Very slow internet / safari

Hello,
My internet has been very slow recently -- both when I am running off my server and others. Does anyone have any suggestions of what to do?
Many many thanks Melissa

A bit more info needed Melissa!
Does Firefox do the same?
How are you connected & such?
At this point I think you should get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, Reboot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least if it doesn't fix it, it'll eliminate a few questions.

Re: "Very Slow Internet On OSX 10.5.5"

Hello all,
I am creating my own thread in response to ones like rogerjth's July 2008, the subject of which was "Slow Browsing with safari 3.1.2 - Any issues to watch out for?" and Roippeli's from Sep. 21, 2008, the subject of which was "Very Slow Internet On OSX 10.5.5 / Works Fine on XP. Since many people on the forum have been having the same problems and, like myself, have been unable to resolve them by the same methods that seem to have fixed the problem for the majority of people (hence the issue topic being marked "answered" because the topic was indeed answered, but only for the OP), I decided to start this thread again.
I have been having the same problems as Roippeli and rogerjth for over a week now, and despite having searched the forums exhaustively, I am unable to fix them. I have tried every suggestion, including all of those made by Klaus 1 (emptying cache, resetting Safari, deleting specified files from Home/Library/Preferences and "/"/Safari, adding DNS numbers, scanning for trojan viruses - of which there were none - creating an OpenDNS account and configuring both my router and my PB to utilize OpenDNS), which seem to have solved the problems for many. However, after a short period of subtle yet marked increases in speed, I am back to the same place that I was before taking these steps. Intermittent connection, slow speeds, the works. I'm now ready to smash the router. Help!

same problem here on a macpro. but only since today, i updated to 10.5.5 a week ago or so when it came out and had no problems until today. the moment i started my macpro internet connection was very slow (with safari, firefox & mail), but the airport network itself seems to be fine though (tried by copying files from a network disk).
everything else connected to the same network works fine (iphone, other macs without 10.5.5)
i posted in a german forum too and there are some others having the same problem.
the question is : why today ??? i didn't change anything serious lately.
i'm currently trying to download the combo update again and safari standalone but i get one timeout after the other.
also tried to repair rights, p-ram reset, safari reset - nothing helped.

I have very slow internet even though my provider says the speed is fast

I am experiencing very slow internet even though my provider says that my speed is fast. The uploading of a page takes long to complete

If Safari is getting very slow:
(Presumably you regularly empty your Safari cache by deleting the following file:
Home/Library/Caches/com.apple.Safari/cache.db
and clear your History)
Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security, (including anti-phishing and redirects) (Full information about Open DNS is here: http://www.opendns.com/home/nobloat ) and further independent information can be read here:
http://reviews.cnet.com/8301-13727_7-57338784-263/free-dnscrypt-tool-enhances-ma c-web-security/?tag=mncol;txt
and here:
http://www.macworld.com/article/1146064/troubleshootdns.html?t=234
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
http://support.apple.com/kb/TS2296
If your computer is part of a network:please refer to this page: http://www.opendns.com/start/best_practices/#your_network and follow the advice given.
If you use a Router, make sure it has the latest firmware installed.
One reason for a slowness in page loading may be the 'DNS Pre-fetching' feature of Safari 5.x as is described here:
http://support.apple.com/kb/TS3408?viewlocale=en_US
You can cancel DNS pre-fetching by going to Terminal and typing:
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
You have to restart Safari for it to take effect.
If Safari seems to hang for ages:
If you have a lot of tabs open and/or a lot of pages running Flash, Safari can sometimes 'hang', requiring a restart of Safari. This can often be inconvenient, and as it is rarely Safari itself that is hanging but merely one of its plug-ins, usually Flash, there is a way using Terminal to restart the plug-ins (without restarting Safari and losing your tabs) by quitting the WebPluginHost process:
Open the Terminal from the Utilities folder in /Applications and type
killall -9 WebKitPluginHost
Note that this command kills all Safari plug-ins, not just Flash. All plug-ins should start back up when you reload the page.
Then go back to Safari and refresh any pages that were using the Flash plug-in. This also fixes the Beachball of Death. Try this whenever Safari gets slow or freezes. The later versions of Flash 10.1 onwards appear to have improved the situation somewhat, but haven't completed eliminated it.
For this and other reasons Apple switched their websites to HTML5 in January 2011:

