New iMac, 24" 3.06 Ghz - WIRED Connection Problem

Hi All - This machine has been in service 2 weeks. About a week ago, the connectivity to the internet has become faulty. I can successfully connect to a web site, but after about a minute or so, it will drop. Using the same browsers and MacOS on a MacBook Pro, there are no problems. I have disabled and made inactive, all network options except for ethernet. Still to no avail...
Suggestions are most welcome.
I saw a suggestion on a post concerning junky wireless connections to re-install the os to an earlier version, and may reluctantly try that.
This is a true disappointment.

The only way we will see this problem resolved is for everyone having the problem to call Apple Care and get this problem elevated. With all the posts on this forum concerning this issue I was surprised that the techs at Apple I spoke with were not aware of any widespread wifi issues with the iMac.

Brand New iMac 24" 2.8 GHz Intel 2 Core Extreme 500 GB Hard Drive Issues

Had a 2 week old iMac 20" 2.4 GHz 320 GB hard drive that I purchased from the Apple Store online on 12/09/07. Got delivered to me on 12/13/07. After 7 calls (on 7 different days) to Apple Care Support, my iMac could not get onto the internet network in my apartment.
Had Apple swap my unit and I got the top of the line model out there now, the iMac 24" 2.8 GHz Intel 2 Core Duo Extreme with 500 GB hard drive. Still, can't connect to the internet.
I've got Time Warner Cable as my internet service provider (High Speed Internet Access). I'm using a brand new Airport Extreme as my base station in the living room, and a brand new (all exchanged through AppleCare) Airport Express which I'm using to extend the network as a bridge.
My new iMac is in the study den in my apartment, and my MacBook Pro gets signal from anywhere in the apartment, but when I use the iMac, and click on my secure network using the WPA2 passcode that I set up, the iMac tries to connect, and says "Connection Time Out" and then "Connection Fail."
I've read posts throughout these forums saying that there are issues with the new aluminum iMacs that came out.
I'm running Leopard 10.5.1 on both machines right now, and even with the swap from the 20" to the 24", I still have the same problems.
Gonna have to make another angry call to AppleCare Support tonight to see if I can get this thing resolved.
Anyone else have any other suggestions to getting this fixed for my iMac?
What about using a different router besides the Apple Extreme or Airport Express? Any ideas?
Thanks

ok try this with your MAC BOOK PRO
Go to your system preferences go to the apple icon and then hit system preferences. From section where it says Internet & Network, there you should see an icon folder that says Sharing, In tiger its like that I don´t know how it is in Leopard, but if it is the same we are in luck. Ok Go to sharing and in sharing go to airport option in airport option make a 128 bit wep key and make a sick *** long password hit ok. Now go check the box that says Airport and then hit the start button to start using your MAC BOOK PRO as a router. Now go to your sick *** I wish I had your 24 inch Imac and here I am stuck with my old Imac early intel, and hit the airport extreme icon oh by the way you should also enable your MAC BOOK PRO airport extreme which now it is a WIFI Router trasmitter I Hope I was of any help

New iMac can't see Laserwriter Select connected to a PC on same LAN-- why?

I've just returned to the Mac universe after a five year hiatus. When I discovered how well Macs play with PCs and Unix these days, I decided to come back.
There's just one issue: I can't print to my Laserwriter Select 360, connected by parallel port to a Windows XP Pro PC on my LAN. My new iMac doesn't see the printer at all. The imac does see the PC's workgroup in the Network Neighborhood, and I can mount the shared volumes of that PC on the mac with no problem, so the Mac can talk to the PC for filesharing, anyway. (smb:// address used)
Applecare has no clue why I can't see the printer. They told me to turn on Windows Sharing and Print Sharing, but that had no effect. The Windows machines on my LAN can all see and print to the shared Laserwriter Select 360, no problem. They're all running Windows XP pro, latest patches.
The iMac of course has the latest Tiger. All machines are on my internal subnet 192.168.0.*.
I just got a new cartridge for the Laserwriter, and there's no reason to retire it-- that printer works great. I just can't believe/accept that the iMac can't be made to print to an Apple printer! (Also, I've heard that appletalk->ethernet bridge solutions are flaky so that's not an ideal route).
Any/all ideas welcome.
imac g5 Mac OS X (10.4.3)

Here's the result. The PC is on 192.168.0.2, and the iMac was assigned .18 by DHCP.
I just tried adding a lexmark printer to the PC (over USB) to see if there might be some difference. The other windows box on the lan sees the LexMark same as it sees the Laserwriter (and both show up in the output of smbclient below). Needless to say, the iMac doesn't see the LexMark either.
Thanks for your help with this one...

