Just to throw in my two cents' worth - I'm running a HP Pavilion dv6-3120us laptop, fully updated PCLOS wicd NOT installed.
I have no trouble connecting to my wireless network using netapplet, and it also shows both mine and my neighbours' networks when I right-click it.
However, if I then click on "Manage wireless networks" it takes me to the PCC wireless connection screen, showing no wireless connections whatever.
The same result if I access the PCC wireless connection screen via PCC.
The only way to edit a connection is to right-click the netapplet, then select the individual connection at that point.
Beats me! Just pleased that I have no connection problems
