Why is my ibook so slow on the network?

It seems that when I use Wifi with certain public networks some of them are much slower than others. But the speed issues are only felt on my ibook but not on the PC. For example there is one public library around my area that I can access with my ibook. It seems to take FOREVER to access FTP (either with OSX Fetch or Transmit 1.7 (which runs in Classic). It also seems that websites are rather slow. But the problem and why the IT people will not listen to me, is that I am usually the only person in the entire library that is using a Mac. Everyone else is using Windows and even I have used Windows and these problems are non existant on the PC. Why is this?
Any of my FTP servers that I try to access on my ibook takes days to load, and most wbsites are very slow. But this is only a problem on the ibook and not on the PC's.
You may think I have a configuration problem but think again after you hear that when I get in my car and drive some 15-20 minutes away to another library and access their Wifi network my ibook works just fine!
This is very strange.
Thanks for any tips.
John

The library probably just has their network misconfigured. They got it working on Windows and don't care about the Mac. It is definitely the library's problem, not your Macs. You won't be able to fix it.
This is uncommon, but not unheard of. I had an interview at Microsoft once. I couldn't get my iBook to work with the Wifi (or hard-wired!) network at the hotel across the street. I even called up tech support. They had the netmask completely wrong. It only works on Windows because Windows doesn't conform to networking standards. For some reason, the hotel that Microsoft puts all the interviewees in doesn't work with Macs. Go figure. I didn't get the job. Maybe because I took a Mac to an interview at Microsoft. Hey, I have my priorities!

Why are my MacBooks so slow on the network when everything else is fast?

Last month, my apartment complex changed its network from a pretty wide open Wi-Fi to one where we must enter a user name and password every 30 days for each machine. Since then, both my MacBooks (2012 MBP running 10.8.3 and 2008 white MB running 10.7.5) have very slow connections. Web pages will fail to load, or load incredibly slowly (as in the progress bar moves an inch then stops). We get bursts of activity (as also seen in Activity Monitor) lasting for seconds (limited to 4mbps down/0.2mbps up by the new ISP). This occurs on both Safari and Firefox. iTunes music store, the Mac App store, Mail, and Spotify all exhibit identical behavior. My iPad, iPhone, and another's Windows netbook connect without any obvious difficulty. We had a rep from the new ISP come to check out our connection, and he believes that the problem is directly related to the MacBooks (a virus on both?).
Things I've tried without change in behavior (with the 2012 MBP):
1. Connecting directly to ethernet (and turning off AirPort).
2. Restarting the computer and the router.
3. Logging in elsewhere in the complex
4. Changing DNS to 8.8.8.8 and 8.8.4.4
5. Deleting AirPort and re-installing in System Prefs
6. Following the excellent "Step by Step to Fix Your Mac" https://discussions.apple.com/docs/DOC-3353 on these forums, including clearing every cache imaginable with Onyx, and uninstalling Java, Silverlight, Flash, and any System Pref plugins.
7. Sorting through Activity Monitor to find anything else running on my CPU of consquence--I don't think so.
8. Confirming good ping and down/up speeds on Speedtest.net with my iPhone
I know little about networking, but I'm learning. Any other suggestions? Why does the MacBook behave differently on this network?

