As a followup to my previous post, after the last firmware upgrade (claiminig again an "improved stability" in the changelog), I started experiencing regular disconnections, both from the WiFi and from the ADSL line. So, on August 12 I decided enough was enough and reconnected my old router (Linksys WAG200G).
Here is my provider connections log:
In the last five days I used the SX763 it disconnected more than 20 times, now I am STILL running the connection started at about 0:30:00 !!!
Dear Siemens, please take note...
