Cons:
1) Request Time Out / Destination Host Unreachable.problem EVERYDAY!
2) everyday need to call CC / Local Cable guy to fix it.
3) If you are from daksineswar area, DO NOT TAKE THIS CONNECTION FROM PRASUN-DA /Krishna. They are complete ass*oles. If any problem occurs, they wont solve it- and even wont pick up your phones
4) Monthly rental depends on cable guys choice .
