I buy this because I have dropuot problem in my bedroom use Comcast triple Play digital . I be allway get a notice to subscribe to a channel that I have be watch 5 minute before while channel surfing . all Comcast would do be replace the cable end , -lrb- I have a pile of they -rrb- . in my original set up I have one splitter for my cable modem\/phone modem that then go to three splitter for my three tv 's . I simply replace both splitter with this . the tv 's all work better and no problem with my internet or phone .
