Jon, I have the modem provided by Charter...and it's the 7th or 8th modem they provided during the months of setting up internet here. I can't get a strong enough signal via WiFi even when I'm right next to the modem.

How can I tell how fast/strong the signal is...how many mb? I'm afraid to mess with any of our painfully acquired Charter setup to connect to the real world, as, after a few months of off and on 'net and a series of different techs from Charter (each of which claimed the previous fellow had "done it all wrong") we've had good internet service. Can't say the same for TV, though! In addition, Charter has failed to answer any of my questions about closed captions, which we're supposed to have...but only can get on three junk channels. If there were another service available in our isolated location, we'd have it!

I also don't know anything about a setting on my Samsung smartphone for WiFi calling. The smartphone techs in cities can't even comprehend not having cell service, are stunned by the very idea. I've found it extremely difficult to get help or info because all they know is having stable service. In this little town, City Hall has no cell service, unless you can connect to their WiFi. A business less than a quarter mile from the only cell tower in town has zero reception, even though there's nothing between the tower and the store. I can handle computer tech stuff, but dealing with the lack of cell service is apparently far above my pay grade!
