3. > The full manufacturer and model of your computer as noted on the sticker of the computer itself.

Manufactuurer: HP
Model: 15-ba061ur

4. > Did this problem not occur in a previous release? If so, which one(s) specifically?

No information: I haven't installed any of the previous releases to this notebook. It is the first Ubuntu on it - and it has this issue.

5. > Does this problem occur with the latest version of Ubuntu?

It happens with the latest version of Ubuntu 16.04 - I have all the upgrades installed.

6. > If available, please comment to how testing the relevant open source driver for your card type provides a WORKAROUND. If your chipset is supported as per above, but doesn't work, please file a bug following the b43 driver procedure below.

Didn't get the question) No known workaround - at least for me.

7. > Please provide the router manufacturer, model, and firmware version.

Manufacturer: Zyxel
Model: Keenetic Start
Firmware version: 'NDMS 2' 2.09.C.0

8. > Please comment to how testing ndiswrapper for your card type provides a WORKAROUND. If it doesn't work, please file a bug report as per the support article.

Didn't understand what I am supposed to do, sorry.

The bug itself in my case is not entirely "can't work" - it is working for some time and then stops working, needing restart of the connection or (if it doesn't help) network-manager or (if it doesn't help either) the notebook itself. It is very annoying to be in such "dualistic" state: it is simultaneously working well a...
