Recently my wifi has started dropping at random times. I've looked for answers and tried:

using the original firmware drivers from the install disk

using the latest firmware drivers from github

using the firmware drivers from ubuntu 16.04LTS

using a different browser

every different combination of board.bin, board-2.bin, firmware-5.bin and firmware-6.bin, old and new versions

setting a static ip address,

a complete reinstall of Ubuntu

yet the problem won't go away. I didn't have this problem when the machine had Windows 10 on it, nor for the first couple of years with ubuntu.

Also the output of ping varies - sometimes it's "network is unreachable", sometimes "Destination host unreachable"

Sometimes I get a question mark in the taskbar, sometimes a blank space, but it can still detect the network.

Please help before I launch the laptop into the ether and go back to Windows.
