He's not the only one: since the past four days something has gone terribly wrong with my connection. Before that, I used to download from Rapidshare or Megaupload at around 200 kbps (fluctuating between 180 to 220 kpbs), then suddenly now it has fallen to around 10 to 20 kbps. Utorrent starts off very slowly, with the speed increasing from about 50 kpbs at the beginning to finally 200 kbps (at times only) but after almost half an hour > so what is it doing, searching for seeds all this time?

Actually, I read a post by Essbebe and downloaded Connection Booster, and earlier I had a problem with the connecting - my connection would keep breaking for the first two minutes before becoming stable. I also changed from ADSL2+ with EC mode with Bitswap disabled to G.DMT and FDM mode with Bitswap enabled, and the connection seems to have become more stable, but I still can't download from Rapidshare. I've changed it back to ADSL2+. With Internet Download Manager I could get above 200 kpbs speeds, now even with it, I get only around 20 kbps. Yesterday in the evening I downloaded a file from RS and it downloaded at full speed, which set me thinking if BSNL is throttling the speeds during the free nighttime.

I am copying everything from the 192.168.1.1 page here:

Summary:
Model Name: MT880

DSP Version: D.57.2.17
Operation mode: ADSL2+

I started Utorrent at about four o'clock, and I got about 140 kpbs speed, and this continued till about seven, even though the torrents were all well-seeded ones. Then all of a sudden after seven, the speed jumped to 220 kpbs and stayed that way till the end.

Anyway, bsnl provided me with a new port and all seems to be well now. They said my port was damaged/corrupt.
