My wife and I live in an area where Satellite Internet and Phone are the only option unfortunately. So our complex setup involves a modem, router and telephone adapter. My wife's health is such that she would like to remove the presence of WiFi signals in the house if possible. This isn't as ludicrous as it sounds. First, her laptop doesn't work with WiFi and my office (and desktop computer) are remote from the router so we work successfully with HomePlugs and don't actually need WiFi signals. My question is, is it possible somehow to remove the router and its WiFi signals from the system. There are three LAN cables that go into the back of the router, one from the phone adapter, one from the modem and one to the neaby HomePlug. I can't simply plug two of the cables into the modem even if that made sense, and I'm not sure it does, because the modem has only one LAN input. Thoughts please.

I have to ask why you don't configure the router's radio to "OFF." Every router I've configured over the past 2 decades has this.

Okay, you've already lost me. There appear to be no controls on the router, a Linksys E1200, apart from the power switch. How does one go about configuring it, please?

You are right. There are few controls "on" the router. For control we usually point a web browser at the router, log in and configure.

The product manual is at https://www.linksys.com/us/support-product?pid=01t80000003KRTzAAO and small world, I have setup this model in the past.

Page 28 of http://downloads.linksys.com/downloads/userguide/E_Series_UG_E900Rev_3425-01486_Web.pdf notes the disabled feature.
Looks like you're all set.

Thanks, this is helpful. The system was setup by the Satellite people so I've no idea what was involved.

we usually point a web browser at the router, log in and configure.

Can you clarify what this means exactly? First, do I have to plug my wife's laptop directly into the router or can I access it through the homeplug system? Second, what webpage do I need to access? Third, I'm not aware of any log in information I've been given. Also do I need to download any software?

Thanks for your patience with a complete novice when it comes to networks.

Actually, I've managed to access Linksys using http://191.168.1.1 on my desktop but don't have a log in code or password. Presumably I will need to contact my supplier.

If you've done a factory reset you might try looking it up on router default passwords

Thanks for that. I managed to get in okay. Presumably I merely disable SSID Broadcast on the two Wireless tabs I show screen shots for. That should remove the WiFi signal but leave me able to access the internet via LAN cables and homeplugs. Am I right?

Sorry, that's not what I should be doing. On the basic wireless tab I think I should be changing from Mixed to Disabled on thepull down menu in the enclosed screenshot. This is for 2.4GHz settings. There doesn't appear to configuration for 5GHZ.

The manual wrote "Disabled, which disables the 5 .0 GHz band on this router"

You're very close to done.

Can't find that quote. So all I have to do is change the pull-down menu for Network mode in Basic Wireless Settings from Mixed to Disabled and click on Save the Settings and I'm done?

I know a lot of folk hate using product manuals. I'll quote them and leave it at that.

-> I think you got it done.

Thanks very much.

Off topic but I have to ask:-

You do realise that WHO (and countless other bodies) have found no link between WiFi signals and bad effects on health, unless the wifi switch you are using is not compliant with the local standards.

Could it be that the wifi is possibly interfering with a medical device? Other than that (and I don't know if it is even possible) I can't imagine that there are any health effects from non-ionizing radiation.