Thank you for the suggestions. I agree that my ISP rep looked a little confused by my problem. He was comfortable using Terminal (at least for basic network queries--more than I know how to do).
Although I physically have the ISP's router in my apartment, the ISP has changed the password, and I'm unable to change channels (though that shouldn't explain the peristent problem on ethernet). I've tried restarting it many times, including unplugging it.
I just emptied my trash (and restarted the computer). 500gb HD, 24gb free. No change in performance.
You're running out of HD space. That's the problem.
Empty the trash in the Dock as well as iPhoto’s trash!
Open up your application folder & go through all your apps. Trash all the apps you no longer want and/or use.
An easier way to do this is to open the Application folder in list view & press the Command+j keys.
In the the dialog that appears, click the "This Window Only" button & the "Calculate All Sizes" check box.
Wait a bit until your file & folder sizes have all been calculated, then click the "Size" column to sort your apps from the fattest to the most anorexic.
Get rid of all your photo files you don't want and/or need. Same goes for those pics off the websites you downloaded (gifs, jpegs, etc.). Or transfer/move them all to a photo/movie storage site like ImageShack and Photobucket, 2 of the most popular FREE storage sites.
Get rid of all your video & music files you no longer view and/or listen too. Especially, if you already have the actual CD/DVDs or you can later redownload from a website. Or transfer them all to a FREE video/movies and/or music storage site.
Use Spotlight to make sure you got rid of everything. You can even trash directly from Spotlight! Better yet, download this FREE software called Find File. This app puts Spotlight to shame (works w/Mountain Lion).
Drag what you don't want and/or need to the trash. Better yet, download this neat little shareware app *demo* called AppZapper. It basically does all the work for you by not only trashing the apps but the apps preference files, caches & all its associated files.
Another software that does the above is AppDelete. Best of all this software is free!
Burn what you want and/or need onto CDs or DVDs. Not everyone has the luxury of purchasing an external HD and/or the system requirements for iCloud to store their "stuff.”
Dropbox is a free storage utility to check out.
You can check with your ISP to see if they offer *free* storage space. Most if not all do now-a-days. There are thousands if not millions of *free* storage facilities on the web also. Use your favorite search engine to search them out as they come in different storage sizes to fit your needs & wants.
Check for duplicate fonts.
Applications>Font Book
Select “All Fonts”
If you see any “black dots” next to any fonts this mean you have duplicates and/or multiple versions of these fonts.
To clean this up, select a “black dotted” font or the Apple + *click* to select multiple dotted fonts;
Edit>Resolve>Duplicates.
What the above does is turns off the duplicates & multiple version fonts. Not delete them.
More than likely the “extras” were installed by other programs and/or other users.
Clear out font caches
Use FontNuke. It does all the work for you. And, best of all it’s *FREE*.
Printer Drivers
Get rid of all the printer drivers you don’t need & use except the ones for your *current* printer(s)/scanner(s).
HD>Library>Printers Folder
If you accidently threw something out that you needed for your printer/scanner it can be easily obtained from the manufacturer’s website and/or from the CD that came w/the printer/scanner.
Garage Band
Has about 1GB of loops stored. Get rid of some some them. You surely don’t use, like and/or need them all.
HD>Library>Audio/Apple Loops>Apple>Apple Loops For GarageBand
Or just get rid of the Garage Band app altogether if you don’t use it.
Get rid of extra languages
Strip your computer down to your “native” tongue.
You can do this with a *FREE* utility called Monolingual. Another app that apparently does all the work for you. I’ve never used it. However, a lot of users here swear by & recommend it highly.
However, there is a warning for *native English speakers*. Make sure you keep BOTH English and English (United States).

HP Laserjet M1132 MFP is too slow over the network!

Hi,
My HP Laserjet M1132 MFP is too slow over the network!
I have connect the printer to a windows XP 32bit SP3 using UBS port. The printer works fine on the local computer but when sharing it over the network it works too slow, for example with print test page it takes about 45 seconds to print and for other documents it takes much longer time.
I have installed the latest driver form HP website and upgrade the firmware it the latest version.
It happens on other Windows XP machines as well.
I connected the printer to my laptop (Windows 7 64bit) and it works fine (No delays over the network) and it seems that this problem have some relations with the windows XP Driver.
I have used local port trick on remote machines (instead of regular method) like this:
''add a local printer;
'new port'
'localport'
\\XPcomputer\HPPrinterName as port name
but still nothing!
There is nothing wrong with the network, we use to use a Samsung printer on the same machines over the network with no problem.
I Really appreciate your HELP!
This question was solved.
View Solution.

