Hi there, I have solved this issue on my Linx 1010 and hope this will help others.
This problem has been bothering me too. I don't use my tablet for wifi often and have found it drops the connection on sleep, hibernate etc. After a lot of hunting I found this is down to the automatic power saving settings on the network adapter. The issue is not simply a lack of power but an exchange of control commands with the router: some routers can complete the exchange and some can't which explains why wifi works on some routers and not others. What's happening is the router is supposed to spot 'idle' wifi use and 'agree' to the reduced power state on the tablet- and when the tablet demands a higher power draw the router is supposed to respond. Not all routers have this function...hence the drop outs.
A fix for this is to tweak the power saving settings for the network adapter but the Windows 10 install on the Linx1010 has limited controls ( you can't set a power profile for 'maximum performance' for instance).
From the Windows 10 forums You need to be registered to view this link, please log-in or register
I found the missing setting can be restored by a registry setting (type 'regedit' in the start area to open the registry*):
There are a couple of registry hacks you can try.
First, go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Change CsEnabled from 1 to 0 and reboot.
This enabled the settings in Windows Power Options (right click on windows start select power options ) for 'maximum power' to be applied and this means the network adapter powerstate message is not sent to the router.
As well a giving control via the Power Options panel the registry edit opens power managenment settings for the adapter in device manager (I unchecked 'Allow the computer to turn off this device')
This will reduce battery life but will allow the browser session to be hibernated and awoken sucessfully without a conflict with the router.
*editing the registry can be dangerous take great care care with this!
I hope this is helpful,