New iMac cannot hold a FW 800 connection

Hello all, I have this brand new iMac for my music studio. This machine cannot hold a FW connection for more than a few minutes without losing it. Because there is only one FW 800 port (boo!! I cannot grasp this move by Apple to kill off it's association with pro audio apps and studios that have so much invested in FW 400..anyway...), grr..because of the one 800 port, my signal chain is first to the Apogee Ensemble via a 800 to 400 converter cable, and then to two outboard PPA Oxford 911+ chipset 500GB drives. When the FW connection fails, the only option is to shutdown the whole shebang, drag the hard disk icons to the trash which BTW, is not reliable on this machine for some reason, shut down the Ensemble and restart it, remount the drives, etc.
C'mon! Apple! Are you listening? Why can't you make a computer that can be used in a recording environment without one stupid FW buss problem after another? It was like this with the Lucent chips, now it's another problem! Do you have no interest in pro audio anymore?
I have been browsing this board. My other posts are on the Logic Express board, which is full of posts by me and others wondering about the FW problems. This is a new machine, same FW buss problems, may or may not be chip related. Very frustrating. Cannot refresh connections without restarting. If anybody's got any insight on this, I'm all ears.

These are the formal procedures for PRAM reset and SMC reset, so be sure to do them precisely.
http://support.apple.com/kb/HT1379
http://support.apple.com/kb/HT3964
You seem to have a lot or peripheral devices. When you reconnect from doing the SMC reset, if you are using a power strip that is old or crowded with other devices, for this test, you should plug in the iMac directly to a wall power outlet. If your FireWire devices are on one power strip, you should also spread them out to more than one wall outlet.
Connect one FireWire device at a time. See if this problem exists if only one device is connect; use one at a time to check if the FireWire connection remains stable.
If each device checks out by itself, connect that "Apogee Ensemble" first, and daisy-chain one of the two FireWire drives to see if it remains stable. If so, remove that device and try the other FireWire drive.
Finally, if all is well with two devices connected, try them all connected at the same time.
Note: If one or both of those FireWire drives is being used for a function that does not require the faster FireWire speed, and the drive also has a USB 2.0 interface, you should connect it via USB 2.0. For example, a Time Machine backup drive does not require ultra fast data access. USB 2.0 is more than fast enough. So take some load off the FireWire port and use USB 2.0 when possible.

Final cut studio 2 on new imac 24'' 2.8 GHz

Hi,
I am, in the near future, starting wedding videography and my idea is to purchase Final Cut Studio 2 and the new imac 24" 2.8GHz with 4gb RAM and the 1TB hard drive.
My question is this, will this computer be powerful enough for me to run the Final Cut Studio "smoothly" while editing HD quality video?
My business will be based on this so i want to be sure!!!
Thanks in advance!

I am, in the near future, < </div>
How do you communicate with us then?
Do not start your business based on a computer and a piece of software. Research the business first, then decide what you will need and then figure out a way to finance it. When you get down to starting your event photography business, the computer is going to be the smallest captial investment you make; do not scrimp on it.
The iMac will only satisfy your needs for a few months but it will do the job. You must also have printers, scanners, backup routines and external drives. Umm, insurance.

New iMac 24'' 3,06 GHz

I used to either ask question on Apple discussions or indeed sometime though rarely complain.
Today, I am simply thankful. It has been one day with my new iMac and it is awesome.
Just wanted to share some good news.

You're like a bright ray of sunshine! If you do need help in the future, you know where to come.
And congrats on your new iMac.

Windows 8.1 wired connection problem

My computer with Windows 8.1 started to lose internet connection very often (about every minute). I tried to update drivers for network card, even bought new network card with no result. Also, tried to connect directly without router and connection
still drops. Network troubleshooting did not find any problems, no errors are displaying. What may be causing the problem?

