Upgraded my Dynalink DL-WRX36 with no issues. All is working smoothly.
n.b. For those with USB storage attached directly to your router, I had to go through the USB and SAMBA how-tos again. Config files were saved, it was just the software that needed to be reinstalled. It took me maybe 5 minutes to run through the process via SSH. Restarted SAMBA and everything was back to normal.
