How long will it take to transfer a2GB file at 56 Mbps?
30 min 476195 sec (30.47min).
___________________
I worked it out as:
100MB = 100*1024*1024*8 = 838,860,800 bits
838,860,800/1024 = 819200 Kb
Thus it will take approximately 819200/56 = 14629 seconds (to the nearest second) = 4.06 hours approximately (if it runs at full speed the whole time)!
[Answer is assuming 56kbps means 56 kilobits per second (not Kilobytes). If you meant 56 kBps then the first answer above would be right.]

Comcast modem default ip address?
Depending on the Make & Model of your modem, you are likely best off heading to the modem manufacturer's website, looking for the PDF or manual for the modem. If the device offers a "health" or administration page, the preferred method to access it would be found there.
Look on the bottom of your modem, it's there on most.
IP addresses are dynamic which means it creates the ip address automatically so static IP's will not work and they are never printed on any modems because each location is different. Or if you are trying to get into the GUI of the modem you type in 192.168.100.1

Can you connect a router into a network that uses a switch?
The answer is yes. If you need more information, please be more specific on what it is you're trying to do.
Yes. Generally you plug your internet connection into the router, then an ethernet wire from the router to the switch. More than likely, depending on what set-up you previously had, your going to have to change your tcp/ip settings. I could probably guess what set-up you have... but you'll have to be more specific before we can give more advice.
