I was noticing my picture quality isn't as sharp as it was when installed 2 weeks ago, upon checking the signal quality it's coming up as 'Fair' rather than 'Good'. I did recently have an engineer come out and he fitted two 6db attenuators to both points. Could this hinder the signal or possibly down to the weather?
That script of information I got from the router but you can do a diagnostics check on your 360 box; my signal quality fluctuates between 'fair' and 'good'. I'm sure the previous engineer said I was getting too much before but now it seems worse all round. I may just cut my loses and call it a day and go down the NowTv route.
