Internet on Macbook Slow, Network Speed is Fast

I have a current generation Macbook Pro. Using a comcast motorola router I am getting a wifi speeds of only 1-1.5 mbps. ON THE SAME WIFI CONNECTION my phone is getting speeds around 25-30 mbps. My phone is what my internet speed should be around (what I pay for), does anyone have any idea why the macbook speed is so slow. I am using chrome for my browser.
Thanks

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

Slow Network Speed with MacPro

I just received 4 MacPro's with the dual quad processors. I have configured 3 for our workplace and have moved them into production. We are experiencing very slow network speeds, a test file on our server of 100mb takes 2 minutes 20 seconds to copy to the desktop. I have manually set the ethernet port to 100baseT with full duplo. The old machine is running the same OS 10.4.10, and only takes 12 seconds to copy the file. I should mention that we use DAVE to connect to our servers, both machines are running the same version of DAVE, and using a third machine I connected to both drops and the file copied in 12 sec, showing that the network is physically OK. The only difference between the two machines is that one is the intel version? Can anyone offer any thing to try?
Thanks

I am 99% sure someone else had 'slow transfer' in another thread.
Sometimes a router needs firmware update to be compatible, or upgrade the cables to cat6e, or look for a new router or switch which helped my own setup. Just look for one that says that it is "Vista compatible" actually.

Slow network speed during peak times

I have begun experiencing very slow network speeds in the evening. My Mifi and other devices go from routinely getting 10 MBS down to 1 MBS in the evening. Is there any way to address this?

Rickrdn1,
Thank you for all of the detailed information. The coverage in the area looks great. All of your devices seem to drop in speeds at the same time? How is voice and text working during these times? The coverage in the area looks great, but can still be affected by congestion at peak times of usage. We may want to investigate your area further with a remedy ticket.

Very slow network speed

Since I changed from Mac OS 9.2.2 to Mac OS X 10.3.9 on my dual 450 Power Mac i am having always the same problem. after some new starts my network speed becommes very slow. internet, printer connection and also when using personal file sharing. Folder of 22MB takes about 1 hour insted of 3 seconds to send from one mac to the other. I was trying on both HD´s and with only security update from CD before using Internet. I also have to repair volume permissions.tried reset of PRAM. tried it with both HD´s separately installed, sometimes it helped for short time. but unfortunately I always get the problem also when I am not using intenet connection after installing 10.3.9 on a completely empty HD (also tried to formate mith zeros). On my other mac´s: G3 (400MHz), G4 (500MHz) PowerBook and Power Mac G4 450(single)
the system is working without any problem. same settings! Only the Power Mac G4 dual 450 I am having this problem. Software like Photoshop, X-Press and also Maxxon 4D are running fast and without problems. Please help me!!!

Slow Networking Speed

Hey,
I am getting some problem with the Internet on my virtual machine. I tested the speed with speedtest-cli tool, its showing me
Download: 26.03 Mbit/s
Upload: 13.28 Mbit/s
but the actual speed i am getting is :
100 - 200 kbps as downloading
and upload speed is also very slow.
how can i get the fast internet speed???
kindly resolve this issue.
Thanks in advance.

Hello Hemant Thakur,
1. What is the size of the Virtual machine that you have deployed on Azure?
There could be several reasons that the VM has a network performance issues. To check if there are any issues on the platform end, I suggest that you try the steps below:
I suggest that you restart your Virtual Machine to see if it makes the difference. You can do this by logging into your Virtual Machine or from the Azure Management portal.
If this does not work, I suggest that you resize your Virtual Machine. You can refer to the link below that will give you information on how to accomplish this:
https://msdn.microsoft.com/en-us/library/dn168976(v=nav.70).aspx
If these steps do not work, we might have to further invertigate this issue. I suggest that you create a Support ticket with us. You can follow the link below to create a Support ticket:

