Download speed slow on Mac Pro but fast on MacBook Pro

I have an early 2008 8-core Mac pro, 6 GB RAM, running 10.6.8. I'm connected via ethernet to the HITRON CGN3 modem/WiFi router from Rogers. I'm only getting about 20Mbps download, and 10 Mbps upload. However, when I connect my 13" 2011 MacBook Pro (8 GB RAM) to the modem, also running 10.6.8 and using ethernet into the same port, I get about 80Mbps download and 10 Mbps upload. Even using WiFi, my MacBook Pro is able to get about 80Mbps download.
My network settings are the same in both my Mac Pro and my MacBook Pro. I should be getting around 60-80Mbps download on my internet plan, but my Mac Pro is underperforming.
Anyone know the solution, or have experienced a similar issue?
Thanks in advance.

Grant, you sir are a mega genius.
The culprit was the ethernet cable. I plugged the cable I was using for the Mac Pro into my MacBook and experienced a drop in download speed. Upon inspection, the cable had 6 wires. Who knew? This cable worked with my previous modem, and my speeds were pretty good. I just upgraded my internet package, and got this new modem, so I guess the cable is no longer incompatible.
Now that I've replaced the ethernet cable to my Mac Pro, my download speeds are smokin'.
Thanks, man, you saved the day!

I mostly work on Mac desktop, but use a Macbook Pro on trips. Due to limited HD space on the latter, I want to create a library of part of the images on the Mac, to be used on the Macbook. I do not however want to remove these images from the Mac library.

Choose one or more Projects, and then use Export as New Library (from File). The resulting export will be a fully functioning Aperture Library to either transfer and open on the Macbook Pro, or to Import into a library you already have on the MBP.

Download Speeds slow on Mac, not on PC, Parallels or Bootcamp?

I recently switch from DSL to Cable because they offered higher speeds. I don't know if this affected DSL before because they only offered up to 2.5Mbps, the cable internet I'm on now is a 7Mbps/1Mbps line.
For the life of me, I cannot figure what is happening with my configurations. I have 2 PCs at home, a intel imac, and a macbook. When I run speedtests on dslreports or when I download large files from microsoft/apple, I get great speeds on my PCs. Around 880KB/s down. However, when I try to do the exact same thing on OSX, I get speeds around 260KB/s and it seems to be capped there.
The strange thing is that when I run parallels or boot camp, and try the exact downloads or speedtests I get the correct 7Mbps that I'm supposed to get. Am I doing something wrong with my configurations on OSX? It doesn't make sense that I can download in a window on OSX running paralles and get the fast speeds but thru OSX I cannot?
Both OS's are running Firefox. I've tried Safari and Camino on OSX and get the same results. I'm guessing its not a hardware problem because winxp on parallels and bootcamp get great speeds. This affects both my iMac and macbook. Any help would be appreciated

I have a 24megabit ADSL+2 connection and I had the same trouble as you.
When using Ubuntu or windows xp in parallels I had maximum uploads and downloads. But this was not the case in OSX.
My ftp uploads in osx were like 45k yet in ubuntu the were 120k to the same server.
I tried all sorts of methods to fix the problem.
But it turned out my problem was the router, I had a thompson/alcatel router a recent model.
I tried a cheap netgear adsl2+ router and bingo all my problems went away. I now have the same speeds in OSX and XP and Ubuntu.

Parallels Desktop v3.0 corrupts downloads on Mac Pro but not on MacBook Pro

Parallels Desktop for Mac version 3.0 is corrupting downloads and updates on my Mac Pro, but not on my MacBook Pro. Symptoms include the message "The digital signature for this package is incorrect. The package may have been tampered with or corrupted since being signed by “Apple” when downloading a software update. Downloading a dmg software package fails at the end of the download with a "Verification failed" message. Trying to mount the package manually fails with codec overrun error. These are symptoms of a corrupted download.
The problem disappears when I uninstall Parallels. It reappears if I reinstall Parallels. My Mac Pro and MacBook Pro are nearly identical in installed software. I have reviewed the problem with AppleCare in excruciating detail (an hour yesterday and another hour today with an AppleCare Specialist). It is a new issue to them. We have send a support request email to Parallels.com.
This has been a difficult problem to troubleshoot. I had tried every suggestion that I could find on the forum under "Digital Signature is incorrect", "Verification failed", "codec overrun", etc., without success. I won't go into the painful details of the troubleshooting process, unless encouraged. But I will update the forum when I know more. Meanwhile, if you have any ideas please pass them on.

