i worked for a company that wanted a new office in Chicago and it fell on me to handle the internet installation. You'd think it would be as easy as, run cable to office and be done. Nope. we had to get att to run it to the d-mark then had a union company run it from the d-mark to the office, but they wouldn't touch the office. i had to get another contractor to come up and finish the wiring of the office itself. that didn't include the actually company i used for internet, that had to have their own tech come in and "install" the box (this consisted of plugging it in and watching the green lights light up). What a mess.
