Just installed a new 802.11g Linksys router for the GF connected to her cable modem. I noticed that even when our notebooks are suspended (lid down) the WiFi indicator on the router was blinking to indicate activity.

I do know from scanning that there are at least 3 WiFi networks accessible from within her condo. I'm wondering if this WiFi chatter is responsible for the flickering indicator, or if the indicator only shows "valid" WiFi traffic through the router.

I did lock it down with WEP (would have used WPA, but I'm still on 802.11b), MAC filtering and disabling the SSID broadcast. I can't believe that even in a worst-case scenario, if someone had the utilities to do so that they would have cracked the WEP within 5 minutes of me turning it on.

Am I being a little bit paranoid or is this nothing to worry about? I'm not familiar with Linksys wireless, and my own NetGear router doesn't show the same behavior in my apartment (where I have at least two WiFi networks accessible).

Thanks for any input!

Cheers,
KV
