For the past week I am facing very slow upload speed and frequent internet disconnections.The upload speed is almost zero (200-300 kbps) while the download speed is working fine. Also the internet stops working for a few minutes frequently but resumes itself. While the disconnection happens there is no loss of signal just there is no transmission of data. During this time if I run diagnostics on my router it shows the internet is working fine although I am unable to load anything. The local authorities are clueless about the issue.Can anyone help me out ?
