I don't know if this is the correct forum, but I feel I should share a recent problem I had with this NAS.
After using a 500 GB Buffalo Linkstation LS-CHLF7B without any problems for a year, 3 weeks ago it started causing disabling wireless interdenrence. The NAS was located immediately next to a wired ZP 120. Once it was moved 1 metre or so away the interference stopped. The system is now working fine. Has anyone else had this problem? Presumably the proximity to the ZP 120 was the critical issue here.
