Hello,

my PC WIFI(Qualcomm Atheros QCA61x4A Wireless Network Adapter) when connected to TP-Link router (TL-WR840N), internet works fine, until it doesn't get loaded.
Meaning, if i turn on torrents or any long HQ youtube video. After this it turns off in 2-3 minutes.
My wifi still shows in the list, but just can't connect to it anymore. Neither from my phone or a laptop.
Only router restart helps.
Logical conclusion would be that router can't handle the "pressure".
But
I also have Hama Wireless USB stick, using which the same problem never happens. which means that it is not router problem. But if it isn't why does router needs a restart in case of my PC wifi? (?)
can you please help me out, this is a very confusing loophole.
 
Solution
go to device manager, click on network card, click on power management and turn off any power saving settings/ turn on wake up when accessed/ always on/ etc.
