Internet troubles...

I know of 1 similar case, Daughter lives in apartment complex. My grandson misplaced his cell phone. Neighbor boy returned it. A week later she figured out that the neighbor had hacked her wifi.
Password change cut them off, solved the problem.
When AT&T was running fiber optic in this area and offering what they call "Uverse" their engineer told me that since my home was well over 5000 feet from the actual fiber optic cable ( it goes back into the wires from there ) my service wouldn't be great. Months later their introductory rates and 100 dollar bonus check for switching made it worth a try. I may never know what "great" is. What I have is very good, a heck of a lot better than previous DSL, and well worth what I'm paying ( until that introductory rate expires ).
