Comment 0 for bug 1525270

A few minutes after booting my Samsung R580 laptop, the Wi-Fi disconnects and it fails to reconnect until I restart the machine. This happens with all the 64 bit versions of Ubuntu I tried, from 14.04 to 15.10. With the 32 bit versions, everything runs perfectly. No loss of connection at all, even after 48 hours in a row.

Here is the output of iwconfig after loss of connexion:

eth7 no wireless extensions.

lo no wireless extensions.
