fifteen year ago + I purchase my cable modem instead of rent and be pretty happy . lately we be experience dropped\/interrupted internet service - I assume -lrb- correctly -rrb- it be the age of the modem and research available modem . this one have a pretty good rating . I purchase at what I think be a good price -lrb- store - vs - internet -rrb- I have be satisify with its operation -lrb- no more internet interruption and I be run 2 to 4 device at any one time . I be pretty lucky that I do not have to purchase a new modem sooner - hopefully this one will last a while and keep up with technological improvement . I wish there have be better instruction on set-up ... I have to go online -lrb- after set-up -rrb- to get the manual so I know what the different light be and whether they be suppose to be amber\/green\/blue \/ solid or blinking . good product and good price - I be satisfied . now if only my cable company be as easy to contact and replace .
