Ok think i`ve fixed it. Took dog out this early this morning got home and radio off again, sure enough lost packets so went outside and fiddled with the cable that come in the house and sure enough it worked!!
So I took out the joiner that joined the two cables together replaced it and put it back together and as you can see things seems to be much better :-

If you look at the end of the graph beyond when it started again this morning you can see it`s starting to stabilise.
Will keep you posted and thanks again for all your help
