WiFi Connection Issues?

[ksukhin]

I just re-installed Yosemite on my rMBP and I'm having this annoying issue with wifi networks.

There's this unprotected "linksys" network and my laptop keeps connecting to it, even though I'm at home and my own signal is stronger.

I've removed it from the "preferred networks" but it keeps reappearing.

I want to say it has something to do with keychain or iCloud but this is where Im lost.

None of my other devices (iPhone 6 and iPad Mini) do this. They connect to the right network 100% of the time.

Please help!

I've gotta ask, do you have 'ask to join other networks' checked? I just looked to see if preferences allows you to set channels manually but it doesn't. Setting the wrong channel for that network was the first thing I thought of.

I do not have it checked. My mac knows my password for my protected network, but it still chooses to connect to the "linksys" one that does not have a password

Yeah, just thinking out loud. Have you tried the Keychain Access app and looked for a linksys entry in the system keychain?
