Is your building rent controlled?
If not, I suspect your landlord is short sighted. I am curious to see whether property values will start to diverge based on quality of internet access. With more people wanting to work from home, I think availability, speed, cost, and quality of Internet access will have an impact on property values.
(Of course, you're in Manhattan, which means landlords can do almost anything and still charge insane rents, so this may not apply to you. Sorry.)
