1. Drop your firewalls while troubleshooting, regardless of whether or not you think they have nothing to do with the problems. One less variable is one less variable.
2. If possible, connect the problematic machines via Ethernet as a test. IOW, determine if the problems are only related to WiFi, or not.
3. Do the page-load problems occur only with one browser, or do any/all web browsing programs exhibit the problems?
4. Do your system and/or application logs hold any clues? Open the Event Viewer utility in your Administrative Tools folder to view the logs; look for entries indicating network-related warnings or errors.
