THIS ROUTER DESERVES ZERO STARS!!!I've set up many routers. THis think is maddening.So i get the new router and automatically upgrade it to the latest software release before any configuration ( v4.2.1.02 (Jan 18 2012 14:10:55))Then I have one simple task - Forward incoming port 41790 to 192.168.0.50.That's it - the simplest feature on any $70 router on the planet. Guess what 3 hours later and the friggin thing still cannon do a simple port forward. I disabled the firewall, set up aUPNP service, set the software DMZ to the IP everything.Still doesnt work - Then I search online and find this has been a probelem with this router since 2007 thru three hardware revs and countless firmware revs. What crap.I WILL NEVER EVER BUY ANOTHER CISCO ROUTER - THEY HAVE BURNED ME OF THE BRAND FOREVER>BEWARE _ THIS ROUTER WILL NOT WORK CORRECTLY _ EVER!!!