Very Slow Internet Lion (This one is for the "Apple Network Team")

hello,
i'm joão from Portugal, Europe.
a couple of weekends ago i've updated three macs to Lion.
2009 MacMini, 2007 White Macbook, 2010 iMac 21".
problems? only with the iMac.
no connection drops but slow slow slow very slow internet. wired, speedtest marked 15Mbps download. wireless? 1Mbps, 0,3Mbps, 3Mbps, very unstable.
with Snow Leopard everything was ok.
tried every solution from every site and finally got it working flawlessly.
tried clean install instead of update.
tried new dns servers.
tried disabling ipv6.
tried remove wifi interface then add it again.
tried service order.
tried PRAM, NVRAM, SMC, you name it, reset.
tried removing preferences folder.
tried different browsers -> same symptoms.
tried disable/enable airport.
tried 10.7.1, 10.7.2, combo, delta.
tried router's firmware update.
tried putting the computer closer to the router.
tried resetting the router, factory defaults.
tried changing router's channel.
tried disabling router's firewall.
tried watch router's event log, nothing suspicious.
tried disabling router's wep password.
tried pinging a site for a couple of minutes, 2% packet loss.
tried hundreds of pages and forums...
during this attempts, macmini and macbook showed very good wireless internet speed.
iMac? slow, slow, slow, slow, slow, like seeing gmail's loading screen for more than one minute...
again and again speedtest 1Mbps, 0,3Mbps, 1Mbps, 1Mbps, 0,3Mbps, 3Mbps.
discovered the pingtest utility in the same site and iMac's ping was grade C, grade F, grade D, with big values...mac mini and macbook were alwas grade B, with low pings (imagine 25ms on them vs. 138ms on the iMac).
i was fed up with the situation, every week tried and failed. iMac's owner was wanting to get his Lion money back and stick to Snow Leopard again. imagine recent Windows switchers thinking they went back to the same situations....
but then i found this website. and then realised macbook and macmini's wi-fi were both powered by a broadcom chipset. iMac's was powered by an Atheros chipset! did what the guy says on that site (replaced Lion's Atheros kernel driver by the one on Slow Leopard), and now everything is perfect, like on Snow Leopard. very good speed.
what a relief. thank you sir.
hope it can help you.
hope it reachs apple's network developers...this is not good, you can't fail on something so simple and essential as decent wifi quality...

humm...
i've clean installed one macbook (late 2008?) and one mac mini (early 2009) both with broadcom adapters and both of them were ok, after the install.
so, speedtest and pingtest are websites (speedtest.net and pingtest.net), both test your internet connection with the help of a 'local' server. it's useful, for instance, if you want see if two different computers connected to the same router have the same connection quality.
so if you can connect to some routers nicely and you have problems with your router, to me, it seems like you have some problems with the connection between your computer and the router.
an old router might bring you problems (there are some advices on the internet to change router's channel and so...), i would recommend to see if motorola has some sort of firmware update to your router. if you don't have complex router configurations, you might try to reset to factory defaults (search the manual). that, once, fixed a problem with a smc router and two macbooks (one, older, could connect easily, the other wouldn't connect to the router).
if that atheros driver trick, resolved your issue, that's strange
make sure broadcom isn't your ethernet adapter and not your wireless adapter
did you resetted your pram and smc? do you have Mac OS 10.7.2?
i hope you can figure that out.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Hi ..
Better to troubleshoot Yosemite.
Not enough free storage space can slow your Mac down.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space. OS X Tips Where did my Disk Space go?
As for Safari, might be a cookies, cache, extensions, or plug-ins issue.
From your Safari menu bar click Safari > Preferences then select the Privacy tab.
Click: Remove All Website Data
Then delete the cache.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari to test.
If that didn't help, from the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.

Very slow internet (Wifi) on my mac mini late 2012

Hey, I have recently experienced very slow internet (Wifi) on my mac mini late 2012. On other mac's and computers the internet is working well. I cannot change the channel of the router (what I found out to be the only solution here), because I live in dormitory. Should I try to restore OS? What would be other possibilities? Is it OS or mac mini issue?

If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.

