8x slower download speed than Windows laptop on cable
I have cable internet (in Luxembourg). The provider uses Scientific Atlanta EPC2100R2 modems. Download speed is around 1 Mbps, rather than the 8 Mbps advertised. When technicians come to investigate, the connection is 8 Mbps on their Windows laptop. They claim to have several clients on Macs, and none have the problem.
My modems also get fried very often. The provider had to replace my modem twice in four months.
The problem persisted after I replaced my iMac. It may be a software issue, though, as I migrated my old Mac to the new one.
My Mac works fine with ADSL. I haven't tried it with other cable providers.
What can I do? I tried creating new locations in Network preferences, to no avail. Always the same result.
wireless is unreliable for the speedtest as it varies depending on home conditions so only way accpeted is by cable. if that also shows a problem then you can take it from there

IPad 2 / Apple TV slower download speed than laptop?
My Apple TV (gen 2) and iPad 2 both have issues with download speeds. Netflix has pretty much become useless on my Apple TV due to the slow download speeds. I'm currently using CableOne for my internet provider and I consistently get ~ 20-25Mbps download speeds on my laptop, but only around 0.75Mbps on the iPad 2.
I use a Linksys WRT64G router and currently have it set to use wireless "G" only, QoS and WMM disabled, WPA Personal Security with AES encryption and the wireless set to channel 1. All these settings were based off other user's findings that have had the same issues and yet I'm still having problems.
Both the iPad and the router have been rebooted without improvements.
Any other suggestions?

Very slow download speeds with new laptop with windows seven- WRT160N Router
Just bought a new Laptop with windows 7 and of course wireless. Download speeds are horrible (0.2 mbs) and upload speeds are normal for me ( 8mbs) Have a wrt160N Wire less router. Older laptop and desktop work fine with normal( around (8mbs) downloads and uploads.
How do I fix this?Do you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

Very slow download speeds on windows vista using boot camp.
Ok this is my problem. When ever I try to download something from the internet on my windows side the download goes very slow. When I go on my mac side and do the same download it goes a lot faster. So then I went to speedtest.net and my download speed came back around 5000 kbps, when I go into my windows side it goes about 500-1200 kbps. How can I get my download speeds to 5000 kbps like it is on my mac side? I have been trying this for a long time and trying many solutions. Any help will be appericated!
Thanks!Start by troubleshooting networking.
Drivers for your Windows chipset.
Include more details as to router, firmware, what MAC you have even?
I would never disable firwalls or AV and security settings but you don't want to have two firewalls running.
Most people complain that Windows is faster and their OS X is slow.
Also, wired or wireless? you have not given us anything to go by. -
Slow download speed on my macbook pro compared to windows.
Hello,
When i use my macbook pro to download a file i hit very slow download speeds (50 kb/s tops), compared to fast download speeds in vista using boot camp (300 kb/s tops) and the same when i use my brothers PC.
Anyone know how i can fix this or why it might be happening?
thanksCommon strategies:
* Use ethernet instead of wireless.
* Get a better/upgraded ISP.
* Get a better/upgraded router.
* Get a newer mac. -
Very slow download speeds with ATT U-Verse
Hello,
Experiencing very slow download speeds with Macbook Pro 2011, on Lion, and ATT UVerse Max, which should allow for an avg. 11-12 MBPS speed. Instead, I get a fluctuating 60-370 kbps speed. I am not experiencing this problem on my Windows machines (Laptop running Windows 7 and Desktop on XP), it is only affecting the Macbook pro. I wonder if this issue is a known problem with ATT U-Verse and Macs, I spent hours yesterday with their support online and they couldn't help me, stating that from their side all settings were OK; the first representative from ATT re-booted the router remotely and that seemed to work for about 10 minutes, and then it went back to a crawling speed...
Any suggestions welcome!
ThanksDo you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

