Slow Ethernet Connection on Mac OSX 10.5.3

Hi,
I own a Macbook Pro with 10.5.3 and I am having a lot of problems with really slow connection. This is only happening in OSX though. I booted into Windows to see if it was my card and thank god it isn't (I never got Applecare).
Is anyone else having the same problem?
(posted this in the Macbook Pro forums as well)

Hi ThePanda-
Have you tried connecting via a wired connection?
That would help narrow things down.
Luck-

Very slow ethernet connection

Hi there,
I have a question about Gbps ethernet speeds. I'm a total networking newbie, so forgive me if this all sounds a bit ambitious or ignorant.
I'm in the process of upgrading from my maxed out Mac Mini to a MacBook Pro and I bought a Lacie 500GB Ethernet mini disk in order to store large video files and, ultimately, to use the Lacie drive as a wireless drive over Airport Extreme once I get myself organised and also upgrade to the new Airport Extreme -basically, I don't want to clutter up the MacBook Pro's hard drive space
Anyway, for the interim I have connected the Mac Mini and Lacie drive directly via Ethernet cable to start transferring the bigger files across from my old 160GB Firewire drive and other large files on the Mac Mini
Now, both the Mac Mini and the Lacie claim gigabit ethernet speeds, but the reality is that transfer speeds between the two are incredibly slow. For example, it took 6 hours to back up my 62 GB Home Folder via Backup - not quite the 1000Mbps I was expecting. In fact, I suspect that the USB 2.0 option with the Lacie at 480Mbps would be a lot faster.
Setting up the Lacie drive was easy and I'm transferring some pretty hefty files across; however, everything is just so slooooow. Am I missing something here? Have I completely misinterpreted ethernet capabilities or could it be that the Mac Mini is slowing everything down?
Being new to networks networking, I simplly don't know where to start making the tweaks.
Thanks in advance.

1 network speeds are measured in bits per second, data is measured in bytes.
2 typical real-world throughput for a 10 Mb/s connection is 5-7 Mb/s; for a 100 Mb/s connection, 60-75 Mb/s; for a 1000 Mb/s connection, under 800 Mb/s. (Copper cable, of course. Fibre is faster, but much more expensive.)

Warning: wireless speeds have even less in common with advertised maxima than do wired speeds. 802.11g theoretically tops out at 54 Mb/s, or a bit more than half the speed of a 100 Mb/s cable. Unless you're right next to the router you'll be lucky to get more than 30 Mb/s. 802.11n similarly promises 108 Mb/s, and delivers under 80 Mb/s. Often well under 80 Mb/s.

Six hours is 6 x 3600 or 21600 seconds. 62 GB is 62 x 8 or 496 Gb. That's 23 Mb/s, or 2% of theoretical maximum for a 1000 Mb/s cable, or about 20% of the maximum for 100 Mb/s cable and for 802.11n or about 40% of the maximum for 802.11g, and you're more than double the top speed for 10 Mb/s cable. If you're using 1000 Mb/s cable, you've got a network tuning problem. You should be able to get that info over in under a hour. If you have good equipment, in under 20 minutes. If you're using 100 Mb/s cable, you're slow but not too slow. If you're using wireless, you're in the ballpark.
Note that 1000 cable will be twice as fast as USB 2, but 100 Mb/s cable or 802.11n will be twice as slow.
Setting up the Lacie drive was easy and I'm transferring some pretty hefty files across; however, everything is just so slooooow. Am I missing something here? Have I completely misinterpreted ethernet capabilities or could it be that the Mac Mini is slowing everything down?
The mini will never be a speed demon. Part of your problem is that high-speed transfers are not its thing. However, it should be way faster than what you report.
Being new to networks networking, I simplly don't know where to start making the tweaks.
What else is on the network? What else is running on the various Macs? What kind of physical cable do you have, cat 3, cat 5, cat 5e, cat 6, cat 6e? Is part of the net on wireless?
Thanks in advance.

Slow download connection on mac only

Hi there!
Most of the times when I download a file the speed is not even 30kb/s, whereas on my old pc (win xp) it's up to 1-2Mb/s. The speed test on mac shows a reasonable download speed though.. I tried different browsers and to connect my mac to both ethernet and wifi. I cleared the chache and reset my router, but nothing seems to work. I bought my mac just 3 days ago, so I really don't know where the problem could be.

