Internet connection slow only on Mac Pro

For what its worth, I also had a very slow connection through my cable modem after switching from a G4 to a Macpro. Web pages hung up for 5 - 10 seconds before donloading. Download speeds were great on the G4, very slow after switching to the MacPro. If I went back and connected through the G4 everything was fine. A simple solution that worked for me... Turn off the computer. I unplugged the power from the cable modem, unplugged the coax cable from the back of the modem and let it sit for at least a few minutes to reset. Connected the cable, connected the power supply, started the MacPro - everything was great. I read that sometimes the cable modem does not realize is on a new piece of hardware and it might need to be reset. That worked for me. It have better download speed than before. Hope this helps someone.

of goodwill

Update: Apple Engineers have analysed the data I sent them and have found out that my Ethernet hardware is failing (turning itself on/off continuously which also causes the kernel (network part) to be affected negatively). This will affect networking overall, so Airport will also be affected. I'm switching the hardware next week and will get back to you all if it solves the issue or not.

I hope this isn't an "across the board" type of ethernet hardware bug, and just individual cases like yourself... Airport Express though does seem to have a high problem reports.

We get so many storms, and I even keep an older (DSL) modem as a just in case the surge protectorS don't do a good enough job. Too many cases of modems getting fried by lightning and surges.

I'm always glad to hear how an issue is ultimately resolved.

First... sorry for my english (i´ve used BabelFish :D). My Mac Pro is OK NOW!! 😀

then it seems to be that this error that is taking place in many MacPro, by which the level of signal of the Airport is very low.

I proved with 2 routers, a LinkSys WAG54G v2 and a Comtrend de Timofónica, because it is that I decided that was problem of the MacPro, so I requested a change, came the new MacPro to me, but nothing, the signal continued being equal of bad.

I decided to remain hoping it to that they remove some solution:) Then it is that today the LinkSys is had broken, so I have put the Comtrend... I have proven configurations and in the end... (like always:rolleyes: ) to worked!

It is that in an option that has by name [ b]54g Mode[/b ] had position [ b]54g AUTO[/b ] I have been it changing until I have arrived at [ b]802.11b Only[/b ] tachaaaaaannn! signal to top! and very happy I! 😀 so they already know, if they have some problem with the reception to Internet prove to put the Router Wifi in Way in 802.11b Only! jejeje!

Regards!! 🙂

Yordan,

I am very glad things finally work better. 🙂

It is that in an option that has by name 54g Mode had position 54g AUTO I have been it changing until I have arrived at 802.11b Only tachaaaaaannn! signal to top! and very happy I! 😀

so they already know, if they have some problem with the reception to Internet provider, to put the Router Wifi in Way in 802.11b Only! jejeje!

Well this seems like a really lame solution... having to force my 802.11g to reduce to speeds of 802.11b just for the sake of full signal strength. This really needs to get sorted out, hardware or software wise because paying a large sum of money for a crippled AirPort card does not make too much sense in my book.

Just my two cents here...

hello everyone-

I just recently started experiencing this problem. on my end, I've had the 4-5 second beach ball when trying to access the airport menu button, and abysmally slow internet speeds. For me, it appears to be related to sleep, as after waking up is when it exhibits the most crawling speeds. After a restart, everything works well, and my upload and download speeds are back to what they should be. It seems like an answer that's too easy to be true, but it is, at least in my case. I eagerly await a true fix, as the rest of you surely do, since I don't see restarting every time my computer goes to sleep as a true FIX for the problem. might as well just shut down every time I'm done with it.

Then the problem can be the same one to make work the Parallels with VT-x. simulation. Was necessary to let to seconds the MacPro in sleep mode to be able to activate it...

Soon I will prove to swith-on the MacPro and to connect itself by Airport when router to 54g, I will put it in sleep and I will try the same. To see if it works to 54g 🙂

Thanks.

Hi Yordan,


I do not know what you are so excited about. 1. The "solution" is not new. 2. Going back to 802.11b does not improve the speed at all.

It may look better on your desktop (all bars black) but it does not solve the problem at all.

Apple: Where are you? You begin to suck, you know, leaving us completely alone with problems you are responsible for!

Regards,

Armin

I was happy until soon I read that 802.11b was much more slow 🙂

The truth is that I am very displeased-disgusted with Apple. For expample, my MacBookPro warms up much, when I put it to the minimum brightness blinks the screen, gives cramp when I touch it barefoot, and has that annoying noise, to part which the screen is a little doubled. A pain of portable to price of gold.

The MacPro is an enormous machine but Apple cannot allow these failures. As soon as posible I will sell the MBP because I have taken him defrauded and hurt 😟

Apple, I´m NOT a beta tester.

Regards.

Have been suffering slow download speeds over airport on my MacPro since it arrived. 10Mbit cable modem is fed into an airport extreme base station and results shown from speedtest.net in safari and firefox (makes no difference):

Mac Pro 3Ghz via airport extreme: dl 3965 kb/s ul 476 kb/s
Powerbook G4 12in airport extreme dl 9529 kb/s ul 478 kb/s
iMac core duo ethrnet to base station: dl 9679 kb/s ul 478 kb/s

Mac Pro has never risen above 4000 kb/s and a Powerbook sitting next to it has over double the throughput almost matching the directly connected iMac. Something very wrong here....

That is really interesting.

I think the two faster machines are hitting the upper limit of your ISP connection.
It would be interesting to measure the speed, after taking the internet connection out of the loop.
So moving a large file across the network would show the effect even more.
Try moving a file from the Pro to the iMac....and compare with a file from the Powerbook to the iMac

Test file is a 24.8MB pdf
Mac Pro and Powerbook directly upstairs from base station both have 3 out of 4 bars airport signal strength in menu bar. iMac is attached to base station via ethernet.

MacPro - iMac : 56 seconds
MacPro - Powerbook 84 seconds
Powerbook - MacPro: 91 seconds
Powerbook - iMac: 31 seconds
iMac - MacPro: 55 seconds
iMac - Powerbook: 18 seconds

(As a reference I can place the Powerbook downstairs next to iMac and base station and transfer the same file to and from Powerbook and iMac in 6 and 9 seconds. MacPro to Powerbook improves slightly to 75 seconds...)

Sitting at the MacPro the Airport signal strength is the same for both the Mac Pro and Powerbook when placed side by side - but MacPro has a much much worse transfer rate. My older G5 tower had a markedly better throughput in the same location.
