Modem and router and computer grounding

Hello,

I wanted your advice for products you offer which I should purchase based on my situation. I do not know what to buy from you regarding my situation so please help me out here.

I have a Verizon FiOS modem and router and their modem is fixed so it cannot be replaced by another. Their routers are separate units. I am able to turn the wifi off when logging into my account though I do not know if that sufficiently blocks wifi signal from getting through. I also believe that I can log directly into the router online and fine tune its settings by typing my IP address into any web browser but have not done that yet in order to double check if radio signal is disabled from there. I want to try to eliminate the wifi entirely and connect both a Macbook Air to a grounded ethernet connection from the router as well as to ground my iMac desktop computer. I need your shielded cables and grounding adapters I am presuming. But do I need a grounding adapter for the desktop computer as well? The desktop computer's power cable is all ready grounded so will the grounding adapter be necessary for that device or just a shielded cable extending from the router?

Also, what would you recommend for grounding an iPhone? The phone cannot be grounded at all times though, obviously.

I want to ground all connections and have the wifi turned off completely in order to lower EMF exposure as well as to eliminate EMI exposure from all devices.

So I want to ground connections, correct? Does the router itself need to be grounded?

Please let me know what you recommend that I pick up.

Thanks for all help!

1. So if I have grounded ports at both ends from both my modem and grounded ports on my

router as well, and then I connect your shielded cables between them and a

grounding adapter to each device (desktop and laptop), in theory should that be fine or in

theory could that create a negative energy loop and make the situation worse? Or do I not need an adapter for the desktop in this situation?

2. Also, if the ports on the modem were grounded but were not grounded on the router would that change the recommendation for the above situation, Shaun? I just ask because my current router does not have grounded ports but your router does.

3. What is the warranty on your router?

Gracious sincere thanks for all of your help!

Desktop Computers ----> Do NOT need Ethernet grounding adapter. They are grounded AND have groundable ports. They will ground your Ethernet cable - this is deal.

1. Do not connect a desktop computer to an already-grounded switch or router (with metal groundable ports) directly with a shielded ethernet cable. Use the Ethernet ground loop isolator AT the switch or router.

Laptops ----> 98% of time are NOT grounded, unless plugged into a grounded monitor (screen) or grounded printer. Very few laptops are grounded. Even 3-prong power cord laptops are usually ungrounded - the ground doesn't go all the way up to the laptop it dies in the AC adapter (charger) box.

Use the Ultimate USB to Ethernet for laptops. Then connect shielded cable. Then isolate with ethernet ground loop isolator at the switch or router if said switch/router is already grounded by something else and has metal groundable ports.

2. You could connect your modem to our router directly with a shielded ethernet cable. It probably wouldn't make much difference if our router becomes grounded or not. Then isolate every run to every computer. Ground the computer and the Ethernet cable (desktops do this automatically).

Does that make sense?

3. There is no written warranty, but we do stand behind our routers. We have really not had any issues with routers. Just do NOT use the reset button on the router, as this would erase all of our important settings. This is why we cover it with a sticker and say not to use it.

Okay, please bear with me here, thanks for your patience:

1. So, correct me if I am wrong here then, but it sounds like if my current modem has grounded ports, but my current router does not have grounded ports, then a shielded cable would be safe and fine directly from the ungrounded port router into the desktop but a grounded port router would require a loop isolator to be installed at the router port before the cable enters the pc?

2. So an unshielded cable would not create the same negative loop energy that a shielded cable would though it could theoretically pick up and transmit unwanted EMI?

Is there any possible backfiring so to speak or anything that could theoretically as a possibility go wrong with all shielded cables connecting modems and routers which all have grounded ports even if your ground loop isolators are employed?

3. Would it be more desirable to connect an unshielded cable from the grounded port modem into your router then shielded cables going out of the router? So with the grounded port modem and then your grounded port router a the ground loop isolator would be required at the router before connecting shielded cables to both the laptop and the desktop but the laptop would require your Ultimate USB To Ethernet to be connected at the laptop end? There's no possible resultant danger then of a build up of radiation through these completely shielded and grounded from all sides schemata?

Well, if anything goes wrong with your router at any point do you repair it free of charge?
