@Thanks for that @legacy1. Yes, I'd guess that it must be related to Docsis so I'm not sure how to proceed. Perhaps I'll need to go back to a lower bandwidth solution through the telephone, though I'd rather stick with cable if possible. I'm going to try shielding the router with some appropriate material. I know most people want blazing speeds so I must be in the minority to want to cool it down. I came across a JRS Eco Wifi router but perhaps in my current setup that wouldn't be an option. Again, thanks for pointing to Docsis as I really hadn't heard about it.
Is it really worth the effort of going out of your way to block EM emissions from the Hub when chances are your neighbours also have wireless networks, and even if they don't there are a plethora of signals transmitted on various bands, AM/FM radio, GPS, 2G/3G/4G networks, etc.
The non-ionizing radiation at regulated power levels isn't going to do any harm to any organism, unless that's not your concern and it's actually to do with interference with other appliances.
Thanks for replying. I've put my router in a Shredded Wheat box and covered it with aluminium foil which has reduced the RF a couple of notches on my EMF meter. I'm feeling better already! I know what you mean about neighbours' networks etc., but I only wanted to reduce the overall 'radiation' which is well-known to harm organisms long-term from what I've discovered - it's just that those who really know this aren't telling us about it!
