Strange request, i need to destroy the performance of a wireless router...

[LeperousDust]

Beacon Interval (msec, range: 1~65535, default: 100)
RTS Threshold (range: 256~2432, default: 2432)
Fragmentation (range: 256~2346, default: 2346, even number only)
DTIM Interval (range: 1~255, default: 3)
Wireless Mode mixed mode G mode
TX Rates (Mbps)
SSID broadcast Enable Disable

These are my options in the advanced section, what should i mess around with here to make sure it drops and is generally slow and unreliable?

As it stands it is slow and unreliable, but not enough for my flatmates to think its worth replacing this (free!!!) router. It's slowing cracking me up having to reconnect every so often and not being able to rely on it even working to connect to my server. I just want to buy another WRT but as long as this is here i'd have to foot the bill.

I've thought about microwaving it as that should kill it and be undetectable, but we've already had two routers die of natural causes so i don't think i could really convince them this has died as well. Well actually i probably could because they really don't have a clue, but thats not the point i just want this to be painfully slow for them so they can feel what i feel.

My flatmates really do actually do my head in as well before anyone asks so no worries there, i'd like to talk reasonable with them but you honestly can't bargain with these people. I do more than enough for them
