Sorry I only have this generic troubleshooting point to offer, but have you checked to see if NetworkManager might be modifying your IP routing table in unwanted ways during its operation?
From what you've described I'm under the impression that no Internet traffic needs to run through this system; perhaps NM is adding an unwanted default route?
That being said, I've heard that Nancon's Robocop is pretty decent. Has anyone played it?
Oh yeah, right. That's the problem. Consumers have too much choice now. It's not at all that 90% of those gamed now are badly lacking compared to what we used to have. It's not at all that publishers feel it's okay now to release unfinished products and continue development haphazardly after the game is put on sale. It's not at all that this leads to execs either pulling these dev resources as soon as the game had made good money to put these resources either on new projects or on DLC development. It's not at all that the industry has been pandering to the lowest common denominator for twenty years, making games that lack a challenge and reward you for nothing. It's not at all that games are produced by executives with business degrees rather than by extraordinarily passionate and talented creative typed like George Broussard, Chris Sawyer or John Carmack. It's not at all that in-game purchases through micro-transactions or even large transactions has skewed the incentive structures for both player and developer.
No, it's those pesky consumers, they've been given too much choice, they've become spoiled and entitled, so they won't be content with whatever crap a studio puts out, now. They won't just play the game and shut up.
Bro it's cool if your needs are best served by Windows or OS X but please don't lump me along with childish ideologues like OP. I've switched to Linux on my work Desktop about seven years ago, yet that didn't make me feel the need to go full-communist about it, nor do I hold it up as some kind of free market success story.
That's pretty neat. There's also an SMB client called CIFS Documents Provider (by Atsushi Wada) that's Free (MIT License) & open source.
