I know nothing about your NAS so i cant help there. You can answer the question partially yourself by asking yourself whether
a) can you telnet/ssh into the NAS?
b) Does it have a full compiler environment? What does the command gcc say?
If these two are positive then you got a good chance.
What I can confirm is that a M1001 (as any M400) can run WPA with the new firmwares. Depending on the preinstalled firmware an update – easily done via network – may be neccessary.
