@rafi NO. I had the exact same problem with 2.0.1, low speeds, "wave" download pattern, never hitting top speed, and just general buggyness. I tried every damn suggestion i could find in the support forums, I fiddled with my router settings, I did EVERYTHING i could think of, and still no luck. I finally got tired and removed 2.0.1, reinstalled 1.8.5 and lo and behold, everything works perfectly again. No "waves", no low download speeds, hitting 2.2 MB/s easily. Conclusion: 2.0 generally broke things in a very bad way, and 2.0.1 didn't fix anything. I'm gonna keep using 1.8.5 for the foreseeable futurure. IF 2.x ever gets fixed i'll switch, but i'm not holding my breath. It's just not worth the hassle, and there are no compelling features yet that would make me want to go through this again.
