Sorry but I didn't know or find that 8.1 is shipping on this make and model. Go back to what the maker supplied.
Wish I had more to work with but as it stands you are out in the unsupported zone.

I've got Windows 8.1 on my test PC and haven't run into this problem, but I'm only a few feet away from the router and probably have a different WiFi card from yours.
The problem can be because of WiFi congestion problem, so all you need to do is just open your router setup in the browser. Go to the wireless LAN setup and change your WiFi broadcasting channel from 1-11/13. Lets say if your channel is being set to highest or lowest one the make it in reverse order to select a middle channel. In this way your WiFi congestion issue will be resolved. Thanks
it seems that : your device goes away after awhile
because of power management
and you need to disable this
here's how to fix this with pictures

I had a randomly dropping wifi connection as well and tried all the settings mentioned in this thread and elsewhere on the internet (different channel, fixed channel, turn off usb powersafe, no 802.11b/g mixed mode, do not mis-type the wpa key on windows xp, check wifi sending power, ...), to no avail.
the solution for me was:
within a foots range of the wifi antenna a wall plug was not plugged in correctly, problably causing disruption to the wifi signal. i pushed that in properly and the wifi is now as stable as it ever was.
perhaps there are other disruptions to your waves, e.g. a crt screen, coffee machine, usb-powered devices next to antenna etc.
