My ethenet LAN slows down when I use a (supposedly) faster gigabit switch.

I am using the latest version Airport router. It is providing our home wireless network, which is working fine. I also have a home ethernet LAN. The Airport is connected to an old, cheap, no-name 100Mb switch. I decided to try a Netgear GS608v3 gigabit switch to see if it would allow faster ethernet LAN (of course I understand that it has no effect whatsoever on the WiFi network). The indicator light for the port where the cable from the Airport plugs into the swich glows yellow, indicating only Mb speed. The indicator lights for the other ports running cables to my wired devices all glow green, indicating a gigabit connection.
When using my web browser, I was expecting that I would not really be able to see any differences, but to my surprise the new Netgear gigabit switch was associated with dramatically SLOWER web page load times. And I mean s-l-o-w. Something is wrong here. It should be as fast or faster. And why is the input from the Airport router indicating only 100mb speed?

the problem is with the Netgear switch for SURE. you can not have packet loss on internal network.
going further:
You can troubleshoot this problem. but will take a while.
using the finder, go to network utility and select your ethernet connection,
on right side you will see Transfer statistics
if send errors or recv errors or collision are being incremented you have a problem between your mac and the switch port, (you can have problem from the switch to the router too).
In order to resolve this problem:
system preference
network
selecet ethernet
select last tab (Ethernet)
configure: manually
set speed to 100baseTX
duplex to full duplex, flow-control.
ok
apply
repeat the ping test
you can reach airport page and check for errors on lan ports.
more one tip: you need use CAT5e cables, read the cable and post the results

  • Songs slowing down when I type

    I'm running iTunes 7.7.1 on a new computer. iTunes had no problem on my old one, but on my new one, the songs slow down when I type, which is rather annoying, since I listen to music while, you know, typing. I'm on WinXP Pro, and everthing else is working great. Any ideas?

    What tools, Mostly I work with iWeb using iPhoto, Aperture, Photoshop TeXture Adobe FormsCentral for Acrobat etc. making and editing Web Sites. Often I have many Apps open simultanously.

  • Excel slows down when network drive is mapped

    Since a couple of months we are experiencing strange behaviour of excel (2011) on Lion 10.7.5
    Excel versions from 14.3.1. to 14.3.4 all the same behaviour.
    Symptom 1)
    When I connect the Time Capsule drive , Excel slows down by factor 100 when entering text. Needs up to 2 seconds to react on a key stroke.
    When I disconnect the handle, excel works fast again.
    (repeatable, reproducible)
    Symptom 2)
    on the network drive, always at the same place, a file named ~abcde.xls... occurs (exact name forgotten, but it is a recent file name
    preceded with a tilde sign)
    deleting of the file does not affect speed
    the file reappears occasionally (TC backup is switched off!)
    Where is the ghost??? :-D
    maybe these symptoms are uncorrelated.
    Why the heck does Excel slow down when I open the network drive??
    Why does this happen on 10.7.5 and not on 10.6.8?
    Anyone any idea?
    thanks,
    Stefan

    Thanks. Away on holiday right now, but will do it as soon as I get back next week.
    Out of curiosity, the external drive works fine when connected directly via USB to the laptop. I took that to mean that the problem wasn't to do with the drive, but probably the network. Is it possible there could be a problem with the drive which only shows up when it's used as a network drive?

  • Slow down when processing image clipping in photo shop with pen tool

    Adobe cs5 slow down when processing image clipping use with pen tool. The path is applying after few seconds when we draw on the image. My system supporting 4 GB memory with 64 bit.

    The main thing i use paths for in photoshop is extracting objects from photos.
    Other uses include stroking paths with the paint tools. For example, if you had
    a powerline to remove, one could trace the line with the pen tool and then stroke
    the path with spot healing brush set to content aware fill.

  • Internet speed slows down when connected via airport express

    Internet speed slows down when connecting via airport express. When connecting directly via the timecapsulethe internet speed is ok, when connecting via the airport express the speed slows down.What can I do to change that? Any suggestions?

