I seem to have solved my wi-fi flakey issue with ML. We have a cabled wi-fi modem/router from our isp and we have a Time Capsule ethernet connected to the modem/router. My wi-fi is stable if I select the Time Capsule network but squirrelly as all get out when connected to the modem wi-fi. Problem is it seems that the modem is the default, so when the computer reawakens its preference is to connect to the modem. So how do I make the Time Capsule network the default? Sorry, I guess that was a little long-winded
