The problem started when I upgraded my new (3 days) windows 8.1 laptop to win10. Wifi networking worked nicely on 8.1, but after the upgrade, the wifi adapter is very slow and randomly reports 100% signal reception and then drops connections. It then may return to a connected (but slow) state for 2 minutes before dropping again or connecting in limited
connection. It only does this on my home network. updating drivers did noting.
I discovered with a little bit of research that the BCM43142
is known for the above described behaviour on systems as old as windows vista, but I did found any solutions for that problem.
Edit: as I write this, I didn't experience any disconnections of any sort, nor extreme slowness for about 2 hours straignt.
An alternative may be HomePlug (Ethernet over electrical wires) possibly faster as well. Supports gigabit class speeds. i.e. plug jack into electrical by router, connect with ethernet. then plug second jack in power jack where notebook is wanted and connect ethernet to notebook.

I have a similar issue. Pls see http://superuser.com/questions/1023244/windows-10-wifi-connection-drops-throughput-issue

Mine involved the adapter reporting absolute 100% signal seconds before dropping, regardless of the distance between the adapter and the router. In your case it seems to be a power-save mode problem. – RetroDroid – 2016-02-23T07:04:58.980