    Turn off the AirPort Express completely as a test, and move your computer very close to the location of the Express.
    As I said before, the Express can only extend the bandwidth (speed) that it receives from the Time Capsule, so the speed that you see there with the Express powered off will be the fastest speed of which the Express is capable.
    The Express will make the signal go further when it extends....but it will not make the signal go faster.
    A good location for a device that extends wirelessly is a point that is about half the distance from the Time Capsule and the general area that needs more wireless coverage.
    If you locate the AirPort Express too far from the Time Capsule or there are more than a couple of walls in the signal path, the signal will be very slow by the time that it reaches the Express....and the Express simply extends a signal that has already slowed down significantly.
    If you already have the Express located about half the distance between the Time Capsule and general area that needs more wireless coverage, how many walls, ceilings or other obstructions are there in the signal path between the Time Capsule, the AirPort Express and the area that needs more coverage?
    Often, due to obstructions, it is just not possible to achieve good performance when you try to extend a network wirelessly. The solution is connect the AirPort Express to the Time Capsule using a wired Ethernet connection.
    There is virtually no signal loss with this type of connection, so the Express can be located exactly where it is needed and it will produce a much faster wireless signal in this type of setup.

  • HELP - 88.2 k 24-bit wav file is slowing down when imported to garageband

    i have an 88.2 k 24-bit wav file that is slowing down when imported to garageband. How do i get around this problem?

    You need to convert it to 44.1 16 bit. You can do that with iTunes.

  • Safari browser seems to slow down when working with my wifi ASUS AC 68U router

    safari browser seems to slow down when working with my wifi ASUS AC 68U router - any ideas on why?

    Is your problem with Safari on the iPad, or some MacBook Air?
    Are you sure that the ASUS firmware is tested with the device having trouble and its operating system?
    Note: MacBook Airs do not run iOS.  They run Mac OS X, Windows or Linux.

  • Can anyone answer why photoshop CS3 shuts down when I use the scanner?

    Can anyone help me with why photoshop CS3 shuts down when I use the scanner? I recently upgraded to OS X Yosemite.

    Ask in the PS forum and be much more specific. You have not provided exact system information, crash logs, scanner details. That said, this may be a compatibility issue that can't be overcome.

  • IMac from 2009, 4 GB RAM. System shuts down when I use safari or make much moves on the trackpath.

    I've got an iMac from 2009, 4 GB RAM. System shuts down when I use safari or make much moves on the trackpath. Use Mavericks, installed Mavericks again on clean system. Problem still exist. What now?

    The 2009 iMaccan take 8 GB ram, while it should run ok with 4 it might be a rather inexpensive test to put in 8 and see if that clears up the problems.  Mavericks is going to use almost 2 GB itself so, unless you are opening a lot of applications, you should get by with 4 GB.  But I would go for 8 and see how it does.

  • Since the last update of firefox, the time has been 25 to 35 seconds to enter bookmarks or even the time it takes to page down when it used to take a few seconds. can you check why it taking so long since the update on firefox.

    since the last update a few days ago of firefox, the time has been 25 to 35 seconds to enter bookmarks or even the time it takes to page down when it used to take a few seconds. can you tell me why it taking so long since the update on firefox. may another update is in order.

    I have now done pretty much every suggestion that even vaguely applies in the various helpful link provided. Thanks for the ongoing help. =)
    I have managed to get FireFox's start-up memory usage down to about 100,000K, however it appears that memory usage keeps creeping up the longer FireFox is open. (It seems to top out around 500,000K.) And I'm not talking open for many hours or days - but rather for minutes and possibly up to a couple hours. (Based on how long I've been fiddling with all this so far.)
    On the plus side, it does not appear GreaseMonkey is the culprit since with it active or disabled this memory creep still occurs. Although having GreaseMonkey enabled definitely increases the rate of memory creep. Though once it has creeped up to 150,000+K, disabling GM does not make it drop back down to the starting 100,000K.
    I should point out I run a MacBook Pro and use Bootcamp to partition the hard drive and run it as a Windows 7 PC about half the time. I am running it literally as a PC or, alternately, as a Mac depending on which hard drive I choose to load. (I'm not "windowing" it.) This problem exists regardless of whether I am using the PC or the Mac. These repairs have been made currently on the PC side, and I will attempt them all again on the Mac side. I find it odd that this enormous memory drain has occurred on 3 different computers at the same time. (The two "halves" of my home laptop as well as the PC at my work place.)

  • Does new Airport Extreme slow down when used with Airport Express?

    Maybe this is self-evident.
    If get the new Airport extreme and use an old airport express to extend it, will signal slow down to the old speed?
    Does the AE have a greater range? Perhaps I don't need the Express to extend.
    I live in NYC and there are so many signals in the air. It seems like having the additional airport helps keep me connected.
    Thanks.

