You want to restart the player after any configuration changes. Remember, these players are actually just small computers and like a computer, you have to reboot for the changes to take effect.
I've updated my over the internet connection and with the ISO. I think the whole wireless update thing is way overblown to be honest. Burning a disc and updating that way is both much faster and safer in my opinion. The only downside is you usually have to wait a little longer to get the ISO. But you also have a little more time for others to find any nasty bugs first also.
You have to image the disk, you can't just burn it. There are fiirmware links, full instructions and even a link to a disk imager in this post, courtesy of Adam Barrat: http://www.hometheaterforum.com/htf/...8&postcount=25
I did it the other day and it was a snap. Much easier than wrestling with the not-quite-ready-for-prime-time ethernet port.
What exactly worked for you, Jeremy? It appears as though you followed Mark's advice and re-booted the machine after changing some settings, but what settings did you change in order to connect to the Tosh server? DHCP and DNS on?
