Alright, sorry in advance for the lengthy post, however, I feel the need to be thorough.  
I have a WBR1310 and I think someone is repeateadly tapping into the network despite me utilizing all security methods possible on the router.  ( I even tried mac filtering)  All it appears that they are doing is changing my router setup page password making the router inaccessible unless i reset the whole thing.  
I tried using network magic to determine if there was another computer tapping into my router and thats coming up dry.  I think it is some basement dweller with too much time on his/her hands.  
Any advice to as how I can put an end to this?
