Yeah I went from having Cable to DSL on Frontier, yes speeds are alot slower then Cable, I as well dont notice a difference in the things I do online. I am very happy with Frontier too, I dont see why people have so many problems, you will find out reading other peoples reviews.
Take heed of the "other peoples reviews" my friend. You are still in the beginning stages of the partnership with frontier. Give it awhile. They will let you down. They always do. -- The weekend is here, grab a can of beer!
