How to make a network the preferred one?

[DianeK]

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

I'm not at my Mac right now so I don't have the exact wording, but it's something like Sys Prefs > Network > Wi-Fi > Advanced > Drag and drop networks into the order that you want.

It should also be possible to go into the setup of the modem/router from your ISP and disable WiFi there completely. How to get into this setup should be explained in the manual that (hopefully) came with the modem/router.

Then your Mac has only the WiFi net from your Time Capsule left to connect to.

Thanks. Mission accomplished just as you described. So I'll see if this holds on the next wake-up.

For some reason, my husband would prefer to not disable the modem's wi-fi . I now have our Time Capsule at the top of my list so hopefully my iMac will stop trying to connect to the modem.

Thanks to both of you for your help!