BEHZAD_T, how is the printer connected to the network (wireless or Ethernet)? If it is slow wirelessly, I would suggest trying to connect the printer to your router with the Ethernet cord and install it to the networked computer that way.
Another question is, relatively speaking, how close to your router are the Samsung printer and the HP printer? Depending on the distance (and what stands between the devices) there can be a lag between sending a print job and it being received by the printer.
Let me know!

Slow on the network?

Anyone have any thoughts on this problem?
I have a new workstation connected to an existing Windows network. Everything seems to work just fine... except Bridge, which takes about a minute to access any folders on other computers attached to the network. Bridge works fine on folders on my computer--and the Windows navigation tools work fine on the other network computers... just Bridge + the network is the problem. And a frustrating one on deadline! Ha!
I have tried all the obvious fixes (that I can uncover on the forums, anyway...) and am wondering if anyone has any experience troubleshooting this kind of issue.
Thanks,
Joe

Hi...
I'm testing Bridge as a video asset browser on our network and I'm seeing similar behavior.
I've developed a work flow to create low bandwidth proxies of source media and I'm on a 1.0 gig pipeline, so bandwidth is not the issue.
I have also background cached all the thumbnails prior to browsing tests. In my case I have also pushed the cache file out to the folders.
In using Bridge, it seems there is a huge lag from the time I make the request to preview a source to the time Bridge actually access the network.
During this lag, the application goes into "Not Responding Status" (Windows Task manger).
Once it starts to access the network, I will get access to the material in quick batches, then the connection will time out again, and the application will become non responsive.
I have the option in my case to mount the drive as a local volume or a network volume. Most everyone on my SAN will be able to do the same, but some clients are attached only via ethernet.
I'll see if behavior as local drives is better.
Help! I want to believe this can work, but I won't deploy it unless I can generate consistent and reliable performance. :)

Why does my Iphone 4s keep dropping the network

Hi there, my 4s has just started dropping the network (Vodafone) today, it has no service for 5 mins or so then full signal for about a minute. It seems to be repeating this over and over.... Has anyone any similar type of problem? If so can you help with a solution? It's driving me nuts!

Settings > General > Reset > Reset Network Settings.
Restart the device.
Replace the SIM card.
Address issue with carrier regarding their network.
Has any of the above been done?

Why is my video sounds slower than the video playing

Why when I record a video the sound starts way after the video has been started

Macs normally slow down a bit over time. Uninstall any unneccary apps and try keep the ammount of hard drive space free more than 50%. To find out how much hard drive space you have left click the apple logo in the menu bar and click "About This Mac" Then click on "More Info" and after that click on "Storage".
Also, try to see if there is anything wrong with your hard drive. To do so click on the liitle rocet icon (launchpad) in the dock and click on "Utilities". Then click on the "Disk Utility" app. Then select "Macintosh HD" in the left menu/ Then click "Repair Disk Permissions". Wait for it to finish. Then click "Verify Disk". Wait for it to finish.
After that, if Disk Utility says you have any hard drive errors, click "Repair Disk".
Lastly, try a good old restart!. This always speeds up a Mac.

WHY AFTER EFFECTS STILLS SO SLOW IN THE NEW MAC PRO?

I have the new mac pro with this settings:
3 GHz 8-Core Intel Xeon E5
64 GB 1867 MHz DDR3 ECC
AMD FirePro D700 6144 MB
Software OS X 10.9.2
And the AE performs slower than in my old mac pro. I have set the preferences as seen on all those tutorials on this site, I have an SSD external disc for cache files, memory and multiprocessing settings correctly...and previews are very very slow, and I can not even render a single comp without waiting 10 minutes. I am very disappointed and frustrated with this situation...
Am I missing something?

