Wireless password problems

[chopper1]

since i installed the new patch 11th Nov every time i turn on the receiver it is not connecting wireless automatically, i have to manually put the password in each time and this did not happen on previous patches, what are the other 2 red sybmols with lines across them for?
Is there any easy solution to this?

Just turn to wired .
Then exit and then again go to Network menu and change to wireless .
I used the same way in previous patches when i plug it off from the main .
