Macbook - Intensive graphic make me loose internet

[Keytachi]

I have been having the problem over a long time now, but it has come to extreme situations at the moment.
Usually when I play WoW (this was the first times this problem happened) if i make a sudden turn of the camera/teleport/anything thats graphic intensive, i loose my internet connection.
I checked the network diagnostic, and only the Ethernet and Network Settings were green, the rest was red. My fix for this was to restart the computer.
Recently anything that is graphic intensive makes the internet crash, and i reboot the computer 5-6 times a day.

Here's the log from when the net crashes:

Anyone has an issue like this one? Anyone has some sort of solution for this?

Thank you

That used to be a common bug with wow and mb's. It was due to a conflict in drivers. Updates have solved it. Most of the time the increased heat from gaming would trigger the internet disconnect. If you have done all the updates and still suffer from the net disconnects theres a chance you have a damaged airport card. Of course Im talking about 10.4-5 and 10.5.1 so if you have these versions of the os its time to update them. In the mean time you can keep your fans on a little higher with smc fan control, always game on a hard surface (never soft like a blanket or pillow), and worst case use a wired net connection.

the problem is i am using a wired connection, i have all the updates (at least i don't have anything on software update) and my macbook is always on a table above 2 books (to let the air flow in between). Could the books be the problem?

 

[Keytachi]

the other day i was using a wireless connection, and the same thing happened. I'm beginning to think the heat may be the problem. I always have smc fan open, and the fans are always maxed out, and the CPU temp is still at 80ºC :S
Should i buy an external fan? (the berkley thingie to put under the computer)

 

[Keytachi]

ok, this is getting out of hand.
Today, after yet another reboot, i went to my grandmother's house. I opened Azureus and Safari, and left the fan working top speed. When i got back i had lost the internet connection, again.

Anyone has any idea of what may be happening? I'm driving crazy!

bumping this for my sanity's sake

same here

Hey,
I have exactly the same problem on my Macbook (late 2006). Graphics intensive games seem to crash my network (both ethernet and airport). I think this is a hardware-related (rather than driver) problem because it occurs both in 10.5.3 and 10.4.11.
Because this happens even when my MB runs well below 80°C, and also sometimes I get shutdowns when moving lots of data over firewire, I came to believe that it is not related to heat but rather to the heavy loads of data being moved around between cpu, graphics card, ram, i/o busses, etc.
I'm afraid our hardware might be about to die…

I have this problem too... 1.83 Core Duo MacBook bought in mid-2006. I have 2 GB of RAM and this happens when I play Warcraft III and even sometimes when I watch flash videos in full screen (most notably on southparkstudios.com). I have the latest edition of Leopard installed.

Could this be due to the MB's crappy video card? If I got a MBP, with its dedicated graphics card, would this problem be gone?

 

[litachao]

Yeah, an MBP should solve your probems.

This really sucks, crappy performance is something I could live with, but with instability due to heavy workload I can't. Just yesterday my Macbook just shut itself down while doing a time machine backup, power off, just like that.…

Does it happen when Azureus is not running as BitTorrent can flood the connection causing modem/router or internet connection sharing lockup ?

Hi!

I just purchased a MacBook Pro and I get the same error when I play WoW as well. I have nothing running in the background, the system has the dedicated card, it shouldn't be an ISP issue because of successful connections on other computers. Resetting the PRAM and Power control thingy (Apple Support walked me through that yesterday) was all unsuccessful.

I just installed SMC Fan control and am running at about 42C at 4k rpm. It takes about 2 minutes from launching WoW until the entire system hangs and video drops completely.

I am running 10.5.4 and have patched as far as I can find. Nvidia does not have drivers or anything for the 8600M chipset.

Does anyone have any ideas?

Thank you!