Sigh slow download speeds iPad
Is anyone having problems with slower download speeds on iPads and if so any suggestions to fix? Also some videos on my laptop, ex: like twitter mobile uploads I'm trying to view, are slow. Come to think of it, some youtube things slow to download on laptop, too, so not the sites' faults.. Is it Verizon's? Why is the download speed erratic to non-exisitent on certain videos with Fios?
The first thing that needs to be checked first is the FiOS connection. Go to http://measurementlab.net/measurement-lab-tools#tool1 and perform a speed test using a computer connected via Ethernet and see if the results match what you should be getting on your connection. Additionally on the iPad, visit testmy.net and perform their download speed test. If you have any additional PCs in the home that can use Wireless, perform a speed test over Wireless using the Measurement Lab address.

Very slow download speed with intermittent halts
Need some help.
I run Apple os/x latest version and have since yesterday begun to experience constant very slow download speeds.
I have rebooted the router and I have reset it. I have tested with wireless and wired into router. No real change.
The results are below and are pretty consistent no matter when or with what computer I test it with.
This is very frustrating and I would like to know if anyone has experienced this and if there is anything I can do before calling for service.
Thank you in advance.

I was experiencing slow downloading speeds
I was experiencing slow downloading speeds(13.68Mbps) so I called my ISP. The ISP tech asked me to disconnect the cable from the airport express & plug the cable directly into the iMac. When I ran the speed test again I got 40.34Mbps download speed. The tech said that was proof that the problem was with the Airport Express & not the modem. However, now I do not have WiFi. And now I am only getting an amber light on the Airport Express. Any suggestions on how to have WiFi without slowing downloading speeds? Note: Downloading speeds were good until this last week. Please help!
Hiya
Airport Express model 802.11 Version 7.6.4
Does it have two ethernet ports on it?? or just one?
You suggest that I replace the Airport Express with an Airport Extreme: I do have an Airport Extreme in another room by our TV & Blu Ray to enable Netflix movies. A Mac Store technician set up the wireless system that way in 2010. Can I use 2 Airport Extremes instead?
Yes, that is no problem. I am guessing the Extreme is linking by wireless?? Or do you have ethernet between the Extreme and Express?
I am afraid of suggesting this, but I would consider just swapping the roles.. put the extreme on the modem.. and the express on the TV and bluray player.. and it will probably work fine.
What are speeds like to the Extreme on the TV? Does netflix play properly?
If you shut down the Extreme, does the speed get better on the computer?
Are you suggesting that the modem should be bypassed and the Express should be connected to the Mac by ethernet?
Not exactly.. you should already have an ethernet from modem to the express.. can you plug another ethernet express to the Mac.. assuming your Express has two ethernet and not just one.
"Try manually setting channels and forcing bands with different name." : I do not have any idea of how to do this.
Try the simple alternatives above. We can consider this as well if those don't work.
Do you have someone you could call easily and cheaply to try and sort the problems??
Otherwise buying a new AE is actually probably just as cheap as getting a technician in to look at it. Not that new equipment wrongly setup will work any better than old equipment wrongly setup.. but you have a month of free phone support from apple when you buy it new. -
Trying to download Adobe Standard and experiencing extremely slow download speeds. My internet connect is good, and I've tried restarting. nothing seems to be working.
Out of curiosity I just downloaded Acrobat XI Standard from http://helpx.adobe.com/acrobat/kb/acrobat-downloads.html
The download completed within less than 3 minutes, and I am 10,000km away from the Adobe download servers, at the other side of the Pacific ocean. -
Slower download speeds from Arch
Hello,
I am getting slower download speeds from Arch Linux than from my other distros. I have googled and applied the following "fixes" but they don't improve the download speed.
1. I shut off ipv6:
# /etc/modprobe.conf
alias net-pf-10 off
alias ipv6 off
2. I shut off ipv6 in firefox.
3. Here's my /etc/rc.conf:
DAEMONS=(syslog-ng iptables dhcpcd network netfs portmap ntp crond alsa gpm kdm cpufreq)
lo="lo 127.0.0.1"
eth0="dhcp"
INTERFACES=(lo eth0)
4. Here's Arch compared with Zenwalk:
Arch vs Zenwalk download and upload speeds by
http://www.speakeasy.net/speedtest/
Arch 17719 kbs down 2049 kbs up
Zenwalk 21537 kbs down 2779 kbs up
5. Ping tests are equal:
Arch: 64 bytes from 64.233.167.99: icmp_seq=1 ttl=242 time=41.2 ms
Zenwalk: 64 bytes from py-in-f99.google.com (64.233.167.99): icmp_seq=34
ttl=242 time=40.5 ms
6. I also tried a different browser, and tried stopping iptables.
Can anyone help?

