Firmware issues

For awhile now I have been having connectivity issues degrading operations. It all started when Internet service was temporarily lost. I had reset the modem without success. I confirmed that the problem was not with my computer by going to a wi-fi hot spot where Internet speed was extremely fast w/o any hang-ups. I do not have the expertise to explain it but I finally followed the suggestion to turn my router off and on after several seconds had passed. Result, I am back to 4G connectivity! It never hurts to "zeroize" firmware and software.