Very Slow Internet Connection and Backups

I have had a Time Capsule for some time now (1st generation) and it has caused nothing but headaches. I have put up with it for some time but I have a very slow internet connection and cannot leave Time Machine on or it bogs down my machine, so I only backup periodically. Specifics are provided below.
I have a poor internet connection to begin with. When plugged in directly either to my modem or through Ethernet to the Time Capsule, I get download speeds of ~ 2.9 Mbits/sec download, 0.7 Mbits/sec upload. When connected over wireless, the speeds drop to about 0.6 Mbits/sec download, 0.6 Mbits/sec upload. I feel like I am working on dial-up. I have both a Mac and a PC, and speeds are the same on both, so it does not appear to be a computer issue. I have played with various settings in the Airport, including how connected (b-n or n only), DHCP settings, etc, but nothing makes a difference. Any suggestions?

Welcome to the discussion area, bigbrianb!
Have you downloaded a utility like iStumbler to get a look at the signal strength and noise on your wireless network?
iStumbler will display most of the other wireless networks around you, so you'll have an idea of the competition for unused channels. Ideally, you want your network to be on a channel that is at least 4-5 channels away from any other network to minimize the chances of wireless interference. Is that the case there?
Your signal strength should be 50% or greater and noise less than 10% for a good quality connection on your network. Is that the case there?
There are more things to test, but this will get things going.

Im having a very slow internet connection on my macbook pro??help pls

hi
i bought a macbook pro back in summer 2012 and it came with mountain lion but since then Im having a very slow Internet connection. I have one router at my home. my other PC works fine with the Internet even my iphone 4s is way faster with same wifi connection. when I download a TV show on macbook from itunes its takes about 40-50 min to download fully but on my phone or PC it usually takes about 18 mins. and also when I try to watch a hd clip on youtube, I need to put on lowest quality in order to watch it without lagging or stopping midway.
does anyone else have this issue or I have to talk crap about apple product from now on???

Hold down the option key and select the Wi-Fi menu in the menu bar. What values are shown for the following?
PHY Mode
Channel
Security

Very slow internet after installing 10.5.3

Hello all, this is the very first time I have encountered any problems with my Macbook and I am hoping I can get some help here.
About a month ago I came home from college and hooked my Macbook up to the wireless router at home, everything was running fine. We have fiber optic internet so usually my speeds are blazing fast. Recently however I installed the 10.5.3 update and now my internet speeds are very dismal. I am having trouble getting my Macbook to connect to the router at all, much less load any web pages.
I have taken an ethernet cable and plugged my Macbook directly in to the router to see if things load any faster, and unfortunately things are still just as slow over a wired connection. After typing in a URL you will sit there at a blank web page for about 45 seconds to a minute before it even starts loading the page, and when the page does load it takes forever to pull up and images take even longer to display. If it helps at all our router is a dlink DI-524 wireless router.
I was browsing through these forums yesterday to see if I could find a solution to my issue. so far I have tried the following:
-set router to broadcast in G mode only (instead of mixed mode)
-removed encryption from router
-tried various encryption settings (64 bit WEP, 128 bit WEP, WPA, etc)
-updated the firmware of my router
-created test account on my macbook, opened internet browser on it, everything still runs slow
-deleted cache for safari/mozilla as well as the .plist files, still slow internet
when i called apple the agent suggested putting in my os X CD and do an archive and install, i did and once i was set back to os X 10.5 i was unable to connect to wifi at all, and wired connection over ethernet seemed just as slow as before. when i check for apple updates the 10.5.3 update was my only option, i couldnt choose 10.5.2 so installing that would put me back where i was before.
in the end i set my computer up last night to do a restore from my time machine backup. my machine has been restored to the backup i created just before i tried the archive and install, so im back to running OS X 10.5.3 now.
I'm sorry this post got so long, I just wanted to make sure that I included details of what I've done so far. Again I would like to stress that I am having this problem on my macbook even with my computer hooked directly to the router with my ethernet cable. (using that same cable and hooking up any one of my windows computers in the house results in fast and effortless web browsing so i know the cable is good)

It's not a matter of Mac OS X being "picky" but rather various ISPs not keeping up with changes in the DNS standard.
In the most recent case, 10.5.3 had to revert to a previous method of performing some DNS lookups because various ISPs hadn't bothered to update their servers to handle what has been the recommended way of handling lookups for the past eight years.
OpenDNS also has done a lot of work to make sure their DNS servers work as fast as possible; ISPs have absolutely no incentive whatsoever to provide fast DNS services.

Very slow internet access..... - interesting issue !

