If I reboot the pc everything comes back up again for a period of time. Once the download is finished I don't lose the connection again and can start seeding it. Only utorrent DOWNLOADING will cause it to take a complete dump, I can pull down hundreds of gigs over newsgroups successfully with no hiccup and I can seed forever without an issue. I can log into the pfsense panel from this desktop, and if I ping random new dns addresses it resolves dns but refuses to ping. I can continue to reach this pc from inside the network using rdp, and I can continue to reach my laptop from the internet no issue. If I download a large torrent which is well seeded and really downloads fast my pc will suddenly dump the internet connection ONLY at this pc and ONLY till I reboot. I have been struggling with a VERY strange issue using utorrent on my desktop pc. Windows k machine with 16gb ram and using a pfsense release firewall, gigabit switch.
