I was using a D-Link I-604 router in a home network situation (3 computers, WK2SP4 and cable modem). I've been plagued with memory leaks with ALL 3 computers when using this setup and accessing internet. Randomly, I will start to lose content on web pages (blank areas, text missing, etc)...then I will start having memory issues with MS Office (specifically Access, Excel)...as I said, this happens randomly with all computers (memory on 2 boxes is 256mb, other box is 1 gig). I have been in touch with D-Link support several times; they had me update the firmware, had me make changes to IE6 configurations, etc....nothing has worked. When I go back to Zone Alarm for my firewall; i.e., then everything (web browsing, Office apps) works fine..As a last resort, I e-mailed D-Link again, detailing whats going on....this time they never got back to me. What is interesting, is that I tried a Linkys router, and the same thing happens.....so now, I am really confused ..(maybe there are "ghosts in the machine")...any suggestions??