Hello, good clue with Safe Mode, more info on that...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

E-mail connection problems Mac OSX V. 10.6.8

I'm having problems connecting to my e-mail. When I do I get a message informing me that I have Mail version 4.5, and it can't be used on my current version-Mac OSX Version 10.6.8. Can anyone give me some advice on how to fix this problem? I'm relatively computer illiterate. Thanks.

Hmm, it might explain why you are posting a question related to 10.6.x in a forum deicated to 10.8.x...
Click onto the apple icon in the uper left corner of the desktop, then choose Software Update. Since Mail is part of OS X, perhaps some update will help.
Else you might need to re-install OS X. But first, make sure you have a backup.

"No network connection" on Mac OSX Freedome client when entering the code

Hi, Freedome Mac OSX lost the subscription information on version upgrade from the Beta version to the full version on last night. When I tryi to re-register using my existing code the application just shows "No network connection"-dialog and exits. What to try next? The Beta version client did not have any issues and now I'm not able to use my subscription. Regs,Harri

Hello Harri99,
In order to make sure all traces of the Beta version are gone, please proceed to uninstall as follows:
-Remove Freedome from /Applications.
- Delete the folders "/Library/Application Support/F-Secure/FSFreedome" and "~/Library/Application Support/F-Secure/FSFreedome"
-Remove "Your F-Secure Freedome Key" from your login keychain (it's in Passwords category).
-Reinstall the latest version available here.

TC slow ethernet speed w/ mac mini, not anti-virus

new TC 1tb, running wireless to one macbook pro, one sony laptop, and ethernet to mac mini. update done to TC, including airport utility. no anti virus.
using it as the primary wireless source, with cable modem.
first backup was awfully slow, both by wireless, then do-over by ethernet.
speed on local network streaming mp4s through ethernet cable is bad to awful. copying files from TC to usb (in mac mini) is awful. searching for songs through itunes is slow (though library is 500gb).
the heat explanation is of course, just laughable. you give me a beautiful flat piece of equipment and you don't expect me to put my mac mini on top? terrible design flaw if true.
also, tried the re-boot and the shortened DCHP time.
no other good explanations that i could find.
So unless there are some great ideas out there, i guess
i should understand from all the threads that this thing just doesn't work as a primary file server. and its not so good at backup either.
its just too slow. please help if anyone has another suggestion, but i think that regardless i have to take it back.
glad i didn't erase my library from the WD My Book.
what a waste of my time this has been.

just bought a new 12" Powerbook and it will not connect to my local dial up ISP any faster than 28k. I've had the same ISP for over ten years. I've had the same phone line in my same apartment for over ten years. The G3 iBook I just sold connected at 56k almost every time. The G4 iMac I have at home connects at 56k almost every time. The Performa 6400 I used to have connected at 56k almost every time. The G4 Sawtooth I have in my music studio a couple of blocks away using a different phone line connects at 56k almost every time. Same ISP for over ten years, two different phone lines that work fine with four other Macs, the only Mac I've had that won't connect at 56k is my brand new Powerbook. It won't connect at 56k using OS 10.3.9 or 10.4 or 10.4.4. I tested the connection with CNET's online modem bandwidth test page and the Powerbook modem was connecting at about 26k.
so I took my PowerBook to the Apple store in San Francisco, they sent it to be repaired and when it came back said they replaced the modem, but it still won't connect at 56k when all my other Macs will.
so I took my PowerBook back to the Apple store in San Francisco, and they connected it to a phone line and got a 31k connection and told me, Well the modem connects, so as far as we're concerned it works, and 56k is only the maximum theoretical connection speed and Apple does not guarantee you will actually get that modem baud rate, so we are not going to do anything else about it. I told them that there is nothing theoretical about all my other Macs connecting to the same ISP at higher speeds than the PowerBook and that Apple should be able to test the PowerBook to determine if their own tech guys can get a 56k connection with my PowerBook. The Apple store "genius" called his manager, who refused to do any more work on the computer.

Very slow network connection on Mac Pro

I have a FiOS connection and good speeds on my Macbook Pro and iPad. However, my 2010 Mac Pro connects like a dog. I just connected to my yahoo page which gives typical results. On my Macbook Pro it took 3-4 seconds. On my Mac Pro it took 58 seconds for the initial page content to arrive on my screen and 1:40 for the page to be fully loaded. This is typical. It doesn't matter if I connect through ethernet or wireless - same results. It doesn't matter which browser I use.
I ran speedtest and the results were actually better on the Mac Pro - I have no ide why
Mac Pro ping 16 ms DL 30.73 mbps UL 14.28 mbps
Macbook Pro 17 ms DL 20.58 mbps UL 14.22 mbps
2010 Mac Pro, 3.33. ghz 6 core with 32 gb of ram running 10.8.2
Any suggestions.

