I have had a number of problems getting W202 errors. These are usually fixed by a manual unplugging/replugging of the ethernet and power on the slingbox. This lasts for a few days before the errors return. I have read that setting up a static ip may fix the problem...but am somewhat lost as to how to go about this.
I have found this: http://homepage.mac.com/car1son/static_port_fwd_staticip.html
And also this: https://discussions.apple.com/thread/957814?start=0&tstart=0 (which makes sense though I don't know about the mac address)
Any help or guidance would be appreciated.
