Wifi adapter disconnects after sleep. Sleeping and powering back on reconnects adapter












0















I am having a consistent problem with my laptop where when I put my computer to sleep and open the lid my wifi adapter disconnects. The adapter doesn't show up at all when I run the following:



lspci | egrep -i --color 'network|ethernet'


and when I try to restart the network manager using this:



sudo service network-manager restart


that does not help either.



Here is the output that I get from checking how the kernel recognises my network card.



$sudo lshw -class network

*-network
description: Wireless interface
product: QCA6174 802.11ac Wireless Network Adapter
vendor: Qualcomm Atheros
physical id: 0
bus info: pci@0000:3a:00.0
logical name: wlp58s0
version: 32
serial: 9c:b6:d0:13:19:c3
width: 64 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless
configuration: broadcast=yes driver=ath10k_pci driverversion=4.15.0-43-generic firmware=WLAN.RM.4.4.1-00079-QCARMSWPZ-1 ip=10.217.4.55 latency=0 link=yes multicast=yes wireless=IEEE 802.11
resources: irq:131 memory:dc000000-dc1fffff


The only solution that I have found that consistently solves the problem is to close my laptop and let it go to sleep and then power it back on again.



I have even checked whether it is a hardware issue by taking apart the laptop and making sure that the connections to the wifi chipset antenna don't disconnect when I open the laptop or move it around. Because of this I am fairly confident that it isn't a hardware problem.



I am running Ubuntu 18.04 currently.



I am at a loss for what the problem could be with my wifi. Any ideas are greatly appreciated.
