I have purchased the ADSL few weeks ago. I am facing issue of frequent disconnection.
I initially complained my ISP provider(mtnl) regarding the issue. After physical inspection of connection and detailed diagnostic from their end, technicians have told me there is issue with the adsl I bought recently.
I have also checked same connection using my previous modem as well and connection works perfect without any disconnection for hours non stop.
The adsl is a faulty product. I found many posts with same reviews online. Really bad testing by tp link for their products
