Slow Firewire Networking

Hello all.
I am having a very odd issue with my new Macbook Pro. When it comes to moving data between my iMac desktop and my notebook I have always connected the machines by firewire cable and connected via networking (much faster than using an airport network). For some strange reason with this Macbook Pro if I am transferring a large file, it transfers at full speed for the first 100mb or so then it slows to a crawl. If I connect via firewire cable in 'target disk' mode, it all works fine and the transfer runs at full speed. I never had this problem with my old Macbook. Anyone have any ideas?

I've been noticing this myself the last two weeks... FW Sharing really hogs the CPU down. I quit using it as other FW devices hooked to either weren't seen, (HDs actually).
I don't think it's the FW per se, but the IP part of it. Mine shows an MTU of 2030, which I'm now wondering if it can be adjusted, because even Gigabit Ethernet without the Jumbo Frames, (MTU=9000), suffers a lot of speed reduction, and increased CPU usage.
Same Computers with one in FWTDM doesn't show the high CPU usage.
On your devices that aren't seen, what are they?

I have a 1st generation time capsule and an extreme b/g. Is the extreme slowing the network down

I have a 1st generation time capsule and an appe extreme b/g. Is the extreme slowing the network down? Should I dump it an get the new n version?

yes it is likely to be slowing down the network because you are using 802.11b/g
from what i recall with b/g a slow client can slow down the entire network to that clients speed.
this was the major improvement with 802.11n and Mimo. each client can be connected to the access point without affecting your speed to the rest of the network
its reccomended to get all new "N" equipment if you have the budget for it. some of those old airports and time capsules can still be worth something on amazon marketplace so you might be able to sell them
if you want to create / join / extend a netwowrk your going to probably need all "n" based equipment.
buy the new 4th generation time capsule or the new 5th generation airport they have better stronger radios
in the mean time configure your base station router to a high multicast rate, so it will prevent devices connecting to it at 1-2 mbps speeds and slowing down your network
if you have an apple care covered mac remember the airport / time capsule rule. all airports and time capsules purchased 2 years before you bought your mac to the 3 years of apple care covers them. if you do not have apple care then the standard warranty applies

Firewire-HDD plugged to MacPro unmeant mounted on iMac via FireWire network

Hi folks,
I am from Germany with the following problem.
I connected two MACs - Mac Pro (10.5) and iMac (10.6) - via Firewire for networking.
Now I bought a FireWire 800 HDD and plugged it into the MacPro for faster access to video-data. Unfortunately every time I turn on the HDD it is mounted on the iMAC???? I always have to pull out the FireWire network-cable from the iMac before. Than it works and the HDD is seen by the MacPro. After that I can plug in the Firewire Network-cable back into the iMac for work.
Is there a solution? Is it possible that it matters which port I use for network or HDD...??
Thanks for help, Andy

Hmmmmmm, it is really simple....:-)
1.) I have an iMAC with connection to Internet.
2.) I have an MacPro which has no connection to Internet and thats what I want.
3.) Sometimes I need to share Files between iMac and MacPro, so I have connected them permanent to a Mini-Network via FireWire.
4.) I work with FinalCut on the MacPro
5.) I bought a FireWire HDD for use ONLY with MacPro NOT to share it.
6.) I connected the FW-HDD to the MacPro
7.) I turn on the FW-HDD and it appears and is mounted ONLY by the iMAC what I DO NOT want.
8.) I turn off the FW-HDD
9.) I disconnct the two Macs from FW-Connection
10.) I turn on the FW-HDD and it appears and is mounted on the MacPro what I WANT
11.) I connect the FW-Network back on, to share Files between the MACs - NOT from the FW-HDD, (it is ONLY for the MacPro Video) but from the internal drives.
12.) So far, so good.
13.) Problem: I want to mount the FW-Hdd to the MacPro by turning it on without disconnecting the two Macs.
Better????

