ok, look at the following tables 
I a have a dual boot on this machine with 6.3-R and Current and compare the 
RSSi values. Same hardware, time difference only the minute to reboot and no 
config changes, simply booting 7.0 the RSSI drops and this is not only a 
cosmetic issue, definitely the signal strength is lower on the client too. I 
have sorted the macs so you can directly compare line to line, the last 
column is the RSSI, The machine is already with the new ifconfig compiled 
after your update yesterday night.
