Is there anything in router settings to prevent certain laptops on the wlan network to be disguised. For example, I need to find a setting where the router doesn't show that i'm downloading/uploading anything. Everytime I start downloading something or uploading something the WLAN light on the router flickers like crazy. Is there anything to disable that? I need to figure this out so everytime I get online my douchebag roommate doesn't know. Thanks. I'm willin to literally open the freakin router up and cut a certain cable so it just looks static instead of it flickering. Any help would be greatly appreciated. I have an AMBIT Broadband router.
