Hi, I'm having problem with my wireless connection. It manages to get connected, but from time to time it gets disconnected. Also sometimes it fails to connect to a wireless-n. I have not managed to figure out what triggers this disconnection. These are the outputs I thought could help clarify what happens:
uname -a
lspci
dmesg
I have also NetworkManager log, wpaSupplicant.log, and the complete dmesg. Let me know if they are needed.
Thanks in advance for any hint you can give me.
