Slow internet on Macbook

I have a new MacBook Pro. The internet is exceptionally slow.

Wireless? check your router and make sure its not using a channel conflicting with others in the area,

Slow internet with macbook pro retina (late2013)

The longer I'm having my new Macbook Pro Retina, the slower it gets concerning the internet.
There is sometimes no speed at all... I have to wait about half a minute to start the loading of for example an ebay site.
As I use my old Macbook Pro (late 2009) right beside the new one, I have the perfect comparison. The old one is fast as ever. Even my Iphone is much faster in our home WLAN. The new one just works and works on heavy loading site after site.
Shouldn't it be the opposite way?
Has someone the same problems?
Any solutions?
Greetings from Germany,

1. Power cycle
     Power off the router. Unplug it from the wall. Wait a while.
     Plug it back to the wall. Power the router on. Wait until all the lights are lit properly.
     It will take a   while.
     Restart the computer.
     Start up in Safe Mode

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.

Substantially Slower Internet - Two MacBook Pros on Network

I have recently acquired a MacBook Pro, running Os/x version 10.5.8, and the internet functionality is noticeably slower than other systems on the network.
Both my desktop PC (running vista) along with my roommate's MacBook Pro surf/download at high speeds, as provided by our ISP (comcast). However, this particular machine can take anywhere from 20-30 seconds to open a basic webpage that would open instantaneously on either of the other two systems. Download speeds are often 10 times slower.
Any solutions to this particular problem? I've done a bit of research on google, and found some aged inquiries that were similar, often with multiple possible "solutions", but usually applying to an older os/x.

No.
Also, why would that slow this machine but no others were that the case? (This question is purely hypothetical. Torrents are not running)

Slow internet with Macbook Pro

My desktop connects fine in downloading and browsing, but my Mac BookPro is sluggish to the point where I have to refresh just to get it to do anything. Anyone have ideas on why this is? Or simple solutions?

I think this is related to the MBP and possibly 10.5.2. I have just tested my connection speeds on my APEBS on my iMac 10.4..11 and PowerBook G4 10.5.1 and all had reasonable good connection speeds (using speedtest.net). I'm Jupiter, FL and I tested to Jacksonville, FL, Portland, ME, Colorado Springs, CO and San Jose, CA. The download/upload speeds on the iMac were 2836/386; 2801/401; 2577/362; 2474/398. The download/upload speeds on the PowerBook were 1827/365; 1326/406; 1557/319; 872/399.
Compare those to the MBP 10.5.2 2111/45; 1124/46; 930/125; 533/7
You can see a real problem with the upload speed (which is why I keep getting the "Safari can't find server" message).
Now compare these speeds to these when I take out the APEBS and hook the MBP directly to the DSL modem (Westel 6100). 1147/382; 6134/413; 5005/388; 4388/498
Vast improvements in both the download and the upload speeds.
I'm now using my iMac because the MBP is not usable with the internet with the APEBS Wi-Fi (slower than the old dial-up)

Slow internet on mid 2011 macbook air

So my internet is intermittently slow on my macbook air. This has been happening for many months although I cannot remember if it corresponded with upgrading to OS X 10.9. It is sporadic and I cannot identify any precipitating causes or solutions. My internet speed will just randomly drop and then eventually will correct itself where I will have the 15mbps download speed that I am paying for through my ISP. When the internet speed drops I will average 0.6 - 1.5mbps on speediest.net. This seems to be only isolated to my mid 2011 macbook air as my other laptop - a PC, and my iPhone show regular speeds. I have called my ISP and router customer service departments many times with no help. I have replaced my wireless router. Please help.
Nothing has worked. I have tried everything that I can think of including:
1. Installed all OS updates - this seemed to work for about a day and then back to the same slow internet speed
2. restarting the computer
3. restarting in safe mode
4. uninstalled and reinstalled the wifi network
5. restart modem and router
6. replaced router with a new model
7. changed wireless security settings on wireless router and channels'
8. changed DNS to google 8.8.8.8 and 8.8.4.4
9 installed onyx and cleaned system
10. ran virus check
11. disabled safari plugins
12. deleted preferences.plist and networkinterfaces.plist
13 turned off bluetooth on mac
14. turned off wifi on all other devices
15. disabling and enabling wifi networks
16. run diagnostics on wifi - normal

run diagnostics on wifi - normal
It's not clear if that was the result of using Apple's Wireless Diagnostics. It may supply some additional helpful information.
To use it, hold an option key while you click your Mac's Wi-Fi icon, and choose Open Wireless Diagnostics...
The following authentication dialog will appear:
Authenticate with your Admin password, then click the Continue button in the following:
The network analysis and diagnostic tests will take several minutes to complete:
When it completes, if your wireless network is functioning properly the following will result:
If something is amiss, supposedly the results will be different and you will be presented with helpful information.
Assuming your connection is "working as expected" select Continue to summary and click Continue:
Ignore the pre-populated text field, which is provided as a place for you to type in additional information should Apple ask for it in the course of obtaining technical assistance from them. Apple has no way of knowing where your router is located in your home, and certainly doesn't know if you even have an upstairs bedroom closet.
Click Continue.
The next step will also take a few minutes:
When it finishes, you will be presented with a summary that may or may not be useful to you. Let me know if it is.

