Well I posted earlier that my DGL-4500 with the 1.20 was all of a sudden crashing like CRAZY today. The internet would work for a few minutes then freeze. I tried everything possible to track down why it was doing it. I have Fios 20/5 internet with the DGL-4500 as the sole router. I have two computers hardwired to it along with a color laster pinter. I also have three wireless devices attached to the router. I didn't really experience any issues since loading the 1.20 firmware last week until late last night.
After doing everything possible, I found the cause of the problem (which was the strangest freaking thing). Apparently, a Virtual Machine of Windows Server 2003 on VMWARE would cause the router to crash. It even caused the verzion actiontec router to crash. I had this VM running about two weeks with no issues. We use it to stream audio and my partners have access to it via logmein. Apparently, something happened to the VM late last night that was causing my router to crash. Once I restored a snapshot of the VM from a few days ago, the problem was fixed and everything is fine again. I really don't get what happened.
