Here's the problem. MacBook 2.16, just upgraded to 10.5.3, experiencing massive hangs in all my browsers (including IE & Firefox in Windows using VMWare) when loading almost any page (but downloads seem to breeze along--the 10.5.3 d/l came in at over 1.6MB/sec). The symptom is the page will start to load, then beach ball with a progress shown as "26 of 27 items loaded," or similar reports of one or two elements just not passing. Some of the time, the page will finish with graphic elements missing, others it'll just time out. What I've checked: Wired & wireless through Airport Extreme and wired directly to the cable modem. DNS is fine, just grabbing my provider (ph.cox.net). One issue I have seen is when this happens, a look in Activity Monitor shows the NETServer process not responding. Using my G5 iMac wired has not had fewer problems but just loading this Post New Thread page brought up 20 errors. I'm haven't lately installed or used any apps or utilities that would be reasonably expected to clobber it so suddenly & completely. Cables, phone, electrical, all the other local environment factors haven't altered in months. Everything's been rebooted and settings inspected a dozen times, but I'm at a loss, even looking to Archive & Install just to see if I've gotten some unexpected clutter or corruption. If that doesn't resolve it, I can restore from the SuperDuper! clone to bring me back to this morning's configuration. The common factors: 10.5.3 on both machines, the Airport Extreme (but I think I've eliminated that), the cable modem (LinkSys BEFCMU10), and the ISP (Cox). Any good guesses?
