==> The highlited entry representing network that you are connected to has an icon left of the ESSID. If this icon is grayed out, it means that you are successfully connected to the AP, but the internet is not reachable. In this case, the problem is most likely on the AP side. If the icon is in full-colour, it means that both AP and Internet are accessible.
==> Increasing the DHCP Timeout option might help if you have trouble connecting to some networks. However, before you do increase this value, double-check that all other settings (esp. WEP) are set correctly.
==> If it takes a long time to detect an existing connection, you are using a DHCP client and message "...from 'route'" appears in the console, you might want to edit wlassistantrc and make sure that DHCP PID Path and DHCP Info Path for your DHCP client are set correctly.
If you delete these values from the config file, they will be reverted to defaults next time you run Wireless Assistant.