I don't understand why it's even up to the user to figure out what settings are best. Isn't the application in a vastly superior position to know what its resource constraints are at any given moment? Instead I have to try rendering a couple of comps, kill the render, fix the render queue since AE STILL doesn't offer a graceful way to quit and resume renders.
I have to say that one of the attributes of AE that consistently disappoints me is multiprocessing and its accompanying memory management policies. I regularly produce hundreds of network graphics at a go, and I can never reap any benefit from multiprocessing, because AE has to load the entire project into each core, instead of just loading the comps it needs to render at any given time. Similarly, a project that requires 400 heavily-automated versions (a regular occurrence for some of my Latin America clients, where graphics have to be versioned for multiple feeds and languages) can simply choke AE. If it could load this stuff into memory on-the-fly (or at least offload some of it when memory gets tight), this wouldn't be a problem, and I sincerely doubt the performance would be worse than it is now. This is on a previous-gen Mac Pro with 48 GB RAM, so, while not strictly state-of-the-art, it's no slouch.
Heck, even opening some of these projects just to browse their contents is a painful 30-minute process, as AE apparently has to not only load everything into memory before I can even do anything, but, judging by how it hangs for many minutes at 99% on the progress bar, it also seems to be evaluating all the expressions in all the hundreds of comps (presumably so it can render the project thumbnails). And yes, I've tried splitting the projects up, but this leads to its own complications, particularly when revisions come in a week or two later.
I don't want any of this to sound overly negative, since I know AE has a small team and this sort of stuff isn't trivial to implement. I do appreciate this application and all it does, particularly for me creatively and professionally. I just get a bit tired of seeing new releases come every year and this stuff seems to go unaddressed.

Why is Photoshop CS6 extremely slow with the brush tool using Wacom pen?

Could my wacom tablet be the issue? The psd processor spins not stop until I pick up the wacom mouse and click on an adjacent layer then back to the layer I was working on. Then the wacom pen work with the brush tool. This seems to happen when every time I pick up the pen and go back to the brush tool.

First, sorry it took so long to reply. Have been a bit swamped. What I mean by the psd processor, is the balls that rotate kind of like the SBDO when the app is executing a paint stroke. So I tried your suggestion, mad a new file 7w x 5d at 72pi, set the brush to 25px at 100% hardness and made a stroke with the wacom pen. It worked fine. The issue is working in large files say around letter size at 300dpi or large format graphics for trade shows at 150dpi. These files can range anywhere from 6ft x 8ft high to 16ft w x 10 ft h for an example. So painting in a channel mask or retouching using the brush tool in airbrush mode is painfully slow. I've found that while this little psd icon is spinning, if I take the wacom mouse, click on an adjacent layer then go back to the layer I was working on and resume with the airbrush, the problem subsides. It seems this spinning thing happens when I initially start using the brush on a layer or layer mask. Do you get what I'm trying to explain?

Server slow in the network

Hi boys and girls.
I have a little problem. My server (router, ftp, http etc.) is realy slow when Im connecting within my network to it. If I connect to it with ftp I only get a speed at around 20kb/s, and thats in the same network, not over internet! Same thing with ssh, and so on.
Whats the problem?
Im using vsftpd 2.0.3, openssh 4.2pl, Arch's kernel 2.6.13, and a iptablesscript called firewall-jay (dont think that makes any difference).
And no, I have no real load on it, so that should matter either. I have tried using different computers with different os's and diffrent ftp-clients.
Please ask if you need more information.
EDIT
Something I forgot to mention and mentioned in my second post, from the internet I get around 2MB/s (~20mbps), with that computer acting as a router. That makes it even wierder in my eyes.
And I can also add that I can find nothing that is worth mentioning in dmesg.

Could a broken nic result in this things? In my opinion it should be problem with both internet and lan then? I changed nic to eth1 (that's the one my sisters computer is on usualy). And now my computers get a decent speed.
I'll wait for some people to coment my iptables and tcpdump before trying to buy a new NIC (I need one anyway...)

