Upgraded to windows 8 now I am losing my connectivity every so often!

Hello I run an m17x R4 and it was originally windows 7, but of course I upgraded. Everything was great until recently I have been experiencing my wireless connection cutting out at random times. It can space from every 5-10minutes up until an hour.

I have tried everything possible that I can think of too sort this problem but too no avail, so I am wondering if you guys here can help me.
