For an answer on my internet connection: Yes it is 3g/4g wireless router that supports 15 local wifi connections as my ‘home system’. It does have a single ethernet port that can be used (but I am not using it) The product is marketed thru my cell phone provider… but I think it is made by zte or netgear.
My location has no terrestrial broadband. It is tough to even get a pots dialup line. So I have limited options.
