Intermittent Broadcom wireless dropouts -- anyone else getting this?

Hi guys, happy weekends. I'm making good progress with Bunsen on the Asus X205T, to the point where I'm typing this on the machine and will post using the inbuilt wi-fi. I'll submit a report/install guide on the "install" thread when I'm completely done. Meanwhile...

I'm getting an irritating wi-fi issue, wondered if anyone else has similar?

Out-of-the box X205, 64bit Debian vanilla, BL netinstall.

When first booted, no wi-fi visible under Network-Manager in the system tray. I did these things:

sudo nano /etc/NetworkManager/NetworkManager.conf

Changed "managed=false" to "managed=true", saved&closed.

sudo killall NetworkManager

Rebooted.

Result was that N-M worked perfectly for the next 10--20 reboots. This morning it didn't -- until I did sudo killall again.

Not a huge problem but irritating. Anyone got a permanent fix?

NP.

That alteration lets NetworkManager handle all interfaces, even if they are listed in /etc/network/interfaces

You can try using the latter method instead by reverting your change and following interfaces(5)

However, as you have a Broadcom device I am going to presume that the blame lies there -- Broadcom support in GNU/Linux is terrible

What is the device?

lspci -knn|grep -iA2 net

Post your dmesg output from when the connection drops; almost certainly you'll see a bunch of driver errors. A few months ago I set up Ubuntu 15.10 on a Mac Mini server 2012 with broadcom wireless. Literally none of the available drivers worked (even though the chip is supported by all of them) and I had random issues (connection drops, random downgrading 5Ghz->2.4Ghz, reception issues). It's garbage. I ended up using a ethernet cable.

Hi guys, sorry for slow response -- been tied up on other projects. Thanks. I guess your bottom line is: everyone hates Broadcom. I'm going to post a real-world X205T wrangling article on this thread: https://forums.bunsenlabs.org/viewtopic.php?id=1701 but still have a couple of bugs to work out. Best NP
