after upgrading to 16.04 my wifi randomly drops. Often a few minutes after startup but sometimes after multiple hours. I am dualbooting Ubuntu on Microsofts Surface Pro 4.

Output of "lspci -knn | grep Wireless":

02:00.0 Ethernet controller [0200]: Marvell Technology Group Ltd. 88W8897 [AVASTAR] 802.11ac Wireless [11ab:2b38]

  • Welcome to U&L , to see the kernel module in use please update with the output of `lspci -knn | grep Net -A2` – GAD3R Sep 14 '17 at 20:13
  • @GAD3R: `lspci -knn | grep Net -A2` won't generate an output. what does this mean? When i startup in windows and look up the network adapters these are shown: Network adapters: Marvell AVASTAR Wireless-AC Network Controller; VMware Virtual Ethernet Adapter for VMnet1; VMware Virtual Ethernet Adapter for VMnet8; – Kokonut Sep 15 '17 at 10:10
  • `lspci -knn` and see the `Kernel driver in use: ??` and `Kernel modules: ?? ??` – GAD3R Sep 15 '17 at 10:15
  • @GAD3R: `Kernel driver in use: mwifiex_pcie` and `Kernel modules: mwifiex_pcie` – Kokonut Sep 15 '17 at 10:34
  • from Grub menu , select the advanced option of Ubuntu then try to boot an old kernel – GAD3R Sep 15 '17 at 11:52
  • @GAD3R: In the grub menu only 3 options are offered: `Ubuntu with Linux 4.10.00-28-generic ` and then two of the same version with the addition of `(upstart)` and `(generic)` . I tried all and connecting still dropped, how do i load additional older kernels to the grub and which one do you recommend. – Kokonut Sep 15 '17 at 12:46

After reinstalling the system on Ubuntu 14.04.05 it works.
