We have 2 hook-ups in one apartment. The internet comes in the wall, then it is connected to a router. Get this...a WIRED router. It is too funny i tell you. The wire goes out the same hole as our air conditioner/heater tube, goes along the outside of the balcony, across the wall, along the outside of the other balcony and then back into the apt via the hole for the a/c again. "As the crow flies" the other computer is probably 20 feet away from the internet plug, but there must be twice that length in wire!
It is so absolutely absurd it's adorable. But it works fine. We can both watch videos if we want. We did have to pay for the router and install ourselves, about 114 yuan in total, but my school makes us pay for our own internet as well (700 for a year) so it was no biggee.