Thank You,
I was just about to ask about kernel modules/drivers. forcedeth is the nic driver, I think. But i have no idea how to correct something that's compiled in. I will stay with what I have for now. until I learn somemore. I like Arch Linux and plan to stay with it.

How many thousands of Apple TV users have to scream their complaints before Apple will respond to the fury over the impossibly slow download speeds of movies bought through iTunes?
As jules says, your rate (currently at least) may be slow.
If it used to be good I wonder is your ISP is slowing ('throttling') your speed after you've used so many GB of a quota each day or month - check what they think you should be getting as a download speed.
While Apple's servers do occasionally play up, it's generally the ISP being slow not Apple.
If you're using Google's DNS servers that has caused issues for some.
Recommended speeds for near instant playback:
SD 2.5Mbps
720p 6 Mbps
1080p 8 Mbps
Is your speed test from somewhere like speedtest.net?
It might be helpful to post Mbps to ensure we/you are not confusing speeds by using different units to those measured.

Hi,
I am experiencing very slow downloading speeds, when I am just normally downloading something in Safari, or downloading a torrent with upto 100 seeders.
The maximum download speed I have seen on my computer is 80kb/s, which is painfully slow for downloading the Adobe trials, when they reach about 1gb.
I have a router, connected to 2 computers, and speedtest.net has told me that my download speed is 1mb/s.
It seems like download speeds are being restricted to 80kb/s, so is there any way to 'unlock' full potential downloading speeds?
Any help much appreciated!
-Ollie
Message was edited by: Ollie AI think you're making the same mistake a lot of people make.
The maximum download speed I have seen on my computer is 80kb/s
Safari reports downloads in kiloBYTES per second, not kilobits, so that 80KB/s translates to about 640 kilobits per second.
downloading the Adobe trials, when they reach about 1gb
Really? 1 gigabit per second? I assume that's a typo.
speedtest.net has told me that my download speed is 1mb/s
therefore your downloads are progressing at about 64% of maximum. That sounds about right - you won't get maximum throughput for every download - it will vary based on server location, network load and more. -
I need to update to the latest version of Snow Leapord-currently running v10.6. Because of where we live the slow download speed for such a large file has kept me from downloading the update. What can I do short of hooking up computer elsewhere?
Do you ever visit a friend or realtive with a Mac who has faster internet? Maybe the local library has Macs on a fast line. If so, get a USB thumb drive and put this link on it from your computer:
http://support.apple.com/kb/DL1399
Then put this link on the drive:
http://support.apple.com/kb/DL1429
When you are at some place that has a Mac with a decent download speed. insert the thumb drive in that Mac and click on the first link ("DL1399") and direct the download to your thumb drive. Now do the same this with the second link.
The installer files will now be on the thumb drive and, when you get home, drag them from the thumb drive to your desktop. Install the Combo update first. -
my photoshop elements and Lightroom serial numbers won't work for my new mac. I bought these softwares via download on my windows laptop but returned that laptop because the quality was not great. I decided to buy a mac and now can't use my serial numbers to download the software.
Moving this discussion to the Downloading, Installing, Setting Up forum.
Stephylei you will want to download the Mac versions of the installation files. If you purchased the software from Adobe, and choose the download option at the time of purchase, then the download will be available under your account. You can find more details at Find a download link on Adobe.com.