E1200 V2 slow donwload speed wireless - fast wired

I tried internet speed tested with 3 different online test it's always 0.20mbps on download and 3.8mbps on upload 2 different laptop (mine is MSI GTX640 and on a macbook)
I have tried many things already:
a) I tried many different channel even more the the usual 1-6-9-11 (i actually did try 1-2-3-4-5-6-9-11 they all go slow)
b) my security was WPA2/WPA i tryed WPA2 personal - nothing changed
c) I disabled IPV6 both on the router page and on my computer network option - nothing changed
d) in the router paged i unchecked UPNP in administrator - nothing changed
e) on advanced wireless option (not easy to reach i had to write it myself) i put 50-1-2306-2307 (on IPV4) nothing changed
f) I did put MTU to 1400 and then to 1300 - nothing changed
g) since my network card is Wireless-N (intel wifilink 5100) i changed the Network mode from "MIXED" to specific wireless-N
h) it cant be my antivirus because the macbook doenst have antivirus and go the exact same speed
i) SSID is enable and guest access is disable (i tryed both enable and disable you never know)
l) i did try to disable the routrer firewall as well - nothing changed
i just bough this router 1 week ago because the previous router died on me and with the previous router i didnt have any problem ever (till it died) always going to 1.5 or 2 mbps
so before i go buy a new one and return this one i would like to know if i am missing something in my test

Let me guess: your modem has a gigabit port. Your PC has a gigabit port.
The E2500 doesn't, probably causing a slowdown because your ISP doesn't provide you with an absolute steady 70 Mbit/s line but allows traffic bursts which average out to a 70 Mbit/s over longer time. Exaggerated example: if your ISP sends you 140 MBit/s for 0.5s and then 0 Mbit/s for another 0.5s your computer sees 70 Mbit/s. Your E2500 would only get 45 Mbit/s because it can only handle approx. 91 Mbit/s due to the ethernet port.
Wireless performance is always less than wired performance. That's because wireless connections are much more prone to interference and thus have much higher error rates. As a rule of thumb you can expect about 1/2 the wired performance.
See also smallnetbuilder for wireless performance tests: http://www.smallnetbuilder.com/wireless/wireless-reviews/31578-cisco-linksys-e2500-advanced-dual-ban...
Uploads are less prone to this problem because you don't hit the maximum rates possible, thus you have less errors. Due to the lower rates buffers can better compensate loss in transmissions. And the error-prone link is closer to the sender allow quicker retransmissions if detected on that link...
In other words: I would say what you see is pretty normal...

Slow network speed

I'm looking for advice on speeding up my network. I have a Time Capsule 3TB model a1409. Connected to Time Capsule are an iMac (via ethernet) and Mac Mini (via wireless). Also connected directly to the Time Capsule are two external drives: LaCie Porshe (Aperture file) and WD My Book. Streaming movies off the WD to either computer experiences delays. Additionally, Aperture navigation bogs down when pulling from the LaCie. Any recommendations to improve the streaming from these external drives.

Swap roles..
Use the 3TB internal drive for your files and use an external drive for TM backups.. the Internal drive is many times faster than the USB connected external.
USB is slow.. USB connected to the TC is half that again.. you cannot speed it up.. the very nature of the drive - usb interface is restricted.
Much better would be to use a FW800 or Thunderbolt (or USB 3 if your Macs are new type) plugged directly into the iMac / Mini. Thunderbolt is of course the fastest by long way.. same as the internal drive.. but super expensive still. USB3 is cheap and much faster than FW800.. although FW800 is reasonable. (Not the WD version of it) and USB2 is still the worst.
Share the drive with the network and that will be a great way to use files.. much better than USB on a TC.

Slow network speed after connecting to routers and switch

Hello
The following is my test setup I have running at my house for some practice and leaning
Some reason the PC1 which is a laptop is getting very horrid internet / download speeds, and I am trying to narrow down why.
Example, on my main desktop that is connected right to the Arris Cable modem / router I get around 34Mbps down. But the laptop that is connected in the topology above, is getting 0.06 Mbps down
I am not sure if there are settings that need to be checked on the routers or what could cause this, I am figuring the traffic is bogging at some place.
Thanks

Update on some things I have tried
As I am not sure the cause, I have been reading and trying different things, last thing was to set the interfaces to Duplex Full
I did this on both the Ethernet ports on the routers, and both of the Fast Ethernet ports being used on the switch, but has not changed the speed that PC1 is getting.
Also turned on CEF on both routers

Airdisk - SLOW read speed, but FAST write speed with Leopard 10.5.1?

