don't know if it's the firewall doing this, it happens off and on, so not every time, when the system wakes up from sleep mode I got to wait about 30 secs up to one minute until I can connect to the Internet (although the taskbar network icon looks OK, wi-fi is running properly, message is Internet is there
). I said the firewall but it could be the web shield too, as when you manually stop it and reactivate it, you don't get internet access immediately in a browser.
ps: in such cases, again, my connection is not lost, as it can happen after sleep mode, for power management issues. So it's not that.