I have 3 computers at home: PC XP, PC Vista and a new imac 24'' since 4 weeks....
As side comment I'm disappointed in Apple... I expected much more… more issues than Vista seems….
10.4.11 + Safari 3.0.4 + Firefox.
Internet on my Mac is very slow. On the same network (wireless with WEP 128) when I enter a new page on my PC and Mac at the same time it take to the Mac approx 5 time more time to display (safari or firefox)…
On safari I have empty the cash and “reset safari”…still the same….its dam slow for Internet access. I also removed the Wireless encryption but still the same….
Does somebody have a clue what it could be?

The DNS is coming from the dsl provider. Very often your router simply gets the dns automatically. With Leopard, I suspect some of the settings are such that things time out before the dns gets through. What I did was look up what the actual IP number of the dsl providers dns was. I added the IP number of the dns provider to my router. So far that seems to have solved my WiFi delays with Leopard (although that could just be a co-incidence).
Exactly how you add the IP number to a router is router dependent. Mine is a netgear, and you do it through a web page link to the router's IP number (which will be listed in the manufacturer's handbook). Generally something like 192.168.0.1
Hope that helps.

Apple Community pages very slow in Safari.

Lately I am finding moving between Apple Community discussions has become very slow, sometimes irresponsive. It is not a permanent feature; it tends to be like that for varying periods of time ... then reverts to normal. My internet connection is good and refreshing the page ... well, it just doesn't.
Would be glad to hear from anyone with thoughts on this?
Thanks. 71.

Same thing happens to me. I look at many posts and discussion and then it no longer responds. I can open a tab and go to any website and it works great but the discussions.apple.com remains nonresponsive. I quit safari and start Safari and discussions.apple.com works fine again.
I haven't been able to figure out why.

Suddenly VERY Slow Internet On Macbook Pro

My MacBook Pro is less than a year old, running Snow Leopard 10.6.7. A few days ago, the internet suddenly became very, VERY slow. My computer says it is receiving a full signal, and my girlfriend's computer (a Dell, I might add) is on the same wireless network and is working great. I have tried everything suggested to me when searching for the problem online: I've reset my router and modem (but again, my girlfriend's computer is working well on the very same connection and my MacBook claims to be getting a full signal), checked for software updates, emptied Safari's cache, reset Safari, disabled plug-ins, tried Chrome and Firefox (the problem persisted), scanned for a DNS changer and viruses/spyware (the scan came up clean), added open DNS servers, reset my TRAM, repeaired disk permissions and have restarted throughout this process. I cannot trace this changed internet speed to anything - I have no idea what has caused it or how to fix it. Please help!

Hi...
Try Starting up in Safe Mode
That deletes system caches that may help. A Safe Mode boot takes longer then a normal boot so be patient.
Once you see the Desktop click the Apple menu icon top left corner of your screen. From the drop down menu click Restart.
If that didn't help, try uninstalling Sophos > http://help.bol.ucla.edu/app/answers/detail/a_id/879
Then try your browsers. It could be the security software that's slowing your browsers down.
If that helps, you could try a different anti virus software such as ClamXav. It's free and Lion v10.7 compatible.

Slow internet safari mountain lion

After installing the upgrade to mountain lion my internet connection using safari is very slow. Anyone with the same problem and a solution?

I was able to resolve the problem by disabling my WiFi on the iMac and just using the ethernet.
Maybe ML updated the WiFi in some way that is causing issues between the cards on the machine and the WiFi routers/access points. I've seen this happen in business settings when firmware updates get applied to the WLAN system that cause issues with some wireless adapters. Usually, updating the driver on the wireless adapters can fix the problem. This may be a reverse case.
For reference, I'm using a Linksys 4200 with the current firmware version 1.0.00. I've checked the support site and found that 1.0.04 is available. I'll upgrade the firmware and test it out to see if that makes a difference.

IOS 5 VERY Slow Internet on iPhone 4

Ever since upgrade, non-wifi internet connection is very slow and often times out. This happens even with 4 bars.
I've tried resetting. This was never an issue prior to upgrading. I need non wifi internet for work and this *****!

I've had this exact same problem.
I've done the following things to try to fix it:
*Clear Safari Cookies, history and cache
*delete unused apps
*Hard Reset
*Reset Network settings
*Double Hard Reset
When I did a speed test twice in a row I got:
1. 0.00 Download 0.66 Upload
2. 1.4 Download 0.00 Upload
This shows the spotiness of this connection issue.
I hope we get some answers about resolving this terrible issue.
