Recomend me a Router/Modem

http://www.asus.com/us/Networking/RTN66U/

The advice I've gotten from security reviews and networking research is to NOT use combo modem/routers.

The router linked above is the latest iteration of the best bang-for-the-buck router I've ever owned. I got the RT-N65U two years ago to replace "D-Link" and have not regretted it.

Look to sites such as: http://www.tomshardware.org/ and http://www.smallnetbuilder.com/
for reviews. I recommend starting with "Your Router's Security Stinks: Here's How to Fix It" at Tomshardware.org.

I hope this helps.
