I have used the RVL200 for over a year with some success and a few frustrations. Its main failing is that it occasionally gave up trying to auto-reconnect the WAN interface after a reboot, requiring non-tech staff to login to the router and manually connect the WAN interface. For a router marketed as a branch office router, this isn't an ideal situation. Upgrading to the latest official/unofficial firmware yields the same results!
Unfortunately I've had to remove the router from service, because it now always, rather than occassionally, fails to auto-reconnect the WAN interface. The complaints from the users got too much!
