i have a couple questions.im switching to fios at the end of the month i have a question about their internet technology. when i had comcast i had around 6mb download and around 1mb upload. but whaen someone was uploading from me it slowed down my download speed. is this a problem with my computer not being able to send and receive information at that high of a speed? or is it the cable connection? does fiber optics solve this problem?
