Just an update on those with 1MBps Aggregate speed Canopy's. I don't think that by just updating your firmware will make your Agregate speed up to 7MBps. as I see it 5700SM is Canopy and 5760SM is Canopy Lite which was the norm that they installed these day. Also even if you manage to get that 7MBps aggregate speed you will be tied to the 384 or 512 capped by the prism or BAM (Bandwith Allocation Management) software of Smart.
the only use of updating firmware is like what extreme fusion says in the first post that he get frustrated with the dropping connection that he took updating the canopy by himself.
