I have had this unit since January 2010. I have it send me reports via email every hour so I know it is in an up state and to look at some of the reports. My issue is this first I notice that the email stops reporting. The next thing to stop is wireless -N computers (both Vista Ultimate 64bit and Windows 7 Ultimate 64bit) Intel wifi cards. You can see the wifi signal strong but you can't connect. Next it will drop iphone/slower computers with wireless-G. At this point I will try to log into the unit console and it tells me my user name and password are incorrect. I cannot log into it remotely or even RDP to any of my servers/computers. I will look at the server ( Windows 2008 R2) and the Cisco Configuration Assistant has lost connection.
I am left with no choice but to power it off and back on. This will happen over a period of 2 to 5 days. It has been going on since I put it into service.
I have added another SA520W in another property of mine in June so I could VPN them together. It was added in June. It has had absolutly no issues what so ever.
I can stream security camera video over it with no problems. But the VPN drops on the side of the SA520W I am writing about.
