Alienware M15 R5 wifi connection issue

bit of an od one but my alienware M15 R5 is having a wifi connection issue, basicly when only at home on my BT router, not my work wifi it drops in and out every minuet or so for about 3 mins then just disconnects and wont reconnect to the internet. i have tried all the usual basic stuff uninstall killer drivers, re download drivers,  no change, i have changed the wifi card to an intel one but still the problem persists, in teh event log of the network adapter it does come up with a problem starting message but its doing my nut in now and any help will be massivly appreciated.

i have attached a picture of the event log if this will help anyone.

thanks in advance