The problem has been solved by replacing the Linksys WRT54G Wireless-G Router with an Apple AirPort Extreme 802.11n Wireless Base Station. After completing the installation I was able to successfully download my test .dmg files on the both the Mac Pro and the MacBook Pro with Parallels 3.0 installed.
Before I had made this change I had worked with a Parallels tech support expert. (By the way, they were very responsive.) We had tried a number of things without success, including disconnecting and restarting the cable modem and router.
I don't know why this change in routers worked. It couldn't be related the WEP encryption on the Linksys versus the WPA2 security on the Airport Extreme because the problem was not with the wireless connection to the MacBook Pro. The problem was with the Mac Pro, which was connected via an ethernet cable, in both cases.
I am now happy, but confused.

10.6.5 allows rename of Public folder on Mac Mini but not on MacBook Pro

I have 10.6.5 running on a brand new Mac Mini and it lets me rename my Public folder so I can recognize it easily on my home network. My one year old MacBook Pro has this renaming option grayed out and I can't find how to enable it. I've looked at the sharing preferences and other places and I've searched this support forum.
Any ideas of what I might be forgetting to check, or set, or disable, or something?

Thanks for the tip. I marked my question solved, but I'm not really sure why one computer lets me rename and the other doesn't. I'll bet you're right and I shouldn't be renaming that stuff. I used Time Machine to go back to before I did that.
I'm now connecting to both machines as a registered user and I can ignore the Public folders anyway.
One thing still puzzles: the MacBook connects to the Mini almost instantly, but the Mini takes maybe a minute or more to connect to the MacBook. I thought about it waking the disk from sleep, but I've tried this right after making the MacBook do something to make sure it's spinning the disk. Maybe I'll play with it some more and search for answers or post another question later.

Checked download speed on 'speakeasy', over 5mbs, but site open too slow

certain web sites like WGT.com open very slow, even when my download speed is at 5mb/s or faster. Why is this?

Paul,
can you carry out a speed test and post the result please?

Airport download speed SLOW!

I am having what I have found to be a common issue (from searching Mac forums)with Airport speeds on my Mac Pro. I am getting very slow download speeds with on my Airport Express network, however my upload speed is normal. I have 2 Mac laptops on the network, both receiving 2.5 to 2.8 mbps download speeds while the Mac Pro, 3 feet from the Airport, downloads between 300 and 1000 kbps. All computers are configured the same, and everything is working fine on the network, including the 2 laptops and an Xbox 360. Only the Mac Pro is experiencing problems.
Upon first hooking up the computer, it worked fine, but later in the day developed a problem with connecting to the network. A clean re-install fixed the problem, however, after a week or so, I am having the speed issue. While I was once able to stream music and video and use wireless printing from the Mac Pro, it is now too slow.
Furthermore, when selecting the airport icon from the menu bar, the computer hangs for a couple of seconds before opening the menu. Is there a solution to this problem? I have been unable to find a solution on the internet, yet I have read of several similar and identical problems with Intel-Macs.

After a lengthy walk-through with an Apple Tech, we were able to fix the problem by power-cycling the Airport and Modem, erasing my network (in the Airport settings in Network Preferences) on the Mac Pro and re-adding it to the Preferred Networks, removing all cables from the Mac Pro, waiting 20 seconds, reattaching cables and then zapping the PRAM (apple, option, P, R) after the chime on start-up. Seems to be working fine now, hope it lasts!

