I realised that the Virgin "Super Hub" was a bit poor in the Wi-fi area, so I used the old Virgin hub as a repeater and this worked much better. Gave me all the cover I needed including the back garden and in the car at the front (VCDS updates as needed when I'm out the front).
Zyxel came up with some repeaters and I tried three. Scattered them around the house with the first alongside Super Hub. Left the super hub in normal use. This means I now have five wi-fi transmitters. I used to have endless and continuous complaints from the kids and four grandkids but now never hear a thing. Of course, I could be going deaf. No headaches though.

https://www.mwrf.com/community/rf-en...inally-cooking As for WiFi affecting humans, there's a simple test to check if you're affected: Have someone turn the source of transmission on/off randomly and make a note of when you feel any ill-effects. As far as I know, nobody has been able to reliably demonstrate that the ill-effects they feel coincide with WiFi transmissions. Ideally of course, you would need to conduct the test in a Faraday cage, since our modern environment is full radio waves, some of which are several orders of magnitudes greater than the humble WiFi access point. Even natural phenomena, such as cosmic microwave background radiation, will probably be present at higher energy levels than WiFi in some conditions. Whether radio/micro-waves pose a risk is all about power and proximity really. WiFi power levels are very low (typically less than a tenth of a Watt) and, in most cases, routers and access points are likely to be several metres away at least. The transmission power levels changes very little from one WiFi router/access point to another (they're restricted by strict regulations), so it's usually the technology (eg MIMO) and operational bandwidths and frequencies that make some devices seem more 'powerful'. In fact, you're more likely to be affected by the WiFi transmissions from the device you're operating (laptop, mobile, etc) than your router's WiFi transmissions because they're typically operated at relatively close proximity. But even a few inches away, WiFi transmissions are just too weak to be the likely cause of any ill-effects.

ZyXel is generally a good brand, and they make some good business-grade firewall/routers, but I would usually avoid WiFi repeaters altogether. The problem with repeaters is that they need a good WiFi signal in order to repeat it. Anything less than about 75% signal strength can have a detrimental effect on the reliability of the repeated WiFi link. Also, by retransmitting from one repeater to another, you're creating a WiFi chain, with the chances of connection drops increasing with every link.
My preferred solution for my business customers is to disable the router's inferior WLAN (or, preferably, purchase a business-grade router without WLAN) and use Wireless Access Points. For business-grade access points, Ubiquiti Unifi units are probably some of the best available in my experiance: https://www.ui.com/unifi/unifi-ap-ac-pro/ Ideally you will need to run a network cable to each access point, but I have had some success connecting access points via homeplug/powerline adaptors. You will also need a PoE adaptor (power 'injector') to power each of the access points (over the network cable) or a PoE network switch.

My Zyxel are MIMO access points , not repeaters.
The old Virgin router is cat 5 linked to the Super hub. I was trying to keeping it KISS.

I haven't tried Zyxel's WiFi products but I would imagine they're pretty good. I've mainly worked with their 'Zywall' USG series firewalls which I have found to be very robust and reliable.

Interesting reading. I do wonder how 5G masts are going to make me feel.

Interesting.
Well, from a conventional physics point of view at least, I would certainly argue that there's no conceivable reason that weak RF signals such as WiFi could affect humans adversely. However, at the Quantum level weird stuff happens that we may never fully understand ... Quote:
Although I'm yet to hear of a documented case of anyone being able to 'detect' the presence of weak RF fields such as WiFi. There are plenty of cases of people claiming to be affected, but I've not seen any controlled experiments where those affected correctly identify the presence and absence of the RF field. Not saying that there aren't any (and I've done very little research on the subject to be honest), I just haven't heard of any.

About 20 years ago I started working for an IT service provider in Leeds. Not long after I started with them, they moved in to a new building up the road which was directly under a 475KV power line (the really big ones). We moved all our kit in, and discovered that our CRT monitors were completely unusable due to the magnetic field from the power cables scrambling the displays. There was revolt from all the staff of course since we didn't fancy sitting in such a strong magnetic field. Some people suggested a Faraday cage in the roof void might help, but in the end management simply replaced all the CRT monitors with LCD and declared the problem fixed
I left after a couple of months. |

Have you ever held a fluorescent tube under a powerline? Pretty cool to see them glow, if a little unnerving ... https://www.larkinweb.co.uk/miscella...wer_lines.html
