1 Mega Byte = 8,000,000 bits
MB or mb? MB = Mebibytes, mb = mebibits. (Old style Megabytes and megabits) For MB, just divide by 1024. 10160 MB (or 9.92 GB) For mb, multiply by 8 (8 bits = 1 byte) = 83233402.8 kbits, or 81282.6 mbits, or 79.37 gbits.

NO, because a high speed USB only capable on a 480 and 12 mbits/second while your non hi speed port is only 1.5 mbits/second. but you can use a USB 2.0 because it is capable on a 480, 12 and 1.5 mbits/sec. ok
640 Kilobyte is equal to 5243000 bits (1 KB = 8192 bits)
15.2 Megabits * 1024 (2^10) = 15'564.8 Kbits
The 512 kbits is your connection from your modem to your ISP. The other one is from your PC to the modem, it's called LAN. If send someting on Internet you willn't get more than 512 kbits.
iSCSI runs over Ethernet so it is limited by the speed of your network. iSCSI theoretically runs at 100Mbit, 1000Mbit or 10000Mbit. However there are many other factors that influence its actual speed.
Malicious software, viruses maybe even programs running in the background which use the connection. Maybe you are confusing Mbits with Mbytes. Big difference. Try to run anti-malware programs and anti-virus scanners for starters. Or, just call your provider. They will guide you through a process and will explain a lot.
