Good to learn that all is well. My connections differ from yours because of my problems with the ID41: I cannot get it to work with my TalkTalk router. I am therefore using a USB connection in both zones. I would rather have used the ID41 as I think that USB is inherently noisier.

I bought each filter with 1m of their ethernet cable that is on special offer. Shamefully, I have not tested whether the cable brings any special enhancements as claimed!
