external HD's, I ran iDefrag on my iBook and defrag/optimized the iMac's hard drive using Target Disk Mode. As expected, the hd was VERY fragmented - and the process took overnight to complete. Being as careful as possible to ensure no problems, I then ran verify disk and repair permissions on the iMac's hard drive, and no problem. Did notice a very meaningful increase in responsiveness and speed on the iMac, even more than I would have expected. Since I historically always ran DiskWarrior after doing this exercise on my PPC mac's, I decided to attempt the same here. Since I (and others on this board) have been unsuccessful in running DW3.03 using the iMac in Target Disk Mode, I decided to update backup drive #1 post-iDefrag, and was then able to mount this drive (backup#1) and run DiskWarrior on it from the iBook. No problems were detected which was great news, but the I had it write the new index/directory files. I then sync'd back to my iMac's hard drive (from backup#1 to iMac HD) and observed that a number of files were updated most likely as a result of the updated directory/index files from running DW (I use FolderSynchronizer to sync). So keeping backup#2 of the pre-iDefrag/DiskWarrior for a while, but so far so good, and a very meaningful improvement in performance. So the experiment seems to be a success.
DISLAIMERS: If anyone does "try this at home" please backup and re-backup before attempting. In addition, please note that Coriolis is in the process of developing an intel build for iDefrag and probably recommended in general to wait for this update.
iMac 20" 2GHz Core Duo 2GB RAM, iBook 12" 1.33GHz Mac OS X (10.4.5)

Thanks for this posting and the good advice. I put in some time chasing the 801.57 gb limit before finding this thread that steers in the direction I see now I must persue, a new enclosure (modern day version rather than 5 year old technology -- yes, the old external drive has the Oxford chipset mentioned repeatedly in other threads) to go with my new drive. Would have been better off $$-wise to have purchased a complete unit, but this is so much more fun on a Monday evening.
Great being here with you all!