Why won't my Airport Expr extend the network created by my Airport Extreme?

I have a 802.11n Airport Express that creates a great, solid wireless network in my house. The signal is pretty weak in the basement though so I thought I'd use an old 802.11g Airport Express to extend.
However in the Airport Utility > Wireless settings for the Express, no "Extend a Wireless Network" option exists.
I then tried setting up a WDS network and made the Extreme the WDS main and entered in the mac address of the Express as a WDS remote, but once the Extreme restarts is shows a WDS error that states "This Apple wireless device is set up as part of a WDS network but no other wireless devices were found."
Am I doing something wrong? Do I need a 802.11n Express to play nice with the 802.11n Extreme?

However in the Airport Utility > Wireless settings for the Express, no "Extend a Wireless Network" option exists.
In order to extend the 802.11n wireless network of your 802.11n AirPort Express Base Station (AXn) you will need another AXn. You can extend the wireless range of the AXn with the older 802.11g AirPort Express base Station (AX) but only for 802.11g. This is why your are not finding the extend option in the AirPort Utility for the AX ... and why you must configure the two for a WDS.
I then tried setting up a WDS network and made the Extreme the WDS main and entered in the mac address of the Express as a WDS remote, but once the Extreme restarts is shows a WDS error that states "This Apple wireless device is set up as part of a WDS network but no other wireless devices were found."
Most likely, the problem is that the distance between the two AirPorts is either too great or there is too much Wi-Fi interference between them to establish the WDS. I suggest that you first try configuring the WDS with the AX in near proximity of the AXn to verify that you can successfully create the WDS. Once verified move the AX to the desired location.

Why can i see my laptop on the network from my tower?

ok, my laptop is sitting next to me with the sharing preferences turned off. it is hooked to the internet via LAN (not even my internet router), and my tower is here hooked up via ethernet to my own modem. so my laptop is on the internet through a completely different internet connection, and my tower is hooked up hardline to my own modem. when i'm on the tower and go to network, i can see my laptop and look through all the files. why is this? i want my laptop to be blocking everyone.....? what do I need to turn off? thanks

Hi Brian,
Along with the other user's excellent suggestions,
I'd also go in to the laptop's sharing preferences, and toggle them on and off again.
And then restart that mac.
PS-I'm not quite clear on your network arrangement (LAN, not router....ethernet via modem...hardline? huh? :/...)
What precisely do you mean "completely different internet connection?
Any of these guys on a wireless connection?

Why is my internet so slow on sprints network

can someone tell me

There have been lots of complaints about this. Talk to Sprint. The problem is their network.

Why does it take so long for the network in my house to come up???

I am having a hard time getting on to my home network (to shar files between computers!). It takes up to an hour to connect! Is there something in settings that I should change or is this normal. Please help!

Thanks @pdroth. I did a quick Google search of DB indexing. I'm not sure I found exactly what you were referring to but I see where you're going with it. I can understand that indexing my database of stored photos can be time consuming. It's frustrating that the space can't be recognized as being free more quickly.
I notice that some items I delete seem to free up the space much more quickly. Removing an app entirely or deleting from my Music generally shows up as available space in Usage pretty quickly.
Deleting a photo or video from the Camera Roll will take MUCH longer, so I guess that has something to do with the indexing process you are referring to.
I'd like to point out that when I run out of space on an SD card on any budget point and click digital camera that I can quickly delete a picture or two and INSTANTLY be able to take a couple of new photos in their place. I guess I just have that same expectation for the $500+ engineering marvel I have in my hand right now.
Thanks for chiming in.

Why did an iBook purchase only download the first chapter?What can I do about this?

is it possible you only downloaded the sample? the cover image for the book will have the word Sample in a red banner across one of the corners.
if you actually purchased the book and only received one chapter, then there should be a link in the email that iTunes sent you to dispute the purchase.
