Thanks for the detailed explanation about ADSL connection @"Hidden Refuge".  Wow!  All of it makes sense as this is how I was set up in the UAE when I had a line.  An ISP technician had to come in to set my computer up special - think there was a modem involved.  And now I understand why the line that went into my computer - the ethernet cable - wouldn't work on my laptop as well.  My laptop would have had to be set up similarly first for the cable to have worked on it as well.

I wonder whether there is a possibility for someone to develop a device that blocks all electronic probes?  Like if one presses a button of a specific anti-device, then no signals can be received or sent on the wavelength that phones and internet operate?  I just googled this and found a portable WiFi Jammer - wonder whether this may be an answer:

This one looks very attractive (very expensive) but looks like a good idea - it's a portable device:

EO-10 High Power Military WiFi Cell Phone GPS Lojack 433/315/868MHz Jammer

As the newest military-grade product, the advantages of this jammer are obvious. It has the characteristics of large jamming range and multiple jamming frequencies bands. It can block all cell phone signal(GSM/CDMA, 3G, 4G, 4G LTE), Lojack, GPS, WiFi, Walkie-Talkie UHF/VHF and RF signals like 315 MHz, 433 MHz, 868 MHz.

This one is a little cheaper - more my size.
