Someone has asked me to assist with modifications of their home network. They want to eliminate the wireless function and have only hard wired to minimize EMF radiation which is associated with wireless networking. Current hardware: Cable Modem ISP Provided Wireless/Hardwired Router (4 Hard Wire Ethernet Connections) 2 Desktop PC's (One PC is currently hard wired with no wireless connection. The other PC is currently wireless. It is planned to run a patch cable between one of the remaining three (3) ISP's Router's Ethernet Connections and that PC's Ethernet Connection and turn off wireless function on that PC.) That leaves two Ethernet Connections available on the ISP's Router. There are up to four (4) tablets (Each with a USBC connector) that may be connected to the Internet at the same time. What kind of hardware do I need to allow for intermittent Tablet hard wired connections to the Internet? USBC to Ethernet Adapters? Recommended Model(s)? Unmanaged 4 Port Ethernet Switch? Etc. Thanks in Advance.
I can't contribute to how to connect the tablets to Ethernet, though I think a simple 4- or 8-port switch will do the job with appropriate adapters. However, you'll have to use all the tablets in the same room as they'll be tethered to the switch (obviously)! But, I can recommend looking into Powerline adapters to get Ethernet throughout the house (though house power is another source of EMF, it's already there). A neighbour had been using one successfully for about the last 10 years, and they've only improved over the years. YMMV of course, but it might be worth trying before laying cable throughout the house, and with several devices you could have multiple rooms Ethernet accessible.
If the ISP provided device is not indeed a gateway; i.e. providing wireless connectivity to ISP desktop TV devices, just disable router's Wi-Fi connections.
I just visited a very large computer hardware seller and they said that the Big Problem is the compatibility of each tablet to the required USBC to Ethernet Adapter which is required to attached to the needed Switch. Some work and some don't. I have just requested for more information on the Tablets so that I can investigate. The Tablets are, for sure, not Windows. I looked up an 'example' of a possible USBC to Ethernet adapter as follows: https://www.amazon.com/AmazonBasics-Aluminum-Gigabit-Ethernet-Adapter/dp/B08989MYQ2/ If it turns out that the Tablets are OK, I need the following: 6+ Port Unmanaged Switch CAT5+ Ethernet Cable between Samsung TV and the 6+Port Switch 4 USBC to Ethernet Adapters, maybe like the one above 4 CAT5+ Ethernet Cables between each Tablet and the 6+Port Switch 1 Long CAT5+ Ethernet Cable between the 6+ Port Switch and the ISP's Router. Did I miss anything? Thanks In Advance.
I have 2 USBC to ethernet adapters. Simplecom and Unitek. The Amazon one looks fine. When I install Win11 on one of my computers, the setup doesn't detect internet via a cable to my network card. However each of the above adapters detect the internet.
I have more details now. One of the Tablets 'should' work since it has a later OS version. The other three tablets will not work with current older OS. The plan is now, over the next several weeks, to... 1. Obtain and install a 8 port switch. 2. Connect the 8 port switch to the Samsung Ethernet port. 3. Connect the 8 port switch to the one remaining unused Ethernet port on the ISP's Router. 4. Make sure that the two Desktop PC are working OK in hard wired mode. 5. Purchase and connect one USBC to ethernet adapter to the 8 port switch. 6. Connect the Tablet with the latest OS to the USBC end of the Ethernet Adapter. 7. Check to see if the Tablet can connect to the Internet hard wired. Troubleshoot, as necessary. 8. Login to the ISP's Router and Turn Off the Wireless Functionality. 9. Check all devices to make sure that they have connection. 10. If the Tablet is working OK hard wired, then later purchase three (3) new later OS Tablets and the necessary hardware and get them connected. This step may be over a few days to weeks. 11. If things work out OK for this setup then purchase necessary hardware for another house and do the same setup there. The four (4) tablets are to 'float' between the two houses. I try to keep you up to date on how things work out.
~ Off Topic Remarks Removed ~ But what I wondered about is if you can even disable 4G and WIFI from tablets? That's the first thing I always do, I disable WIFI and Bluetooth from my smart TV, desktop and laptops. But I figured this isn't possible on smartphones and tablets.
You can turn them off. Does that actually disable the transmitter? I guess you'd need some kind of tester to verify.
I never even noticed this stuff. And good point, I aways wonder if this stuff is really turned off. I did notice that my smart TV is not sending any Bluetooth signal, I have checked this with a tool like BluetoothView. So I guess this says something. https://www.nirsoft.net/utils/bluetooth_viewer.html Thanks for the tip T-RHex.
On my wired network I always turn off wi-fi in my router and by using airplane mode and that mode can sometimes be turned on from your keyboard (has a little airplane mode key), one of my Lenovo laptops has it on it's keyboard at F7 I'm not sure on a pc keyboard that doesn't have the symbol which key is the airplane mode key. If you have that list of local connections of neighbours' wi-fi...it will disappear instantly when you hit the airplane mode key or setting. I always imagine that it takes some sort of energy to make those connections and in turning airplane mode on, then things are more secure and use less power, even if it's not a lot of power.