Please read this whole message before doing anything. This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it. Step 1 The purpose of this step is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. For instructions, launch the System Preferences application, select Help from the menu bar, and enter “Set up guest users” (without the quotes) in the search box. Don't use the Safari-only “Guest User” login created by “Find My Mac.” While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin. Test while logged in as Guest. Same problem? After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it. *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing. Step 2 The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

Slow ethernet connection after WOL in win 7

I installed windows 7 on my mac mini and installed all drivers. after 2 days I decided to enable WOL but I faced a very slow file transfer over my network.
I disabled WOL but currently I face random slow connection on file transfer, slow as as 50 Kb file transfer.
thanks for your help

I had the same issue but it was with Wireless. Goto your DNS settings in Networking in system preferences and click the minus button after clicking the DNS that shows up. What that will do is auto-reallocate the DNS for your router. It may be that issue, that is why mine was so slow.

Slow to connect to Mac share - file and screen

I have a few Macs on a network, with wired and wireless connections. I'm finding that I can connect to some of the machines quite quickly - from time that I click on the machine in the Shared area of the sidebar to when I see disks appear, or from when I click on screen sharing to something appearing, is fast. This is true for a PowerPC Mini running 10.5.x - takes 1 second for disks to appear.
At the same time, I have a MacBook Pro, 2.8 GHz, running 10.6.6, where it takes as much as 15 seconds for disks to appear or screen sharing to start. This happens with wired or wireless connections to the machine - I can be wired through a gigabit switch between that machine and another fast machine and still takes 10-15 seconds. This has been occurring for some time, and was present before and after the 10.6.6 patch.
Once I am copying data between machines, things seem to run quickly. So it seems mostly to be at the initial connection. If I go to sleep on a machine that is already connected to this MBP, wake up, then click on the MBP again, even though have mounted shares it still took 15 seconds to re-display the shares.
Any idea how I might diagnose and fix this?
Thanks,
Alex

There is no external drive on this machine - and I verified that the disk is awake. Not the issue.
The wired test was done between Macs on the same gigabit ether switch.
Another clue - I've found that when playing Starcraft 2 on this machine, this machine is the last to load vs others in multiplayer. I'm playing side by side with another machine on an older MacBook Pro, slightly slower, and that one always loads faster.

Nokia Lumia 920 - Not connecting on MAC OSX 10.6.8

Hello everybody,
I have this problem that alot of people are encounting but it seems having no solutions yet.
I bought my Nokia Lumia 920 a couple days ago, made all the updates alvaible but still I can't connect my phone to my MacBook Pro.
The funny part is that my dropbox application on my mac detect my phone and tries to import my pictures where neither iTunes or Finder are able to recognize my Nokia.
The all support we got is to download a app which is not working for the OSX 10.6.8 and they seem to force us to upgrade to the 10.7 OSX.
It is my right, as a consummer, to choose to OS I want for my laptop and it is to both Windows and Nokia to make their devices compatible to their customers computers.
So here is my call to all Nokia and Windows developpers: Do not ignore us, there is a problem and the first step in order to solve it is to recognize this problem.
The least you can do is to tell us that you are currently working on it because I feel all alone in the dark but I am pretty sure I am not alone and you might loose some clients that are delighted with your phone but really "**bleep**" off the way that they are treated in the process of solving this important problem.
Thank you for your time and comprehension,
I am looking forward some advices from any developpers.

I have to raise a different view point. Many users of macs are ordinary, non-techie people, who simply want a machine to do basic things. I know people with very old macs, and they are happily using them for simple purposes. I have 10.6.8, and any upgrade would cost me some money to upgrade parallels. Macs can run for years, and I believe that it is important for equipment to be able to be used for long periods of time, if the user wishes. Also, earlier OS are very commonly unsed in coutries where money and internet is not as available as to many of us.
I also use a mac with XP as I need a small install base for only one PC based software that I occasionally use.
As a developer, I would expect them to look at the actual installed back of OS, and realise that some simple functionality should be backward to existing users. The ability for a phone to connect to earlier OS is something which I did not even think about - I thought it would be automatic. Its also not that difficult to develop.
The forums are awash with frustrated new pruchasers of Lumia phones, suddenly realising that their expected functionality with PC Suite, etc has now gone. Many of those people are very frustrated, and they will pass on their frustrations to others, and sales will be affected.
I have been a Nokia user now for about six years, and I have watched the same frustrations of users, requesting Nolia to develop expected connection, integration, and sync software that other phone manufacturers seem to be able to do. Finally, a reasonable PC Suite version is now developed, but not compatible with Lumia?? Do we have to go through the whole waiting thing again? Why cannot Nokia look at this not as a software problem, but an expected functionality feature.

