Well I wouldn't put alot of stock in what a cable tech tells you. Unfortunate condemnation of an entire class of people when I am sure there are some that know what they are talking about. However based on my limited experience with tech support with a cable company as your ISP, they don't. I haven't talked to someone with a clue yet anyway. Though I don't really call for tech support. More to just check down nodes, change the MAC on a newly purchased cable modem etc.. Short story is take what they tell you with a grain of salt.
