Hi,

OK, NM is running fine since I last booted, no hangups as yet.

When I run  'iwlist eth1 scan'  the results vary. Sometimes I get 

root localhost ~ > /sbin/iwlist eth1 scan
eth1      No scan results

if I try again straight away I get

root localhost ~ > /sbin/iwlist eth1 scan
eth1      Scan completed :
          Cell 01 - Address: 00:0C:41:9B:26:88
                    ESSID:"8MarfieldCourt"

which is my network. Sometimes, I also get other neighbouring networks

root localhost ~ > /sbin/iwlist eth1 scan
eth1      Scan completed :
          Cell 01 - Address: 00:0C:41:9B:26:88

Does this indicate my signal strength is weak ( I did recently move my 
wireless station a little, although it is still next door about 5 metres away 
so pretty close)? NM always reports exactly 100% on the icon applet, which 
does now I think about it seem a little odd - Shouldn't it occasionally dip a 
little ? ( Also, I have NEVER had the little bar charts working when I left 
click on the applet - IS this also something I should worry about ? )


many thanks
