i am currently using DSL2540T (D-Link)
the problem is, everytime my housemate switches on her comp,
the connection slows down a lot..sometimes i can't even load up a page(getting errors)

when i approached her, she admitted to donwloading some shows, buffering shows...
the thing that i want to ask is this,
1) how to check whether my router NAT table is full or not
2) how to use QoS to limit her bandwidth

can someone teach me step by step on how to set the QoS rule..?
help pls!!!!!
