I have a laptop what has WiFi on the motherboard, but it only supports 802.11a/b and WEP. My WiFi network is 802.11n with WPA2-Personal. So I purchased a USB wireless stick that's compatible with my network. Now I have two wireless NICs. I am running Ubuntu 14.10 Desktop.
My network also has an open wireless network for guests which supports any security and so I think my motherboard's 802.11a/b NIC is connecting to my guest network randomly.
I'm finding that my laptop is wandering amongst all the possible connections.
- How can I disable the WiFi card on the motherboard?
- How can I set my USB wireless to connect using only a specific connection?
I didn't create all of the connections on the laptop and when I click on the wireless icon next to the system clock on my desktop, then Edit Connections, all of these connections don't show up so that I can delete/disable them. The one that does show up is the one that I want to connect to, but there isn't a setting to connect to it ONLY.
