Utorrent suddenly slows down

[neokenzo]

I've been using utorrent for a while now and my upload and download speed has been good. About a year ago it suddenly my upload and download went really slow. I tried a lot of things back then and tried a lot of utorrent clients and after trying a lot of things, it was fine again when I was usin utorrent 1.7.7. I kept on using that because I dont know what I did to fix it and I dont want to jinx it again.

For the past year I have had no problems with utorrent at all until about a few weeks ago. I cant remember what I did the last time but I tried a lot of utorrent versions but it still not working. So I decided to use the latest utorrent version, still no change. Suddenly, the on the weekend it was downloading and uploading at full speed again and then it stopped again. I dont know whats going on. I tried a lof of setting but nothing have changed.

Basically, anyone knows why or any suggestions to fix this problem?

Thanks in advance.

Who is your internet provider?

IrishBroadband. I've been with them for years.

I probably should mention this as well. I dont know when both of these started but I only noticed it since everything slowed down.

1. On Speedtest, my upload only goes up to 250kb/s eventhough I can upload using web/ftp up to 2700kb/s.

2. When I test my ports are open, it says close and then I hit refresh, it says open. Sometime it says open and I hit refresh and it says close.

When I had my speed back during the weekend, both the above was still like that.
