I am having this problem for the past 4 weeks that i am not able to open websites like Hotmail,Hi5,answers.yahoo etc and there may be many more.I checked the pings for all the sites that i couldn't open the result was clean nice ping of about latency 300ms. I tried using different browsers and and even reformatted my pc but still have the same problem. Whenever i try to upload anything it does not upload and get disconnected frequently even though the adsl light is stable.When i called the costumer care they were not able to fix this problem and said thet it may be a problem at their end and will be fixed in about 2 days and it has been 22 days and the problem is not yet fixed.I use a Wireless modem from MTNL model T-KD 318-EW and when i used my friends modem it worked fine. I can't visit the websites from my laptop but from my friends house i can open those websies without any problem and no DCs(Dis Connects).I can download some files with an average downlload speed of 214kbps.When i try checking my download speed form speedtest.net it doesnt show and upload. Please help