Connecting to shared internet connection through Mac osx 10.7 wifi

I can't get my new HP touch pad to connect to my wireless network. I connect my iMac through ethernet but have a wifi network setup from my iMac so my other devices can use my iMacs shared internet connection. The touchpad will not connect, it finds the network, I put in the WEP key and it states "unable to connect, try again". I am at the setup stage on the touch pad and can't get any further!!. I have tried everything I can think of including creating a new wireless network, disabling and changing the sharing password and re-enabling. all my other devices still log on fine and can connect to the internet through the iMacs connection. anyone got any ideas?

I just remembered why I ignored your first post when reading this topic:
Ad-hoc-sharing can't be the problem, because when I use the exact same method without any WEP encryption, so create an open network, it works perfectly - so it has to be an error in the webOS' handling of WEP or similar...
I'm curious that the Mac offers only ASCII (key length of 5 characters) or 128 bit encryption, but not 64bit (which has a key length of 10 hexadecimal characters and works perfectly with my touchpad). <Wiki definition of WEP.>
This sounds like an old problem we used to have when Palm came out with WiFi-enabled devices. Users would create an ASCII text password in their router, and it would generate a 10 character hexadecimal string that was the true password. Entering the 5-digit ASCII code would fail since it was a seed, and not the "real" code.. Entering the 10-digit key worked every time.
By any chance is this what is occurring on the Mac? Do you see a 10 digit code generated anywhere in the setup routine?

Airport Express-slow ethernet connection 2

Sorry to nag, but I have posted this AE speed problem before with no responses. Have an AE set up as a wireless access point on an ethernet network. [Router:8 port switch] to a distribution switch to AE. WAP2 128k. Know the connection is valid, RF 2-4 bars and can do email and iTunes at <100 kbps. Pinged my own router and have a 30% packet loss. Same-o same-o to outside servers. When I try to load a Google search page, it takes forever if at all. Hard wired path to the same port works fine, speed is up and no packet loss. So my question remains: waz up?

Have you tried changing the channel on the Express?
Many times the signal strength will look good but
there's enough interference to slow down the
throughput.
I tried changing to channels 3 and 10 as well as setting the multicast setting to 5.5, still no luck. Thanx for the advice, I'll keep working on it. cedar

Photosmart all in one B210a showing offline - no connection to MAC OSX 10.8.5 nor IPad

NEVERMIND! It's working now! (Of course as soon as I give up after 4 hours and contact the Forum, NOW it works!!)
Thanks anyway!
Changed my router from the factory default name and password settings. Reconfigured printer to recognize router, and the display & printed page said there was no problem / set up successful. Then I downloaded the most recent update to my printer from HP website. The only "device" found was HP Photosmart "[F7E632] Bonjour multifunction." (I never saw anything prior to this with the F-coding nor "bonjour" information.) Now when I try to print from the Mac, the print que message says the printer "may not exist or is unavailable at this time." When I try to print from the IPad, it says the printer "is offline."
I'm not that computer savvy, and I am COMPLETELY at a loss as to how to troubleshoot this. Can someone help me?
Thank you.

Hi @Riversend ,
I understand you were able to resolve the issue you were experiencing. I am sorry to hear that it had been so time consuming. If you ever need support in the feature of course you can come back to the HP Forums, but you can always use your printer support page as well.

ESATA: connecting 2 mac pro's via esata to each other

has anyone tried to connect 2 mac pro's via esata directly to each other (instead of the slower ethernet connection)? i was hoping to install esata cards into the pci-express slots into 2 mac pros and instead of the usual ethernet connection between the 2 so they can file share, i was hoping for a faster estata connection if that is possible. would i see the computers in the usual finder window under "shared?" note: the mac pro's would be physically close to each other, so cable length connection is a non issue.

Hopefully no one would try this.
NAS or FiberChannel like Apple did with XRAID.
OS X client is not designed to handle file-locking and device sharing, not in this manner.
Linux or HP type media servers
