losing ESSID

Hey guys, facing a weird issue - hoping someone might be able to help.

The wireless network on my laptop is configured with a static IP address. (not using nm)

When i take the laptop out of the range (or i power the router down) the essid is becoming "off/any".

When i'm back in range the connection is not reestablished and to re-enable the connection i gotta reconfigure the essid "iwconfig wlan0 essid <essid name>"

Anyone knows how to avoid that and make the essid stick unless i want to change it manually?

NAME
wireless - Wireless Tools and Wireless Extensions SYNOPSIS
iwconfig iwpriv -a DESCRIPTION
The Wireless Extensions is an API allowing you manipulate Wireless LAN networking interfaces. It is composed of a variety of tools and configuration files. It is documented in more detail in the Linux Wireless LAN Howto. The Wireless Tools are used to change the configuration of wireless LAN networking interfaces on the fly, to get their current configura- tion, to get statistics and diagnose them. They are described in their own man page, see below for references. Wireless configuration is specific to each Linux distribution. This man page will contain in the future the configuration procedure for a few common distributions. For the time being, check the file DISTRIBUTIONS.txt included with the Wireless Tools package. DEBIAN 3.0 In Debian 3.0 (and later) you can configure wireless LAN networking devices using the network configuration tool ifupdown(8).
