Here is the situation:
I have a router that has been hijacked/hacked recently and we're attempting to up the security. Whilst I know MAC address filtering can easily bypassed, I'd like to clarify one point.
We have a laptop. Its WIRELESS MAC address is registered on the router, the Ethernet MAC address is not. If the user of the laptop is having Internet connection problems, someone else has suggested that even the physical Ethernet connection will help to bolster the wireless connection, despite the Ethernet MAC address not being registered.
I believe this is wrong but I'd like someone with more expertise on the matter to give me a hand.