Firewire networking not working

At work, I have been using firewire to connect my MacBookPro to a G5 10.5.8 (that is the highest OS X that supports its PowerPC’s). TheG5 has a number of large disks including one that is used for timemachine onthe MacBook Pro. It worked welluntil yesterday when I installed Lion. Now the MacBook does not see any disk onthe G5, nor does it connect to the internet when “internet sharing” is turned “on”,on the G5. When started in Target mode and connected using the Firewire, thedisks are visible.
I can still access the G5’s disks by connecting to the slowand unreliable wireless network, so timemachine is not completely cut off.However, this needs to be fixed for the long term.
Thoughts?
BTW: using the new Safari to create this little message was a disaster. Finger slips deleted the page a number of times (not even sure what gesture I did) so I ended up writing this in good ‘ol Word andpasting it in. Apparently the “recoveranything” feature of Lion does not apply to text boxes in Safari.

When we connect the isight camera in ANY of the ports of the Server and the firewire network cable is connected, the status of the ichat camera turns off or used by another device, but the network status is green if we disconnect the network cable.
Interesting to read this as I have this exact same problem on an imac G5 with firewire cable to external drive in one port and ichat camera in the other. Cannot normally get both to work at same time. The external drive is being used as a Time Machine backup.
The apple article on How to Troubleshoot iSight quotes
If more than one FireWire device is connected to your computer, there may be an incompatibility between two of the devices. To rule this out, disconnect all other FireWire devices from the computer, including external hard drives, CD/DVD drives, other cameras, and FireWire-based networking equipment, such as hubs and repeaters. If your iSight camera works normally when you remove other FireWire devices, plug them back in one at a time to isolate the cause of the issue.

Turn Off Firewire Networking. You need to do this!

10.4.3 install turns on firewire networking. If you are using a firewire interface, turning this off greatly improves performance. Go to system preferences, network. In the show menu select Network Port Configurations, and turn off "built-in firewire".
This has vastly improved stability with my mlan firewire stuff.
When switched on, osx constantly monitors the firewire ports for a network.

What is "fast user switching" (and where is it found)?
Also, will turning off FW networking affect whether or not Target Disk Mode will function?

Firewire network V's ethernet 100

Would FW400 network be faster than an ethernet100 I understand the distance limitation but I'm looking at it for a few mac miniG4's in an xgrid setup. We xgrid run over Fw400 is the next obivios question?

You're supposed to just need a FireWire repeater (it's like a hub). In my expereince you just need to daisychain the computers. If the TOTAL distance is more than 15 feet, you need to put a repeater every 15 feet. Max distance for IP over FireWire is 237ft.
I quite often share my external SuperDrive between my iBook and mini and have FireWire networking on at the same time.

Firewire Network Sharing

I want to make a private firewire network to share a folder for quick access between two iMac, they are also on the same ethernet network, how do I share a folder between the two computers only for the firewire connection?

If your two Macs are already networked, why do you want to double-up with FW networking also? If both network connections are active, you can't control the routing of specific traffic over one vs. the other. Traffic will generally move via whatever network connection is at the top of the list in your System Prefs > Networking panel even if more than one network is active.
In System Prefs > Networking > File Sharing you can set access permissions by folder and by user. That should accomplish the security you seem to be interested in. Or are you specifically interested in preventing certain transfers from being physically carried over the ethernet network?

Firewire network

Hello !
I want to connect 2 imac G5 to one external firewire hard drive (maxtor 20 Go)
I found at unibrain.com the software called "Firenet" which is supposed able to create a network through firewire ports
is anyone try it ?
I want to connect the 2 imac with a firewire cable and with the external HD connected to imac n°1.
with ethernet connection : when I want to make transferts from the imac n°2, imac n°1 speed down. is this fall of speed is solved by using the firewire ports ?
p.s. excuse for my perharps approximative english !
thanks
2x imac G5 - 1,8 Mhz - 1,25 Go - HD 80 GB Mac OS X (10.3.9)

thanks for you help
the 2 macs are connected through ethernet network
see below
actual connections
HD<-firewire cable->mac n°1 <-ethernet network->mac n°2
expected connections
HD<-firewire cable->mac n°1 <-ethernet network->mac n°2
!______firewire___________¡
when I make huge transferts via ethernet network, mac n°1 slow down dramatically
is the 2nd configuration can improved transferts ?

