Ok, thanks RMerlin - I have updated to fw .18B and it loks good on the wireless
log. Just an issue left : the unexpected disconnects when I am in the web-gui
of the router : The connection has timed out
The server at 192.168.2.1 is taking too long to respond.
After this message I can not reach anything on internet and no respons on
ping or telnet from the unit. The status on the wireless in Windows is connected
on internet and the speed is 270 Mbps - as before the disconnect.
When I leave it like that after a period of time the connection is reestablished.
Then I can reach the web-gui and the internet too.
Sounds like an issue specific to either your router or your environment, as I see no other report of that issue. Look for the usual: setting a manual channel, dropping bandwidth to 20 Mhz, updating your wireless drivers, etc... One change Asus did in build 220 was to re-enable automatic interference management, so that could be related to your issue if you are in a noisy environment.
