I have two Homebuilt XP machines that are 5 years old, they’ve both been running constant with no reboot for over a year, and they have no problems with this ((enter extreme sarcasm zone)) “new fangled” WiFi router connections.
If age is the problem, then Apple REALLY screwed the dude I got this thing from.
I was really looking forward to having one of these machines, now I know they’re over-hyped. No doubt.
No, age isn’t the problem, but there’s no sense in comparing old to new.
As for your G5 - is it completely stock including an *Apple* Airport card? Which card is it? Did you check to make sure it wasn’t one of the defective Airport cards they recalled a few years back?
Oh, by the way, your claim about the XP boxes running without reboot for a year? That means you’re at least a year behind on your updates... and it means that if I can get your IP address, I can own both of them with just a few commands.
Congratulations, you just advertised to the world that your XP boxes are wide open for net raping.