I am desperate!! slow choppy network speeds (not actual inability to cnnct)

I have a 13" macbook air that has the following problem: I can connect to wifi networks (including at home WPA and also tried WPA2 settings) but even though I may get proper speed at first, I soon lose that and it becomes much slower and choppy (if I open activity monitor I can see the speed going up and down like crazy...). My internet speed at home is 12mpbs set by my provider. When I perform speed tests (vis speedtest.net or downloading files from other speed test sites) on my windows PC that is also on this network I get the full download speed. However with this MAC while I initially did get the full speed, it is now down to an average of 3-5mbps and the activity monitor, again, shows choppy behavior so it will be at 8 then at zero almost and then up and down again but never near the full speed. I tried to connect to other networks and I have the same problem - once this happens it stays. I tried removing the airport connection in network preferences and adding it again it does not help.
I TALKED TO APPLE AND HAD MY COMPUTER TESTED BY THEM - they didn't find any hardware issues (they said it was fine - but it isn't) but they still replaced the airport hardware in the computer - both the chip and the antenna (which meant replacing the entire screen). I brought the computer home, ran a speed test and everything was fine. I thought GREAT but then something happened and the problem returned. What I did (which I think was unrelated) was connect via SMB to a PC at home and I tried to stream a movie file. I noticed it kept 'pausing' so I opened up activity monitor again and to my HORROR I saw the choppy wave with network speed very inconsistent going up and down like crazy... I tried connecting to my slingox using the sling web access after disconnecting from my home PC but got partial speed and lots of drops too. I tried the speed test again multiple times, nothing seems to work.
SO I don't know what to do at this point. I have 10.6.6 running. I heard something about a firmware update but I am new to mac so not sure how to even do that or what else I can do to solve this problem or what is causing it. BTW - logging in now from the guest account still does not fix the issues and they remain the same.
I am desperately looking for help!!
Thanks a lot!

Have you been able to reproduce your problems on other wireless networks other than at your house? It appears you are saying that this occurs on all wireless, but I'm not sure from your comment. If it's only at home, it would appear to be a compatibility issue between your wireless access point and the Macbook Air, which isn't uncommon. Sometimes a firmware upgrade to the access point can fix it, sometimes it might require switching to a different brand of access point. It would be great if you could borrow (or buy and return) a different access point/router to test. An Apple airport would be the best to use of course. Not the easiest solution, but lets you help rule out a hardware issue with your air.
My isp provides 15mbps but my wireless devices such as my iphone, ipad, laptop usually only get 6.5-8 mbps when testing speeds to the internet. I don't expect it to be as good as the wired due to interference, signal, etc. I don't get the choppy behavior however. Firware updates from Apple will appear in the same manner as standard software updates. If there is one available for your system it should appear when you check for software updates. That being said, I believe you can also manually download them from the Apple site.

Color HP LJ CP3525N printing slow on network for one but not another

This one hasn't been touched upon that I have notced. I currently have a Color LaserJet CP3525N setup on Server 2003 R2 with PCl6 drivers being used. This just started occuring for people on the same subnet as this printer. The print jobs go very slow and print a single page about ever 3 minutes. If I print to the printer with the same drives setup from the same server it prints with no delay. My system is a Windows 7 64 bit and the other systems are also Windows 7 64 bit as well. Before this week it was printing for many months with no problem. This printer is used quite often and I am now being stopped from my daily work and having to have the files emailed to me to print. I have searched other forums and threads and notbody else seems to have this issue. I have stopped and started the printer spool on the Server and that didn't make any difference. The server it is on is the main one we use to share out all of our network printers. Any thoughts or ideas? I have also replaced the 4 toners to see if that resolved anything as suggested by others and still not dice at this point.
Thanks in advance,
Marcus

Did a fresh install and still having the same problem. Giving up now. Mod can now close this thread

Windows 7 running slow on network.