Slow internet connection via AirPort on MacBook running 10.5.7

The internet connection via AirPort on my MacBook is frustratingly slow, and I have no idea why.
I have an AirPort Extreme connected to a Virgin Media cable modem, a new iMac and a two year-old MacBook, both running 10.5.7. No problems at all with the wireless connection on the iMac - I get the full near-10Mbps download speed I'm paying for, despite the fact it's at the other end of the house. Not so on the MacBook, where I get barely 2Mb, even if I'm sat next to the router.
I've had other AirPort problems since the 10.5.6 update - notably one common to a lot of people on here, it seems, of the AirPort dropping the wireless connection every 2 mins. This was only 'fixed' by the fairly drastic workaround of essentially abandoning my user account and connecting via a different one.
For the slow internet problem, I've tried resetting the PRAM, turning off my cordless landline phone, changing the wireless channel - to no avail. I can't test the wired connection as my MacBook doesn't recognise my Ethernet port, it would seem, and hasn't for a long time.
Can anyone help? Thanks in advance.

I assume that you meant NVRAM as PRAM is not used with Intel-based Macs. Regardless, network settings are not stored here and resetting it won't really help. The fact that your MacBook is not recognizing the built-in Ethernet port is telling me that may have an issue with the system board ... that may be showing up as poor performance with the AirPort as well. I suggest that you take your MacBook in to your local Apple Store to have them take a look.

MacBook Pro and Wi-Fi Slow Internet Connection

Hi There,
I just got Macbook Pro. I am new Mac user and ran into strange problem. when I connect to internet through Wi-Fi the speed is really awful in comparison with my other windows based laptop at the same time.
How could I solve this problem? I mean, is there any specific setting I am supposed to do to overcome my slow internet speed?
Thank you

I did test my internet speed through site " www.speakeasy.net/speedtest ". There was not any big
difference between my macbook pro and windows computer internet speed. Major difference is about webpage loading time. Could you please let me know what could I do to figure it out?
Your ISP's DNS servers are not communicating with your Mac properly. This is a common problem. Follow the instructions and setup your own DNS servers from OpenDNS: http://www.opendns.com/

Slow internet only on MacBook Pro

My internet at MacBook Pro retina late-2012 is very slow. Others computers have good connection in the same network, but in my mac the connection is terrible. I've already change de DNS, but did not have any results. The others computers reach 15Mbps, but my mac varies from 0.1 to 4 Mbps all the time, never having better than this. Any suggestions?

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 boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot 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 boot 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, reboot as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

MacBook Pro, Lion and slow internet

I upgraded to Lion yesterday to see if it resolves a persistent slow internet connectivity problem but unfortunately to no effect.
Symptoms are:
slow connectivity / download on both wireless and wired connections.
Compared to my Alienware Windows laptop, the MacBook achieves less than 10% of the downoad and upload speed in either state
Speed has been checked on many sites including speedtest.net - practically, connection is sluggish for both web and non-web internet use.
Ping to sites is identical on the Macbook Pro and my windows machine. There is no drop of ping or excessive variation.
The issue is independant of browser - Firefox, Safari, etc
I have a BT 40MB infinity connection at home and a 10MB uncontended leased line connection at work - the issue exists wired or wireless in both arenas
I can achieve download speeds of around 38 Mbps on my Alienware, wired, and 17 Mbps wireless. This compares to less than 2 Mbps on the Macbook Pro
The condition started under Snow Leopard about 4 weeks ago - unsure if it was after a routine upgrade
Following advice on these boards I have tried changing DNS to various open DNS, with no success
I have tried altering the mtu settings as directed, with no impact
The issue is therefore independant of router, internet provider ( I have access to three), wired or wireless connectivity. It also preexisted the Lion upgrade
I know there are other, similar threads on here, but my symptoms are different (no drop of ping, not just a wireless issue, multiple networks)
Any suggestions or recommendations would be welcome.
Cheers

Thanks for advise but now resolved.
Being paranoid and from a Windows background I had put an anti-virus program on - Sophos. Frankly I had forgotten about it. Turing it off resulted in a 1000% improvement in my internet speed. Who would have known?
OK I should have guessed a little earlier.
Cheers

Internet really slow on my macbook

I am using linksys WRT54G for my macbook and two imacs. The internet is so much slower on my macbook than on the imacs. I can't use the CD for setup because that is only for windows and i am using a mac. How is it possible that internet speed is so much slower on one computer and not on the other two, but im using the same router? Is there something wrong with the configuration on my macbook? Someone told me to type in the router on my web browser and change the setting to allow only G-access, but that didnt affect the speed. I dont know what to do

Sounds like a corrupted cache file, see the OnyX routine here.

Slow internet speeds on Macbook - don't want to clear cache

Hello,
Whoever can help me will go a long way with relations with my boss.
He is the only one in the office on a Macbook, and experiences slow internet spees when no-one else does. One thing to note is that he uses Sugar CRM web-based program constantly.
Clearing the cache will speed things up initially, but shortly after it slows right down again so that is not a solution that is helpful.
Looking forward to some creative responses.
Joe

Try a different DNS server .. OpenDNS
Open System Preferences / Preferences then select the Network tab. Click the Advanced tab then click the DNS tab.
Click +
Enter these addresses exactly as you see them here.
208.67.222.222
Click +
208.67.220.220
Then click OK.
Quit then relaunch Safari to test.
Safari 5.0.1 or later: Slow or partial webpage loading, or webpage cannot be found

Slow Internet connection sharing on Macbook Pro

Hi all,
I am experiencing really slow internet connection sharing via the airport from a second machine directly. I can access the internet or web pages with excellent reliability however the download/upload speed is 20KB/s at best. If I use the Macbook Pro itself I can get up to 250KB/sec. I read that this seems to be common problem with Snow Leopard. Can someone shed some light on this?
Thanks

"... I read that this seems to be common problem with Snow Leopard..."
Can you shed some light on where you read this?