USB speed is limited to the speed of all the connected devices on the same bus. The bus is the portion of the computer's data traffic cop that connects several USB devices at once. Go to Apple menu -> About This Mac -> More Info to determine if there are any slower items connected to the same bus. Some USB ports may connect to a different bus under the USB section. If you want to see which bus a device has moved to after physically moving it, select Refresh from the View menu. Additionally some USB non-Apple devices may trip up if you put your machine to sleep either but closing the lid, or manually from the Apple menu, or automatically through the timer in the Energy Saver System Preferences. Some of these connection devices have latency issues. This means, they need a place to store their downloads before they come onto your computer. It may be their driver on the PC has settings to store something on the machine directly. Make sure your Mac isn't too full*:

your router usually directs name resolution requests to bt dns servers
these convert web addresses that you type into numbers that the internet needs
bt dns servers are usually poor which could be responsible for the problems you have but the router doesnt allow you to change them
however it is possible to override them in the network settings of the pc

I updated to OS X Mavericks and now trying to run Logic Pro X on a MacBook Pro mid-2009, using an M-Audio Axiom 49 and an M-Audio Fast Track Pro... Logic keeps telling me that Mac OS X MIDI Services are not available... How do I solve this problem?

I just checked to see if the update to OS X Yosemite 10.10.1 solved any of the issues outlined in my previous post, and to my dismay, nothing has changed -- all of the previous problems persist.
My iMac (8) -- it's renamed itself eight times since the recent troubleshoot with the Apple tech rep -- shows up as a shared device in Finder on my MacBook Pro, but when I click on it, I cannot establish a connection using "Connect As". So I've attempted to connect using the menu "Go/Connect to Server...", using both (alternately) the iMac's name and IP address, to no avail. I get a message which reads: "There was a problem connecting to the server 'Peter's iMac (8)'. This server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
Here's what I know:
The server -- Peter's iMac (8) does exist;
The server -- Peter's iMac (8) is available at this time;
The server name -- Peter's iMac (8) -- is correct, as specified in the system sharing preferences;
The server IP address is correct, as specified in the system sharing preferences;
The network connection is active when I attempt to connect.
I'm convinced the problems stem directly from the OS X Yosemite update. None of this was ever remotely an issue in the previous OS X's -- any of them. This is maddening! What can be done? Apple?? Anyone???

I purchased and downloaded an episode of a television show onto my MacBook pro, as I have done before, but this time it only plays without audio. What gives?

Okay, so the download is possibly corrupt. Did you try downloading again?
Also, you'll likely get more appropriate responses posting to the iTunes for MAC forum instead of the iTunes for Windows forum where this currently is.

I'm trying to download java on my Mac machine but the software update doesn't show me anything. Please advise what I should do to get the application.

If you can run it under chrome, you have java installed.
There was some malware that exploited an older version of Java (not javascript) running in a Browser. Since few people use it Apple turned off Java by default in the Safari Browser.
If you need it for something, just turn it back on in Safari preferences (inside Safari). After a few months of non-use, you may find it has turned itself off again.

Thanks,

Try enabling the Personal Hotspot on the iPhone and connecting the Mac to the Internet thru it. If Facebook works ok then, that would mean the ISP is either blocking or having connection problems whereas the phone carrier is not.
Be mindful that carrier data charges can be outrageous so use this as a test first.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Downloads Speeds Slow

I recently had my DSL modem/router fail. My service is through Qwest, and got a new Qwest sanctioned modem/router (Actiontec PK5000). I am using a wired ethernet connection to the modem/router. When I do speed tests it says I have a download speed of 1,200KB/Sec, but when I download a file it shows the download rate at <150KB/Sec. I contacted Qwest and they say it isn't anything on their end and that it is being limited by my internal ethernet adapter rate. I have no clue whether this is true or not, and if it is I don't know how to change it. Can anyone help me?

It's very rare to get the same speed during a speedtest and while downloading an actual file. It often has to do with the speed of the server you are downloading from. With a 1.2mb/s connection, 150kb/s isn't a bad download speed.
