    Not sure where to post this. There is no WRV200 or WRV forum. But this is close enough.

    I got a WRV200. Got it to work after fooling with it. Even got the VPN to work, with QuickVPN, after a LOT more fooling.

    Noticed some oddities:
    1. It likes to reboot a lot when making config changes, and when it does, it takes a long time to restart. (Maybe its running WIndows? :) )
    2. I have it plugged into a Surge Protector. When i turn off the surge protector, then turn back on, all my other equipment starts back up again, Except the WRV200. I have to physically unplug the small power plug from the router and plug back in to get unit to boot up. So i assume it will not survive a power outage.
    3. When i remote connect to it from outside, some of the config screens do not display properly. I haven't experienced this before with other remote connections, or other linksys/router gear.

    Just an FYI.

    any answers for the power problem are most appreciated.

    You're the second person to post any information about the WRV200 (Stonecat was the first). Stonecat never mentioned anything about power, but that doesn't mean there's something he hasn't mentioned as of yet.

    Standby, and he'll probably post shortly...

    I have noticed when you apply changes..yeah..she takes a while to bounce. An usually long period of time IMO. The first one I deployed to a client..I had many changes to make...so wow I felt that right off the bat.

    As for the power issues...I didn't stumble across that. Had it plugged into an APC batter backup (standard practice I always do for most clients...modem and router/switches get plugged into APC units)....so I didn't notice that. Interesting observation...I'll have to check that out. Getting another one in this week...so I'll get a chance.

    Hi! I see this problem also with my unit. I thought the problem was with my power adapter so I used another 12v 1 A adapter (from my old router) and tried this: powered off the unit by unplugging the adapter from the power outlet and plugged it back in right away (5-8 seconds). My unit would not power on anymore. So what i did was i unplugged-replugged the power cable from the back of my unit and voila, it came back up.

    However, this problem seem to exist only during short power fluctuation because when i left my unit unplugged from the power outlet for 1 minute, i was able to power it back on normally.

    I've been told about some strange power related behavior of the WRV200 and I've been observing some by myself.

    Looks like the device does not reset itself, when the power voltage goes low. It needs the power voltage to go below a certain limit, before a reset will happen. Also, when the power goes low, the router stops working before voltage drops to reset level. So, it can hang.

    It looks like a hardware power management problem. So, I doubt it can be dealed with by a firmware improvement. I keep my WRV200 connected to a UPS device. It seems there are no power related problems any more, besides the manual power reset routine.

    Hi All !

    I have always had power problem with WRV200, every time I have a power outage for 5 seconds or grater. The WRV200 will not come up. It must be unplugged, then I must wait 20 seconds and then And only then the LED's will turn on and router will come up. To me it appears to be a hardware problem with the router / power supply. This power problem was always in place since day 1, however, it wasn’t visible due to "minimal power problems in the past"
