from what i understand you would need consent for a private operator too.
in any case, you are asking for trouble by getting a wired connection without getting it approved by your landlord.
Of course i will get approval from my landlord but consent letter and kind of paper work he would not prefer to do. Earlier we opted for airtel Broadband at another place but at that time airtel did not ask for any letter from landlord, only rent agreement was required so thought it would be easier and faster to get connection from private ISPs.