Are there issues with the network interface card using windows 7 installed with Boot Camp?

I experience this too - it *****!
I saw another thread where the only suggested solution was to install VMWare instead of using BootCamp .
https://discussions.apple.com/message/19469272#19469272
If knew that a MacBookPro could not run Windows 7 properly using BootCamp, I would have never bought, since I use Windows7 for work and the Mac at home. I just can't live with slow network access at work

Lion 10.7.4 slow accessing network folders

I'm using a networked hard drive to access files. After going to a system with Lion it is very slow accessing some of the folders. Sometimes it can take up to a minute to open a folder with vew few items. After updating to 10.7.4 I'm noticing some folders will not open at all and I have to restart.
Any idea what I can do to fix this??
Thanks!

10.7.4 ???!!!??? Oh, sh***!! Hide the women & children! The Mayan witch doctors were right, the world is ending.....

So slow listing network shared folders and drives.

Hi!!
I'm reporting a very slow connection between my MacBook Pro 13" (snow leopard) and my MacPro 8 core (leopard). When I try to reach the macpro in finder (shared) passed 1 or 2 minutes until the system ask me user/pass, then show me the list of my shared folders and drives. Navigating through them is ok, ut when I return to the main list, SnowLeopard again waits 1 minutes or 2 to show. Before, the main list always remain there.
Any help??

Same sort of problem here. Screen Sharing also doesn't work.
Pretty sure it's DNS, as if I temporarily remove my router from the equation (by, say, using a manual IP address instead of DHCP on the machines and leaving DNS blank) everything works and is instant - except of course for the internet. Put it back to DHCP (which uses the router for DNS) and it's slow again (and screen sharing doesn't work at all).
However, OpenDNS hasn't helped (probably because it's a private address range?)
The network is 192.168.0.0/24 with gateway and DNS server 192.168.0.1, which is a Draytek Vigor 2600G ADSL router.
This has only happened recently, I guess Snow Leopard or one of its updates has forced reverse DNS lookups for everything.
As I understand it, AFP is supposed to use Bonjour for hostnames ending in .local and bypass DNS altogether, but despite checking that they end in .local (an automatic thing) in System Preferences it doesn't seem to do this any more.
Any way to turn off these reverse DNS lookups?

Firewire network fails when I turn Airport on

1. I want to network two tiger machines via firewire, for backup purposes.
After I've connected via firewire (manually via "Go" menu, since nothing else works), I turn my Airport back on, and it dismounts the connected volume. Why is this happening, and how do I stop it?
2. The reason I turn airport off is because bonjour seems to default to it, even though I've put firewire at the top of the list on both computers. Is there another way to face this problem?

This problem has been solved. John at Apple Support spent quite a bit of time with me on the phone until he fixed the problem. Turns out that my router had assigned the same IP address to two of my devices. He had me go to Preferences>Network and delete Airport, then restart and add Airport. That time it selected a different IP address and all was working again. Thanks John.

Slow firewire transfer speed in Snow Leopard

Hello,
Everything works fine in Snow Leopard, besides copying large files to my external Freecom firewire hard drives. Having a dual boot system with also Leopard installed, the problem only exists in Snow Leopard. NVRAM/PRAM reset doesn't help.
Does anyone have a clue ?
Thanks in advance,
Beliarus

I have a FireWire 400 HD, it has a JMicron chipset (pretty generic but works great). I worked wonderfully on Leopard without a single glitch ever.
Now, after upgrading to SL, I experience the same as you and the drive is not responding well, hanging constantly and experiencing really slow transfer rates, that make it unusable (all applications that try to open something from it eventually hang). It's not a temporary glitch, even after several reboots and connecting/disconnecting the drive. The same drive under USB2 (it also has USB2 interface) works perfect (but I really want my firewire back).
I hope Apple fixes it! Definitely a bug.
