I have the 590NU plan in Mumbai (Charkop exchange). Mine is a peculiar problem, which i'm facing from the past 15~20 days. I have problems uploading files or attaching files to say hotmail etc. The ADSL Router lites are all up all the time. I have installed BW meter which shows there is very little or no upload traffic a lot of times. Downloading files on the other hand is a breeze...What could be the problem...? Thanks in advance....
