I've gone through windows xp, 7, 8, Ubuntu derivatives by the dozen, slackware, debian, arch, and even fiddle with gentoo.
Windows connects straight away no problems and a rock solid connection.
Linux, no matter the kernal, takes a bit to connect (anywhere from a couple minutes to as long as a half hour, occasionally it'll connect straight on boot but that's rare.) Once connected though very stable/steady connection.
ChromeOS? Connects to router but internet connection is... at best splotchy. Dev mode/Shell tells me, if Ping is anything togo by, I'll get response from a few pings, drop a few more, get some hits, then drop either in clusters of three or four or as many as a dozen.
Ping on any other linux based OS gives a solid connection every time. Also if I have a connection then sleep mode seems to kill it, ditto with switching users (I'd originally tried waiting for Guest to get a connection, surf for a bit, then try signing on as Me.) Very annoying.
Had wanted to try doing nanowrimo this year using ChromeOS just to see if I could get it done.
