WRV200 and a blinking wireless led

    It's a little bit strange behaviour of my WRV200 router: the wireless led blinks all the time, although there isn't any activities on wireless network. I expect the led blinks only when some wireless device is connected with the router, but there isn't any difference if the wireless part is busy or not.

    It only stops blinking if the wireless option is disabled on the router.

    I use WEP security, disable the braoadcasting and even if I lock to only one MAC address - the led blinks all the time and I'm sure nobody uses my router as free internet. Upgrading to 1.00.29 Firmware doesn't change it.

    Is there a workaround about that ?

    the led blinks when wireless is enabled; that's all there is to it(i don't like this behaviour either) and there is no workaround as it works this way by design.

    The led blinks because there are a lot of wireless activity, the wrv200 sends beacons packets every 100 ms by default. So the led blinks 10 times by second.

    I changed de beacon interval to 1000 ms, then the led blinks once a second, so I can view if the wireless signal is idle or if there are some clients using it (because it starts to blink faster)

    It's not the solution, but is easy to view if wireless is in use...

    Oh, this is interesting.

    How does changing the "de beacon" interval affect to the wireless performances? What actually beacon packets are?

    iirc, the beacon packet is just your SSID, so discovery tools like windows zero config and such can find you. The longer between beacons, the more likely is it that when you hit that "find wireless" button, you'll miss your AP ...

    I'm pretty sure tho, once you're associated with an AP, you don't need to worry about beacon intervals. (I could and have been wrong in the past however :) )
