I might not be up to date. Here is where I am ...
Ping is not the same as http(s). There's obviously something preventing the Win10/alienware boxes from playing nice with the combox.
My understanding of alienware is it's meant to optimize gaming experience, which may suggest it may not be all that conservative in implementing protocol level stuff in firmware, which might work well in games, but break something with the combox. Pure guesswork though.
My thought was there may be a bios option which makes the ethernet behave in a way that makes nice with the combox.
Ok Dusty, I just checked my work lap top. It was also running 1607, and had no trouble running the combox browser page. As I really dislike windows forcing auto updates down everyone's throat and giving power users no option as to how updates are received as they had for years, the only work around is to set your wifi connection to "metered" so windows only updates when you tell it. Tonight I told it to update, now running 1803. Combox still runs fine in a browser - Windows 10 Pro 64-bit. But if I turn my Antivirus on, combox browser window becomes very sluggish and stops responding for a few seconds, but does not crash (at least not yet). Yet combox with antivirus on is nearly impossible to use.