    The airport express is g technology not n technology, so it will be at least as slow as your old network. Also, I'm not sure but I think the the range will be a bit longer than with the old g system, but does not have the full potential of an n system.
    I've set up my new system but none of my machines are n capable. I extended the system using my old expresses. The speed of the system is no greater than what it was before the n.
    I bought the system to upgrade my technology because everytime my Applecare runs out, I get a new computer which isn't too far down the road. I've purchased an Apple TV which will also work better with the n technology when I upgrade. It's either buy it now or buy it later. I'm also hoping that some third party like Belkin will develop a PCIX card to provide n technology to those of my computers that aren't currently n capable. I'm sure there is many like me out there.

  • Slow down when using SHARE function?

    Whenever I use the share feature to wirelessly transfer files from my Mac Air to my Macpro everything on my macpro slows down. the mouse moves slow- windows take forever to respond- or just will not close at all. I tried switching my wireless mouse to a wire and same issue. Shouldn't the transfer be a background task? Why is it effecting the overall performance of the machine?

    Your explanation makes sense; I had not considered the output size because I thought that the application would make all the necessary adjustments to the size I chose.
    I was not able to find the square pixel reference (below is the advanced area) but I did resolve the issue. At first I changed the output to be 400 x 300, and while the bars still existed, they were greatly reduced. So I took a screen capture and in Photoshop measured the height of the remaining top bar at 3 pixels. So, I reduced my height in PrE7 by a total of 6 pixels to 294 and that completely corrected the issue. Thanks for your help on this.

  • PSE 10 system slows down when adding files to catalog

    I recently switched from PSE 3 to PSE10 and had issues converting the catalog.  I never did resolve those so I decided to start with creating a new catalog in PSE 10.  My first session of adding photos worked fine.  When I restarted the task the next day, I was asked in participating in making the product better by sharing information about my use with Adobe.  I agreed to participate and very quickly noticed that my computer slowed considerably when adding photos from my hard drive.  The process still worked but I experienced a dramatic increase in the time it took for photos to be added (e.g. the cursor spins for a couple of minutes while the task is working).  I went under my account preferences and opted out of the product participation program but the problem has persisted.  I rebooted the computer to see if that would help but it has not.  I have turned off all media analysis and both optimized and repaired my catalog and while this has provided some improvement, there are still instances where the system slows down.  Now it seems that every other folder's worth of pictures (does not matter how many photos) I add causes this delay.
    I appreciate any help anyone can provide in determining why this slow down keeps occuring. 
    FYI, I am running a new Windows 7, 64-bit system with 8GB DDR-3-1066MHz, and 2 TB hard drive.

    Have you also edited the Preferences (Performance) to increase the amount of RAM that PSE can use?
    Do you have many background processes running?  Having a single HDD means that everything running on your computer has to wait in the queue for disk access.
    How many photos are you importing?
    What file types are the photos?
    How large are the photos?

  • Itunes slows down when sharing music is enabled

    hi,
    i searched through the forums and i didn't see that exact issue so i decided to post it.
    as soon as i share my library itunes completely slows down.
    - starting to play songs takes 5 seconds and displays the rotating rainbow circle
    - rating songs takes 5 seconds also and displays the rotating rainbow circle
    - resuming play after pausing also
    there are two more interesting issues:
    - i have a few albums where it doesn't happen! the albums aren't encoded different, have the same version of tags, are on the same drive in an adjacent folder. i tried reimporting songs, placing it into different folders or harddrives. no changes.
    - only 2% of my library is shared and it seems like most of it is recently added music. but: no differences in encoding, tags, place on the harddrive. renaming, readding, moving the files didn't change the situation.
    i also disabled automatic updating of playlists, deleted all my playlist folders, reinstalled itunes, tried basically everything.
    what does itunes do in the network when playing, rating songs, ...? i'm using a fast wlan, but i don't think that's the issue or does itunes reexport the xml-file after every play? has it something to do with auto-update-play-counts after every song (which i couldn' find in the preferences)?
    any help would be greatly appreciated!
    regards,
    eric.
    by the way: i'd loooooove to see pandora-like functionality in the next major versin of itunes!!! :)))

    When you are sharing your iTunes, any other users you share with are accessing your hard drive and music foilder simultaneously with you. Since shared users are not playing exactly the same song at the same time as you, your hard drive's heads are scanning and reading from more points than they would be with you alone listening. There is a need to cache some part of the files for sharing, and that uses a bit of your RAM too. I guess it would be similar to saying that your car drives fine as long as you are driving it alone. Pile a few friends in with you, tow their cars behind yours, and suddenly, your car has nowhere near the performance it did with just you in it. Aside from adding more RAM, buying a fatser hard drive or stepping up your processor, this is simply an issue with sharing one system between more than one user at the same time, and it can't be remedied.