I've been complaining for a while about my random problems with reading files from airdisk. My solution has always been to relaunch finder and re-mount the airdisk when it slows down.
I just noticed the speed cut down to and when looking at the activity monitor, it's fluctuating up and down and never seems to go past 1.5 to 2 MB/s.
HOWEVER, what I did just notice is that my write speed is consistently 3-4 MB/s with no fluctuation at all. Interference is not an issue, as I'm on N-only mode and in 5GHZ.
Is there anything I can do aside from waiting until 10.5.2? This does this issue in every AEBSn firmware. Thanks.

I experience the same problem (slow read: 2,8 MB/s, fast write: 6,3 MB/s) with my airdisk over a LAN-connection with 10.5.2. I atteched the USB-drive directly to my iMac and then it's the other way around: fast write, slow read (although considerably higher and normal throughtputs so drive is OK).
Anyone having some suggestions? The airdisk is formatted as HFS+ (GUID) with journalling on, Airport firmware 7.3.1 and the most recent updates installed.

Slow network speed on gigabit network

Hey,
lately I tried syncing files between my desktop pc (running Arch Linux) und my laptop (running OpenSuse 12.3) connected on a gigabit network.
Rsync was incredibly slow, so I tried measuring network performance using iperf and noticed a significantly lower speed when copying from OpenSuse to Arch, rather than the other way around.

My first idea was that possibly the network switch between them may be responsible,
so I connected the two machines directly, but that doesn't change the observed behaviour.
Any ideas how that can be possible? (840 vs 67 Mbit/s) is a tremendous difference, obviously.
Althrough I'm not even sure which machine is configured incorrectly.

After fiddling around with the cabling and different configurations, I can confirm the problem actually lies with OpenSuse.
If I use iperf from a Live CD (grml) on the Laptop, both directions give full performance.
On the other hand, if I boot grml on the Desktop (replacing Arch) and the Laptop continues running OpenSuse, the problem remains.
What is even weirder is the fact that OpenSuse also manages to give full performance, if I have the cables connected before booting the system.
As soon as the system is running and I disconnect the connection for any time, the problem occurs again.
I suspect some form of duplex mismatch (http://en.wikipedia.org/wiki/Duplex_mismatch).
However, using ethtool, both systems agree that Auto-negotiation is on, the connection is full duplex and the speed should be 1000Mb/s (1000baseT/Full).
I guess I will simply ditch OpenSuse and install another Linux distribution on the Laptop.
Although I would like to understand the actual cause of the problem.

Slow Network Speed with Dell T5400 / BCM95754?

Hi,
I'm attempting to install ArchLinux on a Dell T5400 workstation.
The network card on this is a Broadcom BCM95754, I believe:
...eth0: Tigon3 [partno(BCM95754) rev b002] (PCI Express) MAC Address...
I've booted the installer, and when it gets to retrieving the package lists, it seems to time out and fail.
When I do pings from the VT, it seems to wait 2-3 seconds before printing each line.
When I try to use "links", it takes around 15 seconds to bring up www.google.com.
I check ifconfig, and it has zero for dropped packets.
My router is a Routerstation Pro, running OpenWRT. It seems to work fine for other computers via Ethernet or Wifi.
Are there any other diagnostics or tests I can run on this system to see what's going on? It would be really nice to get Arch running on it .
Or any ideas what might be causing this?
Cheers,
Victor

heya,
Hmm, I checked my router logs - it's running OpenWRT 12.09-beta2, and I've set the logging level to Debug.
There doesn't seem to be much relevant in the logs (at least that I can see) :

Using's Google's DNS, everything seems to be fine.
Then I tested it with my OpenWRT router set as the DNS server (192.168.3.1):

It does the first part quite quickly - then it gets to the "Trying "www.google.com"" line - then hangs there for a while, before printing the two "connection timed out" lines.
Does the above help at all?
I also noticed when I run host without debug output against Google's DNS server, it mentions the last address is a IPv6 address:
www.google.com has IPv6 address 2404:6800:4006:802::1012
Is that a red herring, or might IPv6 have anything to do with it?
I've also pasted the contents of /etc/config/dhcp - which is the configuration file for dnsmaq on OpenWRT, and controls both DHCP and DNS:

What do you think the next steps are? I'm happy to run a tcpdump, if you think that would help? Or any other ways to get more data on what's happening?

