If you want to go with this kind of router (cheap, wireless, simple), i 
would then recommend a Linksys WRT-54GL (The trailing "L" is very 
important, about 50$) and replace the stock firmware with DD-WRT (GPL). 
  DD-WRT is real nice, simple and have a lot of interesting features. 
It is less flexible than the solutions below.

You could go with OpenWRT and the same Linksys WRT-54GL if you're a 
Linux savvy.

If you have an old PC laying around, i'd then recommend pfSense.  I have 
  pfSense firewalls on some sites and it runs very very well.

If you prefer to go with SBC (Single Board Computer like a Soekris 
net45xx/net48xx or WRAP board), then you have a choice between mOnOwall 
and pfSense (and many others but those 2 are simple yet powerful).

I have a couple of SBC boxes installed at my clients' offices running 
mOnOwall (WRAP SBC Boards) and they do a very good job.  They are very 
energy efficient with small footprint.

Finally, you could go for a used Cisco Router (something like a 2600 
series) if you like Cisco like a do.  But it's not an easy solution, 
it's very command line centric and you could have a hard time decrypting 
the very large command list of IOS (and getting used to it).


Hope this helped.
