i think problem solved. because i dont have a wpa crash and i work it for a while.this is what i did. i had reached in a situation not to be able to open the system and then disconnected.thats what i did: 1,from synaptic i completely removed network-manager-gnome and pptp, updated ane upgraded 2, i wired the internet. 3 . i from the setup option disabled the wireless . booted and entered recovery mode and made the following steps : enable network, update grub, update and upgrade and then fix broken. then i installed network-manager and i had to remove some packages network that no needed. rebooted and did the same from the recovery twice. login in then gedit showed some strange thinks about lo connection.so it was the bluetooth as there was again a linksys connection open, i guess through bluetooth-which in every login reanabled itself-ALONE-.so from setup finally i disabled bluetooth and no linksys.thats it