Slow transfer speeds between two macs

The general setup: an iMac Intel 20" and an iBook G4 1,2GHz connected via an Airport Express (newest edition), both computers running 10.4.7.
When trying to transfer files via AFP between the two on my local network, I get "tremendous" speeds of about 0.5-1 MB/sec. Why is this so incredibly slow? Is it because of encryption or something similar? I can download off the internet with greater speed than that!

i have exactly the same problem , using a macbook black g1 . slow network speeds and flakey internet . these were ok when I first got the machine . but are now slow as . using the network view of menumeters I see that if i try and shift files from my mac mini they are incredibly slow with menumeters show 0.0kb/s for seconds at a time .
to trouble shoot this problem I used another friends macbook configured with exactly the same settings on this network and the transfer speeds were as they should be which was about 1.5-2.5 megs/sec .
so i figure there is some preference corrupted but which one ?
I have experienced several crashes recently . because of the overheating bug I have the fix applied to my machine and the firmware update . Maybe the network preference got corrupted at that point .
any tips as to which preference to delete would be appreciated .

Very slow network directory listing - but fast data transfer speed once listed?

Hello,
I have really tried to sort this myself before opening up to the community, however I have run out of ideas, and hope someone can offer the magic solution I have missed.
I am currently using the 3.4ghz i7 iMac on a 1GB LAN, running OSX10.7.2 - connecting to a Windows Server 2008 (Running Release 2) over ethernet.
If i go to a network directory that i haven't recently accessed it can take up to 60 seconds to show the contents of that directory. Once i have accessed that folder, if i come out of it and go back in it will be instant again - but the first time it lists the directory it looks like i have opened an empty folder - which after anything from 10seconds to 1 minute will suddenly show the files that are there.
Internet connectivity is fast through the network, and file transfers across the LAN are fast. (showing as approx 300mb per second) I can play and edit HD content across the network with no slowdown so I am confident that this issue is not related to the network speed itself, and is more to do with a setting on this mac.
Symptoms are very similar to this post: https://discussions.apple.com/message/12245148?messageID=12245148&amp%3b#1224514 8 - however i understand that in OSX Lion - SMB was removed - so i cannot find this file to edit.
I have tried bypassing additional hubs in the network by wiring direct cables to the switch that is connected to the file server, this made no difference.
I have also tried disconnecting the ethernet cable, and running over wifi. This fixes the listing problem, but when editing HD content over a network drive, this connection is not fast enough to carry the data without interruption (some projects are linked to up to 900gb of hd video content!)
Using ethernet, I have tried DHCP, DHCP with manual address, and manual mode. All reproduce this problem. i have tried using the windows workgroup, and tried without it.
I have also followed this suggestion: https://discussions.apple.com/thread/2134936?threadID=2134936&tstart=45 and used OpenDNS. this did not fix the issue.
For argument sake, I have also just tested a Macbook Pro running Snow Leopard to see if it was OS related. This reproduces the exact same problem, near instant directory listing on the wifi, a long and arduous wait on ethernet.
I cannot work out why directory listing is instant over wifi, but not over ethernet on 2 different macs, running 2 different versions of OSX. I also do not understand why if the network is having trouble listing the directories - the data transfer speed is 300mbps when i copy files across the wired network from the file server to the mac.
Does anyone have any other ideas as to what could be the problem here? We are about to start work on a very large project, where the content we are editing is spread out across around 200 different network folders (different shoots captured over the past 2 years). We really don't have the time to wait 60 seconds each time we need to access one of those directories to look for a file, and I am very close to pulling all my hair out!
I really look forward to hearing from anyone who can offer any insight.

If you are suspecting that the Windows update had something to do with your LAN going slow, then try the following:
1. Look for updates for your clients LAN NIC driver; or
2. Un-install the updates.

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

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:

and here:

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:

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:
