md5sum is how Odin checks for file continuity (you sound check it yourself on ROMs) to ensure that the file you have is the same as the original. Wifi connection is recommended for files this large. Also download on your PC if possible (it will save you a step in the end). Some browsers have .tar files blacklisted and will download them as a zip, if this happens change your settings and redownload.
