Tenet request better Internet connection

[Jonathan Craig]

I am currently house hacking and the internet is spotty in the upstairs duplex that I'm renting out.  I looked into it and it seems a low voltage contractor can run a Ethernet cord upstairs to install a access point so that my tenet can have better Wifi.  The cost is 395 before tax.  I currently pay the cost of internet which is $100 every month.  Should I split with with my tenet or say she should have to pay the full cost.
