Update downloads keep stopping.......

For some reason, whenever I try to get updates (either via Software Update or by manually downloading the needed updates from the Apple site), they always stop (sometimes @ 5 MB, sometimes @ 9 MB, or whatever MB). Has anyone else experienced this?? I have no problems updating the PC that is in the same room as my Mac. In fact, it is downloading & installing updates right now for iTunes & QuickTime without any issues. This has me puzzled. My internet service provider verified the line & found no packet losses. Any input will be greatly appreciated. Thanks in advance.

G5 2.0 DC/Pismo 400, Mac OS X (10.4.9), 5.5 GB, 16x DL DVD Burner, Nvidia 6600 LE/512 MB, Still going strong

Unfortunately, changing the MTU setting for the Airport card requires using the command line, & from what I have read, you have to do it every time you restart your machine. Apple technical support could probably assist you with a way to do it permanently, but I do not know how that would be done. However, if you want to do it for your ethernet port, open up System Preferences, then click on Network. Be sure that the ethernet port is selected, then click on the Advanced button. A new window will open where you will click on the Ethernet tab. Once that is open, click on the drop down list next to Configure (it will be set to automatically), then change it to Manually. Go to the last drop down (where it says MTU:) and select Custom. In the box that appears, type 500 (you can probably use any number less than 1492 - but bigger than 72 - and it should work). Then click on OK, followed by Apply (back in the main Network window). This should do the trick for the ethernet port. If anyone knows how to make it work with the Airport card, please let us know. Thanks.

I have the exact same problem on a brand new Early 2008 MacPro. Leopard 10.5.1 - Have confounded my IT staff and my ISP... Nothing wrong with the routers, the cisco switch, or any other mac in my office. This is the only one running Leopard... I'd start a dl and for about 3 seconds everything would blaze away at better than 500KB/sec but drop to 0 over the next minute.

Tried everything but the suggested above change in the MTU... set to 500 and the downloads, while slower actually don't stop but chug along at around 200KB/sec. So, at least there's hope in getting updates, etc.

Nothing larger than 500 in the MTU works, though... Sys Prefs > Network > Advanced > Ethernet > Configure: Manually ; MTU: Custom; 500; > OK > Apply...

I'm really hoping this is a driver issue, or at least something fixable...