Hi,
Wired connection, have you checked the cable? Please make sure that it's functioning fine.
You can also test the connection with another PC to find out whether the culprit is your own PC or the ISP.

Wired Connection problem on Officejet Pro 8500 a909a

I am having what seems to be to be a strange problem.
I have lost connectivity to my printer (Officejet Pro 8500 a909a) through the network from my Windows 7 64bit computer. I found that it worked fine if I connect throught he USB port. Today, I have been trying to get back to being able to use it through the network.
I am able to get to the configuration on the printer through the network, at http://192.168.0.105 and that works fine.
I have downloaded the most recent software and when I run it, it doesn't detect the printer, even if I enter the ip address in the advanced search box.
I have downloaded the HP Print and Scan Doctor, and when it runs, I can see the printer, however i'm not sure why it shows 2 lines:
When I choose the last line and press next, all it does is goes to this page:
Your help is appreciated.

What operating system does the computer use?
What happens when you choose the network-wired option on that last screen? Since the printer is already installed, the software thinks you are wanting to install the printer again and presents the last screen.
Your printer is listed twice with two separate IP addresses. I suspect the issue may be that the IP address is changing to frequently for the detection protocol to keep up with it.
If the printer is on the network and you can access it by entering the printer's IP address in a web browser, you can try setting a static IP address for the wired connection. Click on the Printer Does Not Maintain Wireless Connection document from HP. The document is for wireless connections, but the same steps can be applied for a wired connection by substituting wired for any section that designates going to the wireless section of the printer.

New iMac with existing iPod Touch (64G) authorization problem

I got a new iMac and transferred everything over to it from my existing iMac using the migration assistant during the first boot-up. When I sync my existing iPod touch (64G 3rd gen) I get stuck in an authorization loop where the Mac says I need to authorize the computer, I do so and then it says the computer is already authorized. New CDs that I have imported into my iTunes library since I bought the new iMac will not load onto the Touch during sync and some (but not all) of the music that I have purchased from iTunes will not play on the iMac. I have already checked to make sure that I have all the recent software updates and I do.
Any idea what is going on and how to solve this frustrating problem?

Deauthorizing and reauthorizing my Mac solved the problem with not being able to sync newly imported CDs with my iPod Touch.
The problem with not being able to access some of my purchased iTunes music is a function of having 2 different iTunes accounts that I bought tunes with. I'll need to contact apple customer service to sort that one out.

Difference between new iMac processors 3.5 GHz Quad i5 vs 4.0 GHz Quad i7

The only major software I use is Aperture and Photo Elements.
I have Bento about 7000 entries.
I am retired, no business app.
I am one of those that believe get the top of the line it will last an extra year or 2 of viable usage .
My current iMac is:
2008, 3.06 GHz Core 2 Duo with 4GB 800 MHz DDR2 SDRAM, NVIDIA GeForce 8800 GS 512 MB
Any thoughts ?
Thanks
Greg

The Flash drive will provide faster access to data, but does not directly affect the processor.
If you don't need the extra space, then go for the smaller Flash drive to keep data access times at their peek.
As to the difference between an i5 and i7 obviously the processor speed is one. But buffer, and cache and other specs that will aid in performance may be different.
If money is no object go top of the line. Otherwise the i5 should work fine for what you want to do, and will be a marked improvement over what you have now.

AE Base Station wired connection problem..

Okay..
I have cable internet hooked up like so:
Modem --> Airport Extreme Basestation extended by 2 AE expresses...
I use the LAN port on the AE basestation to route internet to the hardwired computer.. This has worked well until recently... I recently recieved a new cable modem that work fine when the desktop comp is hooked directly to it. When I try hooking it up to the base station this is what happens:
the airport signal will be great.. all wifi users can surf and connect to the network. The wired computer will work for about 30 mins or so then will stop recieving signal. The only way to get it to regain internet is to reset the cable modem... The wifi users Never lose signal or internet.
is my ae basestation going bad? If i dasiey chain a normal router between the modem and the basestation, there is no problem and everyone gets internet just fine.. would prefer not to have it there though.
Any ideas?

