This is a very serious problem, and I hope that if anyone else encounter this, they find this thread.
So the problem?
Suddenly, my internet connection started getting some serious issues, and I thought my network card was singing its last song.
Websites stopped loading, applications stopped connection to the cloud etc, although some applications using direct IP-adress to connect did work, so my first thought was a DNS issue.
I started troubleshooting my PC for hours to no avail, that included tracking IP-adresses and DNS servers, changing drivers for my network card, trying other routers and whatnot. The list goes on and on.
I even re-installed the entire PC after hours of no results.
So with a clean PC, things started working again. I then started installing all my software again from scratch, and suddenly, the problem returned. So again, I started troubleshooting. After starting the PC in safe-mode with network capabilities, I figured out that it wasn't my network card.
After hours of restarting and disabling/activating processes in the background, the cultprit was obvious.
Creative Cloud caused network problems for every single application I used. But it only happened when CC started on windows initial load. I can start it afterwards with no problems.
Fresh install of PC
== Connection issues.
Solution: Turn off autostart for "Adobe Creative Cloud"
Autostart can be turned off in the application itself, or through searching "msconfig" on windows, autostart tab.
Someone have to take a look at this. I was very close to buying new hardware for my computer, or replacing the entire MOBO, CPU, RAM etc. It took my almost two days to figure this out. It was not an obvious problem.
Thanks for sharing the steps that helped resolve the issue for you, this will certainly help our future viewers.
Thank you for the suggestion. This has been causing me awful problems too and it took me forever to isolate Adobe CC as the cause. Finding your post and narrowing it down further to AutoStart was a huge time saver.
Disabling AutoStart only seems to be a temporary fix though. I still loose all network connections after a period of working in Adobe CC applications. With AutoStart off I can re-boot and get up-and-running again but its a massive inconvenience to have to do that.
If you are aware of a patch being issued or ultimate fix, please do share.
I had Adobe CC on two MacBook Pros (mine and my wife's). On mine, the CC manager rarely runs; I run it when I want to update something. On hers, it was running all the time, alongside the outdated "Adobe Updater" app.
SLOWDOWN, THEN NOTHING...
For the past 2 weeks, my internet connection has been dropping frequently. First terribly slow, then no connection for 3-4 minutes. Sometimes it would happen every 2-3 minutes, and sometimes it'd be okay for 10 minutes, but never for long. I had an ISP tech out twice -- he dutifully replaced our lines, ran all kinds of tests, but no luck. I moved the router. I replaced my router.
UNINSTALLED CC. VOILA!
I stared at the ever-present Adobe icons at the top of my wife's screen, and wondered, could Adobe CC be flooding the LAN with huge numbers of attempts to connect to Adobe... or to see whether other machines on the same LAN have proper licenses for CC, or whatever? I uninstalled all Adobe products (my wife doesn't use them anyway). Everything in our household was back to normal 90 seconds later.
And now that I think about it, each time my wife closed her MacBook over this period, things worked. Then she'd open it, and within a few minutes, every device was producing "No internet connection" messages. I didn't notice this pattern at the time. This bug kept our iPads, iPhones, MacBooks, Chromecast and Roku from accessing the web reliably for about 2 weeks. In the ~25 years since I began using computers as a kid, this is the most unforgivable, unbelievable bug I have ever encountered.
This was incredibly helpful - thank you! Why we should have to do anything like this to fix such a fundamental issue is beyond me.
I hope this is fixed soon for other users looking to get setup with the same fluidness that Adobe is well known for.

I've found something worth adding for PC users using Windows 10 (unsure how to apply this to Mac):
Happy creating! If anyone does all of this and runs into issues please let me know
I have gone through all the steps you have outlined and I still consistently get this problem.
It is definitely adobe creative cloud causing this problem because when I uninstall adobe CC the computer works fine, however, after reinstall, the problem returns.
I had this EXACT same problem. Spent time on the phone with Adobe and hours troubleshooting on my own. In the end the only thing that fixed it was changing ports on the ethernet card on the back of my computer. Very weird. Nothing else worked. It seemed to be dropping me every time I sent data and since CC was sending lots of requests I was getting dropped often.
I had a similar problem. This video saved me for big-time https://www.youtube.com/watch?v=if745CpIr_Y
