After a couple of days on 10.2.4 where I noticed nothing wrong, my cable modem connection turned into a trudge through toffee, when I got one at all!
At first, I thought my ISP was playing up, checked all the panels on the machine, but swiftly found that I was far from alone.
Things were particularly bad when my Mac woke up from sleep. Every site was like TS has occasionally been on an "off day".
Trouble in various shapes has led to several threads on the Apple discussion boards, at MacNN and MacInTouch.
Sadly, there is no one single fix reported, and lots of people are yelling for Apple to do one.
The high life returned to my own Net connections when I opened the Network Preference Pane, went to the "Show" bar, chose "Network Port Configurations" and then switched off "Internal Modem" to leave only "Built-In Ethernet". This is not immediately obvious and both are on by default.
For good measure, I also fetched and ran the combo updater, which I'd been meaning to stash away anyway, and which somebody else found helped on an eMac.
Don't ask me why the latter made any difference, but I've had no trouble since.
Apart from eMacs, machines particularly at risk include iBook 800s, from what I've read.
For dial-up modem fixes, I've seen a host of notions elsewhere, including some that involve fiddling around with the terminal.
So - if you're thinking of "upgrading" to 10.2.4, and especially if you're on dial-up and can't use my fix if things go awry, you might want to search around and check out modem issues before doing so.
