I completely agree with Jon. I guess it is a bit difficult after the fact, but I don't understand having to take everything home after. That just seems odd. How much stuff do you have to take home?
I would ask for some space and set things up as Jon states. Personally, I would do it wired. It is only an advantage to your landlord since you would have to leave the Cat6 behind. That's kind of the renting law I believe. I can tell you that the doctor I lease from is going to have a much better area to rent with the wiring that's been done. Of course, it has to be done professionally.
I love Smartphones and use 3G, etc. But, I have to admit I know way less than what everyone is talking about on here. I have no reason not to believe them, given I am completely ignorant about the setup, but it just seems like it wouldn't be reliable. Just a guess, though.
