Further steps to reduce Wi-Fi exposure
Be sure all the accessories for your tech are corded not wireless.
RJ45 to USB – links often go out of date so google that in amazon
RJ45 to phone/iPad (lightning port) – links often go out of date so google that in amazon
If you don't have Ethernet points, then you can use a TP link system (TL-PA8010PKIT) to pass the ethernet down the power lines, but these do give dirty electricity. Arguably better than constant wifi however. https://smile.amazon.co.uk/dp/B0734B71N6/ref=pe_3187911_189395841_TE_dp_1
Change to a non-wireless router and use wired systems for linking multiple computers.
Use your Broadband service provider’s smart hub manager page to turn off just the WiFi – ethernet will still work. BUT beware some modems only switch off the connectivity and NOT the signal – this happens with BT modems because they use your modem to provide their mobile BT with Fon service.
Eco Wifi routers – these have adjustable settings, and so are easy to turn off/down. https://www.jrseco.com
Minimise your time spent in Wi-Fi hotspots.
Minimise time overall on wireless devices and teach your children about this issue so you (and they) can be less exposed when you hang out with them.
When not in use keep the router and laptops away from children and switch off at night.
Locate screens in family areas—not in bedrooms.
Especially children - avoid screens 2hrs before bedtime. Melatonin disruption can adversely impact human health.
