Well, I am from Hong Kong...and I wish you could take my advice also.
My router is WZH-HR-300NH.
My wish list is as follows:
1) function to assign IP address of LAN computers according to their MAC
addresses
2) Wireless power adjustment
3) USB - printer server function
4) range of IP address could be set even when DHCP disabled
5) OpenVPN server function
6) improvement of torrent BT download so that files with different languages
could be downloaded & read, files within a torrent could be selected to be
downloaded
7) jumbo frame function (allow enable/disable & value setting)
8) QoS for allocation of bandwidth to individual IP
9) naming of port forwarding profile allows space or underscore
10) WDS
11) traffic monitoring & management function (for individual IP)
12) telnet server & client
13) SSH server & client
14) green ethernet function
quite a long list but such features are awesome...
BTW, I wish Buffalo could really keep up to have the firmware update more frequently to add more values to their products. It appears that Buffalo has more support to japan users than others and the firmware update is not frequent as other brands.
