I have a Sify connection.Whenever I try to download large files , the download fails..for eg when I try to download a 100 MB file from link-removed, it only downloads about 20 -30 MB and says download complete.The resulting file is hence corrupt & I cannot use it.Why does this happen and how to overcome this problem? I have a monthly unlimited plan and do not use any download manager becoz it is not supported by the site.
