the guy was a plank. get them back out. your signal levels aren't right, could be your cables, the cab you feed off or a network fault. if you have broadband, use a speed checker as most will tell you how many people are on vm in your neighborhood and what speeds they get, lots of vm areas have too many customers running off one cab
