Our Internet went down on Friday for about 5 hours.....Hubby called our provider and went over all the details and Whoops what do you think he found?? You got it... chewed cable...that would do it!! plus the cable leading to the router. Thank goodness Hubby was able splice the cable and had another cable to replace the router one and whew we are up and running....... The Joys of having a puppy!!
