My favorite cafe owner would just look like a deer in the headlights over 
this. She doesn't do online at all and just provides the wifi for 
customers. I'm not sure who set it up for her. Her CC reader is dial-up.

I'm pretty new myself to hacking a consumer router so I don't know what's 
even possible. Likely her router doesn't even have any settings to deal 
with bloat. What can you do without risking breaking things and ending up 
with an angry owner?
