I installed over the "Firmware Tomato" what happens without problems following the instructions because this router is compatible. IEnsuite in the setting offered by Tomato, it is possible to:
+ Create multiple WiFi access point (one private, one for the guests etc ...)
+ To manage the power of the WiFi signal to increase the 42mw to 400mw (I have not hitherto ssay)
+ To make a VPN server to connect to its network of "house" from the outside.
More sharing a USB hard drive, but over WiFi, I find the speed execellent not to copy large files. Gigabit wired in is better (transfer to 50MB / s can be more with other HDD).
In cons, I would say that it heats a little (it's warm)
