Wireless Internet Problem With Mac Pro's

Hey, I have an identical story - very poor wi-fi performance from a succession of Mac Pros - have tried everything with no joy. Would not recommend to others - stick to ethernet if you can...

Hey Poplin,

I just want to add that i've got exactly the same problem, I live together with several persons who all connect with no problem to our internet and have high speed.

With my Mac Pro OSX 10.6 i connect but without any reason it randomly decides to stop the connection while i still have my airport bar full. I tend to disconnect the airport and most of the time after it says server temporarily unavailable (while other people are connected without downloading something heavy for example). Anyway generally my internet is way slower then others with the same internet.

Nice to know i'm not the only one but let's hope someone can tell us about solutions..

Having same problem. Need a fix quick on this one.

Same EXACT problem here ever since I upgraded to snow leopard 10.6 on my new 8 core 2009 MacPro. I have tried several of the suggested fixes such a changing security, removing and re-adding the airport interface, dhcp/static ip, removing some of the preference files, etc. I really find it hard to believe that Apple has not addressed this yet. I have multiple other wireless devices on my network including a first generation macbook still running 10.5.x and it is fine. My itouch, xbox, pc's, etc. are also having no issues.

I have a $3k+ computer that has been hobbled by a slow and flaky internet connection for a couple months. Sad...

Ditto here. I'm working with my MacBook Pro right next to it. The router is in the room above me. I've got three other computers accessing the internet just fine (one of them is a 7-8 year old Powerbook). It's definitely a problem when trying to update software or send sound files to someone.

Ugh.

My Macbook Pro and Mac Pro are sitting less than a foot away from each other and both are connected to the same wireless network. Yet, it's only my Mac Pro that has poor wireless connectivity since upgrading to Snow Leopard. It's terribly slow, and makes online gaming a nightmare and downloading media even worse. I've tried EVERYTHING aside from dragging the 70 lbs tower down to an Apple store.

Try using a different modem and/or switch, or see if there is newer firmware for the one you have.

Wouldn't this not matter? As previously stated, my Macbook Pro is sitting right next to my Mac Pro and they're connected to the same wireless network but only my Mac Pro lags horribly on the network. Neither of my roommates have trouble with the wireless signal/connection on their computers either. To me, that seems like evidence that its the computer.

Just got my new Quad Core with WiFi delivered today and the wireless is complete and total crap. The last Pro Mac I owned, a Single 1.8 G5 never had these issues with it's EXTERNAL antenna jack. Otherwise it looks like it's going to be a great machine.

Today I tried the following Apple devices at the EXACT same spot the Mac Pro sits at with almost no wireless.
Apple TV- fine, iPod Touch- fine, MacBook (Aluminum- not Pro)- fine, Mac mini (early 2009)- fine, old White Plastic Core Duo iMac 20"- fine, White MacBook Core 2 Duo- fine. I think we can say the problem is NOT the Airport Extreme Base Station or theISP.

The thing will a) not detect the base via Wireless settings or the AirPort Utility and not even connect, will show 100% and no internet connection and no Base Station on APU, or will connect with almost no signal and will flake out after a very short time.

I have changed channels, changed the multicast rate, etc and it doesn't hurt the other units- just the Mac Pro. Apple needs to stop worrying about pretty and put the external antenna jack back on the next revision. In the meantime, what suggestions does anybody have?

I just took delivery of an 8 core with WiFi.

I dual boot with another drive that has Leopard 10.5.8 (For ProTools)

My download speeds on DSL reports show 22 Mb with Leopard 10.5.8
But the download speed with Snow Leopard 10.6.2 are 4Mb!!!

Same computer!!

My wireless barely worked when I got mine last week, I opened it up, and switched antenna wires.
Rather than 1 and 3 to the airport card, I did 2 and 3, and it started working.
Still not the greatest with Snow Leopard.
See my other post on this thread.

I have the same exact problems. I was hoping the last apple software update for airports would fix the issue but it has not. I just asked about the same issue in this forum before I saw this post.

Has anyone called apple on this? I just haven't had the time to sit on the phone and run and most likely run through things that I know won't help. I'm finding it hard to believe that Apple hasn't recognized this issue and fixed it yet with this many people in this and other forums reporting the same issue.

I finally got around to looking inside the case for the airport antenna connections. My 8-core 2009 MacPro looked nothing like the instructions for the 2007. http://meanderingpassage.com/2007/07/18/how-to-installing-an-airport-extreme-car d-in-an-intel-mac-pro/

In fact the internal airport card and connections appeared to be in a totally different place near the bottom of the motherboard (I think I had to remove the CPU tray too, forgot). I also did not see access to any connections to (1-2-3) to swap. Is this where yours was?

I called apple, they told me it was interference.....i'm not buying it. I have had this computer working great a year and a half with no problems. The only other option they gave me was to take it in to the store, saying the card may be going bad. Im going to take it in and let you know what happens.

I've got an Intel 3 GHz Quad-Core tower and a 2.8 GHz Intel Core 2 Duo 17" Laptop. The internet at my office has never been very fast, but it was reliable until I upgraded the tower to 10.5.7 and it hasn't worked reliably since. The same is almost true of my new laptop I spent $3k on. The difference is the laptop came with 10.5.7 already installed. I noticed at home my wireless connection with the laptop was terrible yet my girlfriend's old G4 laptop worked flawlessly. The new laptop will work wonderfully on some wireless routers (I suspect they are brand new,) but not on the ones I use regularly which are older and work fine with other computers. I can't even print or connect to iTunes between computers without communication errors. Never had problems with either until after the 10.5.7 upgrade.

I've since upgraded the OS again to 10.5.8, but it hasn't helped and I'm guessing since others have had the same problems with 10.6 that there is no solution yet.

When did apple come out with the new Airport Extreme Base Station with the new 802.11n standard? If the release of the new 802.11n standard and OSX 10.5.7 coincide, I would guess the problems we are experiencing are due to OS upgrades that make working with the older 802.11g standard virtually non-functional.

When I purchased the new laptop, I was a bit frustrated with the inability to connect it to my television via s-video as I had previously with my old G4 laptop. When I realized there was no configuration of proprietary monitor out cables that would enable me to connect to s-video I asked a salesman at the local Apple store why that was. His response was "Apple is all about the future, we don't support old technology." If that is in fact the case, then I would guess our problem is with Apple's philosophy not our wireless hardware.