I doubt your base station is going bad - since internet access works perfectly with another router between the cable modem and your main base station. I suggest you leave it that way. There is no downside to that type of setup, and it could save you a lot of trouble trying to find out why a direct connection doesn't work reliably. There just seem to be some combinations of ISPs and cable modems that don't work well with the Airport Base Station.

New Macbook Pro + Tiger Pre installed Leopard Connectivity Problems!!!

hey guys... well let me try for the 2nd time to post this before it loses connection and crashes!!!!
on Friday i brought a new Macbook Pro 2.2ghz, for the last year i have been using a MAcbook 1.8ghz Core 2 Duo... worked flawless and loved it... but with Leopard out, i decided to take the plunge and move up to the next level and have something with better graphics and more features... so it seemed!
i erased the hdd and installed Leopard, which i had purchased for my Macbook, but decided to hold till i got this...
install went smoothly and got into OS and did the update center... started downloading... fine.... went and got a coffee... came back.... still on the first file of the update donwload.. hmmmmm weird.. normally be halfway or finished by now! i checked the wireless and noticed the send/receive was just hanging.. *not disconnected from the wireless router..* anyway i decided to hard reset the router and let it reconnect so it was fresh.. connected fine... started donwloading again.. same happened... anyway i left it donwload and do its stuff as i saw there was a key chain update which resolved some wireless issues.. great i thought.. Apple must have seen there is a problem and fixed it.. yay!!.......... heck no!
rebooted the laptop after install was done... SAME problem... not only that... i couldnt be on iChat/MSN for more than 5-10 minutes before it decided that it was going to fall asleep and stop doing anything before realizing that ****... someone is still wanting some connectivity.... by that time its disconnected/timed out from server/webpages... Webpages take about 15-30 seconds to load on intermitent basis...
Next is the bandwidth... i usually download between 180-205kb/s in Tiger on Macbook... in leopard im lucky to break the 100kb/s barrier for more than 30 seconds before it goes to 10-30kb/second!!!!!!!!! and upload speed is killed too!!!
i have read through various threads on the boards and have entered different tcp/rwin commands and turned off ipv6 in wireless but still same happens... no airport2 file either to remove..
i'm really annoyed as it seems from wanting to go to a better laptop ive only gone and brought defective hardware which i dont understand why Apple didn't test this prior to release
FIX IT quick please, i feel like taking this thing back... what use is it if i cant browse the internet which is a basic function on any laptop now a days yet vital it works!
maybe reinstalling Tiger is the only option left, there goes a weekend of installing programs/games/updates!!!!! annoyed

cheers for reply dude
will see how this gets on, also changed the channel to 6, see how that gets on..
still seems slow loading pages tho.. test from speedguide from a uk server...

seems ok?
Although RWIN TCP/IP analyzer seems to point out problems...
MTU = 1442
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1402
MSS is not optimized for broadband. Consider increasing your MTU value.
Default TCP Receive Window (RWIN) = 65330
RWIN Scaling (RFC1323) = 0 bits
Unscaled TCP Receive Window = 65330
For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:
515936 (MSS x 46 * scale factor of 8)
257968 (MSS x 46 * scale factor of 4)
128984 (MSS x 46 * scale factor of 2)
64492 (MSS x 46)
Your TCP Window limits you to: 2613 kbps (327 KBytes/s) @ 200ms
Your TCP Window limits you to: 1045 kbps (131 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 45 hops
TTL value is ok.
Timestamps (RFC1323) = ON
Note: Timestamps add 12 bytes to the TCP header of each packet, reducing the space available for useful data.

Wicd wired connection problem

Wicd works great for my wireless connections, but it falls on its face with /wired/ ethernet.
bringing up the wicd gui from the tray, I toggle off static ip / dns, and click connect.
It spins forever with the status bar message of "Wired Network: Putting interface down..."
Not really sure whats going on, and it's hard to get debug info from the gui.
Any clues?

http://bbs.archlinux.org/viewtopic.php?id=51778 --> my post might have the solution for you. Use the network daemon and delete eth0 from wired interface in your wicd preferences.
