Well, actually the disconnect issue appeared at first only when I suspended my laptop. This prevented me from using STR on my laptop.
Then, it stopped (About 2 months ago, I think but not sure). Then, it reappeared with the disconnection also appearing whith no STR, so I posted this bug. I suspended my laptop at ~ 6:30 am and wake up at ~9:30 am, I had no more wifi. I had new messages repeating in dmesg, I cut it and is attached. ** Attachment added: "dmesg STR.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1096853/+attachment/3499667/+files/dmesg%20STR.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1096853 Title: 14e4:4353 Wi-Fi disconnects then cannot connect to any network -- Broadcom BCM43224 bcma To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1096853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
